ESLint – Configuring “no-unused-vars” for TypeScript

by

It’s a bit buried in the documentation, but if you add some things to the ‘extends’ property, you can use both the rules recommended by ESLint like no-unused-vars, and have it actually work in Typescript. Like so:

"extends": [
        "eslint:recommended",
        "plugin:@typescript-eslint/eslint-recommended",
        "plugin:@typescript-eslint/recommended"
    ],

@typescript-eslint/recommended seems to be the thing that allows eslint:recommended to deal with Typescript constructs effectively. Not sure how it would affect your other extensions though.
