This repository is a very contrived package project, aiming to show how elm-review and the CLI are used in a project, and showcase the output by actually running them in your terminal.


Configuration lies in the review/ directory. There is an elm.json which lists the dependencies containing review rules we wish to use. It also contains a ReviewConfig.elm file, in which we explicitly choose the rules we want to enable.

The imported rules come from the review-unused and review-debug packages in the Elm package registry.

Custom rules

There are two custom rules in this project:

  • NoDefiningColorsOutsideOfUiColor: This rule prevents defining colors (using Css.hex) outside of the Ui.Color module, which is the central location where we define colors in the application.
  • NoUsingHtmlButton: This rule prevents users from using Html.button and Html.Styled.button, because we already have a great module to create buttons with the Ui.Button.

Both rules are found in the review/ directory. You can find their corresponding tests in review/tests/.

Running it

You can run the review by running npm run review, which will run elm-review .. This means it will run elm-review on all the Elm files in the project.

You can also run the fix mode by running npm run review:fix, which will run in effect run elm-review . --fix.

In a CI environment

You can see what elm-review looks like when run in a CI like Travis here. (NOTE: I am currently experiencing a problem with tests running into invalid dependencies, preventing the display of review problems. I would really appreciate some help with this!)

You can’t perform that action at this time.
