CLI

The daho command-line tool scaffolds projects, compiles the native library, runs your server, and diagnoses your toolchain. It ships in the daho_cli package.

Installation

dart pub global activate daho_cli

This installs a global daho command. Make sure Dart's pub global bin directory is on your PATH:

export PATH="$PATH":"$HOME/.pub-cache/bin"

If you haven't published or activated the CLI globally yet, you can always invoke it from a checkout:

dart run daho_cli:daho <command>

Commands

Command	Description
daho create <name>	Scaffold a new Daho project (server, routes, Dockerfile, README).
daho doctor	Check the toolchain (Dart, CMake, H2O) and report what's missing.
daho build	Compile the native H2O wrapper for the current platform.
daho run [entrypoint]	Build the native library if needed, then run the server.

build and run locate the resolved daho package via your project's package_config.json (walking up to the workspace root when needed), so run them from inside a project that depends on daho.

daho create

Scaffold a ready-to-run project with a server entry point, a top-level routes file, a Dockerfile, and a README.

daho create my_api
cd my_api
daho run

Options

Flag	Description
--local <path>	Emit a path dependency on a local daho package (useful while developing before daho is on pub.dev).
--force	Overwrite an existing directory.

# Point at a local checkout of the framework
daho create my_api --local ../daho/packages/daho

daho doctor

Verify your toolchain and get platform-specific guidance on anything missing.

daho doctor

It checks for the Dart SDK, CMake, and H2O, and prints exactly what to install on your platform — including WSL2 / Docker guidance on Windows, where there is no native H2O build.

daho build

Compile the native H2O wrapper for the current platform. The compiled library is cached, so this normally runs only once per machine (or after upgrading Daho).

daho build          # build if not already built
daho build --force  # force a clean rebuild

daho run

Build the native library if needed, then run your server. Defaults to bin/server.dart.

daho run                      # runs bin/server.dart
daho run bin/api.dart         # run a specific entrypoint
daho run --no-build           # skip the build step (library already compiled)

Platforms

H2O is a Unix server, so build and run work on macOS and Linux. On Windows, use WSL2 (treat it as Linux) or the generated Dockerfile (a Linux container). daho doctor prints the right guidance for your platform.

Roadmap

These are on the roadmap and not yet available:

• daho run --watch — hot reload on file changes during development.
• Prebuilt native binaries so run can skip compilation entirely.

Next Steps

• Getting Started — install and write your first server
• Deployment — ship to production with Docker
• Configuration — tune DahoConfig
