FAQPage Schema
How do I run a Node.js backend inside a Tauri desktop app without requiring users to install Node.js?▼

Tauri supports running a Node.js sidecar to provide JavaScript backend functionality in desktop apps without requiring end-users to install Node.js. The sidecar runs as an isolated process alongside the frontend.

How does frontend to sidecar communication work in a Tauri application?▼

Frontend to sidecar communication in a Tauri application uses the Shell plugin for seamless IPC. This mechanism allows the frontend to interact with the Node.js backend process directly.

Does the Tauri Node.js sidecar approach work across Windows, macOS, and Linux?▼

Yes, the Tauri Node.js sidecar approach provides cross-platform compatibility across Windows, macOS, and Linux. It requires a Tauri v2 project and the packaged Node.js runtime.

What do I need to set up before configuring a Node.js sidecar in Tauri?▼

Before configuring a Node.js sidecar in Tauri, you need a Tauri v2 project and the tauri-shell plugin installed. You then create a sidecar directory and package the Node.js runtime.

Can I use a JavaScript backend with Tauri instead of the default Rust backend?▼

Yes, you can use a JavaScript backend with Tauri by embedding Node.js as a sidecar. This allows developers to leverage existing JavaScript backend code within the Tauri desktop application framework.
