MRO

Model Relations to Objects

ORM but in reverse

Reads the schema of relational databases and outputs to objects in JSON or Javascript.

Why

• You want to quickly generate a JSON overview of your database.

• You want to create HTML docs for your database.

• You want to backup your database schema and version them.

• You prefer to define your database with SQL syntax.

• You already have an existing database and don't want to spend additional time remodelling it in your ORM.

• If you aren't sure how to define migrations on certain column types in Knex.js

• If you aren't sure how to model your objects in Objection.js.

• Why not just try it for fun. It's really easy to use.

How to use
