ESLint config for ioBroker projects

Installation

Install the package via

npm i @iobroker/eslint-config --save-dev

Getting started

Just extend this project in your lint config in your eslint.config.mjs.

import config from '@iobroker/eslint-config';

export default [...config];

And create a prettier.config.mjs with the following content:

import prettierConfig from '@iobroker/eslint-config/prettier.config.mjs';

export default prettierConfig;

Optionally, if you are using ESM modules, there is an additional config. Your eslint.config.mjs would then look like this:

import config, { esmConfig } from '@iobroker/eslint-config';

export default [...config, ...esmConfig];

ReactJS project

To use this config in a ReactJS project, your eslint.config.mjs would then look like this:

import config, { reactConfig } from '@iobroker/eslint-config';

export default [...config, ...reactConfig];

It is suggested to create separate eslint.config.mjs files for backend and for ReactJS.
