Summary:
Looks like spaces in function names can happen, but the lib we use for parsing stacktraces doesn't support that. As result, when error is thrown in global scope, new JSC puts "global code" as function name, our parser chokes on it and thinks "global code@http://...." is a file name and sends it to packager. The packager can't resolve that URL and fails the whole symbolication request.
Longer term fix here: https://github.com/errwischt/stacktrace-parser/pull/5

* Next version of Jest doesn't allow non test files in __tests__ folders.
* I'm trying to switch all tests off of jsdom on react-native. This should save 500ms of time when running a single test because jsdom is slow to load and react-native is also not supposed to run in a DOM environment, so let's not pretend we are providing the DOM in tests.
* Make the bridge config configurable so that when we disable automocking and we reset the registry we can redefine the value.
Oh also, stop using lodash in Server.js. First off, lodash 3 doesn't work in Jest's node env because it does some crazy stuff, second because we don't need to load all of lodash for debounce.

Summary:
This will allow consumers to supply their own transformer to all `react-native` cli commands by simply implementing `rn-cli.config.js` and overriding `getTransformModulePath()`. That way they don't have to fork various parts of the iOS and Android build system that React Native already provides just to add a `--transformer` command line argument.
**Test plan:** Applied this patch to the React Native version in my app, implemented `getTransformModulePath()` in my `rn-cli.config.js`, and verified that my custom transformer is invoked.

Summary:
When an asset is included in a module, and the directory for that asset can't be found in any of the roots, it is hard to debug that, because the error message contains neither the name of the requested file, the sub directory it is located in, nor the roots that have been searched for it. It becomes more difficult, because that exception is created asynchronously. It contains the calling promise code.
This diff makes the error message more useful by including the name of the file, the sub directory, and the roots.

Summary:
The way we currently symbolicate JS stack traces in RN during development time
(e.g. inside the RedBox) is the following: we download the source map from RN,
parse it and use `source-map` find original file/line numbers. All happens
inside running JSC VM in a simulator.
The problem with this approach is that the source map size is pretty big and it
is very expensive to load/parse.
Before we load sourcemaps:
{F60869250}
After we load sourcemaps:
{F60869249}
In the past it wasn't a big problem, however the sourcemap file is only getting
larger and soon we will be loading it for yellow boxes too: https://github.com/facebook/react-native/pull/7459
Moving stack trace symbolication to server side will let us:
- save a bunch of memory on device
- improve performance (no need to JSON serialize/deserialize and transfer sourcemap via HTTP and bridge)
- remove ugly workaround with `RCTExceptionsManager.updateExceptionMessage`
- we will be able to symbolicate from native by simply sending HTTP request, which means symbolication
can be more robust (no need to depend on crashed JS to do symbolication) and we can pause JSC to
avoid getting too many redboxes that hide original error.
- reduce the bundle by ~65KB (the size of source-map parsing library we ship, see SourceMap module)

This pull request is a prerequisite to enabling the react-native-windows platform extension.
In the Resolver component, we need to add 'windows' to the list of platforms that are allowed in the DependencyGraph. We also need to add 'react-native-windows' (the name of the Windows platform extension NPM module) to the `providesModuleNodeModules` option. This allows the node_module folder check in the DependencyGraphHelper from node-haste to be bypassed for *.windows.js files in the Windows NPM package.
For good measure, I also included a change to blacklist.js to ensure .windows.js files are ignored when the packager is parameterized on a platform.

This got broken recently. As a result of this, when a module throws while being required, either by regular load or hot reload, the module object is marked as `hasError`. Form that point all subsequent HMR updates will fail because it will think the module failed while executing the factory but the failure could have been on an old run of an old factory.
The fix is very simple: just reset `hasError` to false when accepting a module.

