Mongo Memory

Bootstrap programmatically Mongodb for testing or mocking during development.

Works on all platforms which is due to the awesome mongodb-prebuilt package.

Installation

npm install mongo-memory

Usage

const MongoInMemory = require('mongo-memory')

const port = 8000
const dbPath = "./tempb/.data" // Mongodb placed some metadata
const mongoServerInstance = new MongoMemory(port, dbPath)

mongoServerInstance.start().then(server) => {

    mongoServerInstance.getMongouri('myDatabaseName')
    mongoServerInstance.getCollection('coll1')
    mongoServerInstance.getDocument('myDatabaseName', 'coll1', "<id>")
    mongoServerInstance.addDocument('myDatabaseName', 'coll1', { a: 1, b: 2 })
    mongoServerInstance.addDirectoryOfCollections('myDatabaseName', '<path>')

})

mongoServerInstance.stop()

Background

Mongodb storageEngine ephemeralForTest is used. The connection is created by the official mongodb package.

Credits

Most code was copied from mongo-in-memory but with significant improvements:

Changes:

• Don't save metadata in node_modules
• Don't generate random folders
• Clean up of metadata must be handled by user
• 100% Promise API
• Update mongodb-prebuilt to the newest version
• Update dependencies and tests
• Gracefully shutdown Mongodb when execute stop
• Create recursively databasePath
