@domainlang/cli

Validate, query, and manage DomainLang models from the terminal. Built for local development and CI pipelines that treat architecture decisions as code.

Install

npm install -g @domainlang/cli

Or run directly with npx:

npx @domainlang/cli validate

Get started

# Scaffold a new DomainLang workspace
dlang init

# Validate the current directory
dlang validate

# Query all bounded contexts
dlang query bcs

Commands

| Command | What it does | | --- | --- | | dlang init [directory] | Scaffold starter files for a new workspace | | dlang validate [path] | Validate a single file or an entire workspace | | dlang query <type> [path] | Query domains, bounded contexts, teams, relationships, and more | | dlang install | Install dependencies declared in your manifest | | dlang add <specifier> | Add a model dependency | | dlang remove <name> | Remove a model dependency | | dlang update | Refresh dependency state from the lock file | | dlang upgrade [package] [version] | Upgrade one or all dependencies to the latest version | | dlang outdated | List dependencies with newer versions available | | dlang cache-clear | Clear the local dependency cache | | dlang help | Show available commands |

Use it in CI

Every command supports --json, --quiet, and --no-color for scripted environments.

A minimal CI step:

dlang validate --json

This exits non-zero on validation errors and writes structured JSON to stdout, so you can parse results downstream or simply treat it as a gate.

Typical workflow

dlang install           # Resolve and lock dependencies
dlang validate          # Check for errors
dlang query bcs --classification Core   # Inspect your Core contexts
