interprocess: 💬 A scalable and type-safe Electron IPC management tool with enhanced DX

> Electron IPC is good, but difficult to maintain and scale, either because of the numerous channels you have to remember, or because of the inconsistent API between processes and the absence of inferred types of your channels and handlers. These are some of the things that interprocess comes to solve!

💬 Features

- 🚀 Best-in-class DX with a fully-typed API
- 🧠 Enchanced and consistent API
- 🔥 Type-safe and scalable
- 🪄 Code splitting support
- 🕸️ All edges connected (APIs to handle all processes)
- 💖 invoke and handle methods in both processes with the same expected behavior

💬 Installation

In your terminal, run:
``bash
yarn add interprocess

OR

npm i interprocess
`

💬 Usage

Let's build something simple that can show you some of the interprocess's power!

First, create the following folders at src:

- shared/ipcs (this folder structure is optional)

Then, create a file named as index.ts in the ipcs folder with the following content:

`ts
import { createInterprocess } from 'interprocess'

export const { ipcMain, ipcRenderer, exposeApiToGlobalWindow } =
createInterprocess({
main: {
async getPing(_, data: 'ping') {
const message = from renderer: ${data} on main process

console.log(message)

return message
},
},

renderer: {
async getPong(_, data: 'pong') {
const message = from main: ${data} on renderer process

console.log(message)

return message
},
},
})
`

On the main process:

`ts
import { BrowserWindow, app } from 'electron'

import { ipcMain } from 'shared/ipcs'

const { handle, invoke } = ipcMain

app.whenReady().then(() => {
const mainWindow = new BrowserWindow({
webPreferences: {
preload: path.join(__dirname, '../preload/index.js'),
sandbox: false, // sandbox must be false
},
})

handle.getPing()

mainWindow.webContents.on('dom-ready', () => {
invoke.getPong(mainWindow, 'pong')
})
})
`

In the preload script:

`ts
import { exposeApiToGlobalWindow } from 'shared/ipcs'

const { key, api } = exposeApiToGlobalWindow({
exposeAll: true, // expose handlers, invokers and removers
})

declare global {
interface Window {
[key]: typeof api
}
}
`

On the renderer process:

`ts
const { invoke, handle } = window.api

invoke.getPing('ping')
handle.getPong()
``
This is a simple way to work with interprocess, but there's a lot of more cool features you can take advantage, like overrides, code splitting, invoker's response (for renderer and main process 🎉) and more. See the Knowledge section for more
