ember-template-lint is a library that will lint your handlebars template and return error results.
For example, if the rule no-bare-strings is enabled, this template would be
in violation:
When the ember-template-lint executable is run, we would have a single result indicating that
the no-bare-strings rule found an error.
- Node.js
^14.18.0 || ^16.0.0 || >=18.0.0
npm install --save-dev ember-template-lintyarn add --dev ember-template-lintNote: this library is installed by default with new Ember apps.
While ember-template-lint does have a Node API, the main way to use it is through its executable, which is intended to be installed locally within a project.
Basic usage is as straightforward as
ember-template-lint .See documentation on workflow examples.
See documentation on the todo functionality.
You can turn on specific rules by toggling them in a
.template-lintrc.js file at the base of your project, or at a custom relative
path which may be identified using the CLI:
module.exports = {
extends: 'recommended',
rules: {
'no-bare-strings': true,
},
};For more detailed information see configuration.
| Name | Description | |
|---|---|---|
| ✅ | recommended | Enables the recommended rules. |
| 💅 | stylistic | Enables stylistic rules for those who aren't ready to adopt ember-template-lint-plugin-prettier (including stylistic rules that were previously in the recommended preset in ember-template-lint v1). |
| ⌨️ | a11y | Enables A11Y rules. Its goal is to include all A11Y related rules, therefore it does not follow the same SemVer policy as the other presets. Please see versioning for more details. |
Each rule has emojis denoting:
- what configuration it belongs to
- 🔧 if some problems reported by the rule are automatically fixable by the
--fixcommand line option
You can add a fixer to a rule. See fixer documentation for more details.
It is possible to share a config (extends) or plugin (custom rules) across projects. See ember-template-lint-plugin-peopleconnect for an example.
You can define and use your own custom rules using the plugin system. See plugin documentation for more details.
