When developing an application with the Go programming language, you might find yourself needing to save data locally. If you’ve been keeping up you’ll remember that I’ve written about storing data remotely with Golang in a Couchbase NoSQL database, but never anything locally. Probably the easiest w...

Not too long ago I wrote about containerizing a bunch of web applications and putting them behind an NGINX reverse proxy. This is because I’ve been exploring the possibility of taking all my personal applications and turning them into Docker containers for easy maintenance and portability. I current...

I personally think that Golang is a great development technology and one of the better that I’ve used. However, there is no such thing as a perfect development technology. That said, there are things to be desired in Golang out of the box. For example, I always find myself wishing that I could use t...

You can do a lot of cool things with Docker, for example containerizing web applications, processes, and a bunch of other things. What happens when you want to deploy your database as a container, or more specifically, your distributed database as containers? Most NoSQL databases are distributed, me...

When it comes to learning Angular, the go-to example is the Tour of Heroes tutorial that is found in the official Angular documentation. This is a great tutorial because it covers a lot of topics, however, it is a web application tutorial. What if we wanted to build a mobile application from it, or ...

So I was recently playing with Docker using a mixture of docker-compose and the docker commands and I found myself with a container communication issue. I was trying to spin up a container to communicate with containers launched via docker-compose, but my new container couldn’t find these other cont...

Continuous deployment (CD) is a very interesting subject. Being able to establish a build pipeline that deploys your application once building is complete is a fantastic form of automation. Jenkins is one of the most popular, if not the most popular, continuous integration (CI) and continuous deploy...

When building a mobile application, there are often scenarios where you need to storage files remotely and when I say files, I don’t mean database data. For example, maybe you want to develop an image manager or photo storage solution like what Facebook and Instagram offer? There are many solutions,...

When I’m developing with Angular, I often find myself needing to loop over an object via HTML markup. In AngularJS one could loop over object properties or arrays, but in Angular you can only loop over arrays by default. This is easily fixable through what are known as Angular Pipes. With pipes you ...

Have you ever built an application and decided that you didn’t want to hardcode a bunch of values that might change frequently? The answer is, probably yes. When building a web application, it is common to separate configuration details into a separate file which might contain database information, ...

I’ve been on and off when it comes to Docker, but lately I’ve been starting to embrace it. In comparison to virtual machines, containers a lot easier to maintain and are more lightweight. While working with containers are great, their true power aren’t made visible until you start clustering them. T...

Over the past few weeks I’ve been doing a lot of investigation into JSON Web Tokens (JWT) for authentication in APIs. If you’ve been keeping up, you’ll remember I wrote about JWT authentication in a Node.js application as well as building a client facing NativeScript and Angular mobile application t...

I am pleased to announce that the latest episode of The Polyglot Developer Podcast has been published to all the popular podcasting networks which include, but are not limited to, iTunes and Pocket Casts. In this episode titled, The Go Programming Language and Where it Fits in Modern Development, I ...

Ever found yourself working with comma separated value (CSV) data from a file or other source? This format is easy to generate if you’re working with spreadsheet applications like Google Sheets or Microsoft Excel, and RDBMS applications. So how do we load this data and work with it in an application...

When building a web application, not only do you need amazing features, but you also need a stunning user experience and that can often be managed by making good use of UI components. When I’m using my favorite web applications, the way components are displayed on the screen are sometimes what makes...

Any mobile application that accesses remote data will need authentication at some point in time. There are many different authentication strategies out there, one of which is with Json Web Tokens (JWT) that we explored in one of my previous Node.js articles. With JWT, users can authenticate via user...

I’ve been working with Docker for a while now and I’ve found that I’m rarely using one of the vanilla images found on Docker Hub. By rarely, I don’t mean never, but in most cases I find that I’m building my own custom Docker image for any web application that I wish to containerize. This allows me t...

So I’ve been working on a project that uses the Go programming language. The application I’m building is a web application that I plan to distribute. The thing is, I don’t want to distribute hundreds of files to make it possible. The application has an API built with Go and the front-end that consum...

You might have noticed that I’m doing quite a bit of Docker related articles lately. This is because I’ve been exploring it as an option for the future of my personal web applications. As of right now I’m serving several web applications on Digital Ocean under a single Apache instance. As requests c...

While I don’t see a lot of it anymore, XML is still a common data format that people use. I prefer JSON, but I don’t always have a say in how I receive data. Some time ago I wrote a few tutorials on which include parsing XML data with Node.js, parsing XML data with Java, and parsing XML data with PH...

When it comes to API development, there is often a need to protect certain endpoints or rate-limit the API in general. Because you are working with endpoints from clients possibly on a different domain, you can’t authenticate users with sessions and cookies. It would also be a bad idea to pass aroun...

If you haven’t already gotten involved with it, you’ll probably know that TypeScript is becoming increasingly popular. Being able to use a superset of JavaScript in a typed language that compiles down to JavaScript is a great thing. However, if you’ve ever played around with TypeScript and tried to ...

The recent Amazon S3 outage that took down much of the internet inspired me to talk about alternatives. Not too long ago I wrote about an open source object storage software called Minio and how I was using it on my Raspberry Pi for backups. The great thing about Minio is it shares the same APIs as ...

When I use Docker, most of the time I start my containers in detached mode, meaning that the container will deploy in the background without any further interaction from myself. However, every once in a while I find myself needing to connect to the container to view log information. So how do you co...

I get a particular set of questions quite a bit on my blog and other social media outlets. One of these questions includes how to use geolocation features such as GPS tracking within a NativeScript mobile application for iOS and Android. Many people want to be able to gather location information and...

I release a lot of content and build a lot of mobile applications using the NativeScript mobile framework, most of which includes Angular. Lately I’ve been getting many requests for information on using a side drawer within the application. These side drawer components can improve the user experienc...

When building mobile applications you’ll often find yourself needing to create child components. What do I mean by child components? Take for example a mobile application with two different screen groupings, one where the user is not signed in and the other where the user is signed in. In each of th...

As you probably know, I’m a fan of the Raspberry Pi and Pi Zero Internet of Things (IoT) devices. Well, I recently had a moment where I felt like a total newbie. I go through a lot of installations of Raspbian Linux and during every installation I go through a network configuration process. This pro...

Social media can be huge towards building your brand and promoting your mobile application. It can also make a difference in the user experience of your application. Allowing users to share text and media on their own social media profiles could be huge, no matter how you look at it. A while back I ...
