Top Ways to Mock your server for testing/building Angular Project

 #1. Using Proxy 

Add a file proxy.conf.json

{

  "/rest": {

    "target": "http://tca-test-ems.tca.local:8080",

    "secure": false,

    "changeOrigin": true,

    "logLevel": "debug",

     "headers": {

      "Authorization": "Basic ZW1zdmljcm06OTclb3BzY2sh"

      }

    }

}

Run angular CLI using ng serve --proxy-config proxy.conf.json

#2. Exposing a brand-new Node Server Fake API:

Install

npm install -g json-server

Add a folder "server" and add two files : server.js and db.json

const app = require('express')();

app.get('/tier2/malfunctionPortalServiceApi/getIapsListForUser', (req, res) => {

  res.json([

    { id: 1, name: 'Node Mock IAP' }

  ]);

});

app.listen(3000);

Run that server. js in a new powershell window in VS Code
