flue dev

Synopsis

flue dev [--target <node|cloudflare>] [--root <path>] [--output <path>] [--config <path>] [--port <number>] [--env <path>]

Description

flue dev builds the selected project, starts a local server, watches project files, and reloads after relevant changes. Restart the command after changing flue.config.*; running servers do not re-resolve configuration fields.

Options

Option	Default	Description
--target <node|cloudflare>	Configuration value	Select the development target. Required unless supplied by configuration.
--root <path>	Selected config-file directory, or config search directory	Select the project root.
--output <path>	<root>/dist	Select the build output directory.
--config <path>	Auto-discovered flue.config.*	Select a configuration file.
--port <number>	3583	Select the local server port.
--env <path>	<config-base>/.env, when present	Select one alternate .env-format file loaded before configuration. Relative paths resolve from <config-base>. Shell values win.

Target-specific behavior

Node.js

Builds the Node artifact, starts the generated server, and rebuilds and respawns it after relevant file changes.

Cloudflare

Starts Vite with the official Workers integration. Cloudflare runtime bindings continue to use the official .dev.vars, .env, and CLOUDFLARE_ENV conventions.

Examples
