Hapi-MongoDB-promises

This is a mongo db connection plugin and a promise wrapper for the mongo API. It enables your Hapi application to connect to mongodb and run queries.

It takes 2 options :

• url: MongoDB connection string (eg. mongodb://user:pass@localhost:27017),

• settings: Optional. Provide extra settings to the connection, see documentation.

Several functions are exposed by this plugin :

• find(collection, query) : Returns a promise that resolves with the array of items matched.
• findOne(collection, query) : Returns a promise that resolves with the item matched.
• findOneById(collection, id) : Returns a promise that resolves with the item matched.
  • Autowraps the id in a ObjectId if not already done so.
• insert(collection, document) : Returns a promise that resolves with the array of items added.
• insertOne(collection, document) : Returns a promise that resolves with the first item added.
• update(collection, query, update, options) - Returns a promise that resolves with the result of the query
• remove(collection, query) - Returns a promise that resolves with the result of the query

This plugin also exposes some objects :

• db : connection object to the database, if you need to run queries not available via the wrapper.

Install:

    npm install hapi-mongodb-promises --save

Usage example :

var Hapi = require("hapi");

var dbOpts = {
    "url": "mongodb://localhost:27017/test"
};

var server = new Hapi.Server(8080);

server.pack.register({
    plugin: require('hapi-mongodb-promises'),
    options: dbOpts
}, function (err) {
    if (err) {
        console.error(err);
        throw err;
    }
});

server.route( {
    "method"  : "GET",
    "path"    : "/users/{id}",
    "handler" : usersHandler
});

function usersHandler(request, reply) {
    var mongo = request.server.plugins['hapi-mongodb-promises'];
    mongo
        .findOneById('users', request.params.id)
        .then(reply)
        .otherwise(function (err) {
            reply(Hapi.error.internal('Internal MongoDB error', err));
        });
};

server.start(function() {
    console.log("Server started at " + server.info.uri);
});
