Real-Time Location Changes with MongoDB Realm, Change Streams, and Mapbox

June 25, 2020 Nic Raboy

When it comes to modern web applications, interactions often need to be done in real-time. This means that instead of periodically checking in for changes, watching or listening for changes often makes more sense.

Take the example of tracking something on a map. When it comes to package shipments, device tracking, or anything else where you need to know the real-time location, watching for those changes in location is great. Imagine needing to know where your fleet is so that you can dispatch them to a nearby incident?

When it comes to MongoDB, watching for changes can be done through change streams. These change streams can be used in any of the drivers, including front-end applications with MongoDB Realm.

In this tutorial, we're going to leverage MongoDB Realm change streams. When the location data in our NoSQL documents change, we're going to update the information on an interactive map powered by Mapbox.

Web Services for the Go Developer, First Edition

August 19, 2019 Nic Raboy

I'm pleased to announce that my eBook titled, Web Services for the Go Developer, has been published! This is my second book and was inspired by my previous book with nearly the same name that focused on JavaScript development rather than Go development.

So what is the objective of this book?

It is important for developers to be familiar with web services that follow the GraphQL or REST specification, not only from the perspective of using those web services, but also in designing and developing them. The objective of this book is to teach Go developers, through example, how to do just that.

Developing A GraphQL API With Node.js And MongoDB

February 25, 2019 Nic Raboy

While REST APIs are amongst the most popular when it comes to client consumption, they are not the only way to consume data and they aren't always the best way. For example, having to deal with many endpoints or endpoints that return massive amounts of data that you don't need are common. This is where GraphQL comes in.

With GraphQL you can query your API in the same sense that you would query a database. You write a query, define the data you want returned, and you get what you requested. Nothing more, nothing less. I actually had the opportunity to interview the co-creator of GraphQL on my podcast in an episode titled, GraphQL for API Development, and in that episode we discuss GraphQL at a high level.

You might remember that I wrote a tutorial titled, Getting Started with GraphQL Development Using Node.js which focused on mock data and no database. This time around we're going to take a look at including MongoDB as our NoSQL data layer.

Developing A RESTful API With Golang And A MongoDB NoSQL Database

June 27, 2019 (Updated) Nic Raboy

If you've been following along, you're probably familiar with my love of Node.js and the Go programming language. Over the past few weeks I've been writing a lot about API development with MongoDB and Node.js, but did you know that MongoDB also has an official SDK for Golang? As of now the SDK is in beta, but at least it exists and is progressing.

The good news is that it isn't difficult to develop with the Go SDK for MongoDB and you can accomplish quite a bit with it.

In this tutorial we're going to take a look at building a simple REST API that leverages the Go SDK for creating data and querying in a MongoDB NoSQL database.

Using Hapi.js, Mongoose, And MongoDB To Build A REST API

February 18, 2019 Nic Raboy

To continue on my trend of MongoDB with Node.js material, I thought it would be a good idea to use one of my favorite Node.js frameworks. Previously I had written about using Express.js with Mongoose, but this time I wanted to evaluate the same tasks using Hapi.js.

In this tutorial we're going to develop a simple RESTful API using Hapi.js, Joi and Mongoose as the backend framework, and MongoDB as the NoSQL database. Rather than just using Hapi.js as a drop in framework replacement, I wanted to improve upon what we had previously seen, by simplifying functions and validating client provided data.

Hash Password Data In MongoDB With Mongoose And Bcrypt

February 11, 2019 Nic Raboy

When creating a web application that handles user information it is a good idea to protect anything considered sensitive rather than storing it as plaintext within a database. The goal is to make it as difficult as possible for a malicious person to obtain access to this sensitive information. Rather than encrypting sensitive information with the knowledge that it can one day become decrypted, it is better to hash this sensitive data instead because hashing is a one-way process.

In this tutorial we're going to take a look at hashing password data with bcryptjs before storing it in a MongoDB NoSQL database with Mongoose and Node.js.

Building A REST API With MongoDB, Mongoose, And Node.js

February 4, 2019 Nic Raboy

About a week or so ago I had written a tutorial titled, Getting Started with MongoDB as a Docker Container Deployment, which focused on the deployment of MongoDB. In that tutorial we saw how to interact with the MongoDB instance using the shell client, but what if we wanted to actually develop a web application with MongoDB as our NoSQL database?

In this tutorial we're going to see how to develop a REST API with create, retrieve, update, and delete (CRUD) endpoints using Node.js and the very popular Mongoose object document modeler (ODM) to interact with MongoDB.
