![]() ![]() The C4 model is pretty easy to use, so start designing your software in a way that you can share your design with others. The full example is available in this github repo. Zooming in the page does not zoom in the iframe rendering the svg.Īll in all, its a wonderful way to start documenting simple software architectures. Since the click event is on the A node inside the subgraph, we have to be sure to click on it, rather than on the subgraph itself.įor large models, github seems not to have a way of scaling it up so that the text and other objects are visible. The same is done for opening a component diagram from a container diagram. This means that if this repo is forked, then the path has to be editted to reflect its new location. It seems that we cannot supply a path relative to our repo yet. The url supplied has to be either absolute pointing to the container diagram, or relative to ' '. That is why we use A3 instead of booksSystem. The click event does not work with subgraphs. Include a code section with mermaid as the language:Įnter fullscreen mode Exit fullscreen mode We are going to show how to build simple models using mermaid JS, with an example available at mermaid-c4-model Each lower level diagram 'zoom in' on a concept. A C4 model for a given system is composed of 4 diagrams, representing 4 different levels of abstraction. MermaidJs, which is free and can be used in github markdown files. The C4 model is an 'abstraction-first' approach to diagramming software architecture, based upon abstractions that reflect how software architects and developers think about and build software.structurizr which is proprietary software from Simon Brown, the developer of the C4 model.goadesign for creating software architecture models and diagrams in Go.C4-plantuml which provides a VS-Code extension.There are not that many tools that are able to work with C4 models yet, these being limited to: To be able to visualize C4 models, we have to have a system that is able to take us from one item up in the hierarchy to its children down the hierarchy. Good software architecture diagrams assist with communication inside/outside of software development/product teams, efficient onboarding of new staff, architecture reviews/evaluations, risk identification (e.g. More information is made available as we go down the hierarchy, more like zooming into a map. The C4 model is an easy to learn, developer friendly approach to software architecture diagramming. Container Diagram showing the independently deployable parts of the sytem.The C4 model consists of hierarchical diagrams in 4 steps: For more information about the C4 model, please visit its website. The C4 model is an "abstraction-first" approach to diagramming software architecture, based upon abstractions that reflect how software architects and developers think about and build software. But it has an alternative in thee C4 model. UML is a popular standard for developing software architecture.
