# Contributing to Pinafore
|
|
|
|
## Installing
|
|
|
|
To install with dev dependencies, run:
|
|
|
|
yarn
|
|
|
|
## Dev server
|
|
|
|
To run a dev server with hot reloading:
|
|
|
|
yarn run dev
|
|
|
|
Now it's running at `localhost:4002`.
|
|
|
|
**Linux users:** for file changes to work,
|
|
you'll probably want to run `export CHOKIDAR_USEPOLLING=1`
|
|
because of [this issue](https://github.com/paulmillr/chokidar/issues/237).
|
|
|
|
## Linting
|
|
|
|
Pinafore uses [JavaScript Standard Style](https://standardjs.com/).
|
|
|
|
Lint:
|
|
|
|
yarn run lint
|
|
|
|
Automatically fix most linting issues:
|
|
|
|
yarn run lint-fix
|
|
|
|
## Integration tests
|
|
|
|
Integration tests use [TestCafé](https://devexpress.github.io/testcafe/) and a live local Mastodon instance
|
|
running on `localhost:3000`.
|
|
|
|
### Running integration tests
|
|
|
|
The integration tests require running Mastodon itself,
|
|
meaning the [Mastodon development guide](https://docs.joinmastodon.org/dev/setup/)
|
|
is relevant here. In particular, you'll need a recent
|
|
version of Ruby, Redis, and Postgres running. For a full list of deps, see `bin/setup-mastodon-in-travis.sh`.
|
|
|
|
Run integration tests, using headless Chrome by default:
|
|
|
|
npm test
|
|
|
|
Run tests for a particular browser:
|
|
|
|
BROWSER=chrome yarn run test-browser
|
|
BROWSER=chrome:headless yarn run test-browser
|
|
BROWSER=firefox yarn run test-browser
|
|
BROWSER=firefox:headless yarn run test-browser
|
|
BROWSER=safari yarn run test-browser
|
|
BROWSER=edge yarn run test-browser
|
|
|
|
If the script isn't able to set up the Postgres database, try running:
|
|
|
|
sudo su - postgres
|
|
|
|
Then:
|
|
|
|
psql -d template1 -c "CREATE USER pinafore WITH PASSWORD 'pinafore' CREATEDB;"
|
|
|
|
### Testing in development mode
|
|
|
|
In separate terminals:
|
|
|
|
1\. Run a Mastodon dev server:
|
|
|
|
yarn run run-mastodon
|
|
|
|
2\. Run a Pinafore dev server:
|
|
|
|
yarn run dev
|
|
|
|
3\. Run a debuggable TestCafé instance:
|
|
|
|
npx testcafe --debug-mode chrome tests/spec
|
|
|
|
### Test conventions
|
|
|
|
The tests have a naming convention:
|
|
|
|
* `0xx-test-name.js`: tests that don't modify the Mastodon database (read-only)
|
|
* `1xx-test-name.js`: tests that do modify the Mastodon database (read-write)
|
|
|
|
In principle the `0-` tests don't have to worry about
|
|
clobbering each other, whereas the `1-` ones do.
|
|
|
|
### Mastodon used for testing
|
|
|
|
There are two parts to the Mastodon data used for testing:
|
|
|
|
1. A Postgres dump and a tgz containing the media files, located in `fixtures`
|
|
2. A script that populates the Mastodon backend with test data (`restore-mastodon-data.js`).
|
|
|
|
The reason we don't use a Postgres dump for everything
|
|
is that Mastodon will ignore changes made after a certain period of time, and we
|
|
don't want our tests to randomly start breaking one day. Running the script ensures that statuses,
|
|
favorites, boosts, etc. are all "fresh".
|
|
|
|
### Updating the test data
|
|
|
|
You probably don't want to do this, as the `0xx` tests are pretty rigidly defined against the test data.
|
|
Write a `1xx` test instead and insert what you need on-the-fly.
|
|
|
|
If you really need to, though, you can either:
|
|
|
|
1. Add new test data to `mastodon-data.js`
|
|
|
|
or
|
|
|
|
1. Comment out `await restoreMastodonData()` in `run-mastodon.js`
|
|
2. Make your changes manually to the live Mastodon
|
|
3. Run the steps in the next section to back it up to `fixtures/`
|
|
|
|
### Updating the Mastodon version
|
|
|
|
1. Run `rm -fr mastodon` to clear out all Mastodon data
|
|
1. Comment out `await restoreMastodonData()` in `run-mastodon.js` to avoid actually populating the database with statuses/favorites/etc.
|
|
2. Update the `GIT_TAG` in `mastodon-config.js` to whatever you want
|
|
3. If the Ruby version changed (check Mastodon's `.ruby-version`), install it and update `RUBY_VERSION` in `mastodon-config.js` as well as the Ruby version in `.github/workflows`.
|
|
4. Run `yarn run-mastodon`
|
|
5. Run `yarn backup-mastodon-data` to overwrite the data in `fixtures/`
|
|
6. Uncomment `await restoreMastodonData()` in `run-mastodon.js`
|
|
7. Commit all changed files
|
|
8. Run `rm -fr mastodon/` and `yarn run run-mastodon` to confirm everything's working
|
|
|
|
Check `mastodon.log` if you have any issues.
|
|
|
|
Note that we also run `db:migrate` just to play it safe, but
|
|
updating the `fixtures/` should make that a no-op.
|
|
|
|
## Unit tests
|
|
|
|
There are also some unit tests that run in Node using Mocha. You can find them in `tests/unit` and
|
|
run them using `yarn run test-unit`.
|
|
|
|
## Debug build
|
|
|
|
To disable minification in a production build (for debugging purposes), you can run:
|
|
|
|
DEBUG=1 yarn build
|
|
|
|
## Debugging Webpack
|
|
|
|
The Webpack Bundle Analyzer `report.html` and `stats.json` are available publicly via e.g.:
|
|
|
|
- [dev.pinafore.social/report.html](https://dev.pinafore.social/report.html)
|
|
- [dev.pinafore.social/stats.json](https://dev.pinafore.social/stats.json)
|
|
|
|
This is also available locally after `yarn run build` at `.sapper/client/report.html`.
|
|
|
|
## Deploying
|
|
|
|
This section only applies to `dev.pinafore.social` and `pinafore.social`, not if you're hosting your own version of
|
|
Pinafore.
|
|
|
|
The site uses [Vercel](https://vercel.com). The `master` branch publishes to `dev.pinafore.social` and the `production`
|
|
branch deploys to `pinafore.social`.
