Component model

Studio Component Model

The App Framework Template Studio is the templating and update-management layer behind the component system described in these docs. It solves two core problems:

  1. Maintenance at scale — A bug fix to five foundation application templates with 100 applications per template means the fix needs to reach 500 cloned applications. Manual propagation does not scale.
  2. Template creation speed — There is value in standing up the latest AI blueprint on DataRobot quickly. You need good building blocks.

Components are copier-style templates. Each is a top-level folder or file set that you can add to your recipe. The answers you give during template application are recorded in .datarobot/ as YAML, enabling future automated updates at the component-instance level.

Global components

These appear once per application template:

Component Repository Description
Base af-component-base Pulumi project, task runner, .datarobot/ configuration, CI/CD scaffolding, LICENSE, CODEOWNERS.
LLM af-component-llm LLM Gateway or external model integration via the DataRobot LLM Deployment.

One-to-many components

These can be applied multiple times as you build out the template:

Component Repository Description
FastAPI Backend af-component-fastapi-backend Local development tasks, FastAPI API documentation, and Pulumi configuration for Custom Application deployment.
React Frontend af-component-react Development server, API proxy, static asset build, and prebuilt tests.
Agent af-component-agent CrewAI, LangGraph, LlamaIndex, or YAML-based NeMo Agent Toolkit.
DataRobot MCP af-component-datarobot-mcp FastMCP server with DataRobot predictive tools and third-party integrations.

Technical underpinnings

It's all built on top of Copier. Similar to Yeoman or Cookiecutter, but with Git semantics that make updates after you copy the template baked into the box.

Update model

Copier Update

The App Framework uses copier and git fork semantics to keep things updated.
