Electron

Electron is a cross-platform (Linux, Windows, macOS) way for creating desktop apps using TypeScript.

Electron embeds Chromium and Node.js in the generated app's binary. The generated app thus consists of two separate processes - the main process, and a renderer process.

  • The main process is runs the embedded node. This process can deal with the host OS - it is conceptually like a node repl running on your machine. In our case, the TypeScript code (in the src/ directory) gets transpiled by tsc into JavaScript in the build/app/ directory, which gets bundled in the generated app's binary and is loaded by the node (main) process when the app starts.

  • The renderer process is a regular web app that gets loaded into the embedded Chromium. When the main process starts, it creates a new "window" that shows this embedded Chromium. In our case, we build and bundle a static export of the Photos web app in the generated app. This gets loaded by the embedded Chromium at runtime, acting as the app's UI.
