### [22. How to Run Node.js in a Browser [Tutorial]](https://hackernoon.com/how-to-run-nodejs-in-a-browser-wc4s32by)
![](https://cdn.hackernoon.com/drafts/n16832io.png)
"Browser based bundler" is a very interesting topic.

For example, can we compile the webpack code in the browser instead of the server's nodejs environment? The advantage of this is that we don't need the server's resources for compilation.

There are different solutions to this problem. For example, codesandbox, which defines a browser-based compilation strategy, can be used to package reacts, vue, etc. in the browser. It can also be easily understood that codeandbox does a browser version of webpack.

But the question is, can we execute webpack in the browser instead of doing a new one? Even implementing some webpack-based libraries?

There is a very early webpack issue discussing it . But this demo is too old to run the latest version of webpack.

I am wondering if we can do a browser environment to simulate running Node.js. Node.js and Chrome is both v8, and many of the Node.js lib code can be executed in Chrome. In addition, I found some cool libraries, such as BrowserFS, memfs, rollup-plugin-node-builtins, etc. These libraries can help us build this environment. But there is a key module, Node.js "module" is not available, we need to modify it from Node.js. Node.js supports cjs and esm, but to simplify the problem, I only develop the cjs module for the time being. Next, combine all the modules and try to run the simplest Node.js demo.

To learn coding is not just being familiar or comfortable with the syntax but to understand the logic and improve logical and analytical skills. Every programming language has advantages and disadvantages but the basics are the same to a certain extent. We all know that the best method to learn a programming language is writing codes in it. It is also known that the key developers not just write the code but enjoy doing it. If the basics are not sorted, advanced programming tends to be boring.

Genetic Algorithms , also referred to as simply “GA”, are algorithms inspired in Charles Darwin’s Natural Selection theory that aims to find optimal solutions for problems we don’t know much about. For example: How to find a given function maximum or minimum, when you cannot derivate it? It is based on three concepts: selection, reproduction, and mutation. We generate a random set of individuals, select the best ones, cross them over and finally, slightly mutate the result - over and over again until we find an acceptable solution. You can check some comparisons on other search methods on Goldberg's book.

It took at least half a day to clone and build the whole source code. Over the next year or two in which my team worked with a monorepo, we just suffered — cloning the repo was time-consuming; the slow build/release time frustrated us; flaky tests and bad commits affected all the engineering; and let’s not even mention the IntelliJ indexing time, which easily afforded us time to run down for a chatty coffee break.

Golang is a concurrent programming language. It has powerful features like Goroutines and Channels that can handle asynchronous tasks very well. Also, goroutines are not OS threads, and that's why you can spin up as many goroutines as you want without much overhead, it's stack size starts at 2KB only. So why async/await? Async/Await is a nice language feature that provides a simpler interface to asynchronous programming.

Bulma is a free, open-source CSS framework based on Flexbox and used by more than 200,000 developers. It's the easiest to learn (my opinion) due to its natural naming of classes and a simple grid system. It's not that popular like Bootstrap, but it got a specific fanbase.

Since the early days of Unix, the shell has been part of the user's interface with the operating system. The first Unix shell (the Thompson shell) had very limited features, mainly I/O redirection and command pipelines. Later shells expanded on that early shell and added more and more capabilities, which gave us powerful features that include word expansion, history substitution, loops and conditional expressions, among many others.

I know, it’s been a while since the last time I published something newbies-friendly on my blog. The main reason is that most of my readers are either experienced devs or from C background having modest C++ encounter. But while programming in C++ you need a completely different mindset as both C & C++ belongs to different programming paradigm. And I always strive to show them a better way of doing things in C++. Anyway, I found the topic which is lengthy, reasonably complex(at least it was for me), newbies-friendly as well as energizing for experienced folks(if Modern C++ jargons, rules & features added) i.e. C++ Template.

In software engineering, Creational Design Patterns deal with object creation mechanisms, trying to create objects in a manner suitable to the situation. The basic or ordinary form of object creation could result in design problems or added complexity to the design. Builder Design Pattern in C++ solves this specific problem by separating the construction of a complex object from its representation.

Whether you're making API calls from Node.js or in the browser, connection failures are going to happen eventually. Some request errors are valid. Maybe the endpoint was wrong or the client sent the wrong data. Other times you can be sure that the error is the result of a problem with the connection to the server or one of the many hops in-between. While API and web service monitoring can inform you about the problem, a more active solution can take care of it for you.
