Redux Thunk is one of the most if not the most popular Redux middleware with over 2 million downloads a month. If you compare this number to the Redux 4 million downloads a month, it is easy to figure out that over half of Redux projects are using Redux Thunk. As the name “thunk” suggests, the main goal of Redux Tunk is to allow for lazy evaluation (dispatching) of actions. While this makes it possible to dispatch actions in an asynchronous manner, it also makes it harder to test.
Fixtures are a thin abstraction layer over sample data in your application which allows for better organizing, often complex, data structures representing different entities. If this sounds like a vague description or does not ring the bell maybe an example will speak to you better.
There are a few major reasons due to which you may find yourself creating a library. One, obviously, is that you have a solution which you would like to share with the Open Source community. The other one is that you need to reuse code across different projects or in the same project but on different platforms.
React works, in what I would call, homogeneous manner. A tree of components is going to be rendered in the given component using a render or recently introduced hydrate function. You are not supposed to change DOM elements created by React or at least do not change components which can return true from shouldComponentUpdate. But what if you need to change an element outside of the React realm? Well, portals are the way to go!
This guide is a form of writing down few techniques that I have been using with ups and downs for the past two years. Optimizations highly depend on your goals, how users are experiencing your app, whether you care more about time to interactive or overall size. It should not come as a surprise, that like always, there is no silver bullet. Consider yourself warned. Although you have to optimize for your use cases, there is a set of common methods and rules to follow. Those rules are a great starting point to make your build lighter and faster.
When you ask someone to send you a contract or a report there is a high probability that you’ll get a DOCX file. Whether you like it not, it makes sense considering that 1.2 billion people use Microsoft Office although a definition of “use” is quite vague in this case. DOCX is a binary file which is, unlike XLSX, not famous for being easy to integrate into your application. PDF is much easier when you care more about how a document is displayed than its abilities for further modifications. Let’s focus on that.
Geofencing allows for locating points within defined geographic areas. Areas can be defined with geographic points, consisting of latitude and longitude, forming any shape. HERE provides Geofencing Extension API for that purpose.
I know, I know. This title sounds cocky. In fact, it makes a lot of sense if you think about it. I have been asked multiple times by my friends from our local React meetup group I am organizing or by teams I am helping to develop their applications for a starter, boilerplate or a setup. This post is a result of another such question. Most of the time it is one of the two scenarios.
