TSLint not working in VS Code

tslint-react is a tslint extension which has to be installed separately: npm install -g tslint-react. After installing, reload your VS Code window, and linting should work.

How I found the problem: I copied your config file into a project, went to View > Output to check for errors from the tslint process, and saw this. (be sure to select tslint from the dropdown near the top right)

Include the dependency in the package.json

This is package.json and its working for me.

{  "name": "functions",  "scripts": {    "lint": "tslint --project tsconfig.json",    "build": "tsc",    "serve": "npm run build && firebase serve --only functions",    "shell": "npm run build && firebase experimental:functions:shell",    "start": "npm run shell",    "deploy": "firebase deploy --only functions",    "logs": "firebase functions:log"  },  "main": "lib/index.js",  "dependencies": {    "firebase-admin": "~5.11.0",    "firebase-functions": "^1.0.0"  },  "devDependencies": {    "tslint": "^5.8.0",    "typescript": "^2.5.3"  },  "private": true}

Add the following in package.json"lint": "tslint --project tslint.json" fixed the issue for me.
