Unable to find typings.d.ts and declare modules in

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-service

I have installed the necessary packages, but I need to add the following to my typings.d.ts file

declare module 'stompjs';
declare module 'sockjs-client';

I am unable to find the typings.d.ts file in my project.

I have tried the following so far,

npm install typings --global
npm install @types/stompjs
npm isntall @types/sockjs-client
typings install dt~stompjs --save
typings install dt~sockjs-client --save

I have typings.json file with contents,

{
  "dependencies": {
    "sockjs-client": "registry:dt/sockjs-client#1.0.3+20160727010356",
    "stompjs": "registry:dt/stompjs#2.3.0+20161111105645"
  }
}

When I run my angular 2 app with npm start it throws error as follows

ERROR in D:/Userfiles/subramanians/projects/hand-cricket/node_modules/ng2-stomp-service/dist/stomp.service.ts (27,2): Member 'config' implicitly has an 'any' type.

I am not sure what is causing the issue, I am guessing it is because I have not declared the modules in typings.d.ts

Please advise. Thank you.

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" ],

回答2:

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/

回答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
