Modify Rules

To add a new rule, turn off or modify the existing list of rules, append the rules in your eslint configuration file.

{
  rules: {
    "<new-rule>": "error",
    "no-unused-vars": "off",
    "id-length": ["warn", { min: 3, max: 20 }]
  }
}

To disable one or more rules throughout the file, add this at the top of your file.

/* eslint-disable  @typescript-eslint/no-unused-vars, @typescript-eslint/no-explicit-any */

To disable one or more rules in the next line,

/* eslint-disable-next-line <rule1>, <rule2> */

warning

The syntax below won't work

// eslint-disable-next-line <rule1>, <rule2>
/** eslint-disable-next-line  @typescript-eslint/no-unused-vars */

To run linting on your codebase,

npm run lint

yarn lint

For formatting non-js like .css, .html files you can use prettier alongside eslint. Prettier configuration, .prettierignore and usage of eslint with prettier in pre-commit hook can be referenced from my react-node-ts-monorepo.
