c4-component

To create a C4 component diagram, you synthesize code-level documentation into a component-level architecture view. This groups related code into logical components, maps their boundaries, and generates a Mermaid C4Component diagram with supporting structured documentation.

A C4 component diagram visualizes component boundaries, interfaces, dependencies, and relationships inside a single container. You need this component-level architecture view when teams must understand service boundaries and interactions without manually reading implementation files.

You document component boundaries and interfaces by aggregating code-level sources and mapping exposed operations, protocols, and internal relationships. This produces structured documentation covering services, APIs, data access layers, and external systems within a single container.

Yes, you can map dependencies and external systems within a single container using Mermaid C4Component diagrams. The synthesis process documents exposed operations, internal relationships, and external system interactions to maintain a clear component model.

The best way to synthesize implementation files into a maintainable component model is to aggregate c4-code sources into logical components. This defines boundaries, interfaces, and dependencies while producing consistent Mermaid C4 component diagrams and supporting documentation.

Generating C4 component documentation requires analyzing the target codebase to identify component boundaries, interfaces, and dependencies. The synthesis aggregates code-level sources automatically so teams can understand interactions without manually reading every file.
