Wetland is an enterprise grade object-relational mapper (ORM) for node.js.

Note: This module is under active development. While it's usable and well tested, it's not done yet. Some key features are still missing.

Features

The following is a list of the biggest features this ORM provides. For more detailed information, you can look at the tests until the documentation has been written.

• Unit of work
• Transactions
• Entity manager
• Manager scopes
• Cascade persist
• Deep joins
• Repositories
• QueryBuilder
• Mapping
• MetaData
• Entity proxy
• Collection proxy
• Criteria parser
• More...

Installation

To install wetland simply run the following command:

npm i --save wetland

If you're using typescript, the typings are supplied by default. No additional typings have to be installed.

Usage

Usage will be documented soon. To give you an idea, here's an implementation example:

const Wetland = require('wetland').Wetland;
const Foo     = require('./entity/foo').Foo;
const Bar     = require('./entity/foo').Bar;
const wetland = new Wetland({
  stores: {
    simple: {
      client    : 'mysql',
      connection: {
        user    : 'root',
        database: 'testdatabase'
      }
    }
  },
  entities: [Foo, Bar]
});

// Create the tables. Async process, only here as example.
// use .getSQL() (not async) in stead of apply (async) to get the queries.
let migrator = wetland.getMigrator().create();
migrator.apply().then(() => {});

// Get a manager scope. Call this method for every context (e.g. requests).
let manager = wetland.getManager();

// Get the repository for Foo
let repository = manager.getRepository(Foo);

// Get some results, and join.
repository.find({name: 'cake'}, {joins: ['candles', 'baker', 'baker.address']})
  .then(results => {
    // ...
  });
