hapi-mongoose2

Mongoose plugin for hapi-based servers. Supports connecting to one or multiple databases and look up and register models by connection. The plugin options are:

• options - a connection or an array of connections where:
  • connection - an object containing:
    • uri - a mongo uri string
    • alias - (optional) a database name alias used to namespace connections when multiple are created. otherwise ignored.
    • loadSchemasFrom - (optional) one of:
      • An array of globs from where schemas will be loaded. matching files must export a mongoose.Schema object or a function with the signature async function(server) returning a schema.
      • An object containing Mongoose.Schema elements.
    • options - (optional) options passed to mongoose createConnection method. unknown properties are allowed:
      • auth - an object with auth credentials
        • user
        • password
      • autoIndex
      • bufferCommands
  • connections - an array of connection objects as described above.
  • decorations - (optional) an array of interfaces to be decorated using server.decorate method. allowed values are server, request.

Connection and models are accessible under the server.app.mongo property. When multiple connections are created the database name or alias is used as namespace for accessing each database properties. Same applies for decorated interfaces.

Models are named as the filename matching the schema pattern. Model name first letter is capitalized by default. e.g. Animal.

Example

const plugin = {
    plugin: require('hapi-mongoose2'),
    options: {
        connections: [
            {
                uri: 'mongodb://localhost:27017/myapp'
            },
            {
                alias: 'safebox',
                uri: 'mongodb://localhost:27017/secrets',
                loadSchemasFrom: [
                    'src/schemas',
                    '!.{md,json}'
                ],
                options: {
                    auth: {
                        user: 'admin',
                        password: 'pa55w0rd'
                    },
                    autoIndex: false,
                    bufferCommands: true
                }
            }
        ],
        decorations: ['request', 'server']
    }
};
 
const server = new Hapi.server();
await server.register(plugin);
 
// Using database `secrets` from:
// 1 - `server.app` object
// 2 - `request` decorated object
// 3 - `server` decorated object
 
const { Admin } = server.app.mongo.safebox.models;
await Admin.create({ name: 'Quentin', last: 'Tarantino' });
 
server.route({
    method: 'GET',
    path: '/',
    handler: function (request) {
        const { Admin } = request.mongo.safebox.models;
        return Admin.findOne({ name: 'Quentin' }).exec();
    }
});
 
await server.mongo.safebox.connection.close();

mongoose needs to be installed alongside this plugin in order to work.
