Electron is a software framework that combines the Chromium rendering engine with the Node.js runtime to facilitate the creation of cross-platform desktop applications. Its architecture utilizes a multi-process model, where a central main process manages the application lifecycle while separate renderer processes handle individual window interfaces. This design ensures stability and security by isolating web content from the underlying operating system. To enable communication between these isolated environments, the framework relies on a high-performance messaging system called Mojo. Developers can further secure their apps by implementing sandboxing and context isolation, which strictly control how web pages interact with privileged Node.js APIs. Specialized community versions, such as Brave’s Muon or castLabs, demonstrate how the framework can be modified to support advanced features like Chrome extensions or digital rights management.
