![]() ![]() With Docker installed, the following shell command will start a Java server on port 8080. What are Notebooks Notebooks are interactive files that allow the mixing of executable code, visualizations, equations, and narrative text. I use a Docker container to run a local PlantUML server. What is Polyglot Programming Polyglot programming is the practice of using multiple programming languages to leverage the strength of each language for different tasks. A generated PNG sequence diagram with a request and a response In this video, you will learn how to use Diagram as Code using Visual Studio Code and PlantUML so that you can store your diagrams with your Source Code. There are a lot of tools to generate diagrams generate PNGs, SVGs and ASCII from plaintext drawings. The same applies to HTML browsers for that matter. That’s why Markdown editors go hand-in-hand with Markdown viewers. Readers should not have to read plaintext diagrams in order to understand a diagram. It is mostly used to create UML diagrams (Unified Modeling Language) from a language called PlantUML, but many other types of images and diagrams can be created. In UML terms, the right-facing arrow represents a synchronous message to ApfelMusic to fetch a playlist, and the dotted left-facing arrow represents a response back. For instance, here’s an example of a server interacting with a music chart service ( View it on PlantUML’s site). In terms of web development, I usually reach for Sequence diagrams to describe message passing within a codebase, and API interactions outside of it. The tool provides ways to draw Sequence, Use Case diagrams, and Class diagrams to name a few. PlantUML is a plaintext way to draw and annotate UML diagrams. Markdown, but for diagrams Bob -> Alice : hello Since it’s just text, it can be checked into version control. Meaning from it even before considering formatting. It’s possible to read the plaintext format and interpret Or expensive and needlessly complex options like OmniGraffle.Īll of those options aside, my favorite way to generate class and sequence diagrams is PlantUML which doesn’t need a user interface, which makes it a lot like the Markdown but for diagrams. ![]() To enumerate a few, there’s free options like and miro, In my endless Google searches, there are a ton of ways to generate diagrams. Diagrams are a way to explain code concepts that words alone cannot convey. ![]()
