Deprecated

This extension is deprecated in favor of using Prettier for Handlebars natively using Prettier itself.

Prettier for Handlebars - A fork of Handlebars Formatter

This extension allow you to format handlebars files using the currently unreleased Prettier glimmer parser

Because it uses unreleased, it may break with future changes to Prettier.

This fork exists because of a difference in the hard coded Prettier dependency.

Currently Prettier for Handlebars uses Prettier v1.18.2 while Handlebars Formatter uses something more modern.

Because the Prettier glimmer parser is still experimental it tends to break. There were idempotency issues with versions above v1.18.2.

Once these are fixed then this extension will be updated accordingly.

Final reason: I, Alon, like my name better 🙂

This extension should respect options declared in .prettierrc. If you wish to provide specific overrides you can do so like this

{
  "singleQuote": true,
  "overrides": [
    {
      "files": "*.hbs",
      "options": {
        "singleQuote": false
      }
    }
  ]
}

Format your handlebars files with Prettier ... that's it!

Example below from a slightly complex template from Discourse
