Integrate with MongoDB

MongoDB is a flexible document database system that stores data in JSON-like documents.

Node.js

Documentation: http://mongodb.github.io/node-mongodb-native/
NPM: https://www.npmjs.com/package/mongodb
Source Code: https://github.com/mongodb/node-mongodb-native

Getting started

1. Create a MongoDB client in /less/shared/mongodb_client/index.js.

   /less/shared/mongodb_client/index.js

   const { MongoClient } = require('mongodb');
   
   const MONGODB = {
     URI: 'mongodb+srv://YOUR_MONGODB_URI',
     DATABASE_NAME: 'YOUR_DATABASE_NAME',
     COLLECTION_NAME: 'YOUR_DATABASE_COLLECTION'
   };
   
   let client;
   const connect = async () => {
     if (!client) {
       client = new MongoClient(MONGODB.URI);
       await client.connect();
     }
   };
   
   const insert_item = async (item) => {
     await connect();
     const db = client.db(MONGODB.DATABASE_NAME);
     const collection = db.collection(MONGODB.COLLECTION_NAME);
     return await collection.insertOne(item);
   };
   
   const list_items = async () => {
     await connect();
     const db = client.db(MONGODB.DATABASE_NAME);
     const collection = db.collection(MONGODB.COLLECTION_NAME);
     return await collection.find().toArray();
   }
   
   module.exports = {
     insert_item,
     list_items
   };

2. Create a POST /items route in /less/apis/demo/items/post.js.

   /less/apis/demo/items/post.js

   const { insert_item } = require('mongodb_client');
   
   exports.process = async (request, response) => {
     const payload = JSON.parse(request.body);
     await insert_item(payload);
     response.body = JSON.stringify(payload);
     response.statusCode = 201;
     return response;
   };

3. Create a GET /items route in /less/apis/demo/items/get.js.

   /less/apis/demo/items/get.js

   const { list_items } = require('mongodb_client');
   
   exports.process = async (request, response) => {
     const result = await list_items();
     response.body = JSON.stringify(result);
     response.statusCode = 200;
     return response;
   };

Python

Documentation: https://pymongo.readthedocs.io/en/stable/
Pypi Package: https://pypi.org/project/pymongo/
Source Code: https://github.com/mongodb/mongo-python-driver

Getting started

1. Create a Python Mongodb client in /less/shared/mongodb_client_py/__init__.py.

   import os
   from pymongo import MongoClient
   
   MONGODB_URI = os.environ.get('MONGODB_URI')
   MONGODB_DATABASE_NAME = os.environ.get('MONGODB_DATABASE_NAME')
   
   client = MongoClient(MONGODB_URI)
   db = client[MONGODB_DATABASE_NAME]
   collection = db.['my_collection']
   
   def insert_item(item):
       post_id = collection.insert_one(item)
   
   def get_all_items():
       return collection.find()

2. Create a GET /hello/py route in /less/apis/demo/hello/py/get.py to test.

   from mongodb_client_py import insert_item, get_all_items
   
   def process(request, response):
       # Insert item.
       insert_item({ 'bar': 'baz' })
   
       # Get all items.
       result = get_all_items()
       
       # Return HTTP response.
       response.body = result
       return response
