Agent Skills: tauri-app-sidecar-nodejs

Bundle and run a Node.js process as a sidecar alongside a Tauri v2 app with lifecycle management. Use when integrating a Node.js backend as a sidecar binary, managing sidecar start/stop lifecycle, or packaging Node.js executables per platform.

Description
"Bundle and run a Node.js process as a sidecar alongside a Tauri v2 app with lifecycle management. Use when integrating a Node.js backend as a sidecar binary, managing sidecar start/stop lifecycle, or packaging Node.js executables per platform."

When to use this skill

ALWAYS use this skill when the user mentions:

  • Running Node.js as a sidecar process in Tauri
  • Packaging Node.js binaries alongside the app
  • Managing sidecar lifecycle (start, stop, logging)

Trigger phrases include:

  • "sidecar", "node.js sidecar", "nodejs backend", "sidecar packaging", "bundled node"

How to use this skill

  1. Compile Node.js to a standalone binary using tools like pkg or nexe: 
    npx pkg server.js -t node18-macos-x64,node18-win-x64,node18-linux-x64
  2. Place sidecar binaries in src-tauri/binaries/ with platform-specific naming: 
    src-tauri/binaries/node-server-x86_64-apple-darwin
src-tauri/binaries/node-server-x86_64-pc-windows-msvc.exe
src-tauri/binaries/node-server-x86_64-unknown-linux-gnu
  3. Configure the sidecar in tauri.conf.json: 
    { "bundle": { "externalBin": ["binaries/node-server"] } }
  4. Start the sidecar from Rust: 
    let sidecar = app.shell().sidecar("node-server").unwrap();
let (mut rx, child) = sidecar.spawn().unwrap();
  5. Configure shell permissions for the sidecar in capabilities
  6. Manage lifecycle: stop the sidecar gracefully on app exit using the child process handle

Outputs

  • Sidecar binary packaging per platform
  • Sidecar configuration in tauri.conf.json
  • Start/stop lifecycle management in Rust
