⚡Refactor Node.js Express APIs into serverless Azure Functions APIs

This repository contains the source code for the Refactor Node.js Express APIs into serverless Azure Functions APIs module.

💫 Overview

This project was created to help represent a fundamental app written with Node Express APIs and TypeScript that can be shifted to serverless functions with TypeScript.

The client-side (Front-end) app is Angular. However, it could just as easily be Vue or React. The vacation theme is used throughout the app.

🔧 Technologies/Tools used

• ✅ Visual Studio Code
  • ✅ Visual Studio Code Extension Marketplace
• ✅ Node.js
  • ✅ Visual Studio Code Extension for Node on Azure
• ✅ TypeScript
• ✅ Angular
• ✅ Express.js
• ✅ Azure Functions
  • ✅ Azure Functions Core Tools

❓Why

I love Node.js and Express.js for creating APIs! These require a server and paying for that server in the cloud. Shifting to serverless alleviates the cost of server upkeep, helps scale up and down easily, and reduces the surface area of the middleware required for a robust Express app. Is it perfect? No, of course not! But this is a solid option if these factors affect you.

🎯 Prerequisites

Make a copy of the env.example file named .env, in the root of the project. It should contain the following code.

.env

NODE_ENV=development
PORT=7070
WWW=./

🏁 Getting Started

1. Clone this repository

   git clone https://github.com/MicrosoftDocs/mslearn-module-shifting-nodejs-express-apis-to-serverless learn-functions
   cd learn-functions

2. Install the npm packages

   npm install

3. Build the Node.js, Express.js and the Angular code

   npm run full:build

4. Run the app

   npm run node:start

🐞 Debug Node.js, Express.js and Angular

1. Stop any debugging sessions that may be currently running

2. Open proxy.conf.json and set the port to 7070

3. Open the VS Code Command Palette F1

4. Type View: Show Debug and press ENTER

5. Select Debug Express and Angular

6. Press F5

7. Open the browser to http://localhost:4200

You may now set break points in the Express and Angular code.

🐞 Debug Functions and Angular

1. Stop any debugging sessions that may be currently running

2. Open proxy.conf.json and change the port to 7071

3. Open the VS Code Command Palette F1

4. Type View: Show Debug and press ENTER

5. Select Debug Functions and Angular

6. Press F5

7. Open the browser to http://localhost:4200

You may now set break points in the Functions and Angular code.
