Not Docker! In the C4 model, a container represents an application or a data store. In many cases, a software system is "owned by" a single software development team. This includes the software system you are modelling, and the other software systems upon which your software system depends (or vice versa). actors, roles, personas, etc).Ī software system is the highest level of abstraction and describes something that delivers value to its users, whether they are human or not. Which in turn are implemented by one or more code elements (classes, interfaces, objects, functions, etc).Īnd people may use the software systems that we build.Ī person represents one of the human users of your software system (e.g. If you’d like to learn more about the Mermaid syntax, head over to the Mermaid website or check out Knut’s first official Mermaid book.In order to create these maps of your code, we first need a common set of abstractions to create a ubiquitous language that we can use to describe the static structure of a software system.Ī software system is made up of one or more containers (applications and data stores),Įach of which contains one or more components, We are very grateful for Knut’s support in bringing this feature to everyone on GitHub. Mermaid has been getting increasingly popular with developers and has a rich community of contributors led by the maintainer Knut Sveidqvist. The net result is fast, easily editable, and vector-based diagrams right in your documentation where you need them. (Here’s the Mermaid code for the diagram.) Here is a visual representation of the path your Mermaid-flavored Markdown takes to become a fully-rendered Mermaid chart. User-supplied content is locked away in an iframe, where it has less potential to cause mischief on the GitHub page that the chart is loaded into.Rendering the charts asynchronously helps eliminate the overhead of potentially rendering several charts before sending the compiled ERB view to the client.It offloads the library to an external service, keeping the JavaScript payload we need to serve from Rails smaller. ![]() Next, assuming the content is viewed in a JavaScript-enabled environment, we inject an iframe into the page, pointing the src attribute to the Viewscreen service. We achieve this through a two-stage process-GitHub’s HTML pipeline and Viewscreen, our internal file rendering service.įirst, we add a filter to the HTML pipeline that looks for raw pre tags with the mermaid language designation and substitutes it with a template that works progressively, such that clients requesting content with embedded Mermaid in a non-JavaScript environment (such as an API request) will see the original Markdown code. When we encounter code blocks marked as mermaid, we generate an iframe that takes the raw Mermaid syntax and passes it to Mermaid.js, turning that code into a diagram in your local browser. The raw code block above will appear as this diagram in the rendered Markdown: Working with Knut and also the wider community at CommonMark, we’ve rolled out a change that will allow you to create graphs inline using Mermaid syntax, for example: Maintained by Knut Sveidqvist, it supports a bunch of different common diagram types for software projects, including flowcharts, UML, Git graphs, user journey diagrams, and even the dreaded Gantt chart. ![]() Mermaid is a JavaScript based diagramming and charting tool that takes Markdown-inspired text definitions and creates diagrams dynamically in the browser. We added support for embedding SVGs recently, but sometimes you want to keep your diagrams up to date with your docs and create something as easily as doing ASCII art, but a lot prettier. A picture tells a thousand words, but up until now the only way to include pictures and diagrams in your Markdown files on GitHub has been to embed an image. ![]()
