 - **appName** `string`: The name that will be printed to the terminal.
 - **config** `Object`: The webpack configuration options to be provided to the webpack constructor.
-- **devSocket** `Object`: Required if `useTypeScript` is `true`. This object should include `errors` and `warnings` which are functions accepting an array of errors or warnings emitted by the type checking. This is useful when running `fork-ts-checker-webpack-plugin` with `async: true` to report errors that are emitted after the webpack build is complete.
 - **urls** `Object`: To provide the `urls` argument, use `prepareUrls()` described below.
 - **useYarn** `boolean`: If `true`, yarn instructions will be emitted in the terminal instead of npm.
 - **useTypeScript** `boolean`: If `true`, TypeScript type checking will be enabled. Be sure to provide the `devSocket` argument above if this is set to `true`.
-- **tscCompileOnError** `boolean`: If `true`, errors in TypeScript type checking will not prevent start script from running app, and will not cause build script to exit unsuccessfully. Also downgrades all TypeScript type checking error messages to warning messages.
 - **webpack** `function`: A reference to the webpack constructor.
