Detect schema format

You can instantly generate an ER diagram by appending a GitHub file URL to liambx.com/erd/p/. For example:

https://liambx.com/erd/p/github.com/mastodon/mastodon/blob/main/db/schema.rb

When Liam ERD fetches your schema file, it automatically attempts to determine the schema format. Here’s how the detection works:

• File name check: Certain filenames like schema.rb or Schemafile are assumed to be schemarb.
• File extension check: Files ending with .rb are treated as schemarb, while files ending with .sql are treated as postgresql.
• For more details, refer to the detectFormat.ts file in our GitHub repository.

Override the Detected Format

If the automatic detection doesn’t match your desired format, you can specify it manually via query parameters. For example:

https://liambx.com/erd/p/example?format=schemarb

Check /docs/supported-format for a full list of valid format identifiers.
