When you’re developing an Android mobile application, it is critical that you come up with a nice launcher icon for all possible Android screen densities. If you’re not too familiar with Android, there are mdpi, hdpi, xhdpi, xxhdpi, and xxxhdpi densities as of now. This number could change in the future.
Once you’ve got your icon, resampling or resizing it for each possible screen density can become a pain in the butt. Instead, it makes sense to use or create a script for this.
If you’ve been keeping up, you’ll remember I wrote about image generators in an article titled, Generating Splash Screens and Application Icons for NativeScript Mobile Apps. Since we’re talented developers, we’re going to create our own service this time around.
We’re going to see how to create a RESTful API that accepts an image and generates various sizes of that same image, bundled within a ZIP archive. We’re going to accomplish this task with Node.js and Express.Read More
Previously I had written about configuring cross-origin resource sharing via a Golang RESTful API, but this time we’re going to explore the same using Node.js and Express Framework.Read More
When I build web applications, my least favorite part is always in the realm of file uploads. They are often complicated to do and take a lot of time. Pretty much every web application lately, regardless of what it is, requires file uploads, even if it is just to upload a profile picture.
Since I’m all about Angular 2 lately, I figured it would be great to show how to upload images (or any file) to a back-end. In this particular example I’m using Node.js.Read More
I was at an event not too long ago where someone recommended I take a look at PassportJS for my Node.js applications. In case you’re unfamiliar with PassportJS, it is an authentication middleware that makes it easy to work with logins, whether they are with basic login, or with social media accounts such as Facebook and Twitter.Read More
Previously I wrote about how to create an AngularJS application with PouchDB and Couchbase. The way I demonstrated is of course one way to accomplish the job of using Couchbase in a web application. This time around we’re going to take a look at creating a full stack application using the Couchbase, ExpressJS, AngularJS, and Node.js (CEAN) stack.
You might be familiar with the MongoDB, ExpressJS, AngularJS, and Node.js (MEAN) stack, but I’m going to show you that this is just as possible with Couchbase and even easier to do.
We’re going to see how to install and configure all four of the CEAN stack services as well as make a very simple application out of them.Read More
I’ve written a few tutorials regarding Node.js and the ExpressJS framework, but I never took a step back and explained how to make a super simple RESTful API for processing HTTP requests from a front-facing interface.
Have you ever wanted to fetch remote HTML data in a similar fashion to cURL or Wget using some backend web service and parse it? If you said no, don’t worry, I said the exact thing until I was challenged to do so. For the challenge, I chose to use Express as my framework and a few libraries to assist in the process of fetching and parsing.Read More
