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.
