When you are still early on in your programming career, digging into the source code of open source libraries and frameworks can be a daunting endeavor. Reading source code is difficult at first but it becomes easier with time. The goal is not to understand everything but to come away with a different perspective and new knowledge.In this article, Carl Mungazi shares how he got over his fear and began using source code to improve his knowledge and skills. He also uses Redux to demonstrate how he approaches breaking down a library.

In this second part of our tutorial on building Sketch plugins, Matt Curtis will pick up where he left off with the building of our user interface, and then he’ll move on to the key feature of actually generating our layer mosaics and optimizing the final plugin code. You will learn how to connect the user interface to the core plugin code and how to implement the plugin’s main features. Last but not least, you’ll also learn how to optimize the code and the way the plugin works.

The user experience from a developer point of view is seriously lacking. We don’t get any helpful warnings when we misspell words, misuse APIs or, well, anything, really! We’ve already seen how we can implement the basic parts of our validation library, and how to add all the nice-to-have features we needed. In this final part of this series, Kristofer Giltvedt Selbekk will focus on improving the user experience for the people that will use our validation library: the developers.

In Kristofer’s previous article, he explained how the basic parts of a validation library can be implemented. While the next part will focus on improving the developer experience, today’s article will focus on adding more features to what was created in Part 1. Kristofer will continue implementing the validation library you started implementing in the previous part of this series. These are the features that are going to take us from a simple proof of concept to an actual usable library!

Do websites created with reactive frameworks get indexed by Google and other search engines? Is it compulsory to set up pre-rendering, as your SEO consultants suggest? Or are they wrong? In this article, Paolo Mioni will talk mostly about Vue.js, since it is the framework he’s used most, and with which he has direct experiences in terms of indexing by the search engines on major projects, but most of what will be covered is valid for other frameworks, too.

Ever wondered how validation libraries work? In this article, Kristofer Giltvedt Selbekk will tell you how to build your very own validation library for React step by step. You will go through the process step by step, and you’ll find CodeSandbox examples as we go along. By the end of this post, you will know how to write your own validation library, or at the very least have a deeper understanding of how other libraries implement “the magic of validation”. The next part will add some more advanced features, and the final part will focus on improving the developer experience.

When designing interfaces for IoT web page, one always has many options. In the previous part of this article, Richard Leddy shed light on the meaning of IoT and how Vue.js can be used to hosts groups of IoT human-machine interfaces. Today, Richard Leddy will take a closer look at lazy-loading panels and how to keep the Vue state in sync with devices. More about the editing process may be considered in some other discussion. There is a lot to it. But, for now, we have the tools we need in order to load hierarchal components and make them come alive.
