# Contributor Manual
|
|
|
|
We welcome contributions of any size and skill level. As an open source project, we believe in giving back to our contributors and are happy to help with guidance on PRs, technical writing, and turning any feature idea into a reality.
|
|
|
|
## Prerequisite
|
|
|
|
```shell
|
|
node: "^12.20.0 || ^14.13.1 || >=16.0.0"
|
|
yarn: "^1.22.10"
|
|
# otherwise, your build will fail
|
|
```
|
|
|
|
## Setting up your local repo
|
|
|
|
Astro uses yarn workspaces, so you should **always run `yarn install` from the top-level project directory.** running `yarn install` in the top-level project root will install dependencies for `astro`, `www`, `docs`, and every package in the repo.
|
|
|
|
```shell
|
|
git clone && cd ...
|
|
yarn install
|
|
yarn build:all
|
|
```
|
|
|
|
## Development
|
|
|
|
```shell
|
|
# starts a file-watching, live-reloading dev script for active development
|
|
yarn dev
|
|
# build the entire project, one time.
|
|
yarn build
|
|
```
|
|
|
|
## Running tests
|
|
|
|
```shell
|
|
# run this in the top-level project root to run all tests
|
|
yarn test
|
|
# run only a few tests, great for working on a single feature
|
|
# (example - `yarn test rss` runs `astro-rss.test.js` tests)
|
|
yarn test $STRING_MATCH
|
|
```
|
|
|
|
## Other useful commands
|
|
|
|
```shell
|
|
# auto-format the entire project
|
|
# (optional - a GitHub Action formats every commit after a PR is merged)
|
|
yarn format
|
|
```
|
|
|
|
```shell
|
|
# lint the project
|
|
# (optional - our linter creates helpful warnings, but not errors.)
|
|
yarn lint
|
|
```
|
|
|
|
## Making a Pull Request
|
|
|
|
When making a pull request, be sure to add a changeset when something has changed with Astro. Non-packages (`examples/*`, `docs/*`, and `www/*`) do not need changesets.
|
|
|
|
```shell
|
|
yarn changeset
|
|
```
|
|
|
|
## Running benchmarks
|
|
|
|
We have benchmarks to keep performance under control. You can run these by running (from the project root):
|
|
|
|
```shell
|
|
yarn workspace astro run benchmark
|
|
```
|
|
|
|
Which will fail if the performance has regressed by **10%** or more.
|
|
|
|
To update the times cd into the `packages/astro` folder and run the following:
|
|
|
|
```shell
|
|
node test/benchmark/build.bench.js --save
|
|
node test/benchmark/dev.bench.js --save
|
|
```
|
|
|
|
Which will update the build and dev benchmarks.
|
|
|
|
# Releasing Astro
|
|
|
|
_Note: Only priviledged contributors (L3+) can release new versions of Astro._
|
|
|
|
The repo is set up with automatic releases, using the changeset GitHub action & bot.
|
|
|
|
To release a new version of Astro, find the `Version Packages` PR, read it over, and merge it.
|
|
|
|
## Releasing PR preview snapshots
|
|
|
|
Our release tool `changeset` has a feature for releasing "snapshot" releases from a PR or custom branch. These are npm package publishes that live temporarily, so that you can give users a way to test a PR before merging. This can be a great way to get early user feedback while still in the PR review process.
|
|
|
|
To release a snapshot, run the following locally:
|
|
|
|
```shell
|
|
# Note: XXX should be a keyword to identify this release. Ex: `--snapshot routing` & `--tag next--routing`
|
|
|
|
# 1:
|
|
yarn changeset version --snapshot XXX
|
|
# 2: (Manual) review the diff, and make sure that you're not releasing more than you need to.
|
|
git checkout -- examples/ docs/ www/
|
|
# 3:
|
|
yarn release --tag next--XXX
|
|
# 4: (Manual) review the publish, and if you're happy then you can throw out all local changes
|
|
git reset --hard
|
|
```
|
|
|
|

|
|
|
|
## Releasing `astro@next` (aka "prerelease mode")
|
|
|
|
Sometimes, the repo will enter into "prerelease mode". In prerelease mode, our normal release process will publish npm versions under the `next` dist-tag, instead of the default `latest` tag. We do this from time-to-time to test large features before sharing them with the larger Astro audience.
