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.

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.

Query A GraphQL API With Vue.js And Axios

January 16, 2019 Nic Raboy

I've written quite a bit of content around developing a GraphQL API with various programming technologies such as Node.js, Golang, and Java. Heck, I even wrote an eBook on the subject titled, Web Services for the JavaScript Developer. However, I haven't really produced any content around interacting with those APIs using modern frameworks and client facing technologies, only cURL and Postman.

So how do you interact with a GraphQL API using something like Angular, React, or Vue.js?

There are a lot of frameworks to cover, but in this particular tutorial we're going to see how to use Vue.js and simple JavaScript to interact with a GraphQL API.

Perform Different Text Animations With jQuery

January 14, 2019 Nic Raboy

When it comes to my name, there is often a lot of confusion. On social media sites such as Twitter, GitHub, and similar, I often go by nraboy which is the first character of my first name (Nic) followed by my last name (Raboy). When people see that, they often think of The National Rifle Association (NRA), which is obviously unrelated to what I'm trying to present myself as. However, due to the NRA acronym being similar to my online handles, I get included on a lot of crazy conversations that I really don't want to be a part of. In fact, it is one of the main reasons why the blog was rebranded from blog.nraboy.com to thepolyglotdeveloper.com.

Out of this I decided to create an animation showing the obvious. Rather than putting my video editing skills to the test, I decided to create an animation using jQuery and simple JavaScript. In this tutorial we're going to play around with some text animations using jQuery.

Implementing U2F Authentication With Hardware Keys Using Node.js and Vue.js

January 7, 2019 Nic Raboy

Not too long ago I had written a tutorial titled, U2F Authentication with a YubiKey Using Node.js and jQuery, which demonstrated how to use hardware keys as a means of universal two-factor (U2F) authentication. However, I had left some things to be desired in that previous post. For example, the previous tutorial did not use proper session management with Express.js and it used jQuery, which is neat, but by no means is as popular as some of the other web frameworks that currently exist.

In this tutorial, we're going to expand upon what we had done previously, but implement proper session management with Express.js and use Vue.js, which is a modern web framework.
