| |
| ### How to publish a new release |
| |
| 1. On the `main` branch, bump the version number in `package.json`: |
| |
| ```sh |
| npm version patch -m 'Release v%s' |
| ``` |
| |
| Instead of `patch`, use `minor` or `major` [as needed](https://semver.org/). |
| |
| Note that this produces a Git commit + tag. |
| |
| 1. Push the release commit and tag: |
| |
| ```sh |
| git push && git push --tags |
| ``` |
| |
| Our CI then automatically publishes the new release to npm. |
