Everything you need to install Tezz and manage your projects from the terminal.

CLI Commands

The tezz CLI is your all-in-one tool for development and production.

Command	Description
`tezz init`	Scaffolds a new `app.tezz` file with a starter template.
`tezz dev <file>`	Starts the development server with hot-reloading enabled. Saving your file instantly restarts the server.
`tezz run <file>`	Compiles and runs a Tezz file directly in Node.js.
`tezz build <file>`	Compiles your Tezz code into raw JavaScript. Use `--target worker` to compile for Cloudflare Workers.
`tezz repl`	Starts an interactive Read-Eval-Print Loop for testing snippets on the fly.

Hot-Reloading in Action

When running tezz dev app.tezz, the CLI watches your file for changes. When a change is detected, it intercepts the signal, kills the current server, recompiles the AST, and spawns a new server instance—all in less than 300ms.
