postgerd v1.0.7

PostgERD

"Show me your flowchart and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won't usually need your flowchart; it'll be obvious." - Fred Brooks, The Mythical Man-Month

PostgERD connects to your postgres database with environment variable credentials (using dotenv if needed) and generates an ERD svg from what it finds there. Can also output PlantUML or nomnoml. Supports multiple db schemas.

Note: Foreign key connections across schemas are only supported in the PlantUML output.

Installation

To install:

npm install --save-dev postgerd

Also make sure you have postgres connection environment variables set (that is, either DATABASE_URL or PGUSER,PGPASSWORD,PGHOST, and PGDATABASE).

To output an svg:

npx postgerd -o myOutput.svg

To restrict it to a single schema in the database

npx postgerd -o myOutput.svg --schema my_schema

To output a plantuml file:

npx postgerd -o myOutput.plantuml --plantuml

To output a nomnoml file:

npx postgerd -o myOutput.nomnoml --nomnoml