|
|
|
|
While in prerelease mode, follow the normal release process to release `astro@next` instead of `astro@latest`. To release `astro@latest` instead, see [Releasing `astro@latest` while in prerelease mode](#user-content-releasing-astrolatest-while-in-prerelease-mode).
|
|
|
|
Full documentation: https://github.com/atlassian/changesets/blob/main/docs/prereleases.md
|
|
|
|
### Entering prerelease mode
|
|
|
|
If you have gotten permission from the core contributors, you can enter into prerelease mode by following the following steps:
|
|
|
|
- Run: `yarn changeset pre enter next` in the project root
|
|
- Create a new PR from the changes created by this command
|
|
- Review, approve, and more the PR to enter prerelease mode.
|
|
- If successful, The "Version Packages" PR (if one exists) will now say "Version Packages (next)".
|
|
|
|
### Exiting prerelease mode
|
|
|
|
Exiting prerelease mode should happen once an experimental release is ready to go from `npm install astro@next` to `npm install astro`. Only a core contributor run these steps. These steps should be run before
|
|
|
|
- Run: `yarn changeset pre exit` in the project root
|
|
- Create a new PR from the changes created by this command.
|
|
- Review, approve, and more the PR to enter prerelease mode.
|
|
- If successful, The "Version Packages (next)" PR (if one exists) will now say "Version Packages".
|
|
|
|
### Releasing `astro@latest` while in prerelease mode
|
|
|
|
When in prerelease mode, the automatic PR release process will no longer release `astro@latest`, and will instead release `astro@next`. That means that releasing to `latest` becomes a manual process. To release latest manually while in prerelease mode:
|
|
|
|
1. _In the code snippets below, replace `0.X` with your version (ex: `0.18`, `release/0.18`, etc.)._
|
|
1. Create a new `release/0.X` branch, if none exists.
|
|
1. Point `release/0.X` to the latest commit for the `v0.X` version.
|
|
1. `git cherry-pick` commits from `main`, as needed.
|
|
1. Make sure that all changesets for the new release are included. You can create some manually (via `yarn changeset`) if needed.
|
|
1. Run `yarn changeset version` to create your new release.
|
|
1. Run `yarn release` to publish your new release.
|
|
1. Run `git push && git push --tags` to push your new release to GitHub.
|
|
1. Run `git push release/0.X:latest` to push your release branch to `latest`. This will trigger an update to the docs site, the www site, etc.
|
|
1. Go to https://github.com/snowpackjs/astro/releases/new and create a new release. Copy the new changelog entry from https://github.com/snowpackjs/astro/blob/latest/packages/astro/CHANGELOG.md.
|
|
1. Post in Discord #announcements channel, if needed!

# Translations
|
|
|
|
Help us translate [docs.astro.build](https://docs.astro.build/) into as many languages as possible! This can be a great way to get involved with open source development without having to code.
|
|
|
|
Our translation process is loosely based off of [MDN.](https://hacks.mozilla.org/2020/12/an-update-on-mdn-web-docs-localization-strategy/)
|
|
|
|
### Important: Beta Status
|
|
|
|
Astro is changing quickly, and so are the docs. We cannot translate too many pages until Astro is closer to a v1.0.0 release candidate. **To start, do not translate more than the "getting started" page.** Once we are closer to a v1.0.0 release candidate, we will begin translating all pages.
|
|
|
|
### Tier 1: Priority Languages
|
|
|
|
**Tier 1** languages are considered a top priority for Astro documentation. The docs site should be fully translated into these languages, and reasonably kept up-to-date:
|
|
|
|
- Simplified Chinese (zh-CN)
|
|
- Traditional Chinese (zh-TW)
|
|
- French (fr)
|
|
- Japanese (ja)
|
|
|
|
We are always looking for people to help us with these translations. If you are interested in getting involved, please [reach out to us](https://astro.build/chat) on Discord in the `i18n` channel.
|
|
|
|
### Tier 2 Languages
|
|
|
|
All other languages are considered **Tier 2**. Tier 2 language translations are driven by the community, with support from core maintainers. If you want to see the Astro docs site translated into a new language, then we need your help to kick off the project!
