Gojob ESLint

Feel free to extend our opinionated ESLint configurations.

TypeScript

With the deprecation of TSLint (we'll miss you, buddy), we decided to progressively switch all our linting processes to [ESLint].

Installation

You can extend our default configuration, in your own ESLint configuration:

{
  "extends": [
    "@gojob/eslint-config/typescript" // or typescript-react
  ],
}

Assuming you already installed typescript...

yarn add --dev eslint @gojob/eslint-config prettier
# or
npm install --save-dev eslint @gojob/eslint-config prettier

Integration with VSCode

At the present time, the ESLint plugin for VSCode has difficulties parsing/fixing TypeScript. Adding the following configuration to VSCode settings (.vscode/settings.json in your project) solves the problem:

{
  "eslint.validate": [
    "javascript",
    "javascriptreact",
    { "language": "typescript", "autoFix": true },
    "typescriptreact"
  ],
  "typescript.tsdk": "node_modules/typescript/lib"
}

FAQ

Q: I get the following error: Error while loading rule '@typescript-eslint/no-floating-promises': You have used a rule which requires parserServices to be generated. You must therefore provide a value for the "parserOptions.project" property for @typescript-eslint/parser.

A: You need to add json parserOptions: { project: "<my-ts-config>.json" } in your eslint config file, i.e. json parserOptions: { project: "./tsconfig.json" }.