Summary:We found that moving the preloaded modules to the startup section of the RAM Bundle improves TTI quite a bit by saving lots of through the bridge calls and injecting multiple modules at once on JSC. However, doing this on a non hacky way required a lot of work. The main changes this diff does are:
- Add to `BundleBase` additional bundling options. This options are fetched based on the entry file we're building by invoking a module that exports a function (`getBundleOptionsModulePath`).
- Implement `BundleOptions` module to include the `numPreloadedModules` attribute as a bundle additional option. This value is computed by getting the dependencies the entry file has and looking for the first module that exports a module we don't want to preload. The `numPreloadedModules` attribute is then used to decide where to splice the array of modules.
- Additional kung fu to make sure sourcemaps work for both preloaded and non preloaded modules.

Summary:We recently refactor the packager to transform the module names into numeric IDs but we forgot to update the HMR call site. As a consequence, HMR doesn't work the first time a file is saved but the second one.
This is affecting master as of 3/20. If we don't land this before v0.23 is cut we'll have to cherry pick it. This rev does *not* need to be picked on v0.22.

Summary:This adds support for source maps that can be used for “random access modules” / “unbundles”
- source maps contain an extra custom field: `x_facebook_offsets`
- this field maps module IDs to line offsets
- the source map is built as if all files were concatenated
Decoding/symbolication works as follows:
- when decoding a stack trace, and a stack frame comes from a filename that contains only numbers and ends with `.js`, look up the additionally needed line offset in the offset map and add it to the original line of the stack frame.
- consume the source map as usual

Summary:This brings back "Use numeric identifiers when building a bundle", previously backed out.
This version passes on the correct entry module name to code that decides transform options.
Original Description:
Since the combination of node and haste modules (and modules that can be required as both node and haste module) can lead to situations where it’s impossible to decide an unambiguous module identifier, this diff switches all module ids to integers. Each integer maps to an absolute path to a JS file on disk.
We also had a problem, where haste modules outside and inside node_modules could end up with the same module identifier.
This problem has not manifested yet, because the last definition of a module wins. It becomes a problem when writing file-based unbundle modules to disk: the same file might be written to concurrently, leading to invalid code.
Using indexed modules will also help indexed file unbundles, as we can encode module IDs as integers rather than scanning string IDs.

Summary:This rev adds support for production sourcemaps on RAM.
When we inject a module into JSC we use the original `sourceURL` and specify the `startingLineNumber` of the module relative to a "regular" bundle. By doing so, when an error is thrown, JSC will include the provided `sourceURL` as the filename and will use the indicated `startingLineNumber` to figure out on which line the error actually occurred.
To make things a bit simpler and avoid having to deal with columns, we tweak the generated bundle so that each module starts on a new line. Since we cannot assure that each module's code will be on a single line as the minifier might break it on multiple (UglifyJS does so due to a bug on old versions of Chrome), we include on the index the line number that should be used when invoking `JSEvaluateScript`. Since the module length was not being used we replaced the placeholder we have there for the line number.

Summary:Make packager transform files before extracting their dependencies.
This allows us to extract dependencies added by transforms (and to avoid including them manually).
It also allows for better optimization and to get rid of the “whole program optimization” step:
This diff utilizes the new worker introduced in D2976677 / d94a567 – that means that minified builds inline the following variables:
- `__DEV__` → `false`
- `process.env.NODE_ENV` → `'production'`
- `Platform.OS` / `React.Platform.OS` → `'android'` / `'ios'`
and eliminates branches of conditionals with constant conditions. Dependency extraction happens only after that step, which means that production bundles don’t include any modules that are not used.
Fixes#4185

Summary:In order to be able to Hot Load Redux stores and modules that export functions, we need to build infrastructure to bubble up the HMR updates similar to how webpack does: https://webpack.github.io/docs/hot-module-replacement-with-webpack.html.
In here we introduce the minimum of this infrastructure we need to make this work. The Packager server needs to send the inverse dependencies to the HMR runtime that runs on the client so that it can bubble up the patches if they cannot be self accepted by the module that was changed.
This diff relies on https://github.com/facebook/node-haste/pull/40/files which adds support for getting the inverse dependencies.

