# eslint-config-cheminfo

Shared ESLint config for cheminfo and ml.js projects.

> [!IMPORTANT]  
> Configs now require using the ESLint Flat Config format.
> See the [migration guide](https://github.com/cheminfo/eslint-config/blob/main/MIGRATION.md) for more information.

## Installation

```console
npm i -D eslint-config-cheminfo eslint
```

## Usage

Create a `eslint.config.mjs` file with the following contents:

```js
import { defineConfig } from 'eslint/config';
import cheminfo from 'eslint-config-cheminfo';

export default defineConfig(cheminfo);
```

You can then customise the config for your project.

Create ESLint scripts in your `package.json`:

```json
{
  "scripts": {
    "eslint": "eslint src",
    "eslint-fix": "npm run eslint -- --fix"
  }
}
```

## Exported configurations

This package exports three separate configurations:

- [`eslint-config-cheminfo/base`](configs/base.js): The base config with most rules. At least this config should be used in all projects.
- [`eslint-config-cheminfo/jsdoc`](configs/jsdoc.js): Rules from the [jsdoc plugin](https://github.com/gajus/eslint-plugin-jsdoc) to help improve the documentation of our libraries.
- [`eslint-config-cheminfo/unicorn`](configs/unicorn.js): Additional opinionated rules selected from the [unicorn plugin](https://github.com/sindresorhus/eslint-plugin-unicorn).
- [`eslint-config-cheminfo/vitest`](configs/vitest.js): Rules from the [Vitest plugin](https://github.com/vitest-dev/eslint-plugin-vitest).

The default export from [`eslint-config-cheminfo`](configs/cheminfo.js) combines all of them.

## Extensions of this config

### TypeScript

## React

## TypeScript and React

To extend both the TypeScript and React configs, use the following template:

```js
import { defineConfig } from 'eslint/config';
import typescript from 'eslint-config-cheminfo-typescript';
import react from 'eslint-config-cheminfo-react/base';

export default defineConfig(typescript, react);
```
