Requirements

Node.js is the only requirement.

Install

• Clone the repository
• In each project inside services/ run npm install to download all the dependencies.

Note: this command should be run again every time you install/delete a package (which should not happen a lot)

Run

In each project, run node index.js so the server will start listening to requests.

---

Architecture

In the services/ folder you will find all the projects that makes your website. Each subfolder is a node.js project that contains:

• A package.json (and potentially some node_modules)
• An index.js file which is an HTTP server able to received requests
• Some logic used for the service to work correctly

---

At the start of your project, there are 2 services:

• gateway which is the clients' entry point. It receives all the requests and then redirect them to the correct service.
• files which is used to serve files. It is where your front files will go

---

To create a new service:

• Create a new folder inside services/
• Run npm init -y inside the created folder
• Create an index.js containing an HTTP server (and listening to a new port)
• Add any logic you want

---

To call a service:

2 external packages are allowed to transfer a request:

• http-proxy allows you to easily transfer a request "as-is" to another HTTP Server (you have an example in the gateway service)
• axios to perform specific REST requests.
