urlprotocol

A Node.js library to handle custom URL protocols and route them to specific API paths.

Installation

To install the package, use npm:

npm install urlprotocol

Usage

The library allows you to define custom URL protocols and route them to specific API paths. Below is an example of how to use the package:

Example

Create a file named test.js and add the following code:

const CustomProtocolHandler = require('urlprotocol');

const protocolHandler = new CustomProtocolHandler('hello');

protocolHandler.register('/alertmessage', (req, res) => {
    res.writeHead(200, { 'Content-Type': 'application/json' });
    res.end(JSON.stringify({ message: 'This is an alert message!' }));
});

protocolHandler.start(3000);

In this example, when the URL hello://alertmessage is called, it will respond with a JSON message: {"message":"This is an alert message!"}.

API

CustomProtocolHandler

• constructor(protocol)

  • Creates a new CustomProtocolHandler for the specified protocol.

• register(path, handler)

  • Registers a handler function for the specified path.

• start(port)

  • Starts the HTTP server on the specified port.

Full Example

Here's a complete example of how to use the library:

const CustomProtocolHandler = require('urlprotocol');

const protocolHandler = new CustomProtocolHandler('hello');

protocolHandler.register('/alertmessage', (req, res) => {
    res.writeHead(200, { 'Content-Type': 'application/json' });
    res.end(JSON.stringify({ message: 'This is an alert message!' }));
});

protocolHandler.register('/greeting', (req, res) => {
    res.writeHead(200, { 'Content-Type': 'text/plain' });
    res.end('Hello, world!');
});

protocolHandler.start(3000);

In this example, two paths are registered: /alertmessage and /greeting. The hello://alertmessage URL will respond with a JSON message, and the hello://greeting URL will respond with a plain text message.
