The webpack process took quite a while to run, and there were no updates in the console while running.
This PR adds a spinner (when there is no dashboard) and status updates every 5 seconds. When there is a dashboard, the updates are added to a new line.
After (with dashboard):

PR feedback and consistency changes
Changed the constructor signature to accept an options object instead of individual optional parameters, for readability.
Changed library_manager to use the spinner when not using the dashboard, for consistency’s sake. Additionally increased the update time for the library manager from 750ms to 1s.
Fix lint errors
Added `"variable-name": ["allow-leading-underscore”]` to `tslint.json` due to a lack of the ability to prefix backing variables with underscore. This is an [ongoing discussion](https://github.com/palantir/tslint/issues/1489), and something the community thinks should be implemented, as it the preferred way to use a property with backing variable in TypeScript.
When adding URLs to IPFS CORS that are not localhost, the IPFS daemon needed to be restarted after non-localhost CORS updates were added to the IPFS config. Without the restart, any non-localhost URLs added to the CORS were not being sent in the CORS header.
After this change, when the IPFS process is run, the following happens:
1. IPFS config is checked if the correct CORS settings are present in the config.
2. If not present, they are updated and IPFS is restarted.
3. If they are present, continue without restarting IPFS.
This commit introduces two new plugin APIs `registerTestContractFactory()` and
`registerCustomContractGenerator()`, which can be used to register a factory function
for the creation of web3 contract instances within tests, and custom code generation
for `embark console` respectively.
Example:
```
// some.plugin.js
module.exports = function (embark) {
embark.registerTestContractFactory(function (contractRecipe, web3) {
// do something with web3 and contractRecipe and return contract instance here
});
};
```
**Notice that**:
- This factory function is used for contract instance creation within tests.
A `contractRecipe` and a `web3` instance is accessible within the factory.
Example:
```
// some.plugin.js
module.exports = function (embark) {
embark.registerCustomContractGenerator(function (contractRecipe) {
// returns code string that will be eval'ed
});
};
```
**Notice that**:
- Once registered, this generator will be used for **all** contract instances
that will be created for `embark console`, including built-in once like
ENSRegistry.
- While this does affect contract creation in client-side code, it doesn't
actually affect the instances created for deployment hooks **if** deployment
hooks are written as functions.
Closes#1066
Always use custom generator and fallback to vanilla
Include yarn's global path when modifying `NODE_PATH` since dependencies are
deduped when a package is installed globally with yarn, which is different from
npm's behavior.
Fix webpack resolution by listing relative `'node_modules'` in
`resolve/Loader:{modules:[...]}`. This ensures that dependecies' dependecies
are resolved correctly when webpack builds a DApp.
Remove the invocation of `.catch()` on a subscription object which lacks that
method.
**TL;DR**
These changes affect workflow with yarn. To prevent embark's `prepare` script
from running undesirably:
- If node_modules is in place and you're reinstalling after switching branches:
```
yarn run install_all
```
- If node_modules is missing (fresh clone or deleted):
```
EMBARK_NO_PREPARE=t yarn install && yarn run install_all
```
It's not recommended to set `EMBARK_NO_PREPARE` in your environment (e.g. in
`.bashrc`) since that would interfere with embark's `release` script if/when
you run it.
-----------------
**1.** Specify embark's build-related steps in the `prepare` script of
package.json.
When embark is installed directly from GitHub the `prepare` script results in a
"pre install" phase (handled automatically by npm/yarn) that fetches
devDependencies, builds embark (including embark-ui), packs a tarball with the
same steps (minus testing and tree-checking) as would happen during an embark
release, and finally does a production install from that tarball.
Important point: installs from GitHub must be performed with yarn; they're no
longer possible with npm since during the "pre install" phase npm will honor
embark's `.npmrc` and `"engines"` settings.
The following will work correctly after this commit is merged:
```
yarn [global] add git+https://github.com/embark-framework/embark.git
```
Use of "hosted git" shortcuts (e.g. `embark-framework/embark#bracnh`) won't
work correctly because yarn doesn't fully support them. See:
https://github.com/yarnpkg/yarn/issues/5235.
It's important to use `git+https` urls. Following a succesful install with
`git+https` it is possible to use a "hosted git" shortcut or `https` url, but
that's owing to a subtle and unreliable interaction between yarn's cache and
yarn's logic for installing from a url/shortcut.
**2.** Adjust the npm configs (`.npmrc`) for embark/-ui so that `yarn run [cmd]
[--opt]` can be used in place of `npm run [cmd] -- [--opt]`.
Either way is okay for running scripts, they're equivalent, but note the
requirement to use `--` before specifying command options with `npm run`.
**3.** Introduce yarn configs (`.yarnrc`) for embark/-ui and include the
`check-files` directive.
