Mongo Lux

A thin wrapper :package: to MongoDB node.js driver using ES6.

No schema, no magic, just plain objects{} and array of objects[{}...]

Prefer node.js version 8 onwards

Supported node.js frameworks

• express.js
• connect

Installation

npm install mongolux

Bootstrapping your application

const { bootstrap, db } = require('mongolux');
....

await bootstrap(require('./path/to/config/database'));

Create your config file (database.js is just a filename)

This is what your database.js file should look like

module.exports = {
  database1: {
    uri: 'mongodb://127.0.0.1:4000/?retryWrites=true',
    db: 'db1',
    useNewUrlParser: true,
    poolSize: 5,
    ssl: false,
    sslValidate: true,
    sslCA: null,
    sslCert: null,
    sslKey: null,
    sslPass: null,
    autoReconnect: true,
    noDelay: true,
    keepAlive: 30000,
    connectTimeoutMS: 30000,
    socketTimeoutMS: 360000,
    reconnectTries: 30,
    reconnectInterval: 1000,
    ha: true,
    haInterval: 10000,
    replicaSet: null,
    secondaryAcceptableLatencyMS: 15,
    acceptableLatencyMS: 15,
    connectWithNoPrimary: false,
    authSource: null,
    w: null,
    wtimeout: null,
    j: false,
    forceServerObjectId: false,
    serializeFunctions: false,
    ignoreUndefined: false,
    raw: false,
    promoteLongs: true,
    promoteBuffers: false,
    promoteValues: true,
    domainsEnabled: false,
    bufferMaxEntries: -1,
    readPreference: null,
    pkFactory: null,
    promiseLibrary: null,
    readConcern: null,
    maxStalenessSeconds: null,
    appname: null,
    loggerLevel: null,
    logger: null,
  },
  database2: {
    uri: 'mongodb://127.0.0.1:4001/?retryWrites=true',
    db: 'db2',
    useNewUrlParser: true,
    poolSize: 5,
    ssl: false,
    sslValidate: true,
    sslCA: null,
    sslCert: null,
    sslKey: null,
    sslPass: null,
    autoReconnect: true,
    noDelay: true,
    keepAlive: 30000,
    connectTimeoutMS: 30000,
    socketTimeoutMS: 360000,
    reconnectTries: 30,
    reconnectInterval: 1000,
    ha: true,
    haInterval: 10000,
    replicaSet: null,
    secondaryAcceptableLatencyMS: 15,
    acceptableLatencyMS: 15,
    connectWithNoPrimary: false,
    authSource: null,
    w: null,
    wtimeout: null,
    j: false,
    forceServerObjectId: false,
    serializeFunctions: false,
    ignoreUndefined: false,
    raw: false,
    promoteLongs: true,
    promoteBuffers: false,
    promoteValues: true,
    domainsEnabled: false,
    bufferMaxEntries: -1,
    readPreference: null,
    pkFactory: null,
    promiseLibrary: null,
    readConcern: null,
    maxStalenessSeconds: null,
    appname: null,
    loggerLevel: null,
    logger: null,
  },
}

All options passed to MongoClient is supported except for db (mongolux uses this internally)

Querying your MongoDB database

const { db } = require('mongolux');

...

const users = await db('database1').collection('users').find({}).toArray();

.collection('users').find({}).toArray();

Seems familiar? Well, those are just functions from the MongoDB node.js driver API. Everything is exactly that because we just wrapped the mongodb package.

Binding listeners for each database connection

db().forEach((conn, name) => {
  conn.on('close', () => console.log(`Disconnected from mongolux ${name}...`))
  conn.on('reconnect', () => console.log(`Reconnected from mongolux ${name}...`))
})

I use this on my site. If you need any help, please file an issue @Github
