Extend

You can extend from an external ruleset. This keeps your project light as you add one line instead of many.

For example, using:

eslint:recommended

Gives you rules covered in conf/eslint-recommended.js of the ESLint repo.

See also conf/eslint-all.js.

eslint:all

See the Extending section in the docs.

Here is an example from the docs:

{
    "plugins": [
        "react"
    ],
    "extends": [
        "eslint:recommended",
        "plugin:react/recommended"
    ],
    "rules": {
       "react/no-set-state": "off"
    }
}
