Unable to find typings.d.ts and declare modules in angular 2 typescript app

Question

I am new to Typescript and Angular 2. I need to install an npm dependency and use it in my angular 2 app.

The dependency is https://www.npmjs.com/package/ng2-stomp-s

Answer 1

If you are not using new version of angular you can't find typings.d.ts file in your project. My suggestion is to update your project using angular CLI https://cli.angular.io/

Answer 2

My two cents to this conversation:

In your tsconfig.json file make sure that you have the right path for your typings.d.ts file

"typeRoots": [ "node_modules/@types", "../src/typings.d.ts" ],

Answer 3

It seems like your Typescript compiler tries to compile files from node_modules directory.

Please make sure you have this excluding rule in your tsconfig.json file:

{ 
  "compilerOptions": {},
  "exclude": [
    "node_modules"
  ]
}

Btw. you need just one of @types and typings. The second one is deprecated, all you need is proper @types packages included in your dev dependencies. Hope it helps!

EDIT: I think there shouldn't be any Typescript files in npm package, so I've created a topic with fix on this repository's github: https://github.com/devsullo/ng2-STOMP-Over-WebSocket/issues/5
