Someone uses ESLint/TSLint for Pulumi? What are configs you recommend?

I recommend using ESLint (TSLint is deprecated) and use the same config you use for all your other JS/TS code 🙂 probably with Prettier for formatting rules

+1 for prettier/eslint combo, using the

@typescript-eslint

plugin. if you are looking for something to get you started, this is our

.eslintrc.json

file

{
  "parser": "@typescript-eslint/parser",
  "plugins": [
    "@typescript-eslint",
    "prettier"
  ],
  "extends": [
    "eslint:recommended",
    "plugin:@typescript-eslint/recommended",
    "prettier/@typescript-eslint",
    "plugin:prettier/recommended"
  ],
  "rules": {
    "@typescript-eslint/member-naming": [
      "error",
      {
        "private": "^__",
        "protected": "^_"
      }
    ],
    "@typescript-eslint/camelcase": [
      "error",
      {
        "properties": "never"
      }
    ],
    "camelcase": "off"
  },
  "env": {
    "node": true
  },
  "parserOptions": {
    "ecmaVersion": 2018,
    "sourceType": "module"
  }
}

and our prettierrc json

{
  "$schema": "<http://json.schemastore.org/prettierrc>",
  "singleQuote": true,
  "trailingComma": "none",
  "endOfLine": "lf",
  "semi": false,
  "printWidth": 120
}

FWIW, we use tslint in Pulumi itself

I would consider moving away from it soon - Palantir has basically said it's no longer interested in maintaining it, so at some point it's going to block you from using new TypeScript features because TSLint won't parse

Thanks for all your input. @broad-helmet-79436 @nice-guitar-97142 @tall-librarian-49374 @ambitious-ram-5811
