Template Based Scaffolding for PostgreSQL

• Reverse engineers PostgreSQL database,
• Executes nunjucks templates for each table, schema and for database,
• Makes database objects available to templates using pg-structure.

pg-generator takes your burden of manually creating ORM files or any other files which are based on database structure.

Installation

$ npm install -g pg-generator

Sequelize Example

See sequelize template for usage and details.

$ pgen template sequelize -t sequelize-template
$ pgen exec sequelize-template -d our_crm -u user -p tOpSeCrEt -t model

First command copies one of the builtin templates (sequelize) into target directory (sequelize-template). Second command generates files based on given template (sequelize-template) into target directory (model).

Basic Usage

1. Use pgen template to copy one of the builtin templates or create your own template. (You can use base template for starting up.)
2. Use pgen exec to create files based on your template.

Template

Creating a template from scratch is easy. Execute command below:

$ pgen template base -t my-template

To see a basic example execute following command from shell and examine files in tutorial-example directory.

$ pgen template tutorial -t tutorial-template

For a full fledged example which we use at Fortibase, see Sequelize Example above.

For Low Level Direct Access: pg-structure

If you prefer lower level methods to directly access PostgreSQL structure to build your own generators. You can check pg-structure module which is used to build this module and provides direct access to database structure.
