Generate Entity Relationship Diagram (Database Schema Visualization)

Idea

• Provide a built-in way to generate an Entity Relationship Diagram from schema.prisma (or directly from the database)
• Make it easy to access for Redwood developers
  • rw erd (ERD = Entity Relationship Diagram)
    • Generates a diagram and opens an image/svg or maybe an interactive webapp
  • in VSCode Redwood: Open Entity Relationship Diagram
    • Same as above, but opens the diagram in the context of VSCode

Why?

• Even the simplest built-in diagram can help us enrich the workflow and tutorials

Implementation?

Ideally, prisma.io should provide this (since we’re treating schema.prisma as our source of truth). Unfortunately, I couldn’t find a concrete solution to this problem (maybe I missed something, @schickling?). Here are two related (open) issues:

• ER diagram from the schema (prisma/prisma#772)
• Visual schema designer (prisma/studio#198)

As @dthyresson pointed out, there is a prisma->DBML generator, which we can then feed to dbdiagram.io. But this isn’t something we can integrate into our tooling since it depends on an online service.

Any ideas/pointers for the implementation are welcome 😃

Can I ask what you used to generate the current diagrams in the documentation? I really like their look.

@noire-munich I think you’ll be interested in seeing the visual graphing tools mentioned in this comment above.
