Getting started

Install npm package

npm i ng-blockchainx

If you are using Angular version >11 and run into an issue building. This is because polyfills are not included in the newest version of Angular.

• Install the required dependencies within your angular project:

npm install --save-dev crypto-browserify next-tick stream-browserify assert stream-http https-browserify os-browserify

• Within tsconfig.json add the following paths in compilerOptions so Webpack can get the correct dependencies

{
    "compilerOptions": {
        "paths" : {
        "crypto": ["./node_modules/crypto-browserify"],
        "stream": ["./node_modules/stream-browserify"],
        "assert": ["./node_modules/assert"],
        "http": ["./node_modules/stream-http"],
        "https": ["./node_modules/https-browserify"],
        "os": ["./node_modules/os-browserify"],
    }
}

• Add the following lines to polyfills.ts file:

import { Buffer } from 'buffer';

(window as any).global = window;
global.Buffer = Buffer;
global.process = {
    env: { DEBUG: undefined },
    version: '',
    nextTick: require('next-tick')
} as any;

• Create webpack.config.js file on root path and add below code

{
    resolve: {
        fallback: {
            url: require.resolve("url/")
        }
    }
}

after run npm install url

Once above setup done stop and start the angular project. If compilation success start integrating the services.
