Contributing

Local development setup

Follow these steps to get the project setup on your local machine:

# Clone repo
git clone https://github.com/iFixit/core-primitives.git && cd core-primitives

# Install dependencies
npm install

Adding or Updating Primitives

1. Create a new branch

Create a new branch for your changes:

git checkout -b <branch>

2. Commit and push changes

Apply your changes to index.json, and keep index.d.ts in sync.

3. Test your build

Run npm run build and verify core-primitives.css and core-primitives.less are correct.

4. Open a pull request

Use GitHub to create a pull request for your branch.

5. Bump the package version

After your pull request has been approved, bump the package version by running:

npm version [major | minor | patch]

Running npm version will build, bump the version, and write the new data to package.json and package-lock.json. It will also create and push a version commit and tag.

Note: In the context of @core-ds/primitives, significant changes to the library or workflow, or removing primitives would be considered a major update, adding or updating primitives would be considered a minor update, and fixing primitives would be considered a patch. Non-code changes (e.g. documentation) do not require a version bump.

6. Publish to NPM

npm publish

7. Create a release

After your pull request has been merged, create a new release to document your changes. Use the tag you generated in step 4 to create the release.
