Advanced tools
Accessibility linting plugin for lit-html.
Most of the rules are ported from eslint-plugin-jsx-a11y, and made to work with lit-html templates and custom elements.
You'll first need to install ESLint:
$ npm i eslint --save-dev
Next, install eslint-plugin-lit-a11y:
$ npm install eslint-plugin-lit-a11y --save-dev
Note: If you installed ESLint globally (using the -g flag) then you must also install eslint-plugin-lit-a11y globally.
Add lit-a11y to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:
{
"plugins": ["lit-a11y"]
}
Then configure the rules you want to use under the rules section.
{
"rules": {
"lit-a11y/rule-name": 2
}
}
You may also extend the recommended configuration like so:
{
"extends": ["plugin:lit-a11y/recommended"]
}
By default, any tagged template literal that starts with html is linted. Example:
html`<img />`;
It could be the case, however, that you're using multiple rendering libraries in a project, like for example htm, which also uses a html tagged template literal, but has a slightly different syntax than lit-html. In this case you can specify the following option, to make sure only lit-html tagged template literals are linted:
{
"settings": {
"litHtmlSources": true
}
}
This will cause the plugin to lint only html tagged template literals that are imported from either 'lit-html' or 'lit-element'.
If you're importing lit-html from a package that re-exports lit-html, like for example @apollo-elements/lit-apollo, you can specify @apollo-elements/lit-apollo as a valid litHtmlSource like so:
{
"settings": {
"litHtmlSources": ["@apollo-elements/lit-apollo"]
}
}