H/t to @alaibe for the recommendation.
**4.** Ignore embark's `dist/typings` and `scripts` directories when packing a
tarball.
**5.** Refactor embark/-ui's npm-scripts in relation to the `prepare` script,
and make other small improvements.
Notably, if the environment variable `EMBARK_NO_PREPARE` is truthy (from JS
perspective) then embark's `prepare` script will exit early. This prevents
`install_all` and `prepare` from getting stuck in a loop (`install:core` uses
cross-env to set `EMBARK_NO_PREPARE`) and provides a mechanism for users to
skip the `prepare` script when doing a fresh install:
```
EMBARK_NO_PREPARE=t yarn install
```
**6.** Give `.js` extensions to node scripts in embark's `scripts/`, remove the
shebang lines, and have npm-scripts explicitly invoke them with node.
This arrangement works for all platforms: Linux, macOS, and Windows.
**7.** Adjust travis and appveyor configs.
Since at present there aren't any tests or other CI steps that make use of
embark-ui's production build, set `EMBARK_NO_PREPARE` in the CI environments
and invoke `build:node` directly.
Check the working tree after `yarn install` for embark/-ui. This detects
situations where changes should have been committed to `yarn.lock` but were
not. Check the working tree again at the end to detect situations where ignore
files should have been adjusted but were not. Both checks could also detect
other surprising behavior that needs to be investigated. Any time the working
tree is not clean (there are untracked files or changes) CI will fail.
Drop CI runs for node 8.11.3 because that version ships with an older npm that
results in unstaged changes to the test apps' `package-lock.json` files,
causing the working tree check to fail at the end of the CI run. A simple
workaround isn't apparent, but the matter can be revisited.
**8.** Refactor embark's `release` script in light of the `prepare` script.
Notably, do the push step only after `npm publish` completes successfully. This
allows embark's `prepare` and `prepublishOnly` scripts to detect problems
before a commit and tag are pushed to GitHub, avoiding a need to rebase/revert
the remote release branch; the local branch will still need to have a commit
dropped and tag deleted before rerunning the `release` script.
Prompt the user if the `release` script is not being run in `--dry-run` mode.
Provide additional visual indicators of `--dry-run` mode.
Force the user to supply `--repo-branch [branch]` if the intention is to
release from a branch other than `master`.
Ignore the sequence of bytes `03:ef:bf:bd` that are sent between
Chrome/Firefox (others?) and the node process when a browser connected via
websocket to the blockchain proxy is closed/reloaded. The theory is that
sequence is part of a socket control frame that is leaking to `parseJsonMaybe`
from `http-proxy-middleware`.
Use proper stream parsing to consistently track JSON-RPC messages.
For HTTP POST requests use the `stream-json` package to assemble request and
response message objects.
For WebSocket requests continue to use `simples/lib/parsers/ws` to process
stream frames into messages. For Websocket responses use the Receiver class of
the `ws` package to process stream data into messages. In both cases, make use
of the `cloneable-readable` and `stream-chain` packages to avoid leaks.
This mishmash of stream parsing approaches is the result of much
experimentation to find a working solution. For example,
`simples/lib/parsers/ws` does't work for processing WebSocket responses and
`ws.Receiver` doesn't work for processing requests. Additional revisions may be
necessary.
Revise `blockchain_process/dev_funds.js` to use web3's HTTP provider if a DApp
disables the WebSocket proxy.
As discussed in #1121, the `eject-webpack` command in Embark's CLI
exposes implementation details of the CLI's build process, namely webpack.
If we ever change our internal build tooling, commands like this
will become obsolete immediately. That's why this commit introduces
a new command `eject-build-config`, with `eject-webpack` being an alias for it.
So the following commands are the same:
```
$ embark eject-build-config
```
and
```
$ embark eject-webpack
```
The `eject-webpack` command can now be marked as deprecated and removed in future
versions of Embark.
Closes#1121
This commit allows dapp developers to specify an ABI for contracts that are
already deployed and which source they don't own.
Prior to this commit there were two options to use web3 contract instances of 3rd
party contracts in Embark:
1. Define an interface for the 3rd party contract and have Embark compile that
2. Define path to source file of 3rd party contract and have Embark compile that
Both options result in Embark getting hold of the contracts ABI so it can be used
by web3 to create instances.
Now there's a third option that doesn't require creating an interface, nor the
source of the 3rd party contract.
Example:
```
// config/contracts.js
...
contracts: {
SimpleStorage: {
address: '0x0bFb07f9144729EEF54A9057Af0Fcf87aC7Cbba9',
abiDefinition: [...] // full ABI
}
},
afterDeploy: async(deps) => {
const simpleStorage = deps.contracts.SimpleStorage;
const value = await simpleStorage.methods.get().call();
console.log('value', value);
}
```
