Eslint-config-tyler NPM

eslint-config-tyler

Tyler's ESLint & Prettier configuration.

It's opinionated. It works out of the box.

It supports both Node.js projects and React frontend projects. It will detect existence of react to enable React & frontend rules.

Installation

yarn add --dev eslint-config-tyler

Usage

Create eslint.config.mjs:

import config from 'eslint-config-tyler/eslint.config.mjs';

export default config;

Create prettier.config.mjs:

import config from 'eslint-config-tyler/prettier.config.mjs';

export default config;

Run:

yarn eslint . --fix

Configuration

If you need to change some configuration:

import config from 'eslint-config-tyler/prettier.config.mjs';

config.singleQuote = false;

export default config;

Ignore

ESLint

import config from 'eslint-config-tyler/eslint.config.mjs';

config[0].ignores = ['lib/', 'demo/'];

export default config;

Please note that you should NOT add any other keys to config[0], because according to ESLint's documentation:

if an ignores key is used without any other keys in the configuration object, then the patterns act as global ignores. Ref: https://eslint.org/docs/latest/use/configure/ignore

Prettier

You need to create a .prettierignore file.

It cannot be configured in prettier.config.mjs file, unfortunately.

Config rules:

config[1].rules[ruleName] = 'off' | 'warn' | 'error';

We should not change config[0] since it is for ignore only.

Format on Save with VS Code

"editor.defaultFormatter": "esbenp.prettier-vscode",
"editor.formatOnSave": true,
"editor.codeActionsOnSave": {
  "source.fixAll.eslint": "explicit"
},

Notes

To make eslint-plugin-react-hooks work, your react component shouldn't be wrapped. For example: const App = auto(() => '') doesn't work because it is wrapped by auto. related: https://github.com/jsx-eslint/eslint-plugin-react/issues/3848 It works if I write it like this: const App = auto(function App() { return ''; }).

Todo

do no allow blank lines between public class members?
do not allow blanks lines unless next is a function or class or comment line?
it is broken due to: https://github.com/typescript-eslint/typescript-eslint/issues/10338
