mongolab-data-api
is a node.js module designed to allow you to access mLab's Data API with minimal overhead.
I designed mongolab-data-api so the only documentation you need, in addition to the Data API specification, is how to install node, how to install the module, and how to make a call.
Using npm:
$ npm install --save mongolab-data-api
If you don't have or don't want to use npm:
$ cd ~/.node_modules
$ git clone git://github.com/gmontalvoriv/mongolab-data-api.git
To require the library and initialize it with your account API key:
var mLab = require('mongolab-data-api')('<Your Api Key Here>');
List databases
mLab.listDatabases(function (err, data) {
if (err) { console.log(err); }
else {
console.log(data); // => [db1, db2, db3, ...]
}
});
List collections
mLab.listCollections('exampledb', function (err, collections) {
console.log(collections); // => [coll1, coll2, ...]
});
List documents
var options = {
database: 'exampledb',
collectionName: 'examples',
query: '{ "key": "value" }'
};
mLab.listDocuments(options, function (err, data) {
console.log(data); //=> [ { _id: 1234, ... } ]
});

- Creating a new collection
- As soon as you POST your first document you should see the collection appear
- 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
- mLab account w/API key.
- node.js v4.2.6+ (4.2.6 is the version I used to develop this module. I'm unsure if it will work with previous ones. If you run a previous version, and it works, let me know and I'll update this)
- xmlhttprequest 1.8.0+
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
If you run into problems, have questions, or whatever else you can open an issue on this repository, or tweet me @gmontalvoriv. If you'd like to submit a patch, shoot me a pull request. I'd like to keep this module simple, so if you want to add all kinds of crazy functionality - you might want to fork. When in doubt, send a pull request - the worst that can happen is that I won't merge it.