Summary:**Problem**: As seen in https://github.com/facebook/react-native/issues/5820, many devs are confused by the fact that the offline bundle is not generated when running against the simulator, even when running in the "Release" configuration which is supposed to mimic "production" scenarios.
This pull request is a small change that fixes https://github.com/facebook/react-native/issues/5820 by updating the `react-native-xcode.sh` shell script to still generate the ofline bundle during Release configuration. It also updates `AppDelegate.m` to better document this behaviour in the comments so as to avoid any surprises.
**Test plan**: This is a simple change, the two tests done were
1. In a new React Native project, verify that an offline build is not generated when running against the simulator in "Debug" configuration as per normal.
2. Change to a "Release" configuration via Product > Scheme > Edit Scheme in XCode, then verify that the project runs with the offline build generated.

As spicyj mentioned in commit 6a838a4, the ideal state of affairs when it comes to consuming `react` and `fbjs` from NPM is for the packager not to have knowledge of either package. This PR addresses the `fbjs` part of that, and relies on https://github.com/facebook/fbjs/pull/95. **DO NOT MERGE** until #95 (or a variation) is in `fbjs` and is released to npm.

1. Adds stub modules within RN that expose `fbjs` modules to be required using Haste. After discussing a few ideas with spicyj, this seemed like a good option to keep internal FB devs happy (and not make them change the way they write JS), but allow for removing packager complexity and fit in better with the NPM ecosystem. Note -- it skips stubbing `fetch`, `ExecutionEnvironment`, and `ErrorUtils`, due to the fact that these need to have Native specific implementations, and there's no reason for those implementations to exist in `fbjs`.
2. Removes the modules that were previously being used in lieu of their `fbjs` eq

Summary:
public
The packager currently assumes that all assets that are not JSON or JS files must be images. Although it is possible to add other extension types, they crash the packager if you try to require them, because it attempts to get their dimensions, assuming that they are an image.
This is a crude workaround for that problem, which skips the image-specific processing for non-image assets, but really it would be better if the packager was properly aware of different asset types and treated them differently (e.g. for sounds it could include the duration, for HTML pages it could parse and include linked CSS files, etc).
I've also added an example of using `require('...')` to load a packager-managed HTML page in the UIExplorer WebView example. In future I anticipate that all static asset types (sounds, fonts, etc.) could be handled in this way, which allows them to be edited or added/removed on the fly instead of needing to restart the app.

Summary:
Rather than specifying Babel plugins in the `.babelrc` packaged with react-native, leverage a Babel preset to define the plugins (https://github.com/exponentjs/babel-preset-react-native).
This allows for a much better user experience for those who want (or need) to override options in their project's `.babelrc`.
Prior to this PR, if a user wanted to use a custom babel-plugin (or a custom set of babel plugins), they'd have either 1) manually override the `.babelrc` in the react-packager directory (or fork RN), or 2) specify a custom transformer to use when running the packager that loaded their own `.babelrc`. Note - the custom transformer was necessary because without it, RN's `.babelrc` options would supersede the options defined in the project's `.babelrc`...potentially causing issues with plugin ordering.
This PR makes the transformer check for the existence of a project-level `.babelrc`, and if it it's there, it _doesn't_ use the react-native `.babelrc`. This prevents any oddities with Babel plug

Summary:
Right now, a mock called `debug.js` shadows a node module called `debug`. When I made mocking more strict I didn't realize that it didn't include those mocks any more because requiring `debug` would result in a module like `debug/node.js` which doesn't have a mock associated with it. This diff changes it so it looks at the associated `package.json` to match the name up to mocks. This is the least invasive non-breaking change I can make right now. Yes, mocking strategies are basically fucked but I don't want the haste2 integration to have even more breaking changes right now. Consider this code to be temporary, I'll fix this and make the mocking system more sane mid-term.

Summary:
The feature added in D2862850 only adds the module that requests shallow dependency resolution to the dependencies of a module. The reason why this is happens is because `collect` calls `response.addDependency` but if `recursive` is set to `false`, dependencies don't call `collect` and therefore don't get added to the resolution response. This fixes it by adding dependencies outside of the `collect` call.

