Consume RESTful API Endpoints Within A Golang Application

July 24, 2017

I am a huge fan of the Go programming language and have written a decent amount of material on the subject. For example, a popular tutorial I wrote titled, Create a Simple RESTful API with Golang, focuses on developing an API. However, I recently received questions on the subject of consuming data from other APIs from within a Go application.

We’re going to see how to issue HTTP requests from within Go, in an effort to consume or send data to other RESTful APIs that might exist on the internet.

More than a year ago, before I started using Angular, I had written a tutorial on the topic of fingerprint authentication in a core NativeScript application. Since then, I’m doing almost all of my mobile development with Angular which means that the previous article deserves an upgrade.

I recently released a mobile application called Solar Flare for Cloudflare that protects your account with device level fingerprint authentication. We’re going to see how I included fingerprint authentication, sometimes referred to as touch id, in a NativeScript with Angular application.

If you’ve been keeping up with my content since the birth of The Polyglot Developer, you’ll know that I was once a huge advocate of Apache Cordova development using frameworks like Ionic Framework. Having been a web developer and coming from native Android development with Java, cross-platform development using hybrid technologies seemed like a logical next step. Fast-forward to now, I’m no longer using Apache Cordova with Ionic Framework and have gone back to native development.

I recently came across an article by Ionic’s CEO, Max Lynch, titled, Cordova/Ionic Apps are Native Apps, trying to explain that Ionic applications are native mobile applications. There are some valid points made in this article, but as someone who spent several years using the technology as well as using applications built with the technology, it is not something I agree with as a whole.

A while back I wrote a tutorial that demonstrated how to use local notifications in a NativeScript Core project, also referred to as a vanilla NativeScript project. Since writing that tutorial I had received several requests to demonstrate the same in a NativeScript with Angular project.

If you’re unfamiliar, local notifications are scheduled notifications rather than notifications sent from a server. These notifications are useful when you need to trigger reminders in your application or based on events. For example, maybe you develop an iBeacon application and as you approach an iBeacon you want to receive a notification. This type of notification would be a local notification.

We’re going to see how to schedule and display notifications in Android and iOS using NativeScript and Angular.

Most, not all, mobile applications have some sense of users having accounts. This means that users need to register and sign into most mobile applications to get all the features the application has to offer. So how do you create an attractive and functional login and registration screen for your Android and iOS application?

We’re going to see how to create a registration and login screen with NativeScript and Angular that will get you to an end result of a protected page within your application.

Anyone that operates a website or web application with a contact page knows how bad the SPAM problem on the internet is. Spammers, phishers, and other malicious people create bots that will crawl search engines for contact forms and send emails to the hosts, register accounts, or something else. There was a point in time that I was receiving more than ten emails a day from spammers that wanted to redesign my website. This kind of activity is incredibly annoying on my inbox.

This is where CAPTCHA and reCAPTCHA form elements come into play. These elements typically require some interaction such as typing words from an image or solving a math problem. Adding this small amount of form complexity can go a long way towards stopping bots.

We’re going to see how to hook up a Google reCAPTCHA element into a client facing form and validate that element using a Node.js backend.
