Example Node.js API proxy server

This project contains an example proxy server which allows clients to make authenticated requests to an API.

Article

This project was created as a companion to an article I've written about creating a proxy server for API requests using Node.js: How to securely call an authenticated API from your front end

Frameworks & Libraries used

fastify - "Fast and low overhead web framework, for Node.js"
fastify-http-proxy - "Proxy your http requests to another server, with hooks."
dotenv - "Dotenv is a zero-dependency module that loads environment variables from a .env file into process.env"

Setup

npm install

Create an .env file for use in development:

API_KEY=abc123

The .env file will be automatically loaded by dotenv when you run the example server (see below).

Running the example server

npm start

Development

If you want to test out making changes to the example proxy server, I recommend installing nodemon. It will watch for any file changes you make and take care of restarting the server for you.

Once it is installed you can run it in your terminal:
