I have my .typingsrc file as below

proxy="http://pac.lbs.alcatel-lucent.com/proxy.pac:80"
http-proxy="http://pac.lbs.alcatel-lucent.com/proxy.pac:80"
https-proxy="http://pac.lbs.alcatel-lucent.com/proxy.pac:80"
rejectUnauthorized=false

If I want to specify user name with domain (domain\username) how should I do that?
I tried below one, did not work
proxy="domain\username:password@http://pac.lbs.alcatel-lucent.com/proxy.pac:80"

The problem is my password contains @ symbol.

When I open the url https://api.typings.org/entries/dt/core-js/versions/latest in browser I get the below response:

{"tag":"0.9.0+20170310221640","version":"0.9.0","description":null,"compiler":null,"location":"github:DefinitelyTyped/DefinitelyTyped/core-js/index.d.ts#8dd753de5a1e97fe75d9d25df3d78c227c409309","updated":"2017-03-10T22:16:40.000Z"}

Hi Please can somebody help me out :)

[unional]

Do you want to try npm install @types/core-js instead?

[abhilashdk2016]

Hi I can try. I am really new to all this. Do I have to do any other modifications for my package.json or systemjs.config.js if i go by this way.

[unional]

Nothing needed to change to the systemjs.config.js. Typings only needed in the node_modules folder so it can be discovered by the compiler / language service used by your IDE.

Install the typings as devDependencies:

npm install -D @types/core-js

Also, it is advisable to use the newer TypeScript (the @types above needs [email protected]+).

[unional]

And you don't need typings as you dependencies.

[abhilashdk2016]

So "typescript": "^1.8.10" should change to "typescript": "^2.0.0". Then execute npm install -D @types/core-js right?

[unional]

Yes, or as you do npm install -D typescript@*, it will install the latest, which is 2.2.1

[abhilashdk2016]

Hi Thanks it worked. Now in app.module.ts I can remove ///<reference path="../../typings/index.d.ts"/> this line right. It's giving red squiggly so.

[unional]

I don't know what that file is. 🌷

[abhilashdk2016]

I am working on Angular 2 Application. app.module.ts file contains the main module class for the application and In a tutorial I saw ///<reference path="../../typings/index.d.ts"/> being referenced. My concern is after installing typings using the way you said should I still need a reference to the typings/index.d.ts file or not.

[bensontrent]

The tutorial where you saw "///<reference path=" is likely an old tutorial, and that's right, you shouldn't need that reference, Reference paths were needed before typescript 2.0 They have been replaced with options in the tsconfig file to direct the typescript compiler to the locations of your types. See instructions in the handbook for consuming types.
