Making Pull Requests

When making a pull request, add a changeset which helps with releases.

yarn changeset

This will prompt you asking what type of change was made.

Releases

For those contributors that have access to publish to npm, the following is how you do releases.

From the main branch do a pull, install and build:

git pull origin main
yarn install
yarn build

Then bump the versions:

yarn changeset version

This should change package.json bumping version numbers and update changelogs. Inspect these to make sure they are what you expect.

Commit and push these changes, then run an npm publish for each of the packages that have changed.

Important! Ordering publishes can be important. If @astrojs/parser changes you should publish that before astro, for example.

cd packages/astro
npm publish

Running benchmarks

We have benchmarks to keep performance under control. You can run these by running (from the project root):

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:

node test/benchmark/build.bench.js --save
node test/benchmark/dev.bench.js --save

Which will update the build and dev benchmarks.
