Serverless MongoDB local plugin

• Automatically starts/stops a local MongoDB instance
• Automatically downloads MongoDB binaries on first use
• Can be used as a local equivalent to DocumentDB/CosmosDB

npm i -D serverless-mongodb-local

plugins:
  - serverless-mongodb-local
custom:
  mongodb:
    stages: # If you only want to use MongoDB Local in particular stages, declare them here as a string or regex
      - dev
      - 'dev-\d+'
    instance: # MongoMemoryServer() options and defaults https://github.com/nodkz/mongodb-memory-server#available-options-for-mongomemoryserver
      port: 1234
      dbName: MyDB
      dbPath: ./db
      storageEngine: wiredTiger # Set with `dbPath` to persists the database between instantiations
    seed:
      auto: true
      dataPath: ./test/data

const { MongoClient } = require('mongodb');
const client = await MongoClient.connect(
  process.env.SLS_MONGODB_URI,  // Provided as a convenience when using the plugin (local only, requires --localEnvironment flag to be set on the command line) 
  { useUnifiedTopology: true }
);

By setting a mongodb.seed.dataPath any .json files in the folder will be imported as collections. The name of file being the name of the collection. The file should be an array of documents to load into the collection.

plugins:
  - serverless-mongodb-local
  - serverless-offline

Make sure that serverless-mongodb-local is above serverless-offline so it will be loaded earlier.

Now your local MongoDB database will be automatically started before running serverless-offline, when using the command sls offline start.

# Start the db
sls mongodb start --localEnvironment 
# Seed the db
sls mongodb seed --localEnvironment

• Inspired by serverless-dynamodb-local
• MongoDB install/control provided by mongodb-memory-server
