All Remix development happens here on GitHub. There are two main branches in this repository that you should be aware of:
main
- This is the stable line. Code in this branch should always pass all the tests. Hot fixes may be pushed directly to this branch without appearing indev
. Docs on the website reflect this branch.dev
- This is where most development happens. When hot fix commits land inmain
they are merged into this branch. Feature branches are based on this branch and are merged in as they are completed.
We currently use pnpm to develop Remix.
# install everything
pnpm install
# run the build
pnpm build
# run the unit tests
pnpm test:primary
# run the unit tests for a specific package in watch mode
pnpm test:primary packages/remix-react --watch
# run the playwright integration tests in Chromium
pnpm test:integration --project chromium
# run specific playwright integration tests in Chromium
pnpm test:integration integration/client-data --project chromium
New releases should be created from release branches originating from the dev
branch. When you are ready to begin the release process:
- Make sure you've pulled all of the changes from GitHub for both
dev
andmain
branches - Check out the
dev
branch - If needed, bump the dependencies to the correct React Router release
./scripts/bump-router-versions.sh [pre|latest]
- Create a new release branch with the
release-
prefixgit checkout -b release-next
- IMPORTANT: The
release-
prefix is important, as this is what triggers our GitHub CI workflow that will ultimately publish the release
- Merge
main
into the release branch
Changesets will do most of the heavy lifting for our releases. When changes are made to the codebase, an accompanying changeset file should be included to document the change. Those files will dictate how Changesets will version our packages and what shows up in the changelogs.
- Ensure you are on the new
release-*
branch - Enter Changesets pre-release mode using the
pre
tag:pnpm changeset pre enter pre
- Commit the change and push the
release-*
branch to GitHub - Wait for the release workflow to finish - the Changesets action in the workflow will open a PR that will increment all versions and generate the changelogs
- Review the updated
CHANGELOG
files and make any adjustments necessary, then merge the PR into therelease-*
branchfind packages -name 'CHANGELOG.md' -mindepth 2 -maxdepth 2 -exec code {} \;
- Once the PR is merged, the release workflow will publish the updated packages to npm
- At this point, you can begin crafting the release notes for the eventual stable release in the root
CHANGELOG.md
file in the repo- Copy the template for a new release and update the version numbers and links accordingly
- Copy the relevant changelog entries from all packages into the release notes and adjust accordingly
- Commit these changes directly to the
release-*
branch - they will not trigger a new prerelease since they do not include a changeset
You may need to make changes to a pre-release prior to publishing a final stable release. To do so:
- Make whatever changes you need
- Create a new changeset:
pnpm changeset
- IMPORTANT: This is required even if you ultimately don't want to include these changes in the logs
- Remember, changelogs can be edited prior to publishing, but the Changeset version script needs to see new changesets in order to create a new version
- Commit the changesets and push the
release-*
branch to GitHub - Wait for the release workflow to finish and the Changesets action to open its PR that will increment all versions
- Review the PR, make any adjustments necessary, and merge it into the
release-*
branch - Once the PR is merged, the release workflow will publish the updated packages to npm
- Make sure you copy over the new changeset contents into stable release notes in the root
CHANGELOG.md
file in the repo
- Exit Changesets pre-release mode:
pnpm changeset pre exit
- Commit the edited
pre.json
file along with any unpublished changesets, and push therelease-*
branch to GitHub - Wait for the release workflow to finish - the Changesets action in the workflow will open a PR that will increment all versions and generate the changelogs for the stable release
- Review the updated
CHANGELOG
files and make any adjustments necessaryfind packages -name 'CHANGELOG.md' -mindepth 2 -maxdepth 2 -exec code {} \;
- Our automated release process should have removed prerelease entries
- Finalize the release notes
- This should already be in pretty good shape in the root
CHANGELOG.md
file in the repo - Do a quick double check that all iterated prerelease changesets got copied over
- This should already be in pretty good shape in the root
- Merge the PR into the
release-*
branch - Once the PR is merged, the release workflow will publish the updated packages to npm
- Once the release is published:
- Pull the latest
release-*
branch containing the PR you just merged - Merge the
release-*
branch intomain
using a non-fast-forward merge and push it up to GitHubgit checkout main; git merge --no-ff release-next
- Merge the
release-*
branch intodev
using a non-fast-forward merge and push it up to GitHubgit checkout dev; git merge --no-ff release-next
- Convert the
remix@1.x.y
tag to a Release on GitHub with the namev2.x.y
and add a deep-link to the release heading inCHANGELOG.md
- Pull the latest
Hotfix releases follow the same process as standard releases above, but the release-*
branch should be branched off latest main
instead of dev
. Once the stable hotfix is published, the release-*
branch should be merged back into both main
and dev
just like a normal release.
Experimental releases use a manually-triggered Github Actions workflow and can be built from any existing branch. to build and publish an experimental release:
- Commit your changes to a branch
- Push the branch to github
- Go to the Github Actions UI for the release-experimental.yml workflow
- Click the
Run workflow
dropdown - Leave the
Use workflow from
dropdown asmain
- Enter your feature branch in the
branch
input - Click the
Run workflow
button
Nightly releases happen automatically at midnight PST via a cron-driven workflow that is essentially the same as the experimental releases, but also performs some validations after the release.
This repository supports handful of environment variables to streamline the local development/testing process.
REMIX_DEBUG
By default, the Remix rollup
build will strip any console.debug
calls to avoid cluttering up the console during application usage. These console.debug
statements can be preserved by setting REMIX_DEBUG=true
during your local build.
REMIX_DEBUG=true pnpm watch
LOCAL_BUILD_DIRECTORY
When developing Remix locally, you often need to go beyond unit/integration tests and test your changes in a local Remix application. The easiest way to do this is to run your local Remix build and use this environment variable to direct rollup
to write the output files directly into the local Remix application's node_modules
folder. Then you just need to restart your local Remix application server to pick up the changes.
# Tab 1 - create and run a local remix application
npx create-remix
cd my-remix-app
npm run dev
# Tab 2 - remix repository
LOCAL_BUILD_DIRECTORY=../my-remix-app pnpm watch
Now - any time you make changes in the Remix repository, they will be written out to the appropriate locations in ../my-remix-app/node_modules
and you can restart the npm run dev
command to pick them up 🎉.