The fastfs is intrinsically tied to the dependency graph and the `DependencyGraph` instance is meant to be a base-class for clients anyway. Both in react-packager and jest we are wrapping it with higher-level client specific containers, Resolver and HasteResolver respectively.

`babel-plugin-react-transform` doesn't support to run on transformed code (it doesn't detect some react components). The reason why HMR was originally on the internal transform was so that it worked with non JS code (TypeScript, Coffeescript, etc), but looks like this is not very popupar in the community, maybe because the JS ecosystem is getting better everyday.
So long story short, for now lets move HMR to the external transformer. This should also give us a perf boost.

To make sourcemaps work on Hot Loading work, we'll need to be able to serve them for each module that is dynamically replaced. To do so we introduced a new parameter to the bundler, namely `entryModuleOnly` to decide whether or not to process the full dependency tree or just the module associated to the entry file. Also we need to add `//sourceMappingURL` to the HMR updates so that in case of an error the runtime retrieves the sourcemaps for the file on which an error occurred from the server.
Finally, we need to refactor a bit how we load the HMR updates into JSC. Unfortunately, if the code is eval'ed when an error is thrown, the line and column number are missing. This is a bug/missing feature in JSC. To walkaround the issue we need to eval the code on native. This adds a bit of complexity to HMR as for both platforms we'll have to have a thin module to inject code but I don't see any other alternative. when debugging this is not needed as Chrome supports sourceMappingURLs on eval'ed code

Since the combination of node and haste modules (and modules that can be required as both node and haste module) can lead to situations where it’s impossible to decide an unambiguous module identifier, this diff switches all module ids to integers. Each integer maps to an absolute path to a JS file on disk.
We also had a problem, where haste modules outside and inside node_modules could end up with the same module identifier.
This problem has not manifested yet, because the last definition of a module wins. It becomes a problem when writing file-based unbundle modules to disk: the same file might be written to concurrently, leading to invalid code.
Using indexed modules will also help indexed file unbundles, as we can encode module IDs as integers rather than scanning string IDs.

At the moment we have to disable strict mode for the transform-es2015-modules-commonjs because strict mode leaks to the global scope and breaks the bridge. It was due to the way the polyfills were bundled in the package. To fix it, I wrapped the polyfill modules in an IIFE. Then when strict mode was enabled some polyfills were broken due to strict mode errors so that was fixed too. Also removed the IIFE from the polyfills that included one.
This diff doesn't enable the strict mode transform since some internal facebook modules depend on it not being enabled. When #5214 lands we could make the default babel config shipped with OSS react-native use strict mode modules and facebook could just modify the babel config to disable it if needed.
This will allow removing `"strict": false` from https://github.com/facebook/react-native/blob/master/packager/react-packager/.babelrc#L16Fixes#5316

Summary:
We used to only cache the `dependencies` and `name` of a Module but we were actually accessing two more fields (async dependencies and the `isHaste` field) which meant we were always reading every single file from disk. In D2644383 I noticed that but realized that the Promise was cached, meaning we would read every file once *per instance* and I didn't think about cross-instance reads over time. My initial version added more caching (but also missed the `isHaste` field) but then I got rid of the cache call for `dependencies`. So my change from before didn't make anything worse but it also didn't make anything better. This change now caches everything until the contents of the file actually changes.

Summary:
One consequence we didn't predict after introducing the Internal Transform Pipeline, was that when the workers would get started, we won't require the external transformer the user specified up until the first time each worker received a job. There're 2 visible consequences of this: (1) the transform progress bar seems to get stuck for about 5 seconds the first time the packager receives a request and (2) the first N (# of cores) HMR requests take way longer (about 4 seconds with FB's transformer instead of << 1 second) as we need to require lots of modules.
This diff creates a temporary file for the js transformer workers that requires the user-specified transform file eagerly.
That makes sure workers have imported babel and the transforms before receiving the first request.
There are better ways to do this, like adding an `init()` method to the workers and call that eagerly. I will follow with another diff doing that.

