ACTIVE RECORD JS

A library responsible for representing business data.

This library follows the Active Record Pattern by building a wrapper on top of popular orm such as Mongoose and Sequelize to support all kinds of databases

⚙️ How to use the package in project

1. You should create the following environment variables in your node project.

RDBMS_DATABASE_URI="mysql://DATBASE_USER:DATABASE_PASSWORD@DATABASE_HOST:DATABASE_PORT/DATABASE_DB"
NOSQL_DATABASE_URI="mongodb://DATABASE_HOST:DATABASE_PORT/DATABASE_DB"
NOSQL_DATABASE_ADAPTER="mongodb"

2. Once the variables have been set. You should create a model base on the active record SchemaProperty. See example below

import { ActiveRecord } from "@fractalerp/active-record-js"

export interface ITaskModelDocument {
  name: string;
  description: string;
}

const TaskModelSchema = {
  name: {
    type: String,
    required: true,
    unique: true
  },
  description: {
    type: String,
    default: null
  }
};

export const TaskModel = new ActiveRecord<ITaskModelDocument>("Task", TaskModelSchema);

3. Then use its methods to perform data management. The following methods are supported;

Method	Description
find	returns list of data objects
findOne	returns one data item
create	save item to the data store
update	updates the record in the store
delete	delete item from the data store

Since we support all kinds of databases. The following are the respective methods of the two kinds of databases.

This only applies to NOSQL databases

Method	Description
aggregate	peform aggregate action based on a pipeline
index	create an index in the document store

This only applies to Relational databases

Method	Description
query	create a raw SQL to send to database
beginTransaction	start a transaction
commitTransaction	persist a transaction
rollbackTransaction	rollback a transaction

Other than that, all the other ORM respective methods for Sequelize and Mongoose are supported by default.

4. Finally you can use the model to peform data action. See example.

// create task
const task = await TaskModel.create({
    name: 'Use fractalerp active record js',
    description: 'Change all models'
});

// Find one task
const task = await TaskModel.findOne({ id: 'cbdabs-29232323-msasd'});

5. You can also use the underlying ORM model and instance methods

// create task
const filter = { };
const countTasks = await TaskModel.model.countDocuments(filter);

Scripts

While developing, you will probably rely mostly on npm start; however, there are additional scripts at your disposal:

npm run <script>	Description
start	Build the project and monitor source and config for changes and rebuild. Start the dev server
watch	Build the project and monitor source and config for changes and rebuild.
emit	Output javascript code
test	Runs lint, build, unit tests with mocha and generates a coverage report
test:dev	Runs mocha and watches for changes to re-run tests; does not generate coverage reports.
test:unit	Runs unit tests with mocha and generates a coverage report.
build:release	Build app optimized for production
build:development	Build app optimized for debugging.
lint	Lint all .js files.
lint:fix	Lint and fix all .ts files.
