To export the environment variable, run:Ĭlass Repository ( object ): def _init_ ( self, adapter = None ): self. You might have noticed that the MongoRepository class reads a environment variable MONGO_URL. Notice that all methods explicitly use the pymongo API. deleted_countĪs you can see the MongoRepository class is straightforward, it creates a database connection on its initialization then saves it to a instance variable to be use later by the methods: find_all(), find(), create(), update(), and delete(). modified_count def delete ( self, selector ): return self. insert_one ( kudo ) def update ( self, selector, kudo ): return self. find_one ( selector ) def create ( self, kudo ): return self. find ( selector ) def find ( self, selector ): return self. kudos def find_all ( self, selector ): return self. Import os from pymongo import MongoClient COLLECTION_NAME = 'kudos' class MongoRepository ( object ): def _init_ ( self ): mongo_url = os. Check the version of Python installed by running the following command: MongoDB or the Docker toolbox installed.To complete this tutorial, there are few things you will need: Learn More About Python, Flask, and React.Add Authentication to Your React App with Okta.Python ReST API Persistence with MongoDB.Our app will be a GitHub open source bookmark project (a.k.a kudo). In this tutorial you are going to build a JavaScript application using React in the front-end and we are also going to build a ReST API written in Python which is going to persist. It facilitates the creation of complex, interactive, and stateful UIs from small and isolated pieces of code called components. React is a declarative, efficient, and flexible JavaScript library developed at Facebook for building user interfaces. You’ll also use Flask to help you to quickly put together a ReST API. The language states on its core values that software should simple, readable making developers more productive and happier. Python is a dynamic language widely adopted by companies and developers.

Today’s modern web applications are often built with a server-side language serving data via an API and a front-end javascript framework that presents the data in an easy-to-use manner to the end user.
