> [!IMPORTANT]
> This config uses [new flat config style](https://eslint.org/docs/latest/use/configure/configuration-files-new) since v19.
## Priority
1. Avoid ["Possible Problems"](https://eslint.org/docs/latest/rules/#possible-problems)
2. Enable ["Suggestions"](https://eslint.org/docs/latest/rules/#suggestions) if reasonable or fixable
3. Use Prettier for stylistic formatting issues
## Install
```console
$ npm i -D eslint eslint-config-teppeis
```
and run `npx eslint-config-teppeis --init` to generate initial config files.
## Usage
Load `eslint-config-teppeis` and export default `build()` in your `eslint.config.js`:
```js
import { build } from "eslint-config-teppeis";
import { mocha } from "eslint-config-teppeis/configs/mocha";
export default await build(
{ base: "node18", typescript: true, esm: true },
mocha,
{
ignores: ["dist", "test/fixtures"],
},
);
```
### Options
- `base` (enum, required): `es2021`, `es2022`, `es2023`, `node18` or `node20`
- `typescript` (boolean, default false): use TypeScript
- `project` (boolean|string|srting[], default false): the property of `parserOptions` to enable linting with type information
- `esm` (boolean, default false): treat `.js` and `.ts` as ESM for a project that configures `type:module` in `package.json`
## Configs for customization
### Pure ECMAScript
Configs for ECMAScript versions
```js
import { es2021 } from "eslint-config-teppeis/configs/es2021";
export default [es2021];
```
- `es2021`
- `es2022`
- `es2023`
### Node.js
Configs for [Node versions](https://github.com/nodejs/Release)
- `node18` (v18.18+ Maintenance)
- `node20` (v20.9+ Active LTS)
```js
import { node18 } from "eslint-config-teppeis/configs/node18";
export default [node18];
```
### TypeScript
Configs for TypeScript
- `typescript`: Enable rules that don't require type information
- `typescriptTypeChecked`: Require type information
```js
import { node18, typescript } from "eslint-config-teppeis/configs";
export default [node18, typescript];
```
### ES Modules
By default, only `*.mjs` and `*.mts` are treated as ES Modules in configs for Node.js.
If you use `type:module` in package.json, use `esm: true` like:
```js
import { build } from "eslint-config-teppeis";
export default build({ base: "node18", esm: true });
```
### Browsers
This enables globals for browsers.
```js
import { es2023, browser } from "eslint-config-teppeis/configs";
export default [es2023, browser];
```
### Mocha
This enables globals for Mocha like `describe` or `it` only in `**/test/*.js`.
```js
import { es2023, mocha } from "eslint-config-teppeis";
export default [es2023, mocha];
```
## Note: Prettier
Just intall `prettier` and use it with `eslint-config-teppeis`.
These configs don't include rule settings that conflict with Pretteir.
