Welcome to the world of RESTful APIs! In this guide, we will step through the process of creating a simple API that saves contact information for individuals using Node.js, Express, MongoDB, and TypeScript. Whether you are a budding developer or a seasoned pro, follow along to bring your API to life!

Project Versions

This project comes in two versions:

• Version 1.0.0: This version allows you to run the server directly after cloning. It creates a simple RESTful API over HTTP. You can access it here.
• Version 2.0.0: In this version, you’ll have a more secure and controlled API. It’s recommended to read about how to secure RESTful API applications beforehand. You can access this version here.

Requirements

Before getting started, you’ll need the following:

• Node.js: You can download it from here.
• TypeScript: Install TypeScript globally via npm using the command:

npm install -g typescript ts-node

Getting Started

Follow these steps to get your API up and running:

1. Install MongoDB on your machine, or use a service like mLab or Compose.
2. Replace the mongoURL in lib/app.ts with your MongoDB address.
3. Clone the repository using:

git clone git@github.com:dalenguyen/rest-api-node-typescript.git .

4. Install the dependencies with:

npm install

Starting the Server

Now that everything is set up, let’s start the server:

• For development mode, run:

npm run dev

• For production mode, run:

npm run prod

Testing Your API

Once your server is running, it’s time to test it out:

Version 1.0.0 (HTTP)

The default URL is: http://localhost:3000

• To retrieve all contacts, send a GET request to http://localhost:3000/contact.

Version 2.0.0 (HTTPS)

The default URL is: https://localhost:3000

• Note that the key and cert in the config folder are for testing purposes only; you will need to generate your own for production use.

Troubleshooting

If you run into issues while setting up your API, here are some troubleshooting ideas:

• Ensure that your MongoDB service is running properly.
• Double-check the mongoURL in your code to make sure it points to the correct MongoDB instance.
• Make sure that your Node.js installation is successful and that the required packages are installed.
• Don’t forget, if you’re facing any challenges or have questions, you can reach out for support. For more insights, updates, or to collaborate on AI development projects, stay connected with fxis.ai.
