If you’ve ever dreamt of crafting cross-platform desktop applications with the modern capabilities of JavaScript, look no further than Neuron, an innovative starter kit designed to make the process smoother and more efficient. Whether you’re a seasoned developer or just jumping into the world of Electron, this guide will walk you through setting up Neuron and getting started with your first project.

What is Neuron?

Neuron is an offline first starter kit that leverages Electron’s power, allowing developers to create stunning desktop applications across all platforms. It includes an arsenal of tools like PouchDB with remote CouchDB replication, supports ES6 through Babel, incorporates React, and utilizes Webpack and Sass, making it a fantastic choice for building robust applications.

Getting Started with Neuron

To kick things off, follow these steps to set up Neuron on your machine:

• Clone the repository:

git clone https://github.com/JamesTheHacker/Neuron

• Navigate into the Neuron directory:

cd Neuron

• Install the required dependencies:

npm install

Special Instructions for Windows Users

If you’re working on a Windows machine, you’ll need to make a minor adjustment to the project:

• Open package.json and remove the following line:

"postinstall": "bash postinstall.sh"

• Switch to using browser adapters in app.js by setting:

const localDB = new PouchDB('app', { adapter: 'websql' })

Running Your Application

To launch your app, use the command:

npm start

This command will build the necessary JS and CSS files, and then open the Electron application. It’s important to note that by default, devtools are disabled. To enable them, simply uncomment the line:

win.webContents.openDevTools()

Understanding PouchDB and CouchDB Integration

PouchDB acts almost like a trusty librarian, keeping your books (data) organized and in sync between your shelves (local and remote databases). Consider it as your application’s local storage that seamlessly connects to a remote CouchDB. This relationship is crucial for creating an offline first application.

If you want to utilize remote CouchDB, ensure it’s installed securely on a server of your choice. Enter the configuration details such as host, port, and credentials in the .env file:

COUCH_PROTOCOL=http
COUCH_HOST=192.168.0.1
COUCH_PORT=5984
COUCH_DB=app
COUCH_USERNAME=username
COUCH_PASSWORD=secret_password

Adding CORS Configuration

Configuring CORS is a crucial step to allow your app to communicate with CouchDB securely. To set this up, execute:

npm run add-cors http://127.0.0.0:5984 --username user --password secret_password

This command enables your application to access the remote CouchDB from your local environment.

Organizing Your Project with Webpack

Neuron employs Webpack to build your CSS and JavaScript files into single bundles. This not only helps in organizing but also improves the application performance by ensuring CSS loads before JavaScript:

• All CSS files are stored in the app/css directory and built using Sass.
• JavaScript files reside in the app/js directory, with built-in support for ES6 and React.

Troubleshooting Guide

If you encounter issues while setting up or running Neuron, here are some strategies to consider:

• Make sure all dependencies are correctly installed. You can remove the existing node_modules folder and run npm install again.
• Check your .env configuration carefully for any typos.
• For Windows users, ensure the browser adapters are set correctly in app.js.
• Try running the application in debug mode to capture any error logs for further analysis.
