Node.js

In a microservices architecture, our systems are broken down into dozens of small, focused services—like a User Service, an Order Service, and a Product Service. But when it comes to displaying this information to your users, different devices have very different needs. A web browser on a high-speed desktop computer wants a rich dashboard full of tables, sidebars, and graphs. A mobile app on a slow cellular network wants a simple, lightweight layout to save bandwidth and battery. A smartwatch app might only need a single line of text.

Electron is one of the most popular frameworks for building cross-platform desktop applications using web technologies like HTML, CSS, and JavaScript. Under the hood, Electron runs a multi-process architecture consisting of a Main Process (running Node.js) and one or more Renderer Processes (running Chromium to render the UI). Because of security risks, modern Electron applications isolate the Renderer Process from the operating system. This means you cannot access Node.js modules or system resources (like reading files or querying databases) directly from the Renderer UI.
