uranio v0.1.54

Uranio

Uranio is the lightest Typescript Object Document Mapper (ODM) for MongoDB and Object Relational Mapping (ORM) for MySQL.\ It creates a client for querying collections/tabls in a database by just parsing the types in a repository.

It is the simplest and fastest way to query a database without the need to build a Data Access Layer (DAL) from the defined types.

Install

yarn add uranio

How it works

Run:

uranio generate -d mongodb
// or
uranio generate -d mysql

The above command search for all interfaces in your repository that extends the uranio.atom interface.\ For each of these interfaces it creates a method to query a collection with a name of the interface.

For example if in your code you have:

import uranio from 'uranio';

interface Product extends uranio.atom {
  title: string;
  description: string;
  price: number;
}

then Uranio generates a method for querying a collection named products:

import uranio from 'uranio';

const uri = process.env.MONGO_DATABASE_URI || '';
const db_name = process.env.MONGO_DATABASE_NAME || '';

const urn = uranio.MongoDBClient({uri, db_name});

// Get all products
const products = await urn.products.get_atoms({});

// Create a product
await urn.products.put_atom({
  title: 'Uranio mug',
  description: 'A radioactive mug for your coding breakfast',
  price: 4.99
});

Primary index _id for MongoDB

When extending an interface with uranio.atom (MongoDB) this add a primary index attribute _id to the interface, so there is no need to add it manually.

import uranio from 'uranio';

interface Product extends uranio.atom {
  title: string;
  description: string;
  price: number;
}
// It resolves in:
// {
//  _id: string;
//  title: string;
//  description: string;
//  price: number;
// }
