Mermaid for easy schemas
· 2 min read
Schemas configured as code
As the saying goes, an image is worth a thousand words...
Whenever I tried to create schema before, I always had trouble keeping it up-to-date and had to drop it :(
But no longer thanks to Mermaid !
What is Mermaid ?
Mermaid is a language to create schmas.
No long are you stuck editing PNGs !
You can access the online tool here. And the project's GitHub here.
What's even better, mmd (mermaid markdown) is supported in GitHub Readme !
it's unfortunatly not supported by Docusaurus :(
Example
And here is the associated code, that you can copy paste and easily edit!
