Assuming you already have a project set-up. If you don’t have typescript within your node modules, add it using

• yarn add typescript

Next up we’ll add eslint and it’s typescript plugins (to the dev dependencies)

• yarn add –dev eslint
• yarn add –dev @typescript-eslint/parser
• yarn add –dev @typescript-eslint/eslint-plugin

ESList uses a configuration file in the shape of a .eslintrc.js file which should be placed in root folder of your project. Below is a sample

module.exports = {
    "parser": '@typescript-eslint/parser',
    "plugins": ['@typescript-eslint'],
    "extends": ['plugin:@typescript-eslint/recommended'],
    "rules": {
        "@typescript-eslint/no-parameter-properties": "off",
        "@typescript-eslint/no-explicit-any": "off"
    },
};

In the above we’ve turned off a couple of rules (the rule name will be listed alongside output from eslint when it’s run).

Now, to run eslint we use the following command

.\node_modules\.bin\eslint ./src/*.ts
