tauri-latest-json

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

This CLI 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
• CLI-only tool (not intended as a Rust library dependency)

Install

cargo install tauri-latest-json

CLI Usage

tauri-latest-json <download_url_base> <notes>

tauri-latest-json help
tauri-latest-json version
tauri-latest-json --help
tauri-latest-json --version

Notes can contain spaces without quotes; all remaining args are combined.

Example:

tauri-latest-json https://example.com/downloads Initial release with details

latest.json is written to the current working directory.

Optional signature verification

Enable compile-time verification of signatures using the Tauri CLI:

cargo install tauri-cli
cargo run --features verify-signature -- <download_url_base> <notes>

If the paths are correct, you’ll see latest.json generated successfully.

Requirements

• Valid Tauri updater configuration (see the Tauri Updater docs)
• A Tauri signing key

pnpm tauri signer generate -w ~/.tauri/myapp.key

Platform Detection
