TypeScript usage

puppeteer-extra and most plugins are written in TS, so you get perfect type support out of the box. :)

If in doubt please use the following tsconfig (or compare with yours if you run into import issues):

tsconfig.json:

{
  "compilerOptions": {
    "outDir": "./dist",
    "target": "es2017",
    "module": "commonjs",
    "moduleResolution": "node",
    "lib": ["es2015", "es2016", "es2017", "dom"],
    "sourceMap": true,
    "declaration": true,
    "allowSyntheticDefaultImports": true,
    "esModuleInterop": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "strict": true,
    "noFallthroughCasesInSwitch": true,
    "noImplicitReturns": false,
    "noUnusedLocals": true,
    "noUnusedParameters": false,
    "pretty": true,
    "stripInternal": true
  },
  "include": ["./src/**/*.tsx", "./src/**/*.ts"],
  "exclude": ["node_modules", "dist", "./test/**/*.spec.ts"]
}

• Put your .ts files in a src/ subdirectory
• The compiled JS files (after running yarn tsc) will be in dist/