I'm working on deploying haste2 with jest. This updates all the files that require changes for this to work and they are backwards compatible with the current version of jest.
* package.json was just outdated. I think haste1's liberal handling with collisions made this a "non-issue"
* env.js didn't properly set up ErrorUtils, also unsure why that isn't a problem in jest right now already?
* some things were mocking things they shouldn't
* Because of the regex that matches against providesModule and System.import, it isn't possible to list module names more than once. We have multiple tests reusing the same providesModule ids and using System.import with modules that only exist virtually within that test. Splitting up the strings makes the regexes work (we do the same kind of splitting on www sometimes if we need to) and using different providesModule names in different test files fixes the problem. I think the BundlesLayoutIntegration-test is going to be deleted, so this doesn't even matter.

Fixes a terrible bug due to which when Hot Loading enabled when the user reloads we'll serve them the first `hot` bundle he requested. This happened because when HMR enabled we bailed out after sending the HMR updates and didn't rebuild any of the bundles the user requested before. As a consequence, when they reload we'd sent him the first and only one we ever built.
The fix is to tweak the hmr listener to return a promise. This way we can run the remaining code on the file change listener just after the HMR stuff finishes. We need to do it this way to avoid the remaining stuff to compete for CPU with the HMR one and give the best possible experience when HMR is enabled.

We want to support Hot Loading on the packager itself instead of on the transformer. This will allow us to enable it on OSS (and for any scripting language, yay!).
For now to enable Hot Loading the packager's internals transforms need to be manually enabled (start packager with `--enable-internal-transforms`). I think the internal pipeline should always be enabled as it doesn't affect performance if there're no transforms and the user can disable Hot Loading through the setting on the app though. I'll tweak this on a follow up commit.

Before this diff we were only accepting the module that was modified but the user. This works fine as long as the user doesn't modify the dependencies a module has but once he starts doing so the HMR runtime may fail when updating modules' code because they might might a few dependencies. For instance, if the user changes the `src` a `Image` has to reference an image (using the new asset system) that wasn't on the original bundle the user will get a red box. This diff addresses this by diffing the modules the app currently has with the new ones it should have and including all of them on the HMR update. Note this diffing is only done when the we realize the module that was modified changed it's dependencies so there's no additional overhead on this change.

This diff introduces an internal transforms pipeline that integrates with the external one. This has been a feature we've been looking to implement for a long time to use babel instead of `replace` with regexps on many parts of the packager.
Also, to split the bundle we'll need to run one transform. Internally for Facebook we can run the system-import transform altogether withe the other ones. For OSS we offer `transformer.js` which people can use out of the box if they're writing ES6 code. For those people, `transformer.js` will also run the internal transforms`. However they might want to tune the transforms, or even write the code on another language that compiles to Javascript and use a complete different transformer. On those cases we'll need to run the external transforms first and pipe the output through the internal transforms. Note that the order it's important as the internal transforms assume the code is written in JS, though the original code could be on other scripting languages (CoffeeScript, TypeScript, etc).

Summary:
We don't (yet) treat these the same as any other modules because we still have special resolution rules for them in the packager allowing the use of `providesModule`, but I believe this allows people to use npm react in their RN projects and not have duplicate copies of React. Fixesfacebook/react-native#2985.
This relies on fbjs 0.6, which includes `.flow` files alongside the `.js` files to allow them to be typechecked without additional configuration. This also uses react 0.14.5, which shims a couple of files (as `.native.js`) to avoid DOM-specific bits. Once we fix these in React, we will use the same code on web and native. Hopefully we can also remove the packager support I'm adding here for `.native.js`.
This diff is not the desired end state for us – ideally the packager would know nothing of react or fbjs, and we'll get there eventually by not relying on `providesModule` in order to load react and fbjs modules. (fbjs change posted here but not merged yet: https://github.com/facebook/fbjs/pull/84.)
This should also allow relay to work seamlessly with RN, but I haven't verified this.

