And this approach is important if you plan to generate diagrams with sensitive information. Running PlantUML server locallyĪlthough you can render PlantUML diagrams online it’s better for usability and security reasons to install a local server. For example, this link opens the PlantUML Server with a simple Authentication activity diagram.

The whole diagram is compressed into the URL itself and diagram data is stored in PNG metadata, so you can fetch it even from a downloaded image. There’s an online demo server which you can use to view PlantUML diagrams. PlantUML in VS Code with Markdown Preview Enhanced To preview a PlantUML diagram in VS Code with Markdown Preview Enhanced press Cmd-P to open Command palette and select Markdown Preview Enhanced: Open Preview An alternative option is to use the plantuml plugin.

PlantUML is used to draw UML diagrams, using a simple and human readable text description node_modules/.bin/mmdc -i $mmd -o $.pngĪlternatively you can use node_modules/mermaid/bin/mermaid.js where mmd is the mermaid file. If you have plenty of defition files you can use the following script to generate PNGs: #!/usr/bin/env bash node_modules/.bin/mmdc -i input.mmd -o output.png Install mermaid.cli locally: npm install mermaid.cli You can use the mermaid.cli tool which takes a mermaid definition file as input and generates a svg/png/pdf file as output.

Some of the tools for drawing diagrams with human readable text are mermaid and PlantUML. And then there’s the problem of which tools to use. Writing documentation is a task that no one really likes especially when diagrams and flowcharts are involved.
