manydb v0.1.2

manydb

Lightweight multi-idiom database API for Node.js.

Install

Install ManyDB:

yarn add manydb

// or

npm install manydb

Then install the package for your desired database (choose one):

yarn add pg     # PostgreSQL
yarn add mysql  # MySQL

It is possible to use multiple different database types, but in most cases only one should be used in order to minimize dependencies.

Usage

To use ManyDB, create a database with a config object and connect to it. You can then run queries on the database like normal.

ManyDB currently supports MySQL and PostgreSQL.

Example

import { createDb, POSTGRES } from manydb;

// Create and initialize database
const db = createDb({
  type: POSTGRES,
  user: 'myuser',
  password: 'pass', // optional
  host: 'localhost',
  database: 'my_db'
});

// Connect to database
db.connect()
  .then(() => {
    // ...
  })
  .catch(err => {
    // ...
  });

// Query
db.query('SELECT * FROM products')
  .then(result => {
    // ...
  })
  .catch(err => {
    // ...
  });

Creating a database

You can create a database using the provided createDb function.

Pass in a config object specifying the database details.

// Create and initialize database
const db = createDb({
  type: POSTGRES,
  user: 'myuser',
  password: 'pass', // optional
  host: 'localhost',
  database: 'my_db'
});

Connection

You have to connect to the database before using it. Doing this is as simple as:

// Connect
db.connect()
  .then(() => {
    // ...
  })
  .catch(err => {
    // ...
  });

// Disconnect (only if needed)
db.disconnect()
  .then(() => {
    // ...
  })
  .catch(err => {
    // ...
  });

Query

Query the database.

// Query
db.query('SELECT * FROM products')
  .then(result => {
    // ...
  })
  .catch(err => {
    // ...
  });
