tauri-latest-json

Generate a latest.json file for Tauri auto-updates, supporting multi-platform builds (Windows, macOS Intel/ARM, Linux).

This crate scans your Tauri bundle directory for installers and outputs a valid latest.json for the Tauri Updater.

Features

• Detects installers: .msi, .exe, .dmg (Intel/ARM), .AppImage, .deb, .rpm, .tar.gz
• Auto-detects platform keys from filenames
• Reads version from package.json or Cargo.toml
• Generates a single multi-platform latest.json
• Works as both a library and a CLI

Install

Library:

[dependencies]

cargo install tauri-latest-json

CLI Usage

tauri-latest-json <download_url_base> <notes>
