Problem

You need to get a quick and easy overview of your database schema but don't want to...

• Open the source code and find the model definitions
• Start your database and service, install dependencies, have a proper configuration, and open an external tool like TablePlus or DBeaver
• Read through your migrations directory to find the latest version of your schema
• Look through external documentation that might be out of date

Introducing postgres-to-docs!

A Node CLI that renders your schemas as markdown and keeps it up to date! Generates documentation for

• Tables - PKs, FKs, Nullable and Default values
• Views
• User defined types like composites and enums

Future work

• Additional export formats like entity relationship-diagrams
• Materialized views
• Support for watch-mode to rerun the tool on file change

Development

Clone the repo, then:

npm install
npm run start:dev
