sequelize-data-dictionary v1.0.1

sequelize-data-dictionary

A library for working with data dictionaries in Sequelize, an Object-Relational Mapping (ORM) library for Node.js and PostgreSQL, MySQL, SQLite, and Microsoft SQL Server.

Installation

npm install sequelize-data-dictionary

Usage

const Sequelize = require('sequelize');
const DataDictionaryGenerator = require('sequelize-data-dictionary');

const sequelize = new Sequelize('sqlite::memory:');
const dataDictionaryGenerator = new DataDictionaryGenerator(sequelize, { format: 'json' });

The DataDictionaryGenerator constructor accepts an optional options object, where you can specify the desired output format for the data dictionary. The supported formats are json (default), yaml, and markdown.

Then, you can use the generateDataDictionary method to generate the data dictionary:

async function generateDataDictionary() {
  const dataDictionary = await dataDictionaryGenerator.generateDataDictionary();
  console.log(dataDictionary);
}

generateDataDictionary();

This will generate a data dictionary for the specified database and log it to the console in the specified format.
