When you start working with streams, you can’t help to notice that you listen to stream events and this is because it us

Streams allow for time and memory-efficient data transferring which is definitely something you want to take advantage of taking into consideration the single-threaded server-side nature of NodeJS.,Then, I found WordPress. And like every other whippersnapper in front of a computer screen with some basic PHP knowledge, WordPress changed everything. This was cool, right?,Although the constructor function allows you to do some very nice stuff, if you find yourself reaching out for its prototype is a sign you need to use “class” which are supported pretty much anywhere. It is cleaner and something people are more likely to understand.,Yes, NodeJs is not Javascript and Javascript is the number 1 thing to learn before you get into NodeJs and I shared a list of 10 things you need to focus on when learning Javascript in a different article.,Javascript is powerful and flexible which allows you to code any way you like and try some very unusual things which can lead to a bug in your code. Here are 50 things I learned about coding in Javascript you should know about.,Be consistent with the way you declare things. Put all your declarations on top starting with the constants down to the variables. Make constants all uppercase to indicate they are constants which will prevent devs from trying to change them.,ArrayBuffer is part of Javascript and in NodeJs, streams are everywhere. Pretty much NodeJs is “built on streams”. Funny enough, streams are one of the most misunderstood things and often regarded as hard to grasp by people coming into NodeJs.,NodeJs is a runtime environment for Javascript, an environment to run Javascript and not a programming language. NodeJs is to Javascript on the Server as Browser is to Javascript on the Client.,Avoiding creating things in global objects unless you are creating a library/framework. Global property names may collide with third parties or something a colleague also introduced and are hard to debug.,In non-production environments, we safely over commit resources as much as possible by keeping resource requests extremely low and limits extremely high. The limiting factor in this case is memory i.e. no matter how low the memory request is and how high the memory limit is, pod eviction is a function of sum of memory utilized by all containers scheduled on a node.,Prefer immutability as much as possible. Constantly changing data and passing it around can make it hard to track bugs and the changes itself. Work on data copies and avoid side effects.,Destructuring is elegant and makes it more obvious what you need from array and objects and also gives you the opportunity to rename things to help give more sense to your code.,Like the above examples, destructuring is a good way to extract the data you need to do the job but, also make it a habit to only call methods and functions with the things they need. This also goes to the data coming from the API. Extract and cleanup only the data you need before storing or doing anything to it.,It is also important to know when something is part of the environment or the language. For example, it is common to find devs that think that “setTimeout” is part of Javascript, but it is just part of the environment (Window or NodeJs Global).,As something so important in Node, it should be a high priority thing to learn about and you cannot talk about streams without mentioning buffer, ArrayBuffer, pipe, back pressure, etc. It is also important to master all the stream types, writable, readable, transform, and duplex.
