ember-template-lint-plugin-prettier

It uses Prettier to lint your handlebars templates with ember-template-lint. The plugin defines a - single - rule. That rule will compare your code with Prettier's output.

Here is an output example:

2:18  error  Replace `·{{@lastName}}··` with `{{@lastName}}`  prettier
  1 | <h1>A title</h1>
> 2 | <p>{{@firstName}}  {{@lastName}}   , welcome!</p>
  3 | <p>Text</p>

Install

yarn add -D prettier ember-template-lint-plugin-prettier

As peerDependencies, prettier and ember-template-lint will have to be installed in your project. Prettier version local to the project will be used (not any global one!).

Recommended configuration

A recommended configuration is available. To use it, merge the following object to your .template-lintrc.js file:

module.exports = {
  plugins: ["ember-template-lint-plugin-prettier"],

  extends: ["recommended", "ember-template-lint-plugin-prettier:recommended"]
};

The recommended set will apply these rules.

Configuration

Prettier can be configured via standard prettier config files.

Credits

This plugin has been inspired by the prettier plugin for Eslint.
