![]() Open a second terminal window, navigate to the Unit-12 directory, and load the data into MongoDB: npm run load-db (this takes several minutes to run). NOTE: All the examples below use async/await syntax. Add code to connect to the server and the database myProject. Create a new app.js file and add the following code to try out some basic CRUD operations using the MongoDB driver. If you're running MongoDB locally, start the MongoDB daemon: npm run start-mongod in its own dedicated terminal window. You should see the mongod process start up and print some status information. We start our Node.js project by going into a new folder (call it tripcost) and typing the command npm init -y. Run npm install to install the necessary packages from the npm registry. I am going to use a local installation of Node.js. We have our first endpoint, which will accept a name property. When clicked, the app will send the name to us, to the /trip endpoint with the POST HTTP method. I imagine the app will ask the user for the name, and there will be a “Create trip” button. Let’s now dissect this into details, and translate it into a series of API endpoints.Īn endpoint is a unique URL we will call to create an operation.Īt the beginning, there is no trip stored, and we need to add one. We’re not going to create the frontend of the application here, just the API. When the trip ends, you archive it and it becomes part of the history - which you can navigate and see how much you spent in the past trips. Gasoline, hotels, food, tickets and so on. Imagine going on a trip, and you have your app (which can be a progressive web app, or a mobile app for example) where you add any expense you make. The mongodb module provides the driver to connect. But this module would have to be downloaded using NPM (Node Package Manager). As with reading user input, for MongoDB as well we have a Node.js module called mongodb. Our task is to create a trip cost calculator app. Read: How to Install MongoDB on Windows Lets now see how to connect to MongoDB from Node.js. Tip: make sure you installed a MongoDB database on your system before going on with the tutorial (or use a cloud MongoDB database if you prefer) ![]() We’ll use a MongoDB database to store this data. This API will expose a set of GET and POST endpoints to allow getting data out, and sending data in. Thus, a combination of Node.js and MongoDB forms a powerful technology stack. It offers its users a fast development cycle and efficient performance. Although there are many NoSQL databases, MongoDB is a perfect fit for use with Node.js. Starting with our first nodeJS code to connect to the database. Using Node Js with MongoDB CRUD is a combination that is very powerful. > 'C:\Program Files\MongoDB\Server\3.6\bin\mongod.exe'. In the case of Windows, use the below command. In this tutorial we’ll create a REST API using Node.js and Express. To get started, start the MongoDB service using the below command.
