weirdpatterneslint-config-typescript
An opinionated set of ESLint rules for TypeScript projects
Installation
Install eslint-config-typescript:
$ npm install --save-dev eslint-config-typescript
Then, add eslint-config-typescript to the "extends" array in your ESLint file. Make sure to put it last, so it gets the chance to override other configs.
{
"extends": [
"typescript"
]
}
A few ESLint plugins are supported as well:
{
"extends": [
"typescript",
"typescript/react",
"typescript/prettier",
"typescript/prettier-react"
]
}
Note: typescript/prettier-react will automatically import typescript/prettier.
Example configuration
Using default prettier configurations:
{
"extends": [
"typescript",
"typescript/prettier"
],
"plugins": ["filenames", "jest"],
"env": {
"jest": true,
"node": true
},
"rules": {
"filenames/no-index": "error",
"filenames/match-exported": ["error", "kebab"],
"jest/no-disabled-tests": "error",
"jest/no-focused-tests": "error",
