mlab-promise v0.0.6

mlab-promise

mlab-promise is a node.js module designed to allow you to access mLab's Data API with minimal overhead.

I don't intend to remove the old functions, but I added new cache functions which can be disabled. It effectively polls the database and loads all your information so that there's no wait between each function. mlab-promise has all the documentation that you'd need to access your mlab database. Also, this module and this documentation is based off of mongolab-data-api by gamontal. Their version is no longer being maintained and purely synchronous. If you need a something like that, be sure to check it out their version.

Major change

• All old functions except for runCommand and updateDocuments can now be run normally but will return with cached values for improved performance
• Cacheing values has yet to be properly documented, however it is much faster and uses much less requests, despite it's startup time of a few seconds
• Cacheing requires discord.js to also be installed, because the Maps that are written to are Collections

Installation

Using npm:

$ npm install mlab-promise

If you don't have or don't want to use npm:

$ cd ~/.node_modules
$ git clone git://github.com/Logos-King/mlab-promise.git

Usage

To require the library and initialize it with your account API key:

let mlabInteractor = require('mlab-promise')
let mLab = new mlabInteractor('<Your Api Key Here>', "<whether-to-cache>[boolean: true or false]",[ignore='databasenametonotcache']);

Examples

List databases

mlab.on('ready', () => {
    console.log(mlab.databases.map(database => database.name)) // => [db1, db2, db3, ...]
})

mLab.listDatabases()
    .then(databases => {
        console.log(data); // => [db1, db2, db3, ...]
    });

List collections

mlab.on('ready', () => {
    console.log(mlab.databases.get('exampledb').collections.map(collection => collection.name))  // => [coll1, coll2, ...]
})

mLab.listCollections('exampledb')
    .then(collections => {
        console.log(collections); // => [coll1, coll2, ...]
    });

List documents

mlab.on('ready', () => {
    console.log(mlab.databases.get('exampledb').collections.get('examples').documents.map(document => document.data))  //=> [ { _id: 1234, ...  } ]
})

var opt = {
    database: 'exampledb',
    collectionName: 'examples',
    query: '{ "key": "value" }'
};

mLab.listDocuments(options)
    .then(console.log)

• runCommands
  • Only certain MongoDB commands are exposed through the Data API

  • The available commands are:

    • getLastError
    • getPrevError
    • ping
    • profile
    • repairDatabase
    • resetError
    • whatsmyuri
    • convertToCapped
    • distinct
    • findAndModify
    • geoNear
    • reIndex
    • collStats
    • dbStats

Requirements

• mlab-promise
• mLab account w/API key.
• node.js v12.16.3+ (This module was made in this version)

Disclaimer

From the official mLab Data API documentation:

mLab databases can be accessed by your application code in two ways. The first method - the one we strongly recommend - is to connect using one of the MongoDB drivers (as described above). You do not need to use our API if you use the driver. In fact, using a driver provides better performance, better security, and more functionality.

The second method is to connect via mLab’s RESTful Data API. Use this method only if you cannot connect using a MongoDB driver.

Visit mLab's official documentation if you have any security concerns about using the Data API
