How to use TypeScript definitions @types in ionic2 project

Question

Ionic2 now use @types to support for third-party libraries.

I installed

npm install --save @types/gapi.auth2

But I don't know how to add my project to use it. Please help me

Answer 1

It should be pretty easy after you have installed @types/gapi.auth2, just add in your tsconfig.json in compilerOptions section the following line:

"types": ["gapi.auth2"]

And make sure you are using typescript 2.x

Hope this helps.
