Flux Capacitor - Sequelize Database Bindings

Database bindings for the Flux Capacitor. Uses Sequelize ORM to connect to PostgreSQL, MySQL, SQLite and MSSQL databases.

Usage

Here comes some sample code showing how to connect to a database, set up a simple data model and create a flux capacitor store using it:

// Import the database-agnostic core library:
const { aggregateReducers, createStore, eventLogReducer } = require('flux-capacitor')
// Import the database-backend:
const { connectTo } = require('flux-capacitor-sequelize')
const createEventModel = require('flux-capacitor-sequelize').createEventModel
 
const Sequelize = require('sequelize')
 
async function setUpStore () {
  // Connect to database
  const database = await connectTo('postgres://user:[e-mail]:5432/dbname', createCollections)
  // Use the default event log reducer (event persistence is done by a simple reducer as well)
  const rootReducer = aggregateReducers(reducer, eventLogReducer)
  // Create store
  return await createStore(rootReducer, database)
}
 
function createCollections (sequelize, createCollection) {
  return [
    createCollection('Events', createEventModel(sequelize)),
    createCollection('Issues', createIssueModel(sequelize))
  ]
}
 
function createIssueModel (sequelize) {
  return sequelize.define('Issue', {
    id: { type: Sequelize.UUID, primaryKey: true },
    title: { type: Sequelize.STRING, allowNull: false },
    content: { type: Sequelize.TEXT },
  })
}
