node.js - How to use 'crypto' module in Angular2?

Question

I install module:

npm install --save crypto

I import it to my component:

import { createHmac } from "crypto";

But I get error:

ERROR in -------------- (4,28): Canno t find module 'crypto'.

What am I doing wrong?

Answer 1

To use crypto NodeJS library with Typescript (Angular >= 2 for example) follow these steps:

1. npm install @types/node --save-dev to install NodeJS definitions

2. In tsconfig.ts file add the following:

   "files": [ "./node_modules/@types/node/index.d.ts" ]

3. Import the library where you want to use it with import * as crypto from 'crypto';
