hapi-plugin-mysql-promise

hapi plugin for MySQL

based on hapi-plugin-mysql using mysql2 and promises. As a side effect, this also supports JSON fields.

What

Attaches a MySQL connection from a pool to every request. We are using mysql2/promise here to provide promisified version of the mysql connection.

How

Via request.app.db. You can also manually get a connection from the server via server.getDb(function (err, connection) {}).

server.register({
    register: require('hapi-plugin-mysql'),
    options: {
        host: "localhost",
        user: "root",
        password: ""
    }
}, function (err) {

    if (err) console.log(err);
    ...
});

server.route({
    method: 'GET',
    path: '/',
    handler: function (request, reply) {

        request.app.db.query(...)
            .then((result) => reply(result))
            .catch((err) => reply(err));
    }
});

The options are the same options you can pass onto the mysql2 lib for making a connection. See https://www.npmjs.com/package/mysql2 for more info on the mysql2 lib itself.

The keyword db is used because connection is used by hapi and might cause confusion/collision.

If you want more manual control or you want to use the same pool outside of the hapi part of your server you can initialize the pool before the plugin registration by calling require('hapi-plugin-mysql-promise').init(options, callback) and then call require('hapi-plugin-mysql-promise').getConnection to get a connection from the pool. If you still want to register the plugin (to get all the goodies) just don't pass any options to the plugin registration and it will use the same pool as first created. To manually stop the pool call require('hapi-plugin-mysql-promise').stop. See the tests for more granular use cases.

Catches

• The releasing of the connection is handled on the tail event of the server. If you have handlers that reply early, with reply.file() for example, be sure to register a tail event and use that as callback.
• Transactions are no longer a part of this plugin and should be handled (with care) in your code

Testing

• 100% code coverage!
• See .travis.yml and the tests for more info.