Summary:

Before this this when a file was changed besides sending the HMR update we rebuild every single bundle that the packager had build (to serve it faster when the user hit cmd+r). Since when hot loading is enabled we don't do cmd+r all this work was pointless (except for when you're developing multiple apps using the same packager instance at the same time, which we can assume is very uncommon). As a consequence, the HMR update was competing with the rebundling job making HMR quite slow (i.e.: on one huge internal app it took up to 6s for the HMR changes to get applied).
So, this diff tweaks the file change listener so that we don't rebundle nor invoke the fileWatchers (use for live reload which is also useless when hot load is enabled) when hot loading is enabled. Also, it makes the HMR listener more high pri than the other listeners so that the HMR dev experience is as good as it can get.

Implement all the necessary glue code for several diffs submitted before to get Hot Loading work end to end:
- Simplify `HMRClient`: we don't need to make it stateful allowing to enable and disable it because both when we enable and disable the interface we need to reload the bundle.
- On the native side we introduced a singleton to process the bundle URL. This new class might alter the url to include the `hot` attribute. I'm not 100% sure this is the best way to implement this but we cannot use `CTLSettings` for this as it's are not available on oss and I didn't want to contaminate `RCTBridge` with something specific to hot loading. Also, we could potentially use this processor for other things in the future. Please let me know if you don't like this approach or you have a better idea :).
- Use this processor to alter the default bundle URL and request a `hot` bundle when hot loading is enabled. Also make sure to enable the HMR interface when the client activates it on the dev menu.
- Add packager `hot` option.
- Include gaeron's `react-transform` on Facebook's JS transformer.
The current implementation couples a bit React Native to this feature because `react-transform-hmr` is required on `InitializeJavaScriptAppEngine`. Ideally, the packager should accept an additional list of requires and include them on the bundle among all their dependencies. Note this is not the same as the option `runBeforeMainModule` as that one only adds a require to the provided module but doesn't include all the dependencies that module amy have that the entry point doesn't. I'll address this in a follow up task to enable asap hot loading (9536142)
I had to remove 2 `.babelrc` files from `react-proxy` and `react-deep-force-update`. There's an internal task for fixing the underlaying issue to avoid doing this horrible hack (t9515889).

Summary:
There's quite a bit of code scattered around the packager regarding ignoring the `providesModule` Haste pragma in any file that isn't in `react-native`, `react-tools` or `parse`. There is even a (passing) test case.
However, there's an edge case.
Take, for example, `fbjs`. It has a module inside of it called `ErrorUtils`. `react-relay` requires this file normally, in Common.JS style, by doing `require('fbjs/libs/ErrorUtils')`. But when `react-native` attempts to require `ErrorUtils` using the HasteModule format (in it's JavaScript initialization), it resolves the `fbjs` `ErrorUtils` module, instead of RN's `ErrorUtils`.
This happens, it turns out, because when a module is read (in `Module._read`), it's not caring about whether or not it should pay attention to `providesModule`, and is just assigning the `providesModule` value as the id of the module no matter what. Then when `Module.getName` is called, it will always use that `data.id` that was set, thus creating the wrong dependency tree.

Summary:
Currently, the app server accepts `transformModulePath` which allows us to use different transformation variants. However, these options persist through the lifetime of the server. So we cannot conditionally transform a module differently for two bundles without restarting the server with different options.
`getTransformOptions` basically allows us to change the options to the transformer at runtime based on the bundle and module being transformed.
These options are also used as a cache key for the transformedSource to ensure that if a file is transformed with different options, caching doesn't cause any inconsistencies.

