Linting

Given email correctness lies on a spectrum, Brail offers an eslint plugin to ascertain just how much email client support your code might have. As well as arbitrary linting rules, the plugin uses up-to-date data on email client support, sourced from caniemail.com (opens in a new tab).

Full credit for the data and other email wisdom: HTeuMeuLeu (opens in a new tab).

To install the plugin:

pnpm add -D @brail/eslint-plugin

Add the following to your eslint configuration:

{
  // ...
  plugins: ["@brail"],
  extends: ["plugin:@brail/recommended"],
  // ...
}
