Database connection wrapping Mongoose (for MongoDB)

This module connects to mongoDB using Mongoose default connection.

To use this module

1. Import module
   const nodeMongo =require('kth-node-mongo')

2. Connect to mongoDB over SSL: nodeMongo.connect(options, sslOptions) or

3. Connect to mongoDB without SSL: nodeMongo.connect(options)

4. Use Mongoose schema and model to interact with mongoDB

Function connect() returns a promise to be resolved upon completed connection or rejected on error.

• dbUsername (required) Credentials, the database user

• dbPassword (required) Credentials, the password for the database user

• dbUri (required) The URI for the mongoDb to connect to

• logger (optional) A logger to use, defaults to stdout(console.log)

• reconnectTries (optional) Max attempts to reconnect to mongoDB if connection is lost, defaults to 1000

• reconnectInterval (optional) Time between reconnect attempts in milliseconds, defaults to 30000

• ssl (optional) Boolean flag if database connection shoold be encrypted or not

• authDatabase (optional) If login credentials are used, specifies which database to use for authentication of user. Can also be sent as part of dbUri.

• caCerts (optional) A list of buffers or strings containing the ca certificates (.pem) we accept when setting up the secure connetion.

Example without secure database connction

nodeMongo.connect({
  dbUsername: 'user',
  dbPassword: 'himligt',
  dbUri: 'mongodb://localhost/le_database?authSource=authDB',
  logger: log
})
.then(() => log.debug('Connected to Mongo'))
.catch((err) => log.error(err))

Example with secure database connction

nodeMongo.connect({
  dbUsername: 'user',
  dbPassword: 'himligt',
  dbUri: 'mongodb://localhost/le_database',
  logger: log
},
{
  ssl: true,
  authenticationDatabase: 'authDB',
  sslCA: certs
})
.then(() => log.debug('Connected to Mongo'))
.catch((err) => log.error(err))

1. Import module
   const nodeMongo =require('kth-node-mongo')

2. Check connection: if (nodeMongo.isOk()) { // OK } else { // ERROR }