Hello!
I'm a fan of the *env family of version managers over the *vm family as I find them simpler and less obtrusive, but it seems that they don't currently work so well with react-native on OSX. See #4645
I've made a small addition to the xcode script that resolves the issue for me. Hopefully others will find this useful too :)
If I've not made the right move here, what is the correct way to get react-native projects building in xcode when the binary is not in the $PATH used by the script?
Cheers,

Functions from the path module return paths with the native file system path separator. generateAssetModule is using path.join and path.dirname to generate httpServerLocation. That means that on Windows systems, the generated URL path has backslashes rather than forward slashes which breaks the app's ability to retrieve image assets using require('./image.png'). This change fixes this by checking path.sep and replacing backslashes with slashes on systems that require it.

Summary:

Introduce a new Polyfill module to load bundles. This polyfill contains the function to which System.import gets transformed into. It works similarly to require in the way it's registered. It keeps track of the bundles that have ever been requested using promises, either fulfilled or not. The use of promises makes the implementation quite easy as we don't need to differenciate whether the request has been started or not.
There're a couple of follow up steps that still need to get done:
- Included this polyfill on the ones we automatically include on the bundle.
- Modify the transform to include the modules the user is actually requesting and pipe that through loadBundles so that the promise, once resolved, has the ordered list of modules the user requested.
- Implement the actual native code that loads a bundle. This shouldn't be that taught as native will be able to assume it will never receive the same request twice.

Summary: Extracts the module system from the list of dependencies and adds it back to the bundling process.
Unbundling and Prepack has their own module systems. jest does as well. This is not normally part of the resolver, nor polyfills.
In fact, I think we'll eventually start treating polyfills as normal modules just like core-js.
The prelude is the weird part right now but I think that we'll eventually move the DEV flag to be module level instead of global and we can just get rid of this prelude.

Summary: React Native is a lot more powerful an environment than the browser, so we need an alternate mapping, as specified [here](https://github.com/defunctzombie/node-browser-resolve#browser-field)
An example:
```js
{
"browser": {
"./lib/server": false
},
"react-native": {
"dgram": "react-native-udp",
"fs": "react-native-level-fs"
},
"chromeapp": {
"dgram": "chrome-dgram",
"fs": "level-filesystem"
}
}
```
on the other hand, if "react-native" is not present in package.json, you should fall back to "browser"
other than the one (nesting) test added, the tests are unchanged, just done for both "react-native" and "browser"
(I've implemented [react-native-udp](https://npmjs.org/package/react-native-udp) and [react-native-level-fs](https://npmjs.org/package/react-native-level-fs), but they obviously don't belong in the traditional "browser" field as they won't run anywhere except in React Native.)

Summary: This adds a build option for using Prepack (an experimental packager) to
build a bundle. It doesn't actually take on the npm package dependency
because it's not published/open source (yet).
This will be used while we experiment and should be maintained as the
build system changes so that we can continue getting fresh builds.
I found that saveBundleAndMap and processBundle were over abstracted and
got in my way so I inlined it and removed the unit tests because the unit
test was testing trivial code that is likely to change interface.
I went with a separate build phase and a separate Bundle class even though
there are a lot of commonalities. I imagine that the requirements for
Prepack will continue to diverge. Especially for source maps but a larger
refactor could try to unify these a bit more. The fact that modules are
wrapped before the write phase seems to be an unfortunate architecture
that makes this difficult.

Before the update to React 0.14, we were pulling `performanceNow` from a hardcoded `react-tools` version (b4e74e38e4/src/shared/vendor/performance/performanceNow.js), so we couldn't just fix the file and had to special case it.

Summary: I'm planning to split up `DependencyResolver` into the react-native specific implementation of it and a new, generic resolver that is going to replace `node-haste` for jest and other places where we might need JS dependency resolution.
The plan is to split the two folders up so that:
* `Resolver` is the folder for all the react-native specific resolver code
* `DependencyResolver` will become a standalone library, eventually moving into a package called `node-haste`.
There is still a lot to be figured out. This is just the first diff of likely many. The current goal is to make `DependencyResolver` standalone to be able to create an instance of a resolver and resolve all dependencies for a file. This is when I can start integrating it more seriously with jest.
This diff simply moves a bunch of things around and turns `HasteModuleResolver` into an ES2015 class ( :) ).
