Sengi-MongoDB

A wrapper for Mongo DB that implements the Sengi document store interface.

Installation

npm install sengi-mongodb

Usage

To instantiate a MongoDbDocStore you have to provide the following parameters:

• mongoUrl - A url that identifies your Mongo DB instance.

• mongoOptions - An object that describes how to connect to mongo. This is passed directly to the MongoClient constructor. See the example below for connecting with a username and password.

• config - A configuration object

  • getDatabaseName - A function (docTypeName, docTypePluralName, options) that returns the name of the database to connect to.

  • getCollectionName - A function getCollectionName (databaseName, docTypeName, docTypePluralName, options) that returns the name of the collection to edit.

const { createMongoDbDocStore } = require('sengi-mongodb')

const mongoDbDocStore = createMongoDbDocStore(
  'mongodb://database.server...',
  {
    auth: { user: 'sengi', password: 'sengi' },
    useUnifiedTopology: true
  },
  {
    getDatabaseName: (docTypeName, docTypePluralName, options) => 'myDatabaseName',
    getCollectionName: (databaseName, docTypeName, docTypePluralName, options) => docTypePluralName
  }
)

mongoDbDocStore.connect()
.then(() => {
  mongoDbDocStore.upsert('test', 'tests', {
    id: '0001',
    docType: 'test',
    docOps: [],
    hello: 'world'
  })
})

Setup

To run the tests locally you will need MongoDB running locally:

• Listening at https://127.0.0.1:27017
• With an admin/root user named sengi and with password sengi.
• The database sengi and collection trees, that are used by the automated tests, will be created automatically.

You can set mongo running on your local machine by running the following docker command:

docker run -d --name test-mongo-with-sengi -p 127.0.0.1:27017:27017 \
    -e MONGO_INITDB_ROOT_USERNAME=sengi \
    -e MONGO_INITDB_ROOT_PASSWORD=sengi \
    mongo:4.2.9

You can use the usual docker comands to start and stop the instance.

docker ps -a
docker stop <first-4-characters>
docker rm <first-4-characters>

You can connect to the server by using the Mongo SH client (mongosh).

mongosh mongodb://127.0.0.1:27017 -u sengi -p sengi

You can issue the following commands, using Mongo SH client, to work with databases and collections. This is not required.

show databases
use sengi
show collections
db.createCollection('trees')
db.trees.drop() # to remove it again.

Development

Code base adheres to the rules chosen by https://standardjs.com/. Code is formatted with 2 spaces.

Tests are written using Jest with 100% coverage.

npm test

Note that the tests run sequentially (jest --runInBand) so that only one test can access the database at a time.

Continuous Deployment

Any pushes or pull-requests on non-master branches will trigger the test runner.

Any pushes to master will cause the library to be re-published.
