## Release Process
|
|
|
|
Chart.js relies on [Travis CI](https://travis-ci.org/) to automate the library [releases](https://github.com/chartjs/Chart.js/releases).
|
|
|
|
|
|
|
|
### Releasing a New Version
|
|
|
|
|
|
|
|
1. draft release notes on [GitHub](https://github.com/chartjs/Chart.js/releases/new) for the upcoming tag
|
2018-12-16 11:58:29 +01:00
|
|
|
1. update `master` `package.json` version using [semver](https://semver.org/) semantic
|
2016-08-28 17:34:22 +02:00
|
|
|
1. merge `master` into the `release` branch
|
|
|
|
1. follow the build process on [Travis CI](https://travis-ci.org/chartjs/Chart.js)
|
|
|
|
|
|
|
|
> **Note:** if `master` is merged in `release` with a `package.json` version that already exists, the tag
|
|
|
|
creation fails and the release process is aborted.
|
|
|
|
|
|
|
|
### Automated Tasks
|
|
|
|
Merging into the `release` branch kicks off the automated release process:
|
|
|
|
|
|
|
|
* build of the `dist/*.js` files
|
|
|
|
* `bower.json` is generated from `package.json`
|
|
|
|
* `dist/*.js` and `bower.json` are added to a detached branch
|
|
|
|
* a tag is created from the `package.json` version
|
|
|
|
* tag (with dist files) is pushed to GitHub
|
|
|
|
|
|
|
|
Creation of this tag triggers a new build:
|
|
|
|
|
|
|
|
* `Chart.js.zip` package is generated, containing dist files and examples
|
|
|
|
* `dist/*.js` and `Chart.js.zip` are attached to the GitHub release (downloads)
|
|
|
|
* a new npm package is published on [npmjs](https://www.npmjs.com/package/chart.js)
|
|
|
|
|
|
|
|
Finally, [cdnjs](https://cdnjs.com/libraries/Chart.js) is automatically updated from the npm release.
