This puts in the README what has so far been an informal policy, based
on Slack and Paper dicussions.

Anyone should feel free to change this!

# noredink-ui
UI widgets we use.
## Versioning policy
We try to avoid breaking changes and the associated major version bumps in this package. The reason for that is to avoid the following scenario:
```
|
x 4.6.0: Adding RadioButton widget
|
x 5.0.0: Breaking change in the TextArea widget
|
x 5.0.1: Styling fix in the Checkbox widget
|
```
Suppose you just released version `5.0.1`, a small styling fix in the checkbox widget, for a story you're working on. If the project you're working in currently pulls in `noredink-ui` at version `4.x`, then getting to your styling fix means pulling in a new major version of `noredink-ui`. This breaks all `TextArea` widgets across the project, so those will need to be fixed before you can do anything else, potentially a big effort.
To prevent these big Yaks from suddenly showing up in seemingly trivial tasks we prefer to avoid breaking changes in the package. Instead when we need to make a breaking change in a widget, we create a new module for it `Nri.Ui.MyWidget.VX`.
We should change this process if we feel it's not working for us!
## Examples
This repo contains an app showcasing all of these UI widgets.
To see them locally:
```
make styleguide-app/elm.js
```
Open `styleguide-app/index.html` in your browser.
Alternatively, you may use elm-reactor. Please be aware that you'll need to globally
install fonts (in particular, Muli) if you go this route.
## Tests
Run tests with
```
make test
```
### CI (Travis)
Travis will run `make ci` to verify everything looks good.
You can run this locally to catch errors before you push!
