# Publishing

For every push to the development, release or master branch some automated steps are done by Travis: setup a version number and publish to npm.

The version number is created as folows:

* take the version number from the package.json file
* use tags: alpha for the development branch, beta for releaase, and latest for master.
* ask npm what the most recently published version is for that tag and the current version
* add one to the minor version and publish using the tag and new versionnumber

Eg. the current version number in package.json is 0.30.0. On a push to development travis starts.\
It finds that the latest release tagged alpha is 0.30.0-alpha.1. It increase the last numer and publishes to 0.30.0-alpha.2\
The components are now available and can be used for example through jsdelivr: <https://cdn.jsdelivr.net/npm/openstad-components@0.30.01-alpha.2/dist/all.js>

This means that you do not need to update the number in package.json for every commit.

Details can be found in [.travis.yml](https://github.com/Amsterdam/openstad-components/blob/master/.travis.yml) and [set-publish-version.js](https://github.com/Amsterdam/openstad-components/blob/master/scripts/set-publish-version.js)
