Summary:
The use of `tee /dev/stderr` failed when running as a child process
under Node for some reason. (I haven’t been able to figure out why—it
works fine when run as a standalone script or when run as a child
process under Python.) This is also technically Linux-specific, so I’ve
changed it to use a process substitution. After looking around for a
bit, there doesn’t seem to be a way to do this in a way that is
portable, uses only POSIX shell features, and doesn’t create temporary
files all at the same time, so the script is now run under `bash`.
Test Plan:
Run `yarn travis` and note that the `ensure-flow.sh` output no longer
contains the line `tee: /dev/stderr: No such device or address`.

Summary:
Placing `STOPSHIP` or `stopship` (or any case variant) in any file
tracked by Git will now cause a `yarn travis` failure. If you need to
use this string, you can concatenate it as `"stop" + "ship"` or
equivalent.
Test Plan:
In `travis.js`, change `"check-stop" + "ships"` to `"check-stopships"`,
and note that this causes the build to fail with a nice message. Note
that this also causes `check-stopships.sh` to fail even when invoked
from an unrelated directory, like `src`.

Summary:
This fixes two problems in the previous version:
- A new JS file not checked into git, but with a `@flow` directive,
would cause `ensure-flow` to fail, because one list of files was
from `git grep` and the other was from `find`.
- Only the hard-coded directories `src config scripts` were searched.
Now, we search all JS files checked into Git, except for some hard-coded
exceptions, namely `flow-typed`.
Test Plan:
1. Add `foo.js`, not checked into Git. Note that `ensure-flow` passes.
2. Add `@flow` to `foo.js`, and note that `ensure-flow` still passes.
3. Remove `@flow` from `.eslintrc.js`, and note that `ensure-flow`
fails and nicely prints the filename. (Note: this file is at the
repository root.)
4. Create a file `echo stuff >$'naughty\nfilename.js'`, and note that
`ensure-flow` has the correct behavior in both positive and
negative cases.

Summary:
This way, our frontend can talk to a backend that can read from the
filesystem (among other things).
Paired with @decentralion.
Test Plan:
```
$ yarn backend
$ SOURCECRED_DIRECTORY=/tmp/srccrd yarn start
$ # verify that the browser looks good
$ mkdir /tmp/srccrd
$ echo hello >/tmp/srccrd/world
$ curl localhost:3000/api/v1/data/world
hello
$ curl localhost:4000/api/v1/data/world
hello
```

Summary:
- The value of `process.stdout.isTTY` is either `true` or `undefined`.
Flow (reasonably) dislikes this, so we add an explicit check.
- More `package.json` burnination.
Test Plan:
Note that `require("./package.json").proxy === undefined` in the Node
console, and that `yarn start` works.
wchargin-branch: flow--scripts-start
- scripts/backend.js: We incorrectly set an environment variable to
a boolean, when in fact it must be a string. Fixed it to set a string
value "true", and updated usage in config/babel.js
- scripts/test.js: No changes
- scripts/build.js: Removed a call to printHostingInstructions, so that
we don't need to require the package.json.
Test plan:
`yarn travis --full` passes, and the SourceCred cli still works.
This script ensures that either //@flow or //@no-flow is present in
every js file. Every existing js file that would fail this check has
been given //@no-flow, we should work to remove all of these in the
future.
Test plan:
I verified that `yarn travis` fails before fixing the other js files,
and passes afterwards.
Summary:
Consequently, Babel won’t transform classes to their roughly equivalent
ES5 counterparts, etc.
Test Plan:
Create `src/classy.js` with `class X {}; console.log(X);`. Then, add a
build target for `classy: resolveApp("src/classy.js"),` in `paths.js`.
Use `yarn backend` and inspect the contents of `bin/classy.js`; in
particular, look at the definition of `X` (whatever the argument to
`console.log` is). Before this commit, the result will be a big
complicated mess. After this commit, it will be `class X {}`.
Note also that `yarn travis --full` passes, indicating that the two
manual tests, which call out to the utilities in `bin/`, still work.

Summary:
Running `yarn backend` will now bundle backend applications. They’ll be
placed into the new `bin/` directory. This enables us to use ES6 modules
with the standard syntax, Flow types, and all the other goodies that
we’ve come to expect. A backend build takes about 2.5s on my laptop.
Created by forking the prod configuration to a backend configuration and
trimming it down appropriately.
To test out the new changes, this commit changes `fetchGitHubRepo` and
its driver to use the ES6 module system and Flow types, both of which
are properly resolved.
Test Plan:
Run `yarn backend`. Then, you can directly run an entry point via
```
$ node bin/fetchAndPrintGitHubRepo.js sourcecred example-repo "${TOKEN}"
```
or invoke the standard test driver via
```shell
$ GITHUB_TOKEN="${TOKEN}" src/backend/fetchGitHubRepoTest.sh
```
where `${TOKEN}` is your GitHub authentication token.

Reorganize the code so that we have a single package.json file, which is at the root.
All source code now lives under `src`, separated into `src/backend` and `src/explorer`.
Test plan:
- run `yarn start` - it works
- run `yarn test` - it finds the tests (all in src/explorer) and they pass
- run `yarn flow` - it works. (tested with an error, that works too)
- run `yarn prettify` - it finds all the js files and writes to them
