Auto Development Server

Automatically detects and starts development servers for various project types when the workspace starts. Supports Node.js, Python, Ruby, Go, Rust, PHP projects, and integrates with devcontainer.json configuration.

module "auto_dev_server" {
  count    = data.coder_workspace.me.start_count
  source   = "registry.coder.com/kunstewi/auto-dev-server/coder"
  version  = "1.0.0"
  agent_id = coder_agent.example.id
}

Supported Project Types

• Node.js: Detects package.json and runs npm start, npm run dev, or yarn start
• Python: Detects Django (manage.py), Flask, or FastAPI projects
• Ruby: Detects Rails applications and Rack applications
• Go: Detects go.mod or main.go files
• Rust: Detects Cargo.toml files
• PHP: Detects composer.json or index.php files
• Devcontainer: Uses postStartCommand from .devcontainer/devcontainer.json
