IPC

A library for local interprocess communications on unix based systems.

Installation

You can install this module into your project.

yarn add @hoobs/ipc

Options

Options for creating an IPC server or client.

import { IPCOptions } from "@hoobs/ipc";

const options: IPCOptions = {
    id: "test",
    root: "./",
    namespace: "example",
    encoding: "utf8",
    maxConnections: 100,
}

The example above creates a sock file example.test.sock in the application's root.

| variable | Required | description | | -------------- | -------- | --------------------------------------------------------------------------------------- | | id | Yes | a unique name for the socket | | root | No | the path to store the Unix sock file, default is the app root | | namespace | No | adds a domain to the sock files | | encoding | No | text encoding for socket messages, default is utf8 | | maxConnections | No | this is the max number of connections allowed to a socket, default is 100 (server only) |

Server

Below is an example of a server implantation.

There are two types listeners;

• Event
• Route

Events are designed as void functions, where routes return a payload. Routes accept a path, parameters, and a body. Both requests and results are JSON objects.

import { IPCServer } from "@hoobs/ipc";

const server = new IPCServer({
    id: "test",
    maxConnections: 100,
});

// EVENTS
server.on("host", (data) => {
    console.log(data);
});

// ROUTES
server.route("hello", (request, response) => {
    response.send({
        message: `Hello ${request?.params?.name}`,
    });
});

server.start();

Client

The client can access a server's events and routes. Below is an example of a client implantation.

The two methods are;

• Emit
• Fetch

Emit sends a request to the server and doesn't expect a result. Fetch works much like HTTP calls. You need to define the route using the path parameter, and excepts parameters and a body object. Fetch is a promise, so it needs to be called with await or using the then method.

import { IPCClient } from "@hoobs/ipc";

const client = new IPCClient({
    id: "test",
});

// EVENTS
client.emit("host", {
    ip: "127.0.0.1",
});

// ROUTES
client.fetch("hello", {
    name: "Luke Skywalker",
}).then((response) => {
    console.log(response);
});
