![](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.

Low-level languages like C, have manual memory management primitives such as malloc() and free(). In contrast, JavaScript automatically allocates memory when objects are created and frees it when they are not used anymore (garbage collection). This automaticity is a potential source of confusion: it can give developers the false impression that they don't need to worry about memory management.

One of the main reasons for using Node.js is that you can create quickly RESTful web APIs with it. Express is a popular web framework helping you with this task. Using JavaScript to build servers is often a natural choice for frontend developers looking for a way to reuse their skills and create the APIs supporting their web app, but that's not the only benefit of using Node.js. The huge package ecosystem around Node.js and Express is what makes it shine, allowing to implement a lot of business features with very few lines of code.

Over the past years of web development I have stumbled upon the FeathersJS project and have really loved it so far. It offers a lot of functionality out of the box like websockets and authentication which makes it a great alternative to real-time backends like Firebase at a fraction of the cost. There are very little node frameworks that do so much, so well with so little configuration and the only thing I see wrong with it is that it isn’t more widely used, so let me start off with why you should use FeathersJS as your API backend framework.

RESTful APIs are everywhere, powering more of the modern world than any other API architecture. REST accounts for up to 80% of APIs according to this study by ProgrammableWeb. How those APIs are built and structured can make or break a company in today’s ultra-competitive world. Poorly-designed APIs can be difficult to use, can fail when they are needed most, and are valuable targets for hackers looking for sensitive data. On the other hand, a well-designed API that utilizes best practices makes development a breeze, attracts new customers, and creates confidence among users that can boost retention rates.

As learning Mongo was the main intention, I’ve decided just to make the core app which is the backend functionality and no front end as it’s not necessary and I hate to do it.

Are you looking for a career in Backend Development? To build complete applications beyond the user-interface companies need rockstar back-end developers.

All the app data is stored and processed on the back-end. Back-end development is everything that happens behind the scenes. It is a variety of things like the databases, the business logic, the API layer and pretty much everything other than the user-interface.

The average salary for a back-end developer is $123,689 per year in the United States as of 2019. In this post, let’s learn about what it means to be a Backend Developer.

I’ve been working with react-redux, and I’m loving it, working with react is awesome, but it can get confusing really fast, so when I was introduced to redux I just instantly loved it. The thing is… when I created an application using yarn create ract-app --template redux, the app had a different syntax than the one I was taught in all the tutorials I saw on youtube, so I started playing around with the default application, and the way they do things there is cleaner and more straight forward. After a quick google search, I realized the default app uses the @redux/toolkit and I wanted to talk about it because it’s pretty great, so…

![](https://cdn.hackernoon.com/drafts/432e029tl.png)
Ever wondered how streams are working in Node.js? I had. So far I know that using streams will most certainly reduce memory usage on the server when processing large files. Instead of reading whole file into memory we stream it in chunks to whoever requested it and apply transformations to that stream if needed. That's huge benefit as it allows to avoid vertical scaling. Processing files is common task but not as common as interacting with databases and that's going to be my focus now. I'll build simple API with 2 endpoints. Both will be returning large amount of records from Postgres DB. One endpoint will stream data to the client and another will read whole data into memory and return in one chunk.

I spent the better part of a day moving a project completely off of the ORM we were using (TypeORM). Ever since I started doing web development, I’ve been using some kind of heavy abstraction on top of my database. Whether it’s Mongoose when I used MongoDB, or TypeORM when I decided to move to TypeScript and PostgreSQL. However, it turns out that ORMs and query builders aren’t so great. I used to be that person that thought ORMs and query builders did the job for me, and I used it as an excuse to not learn SQL (which is what everyone tells you NOT to do). Given the tools that exist today, I would wholeheartedly recommend doing it the opposite of how I did if you’re starting off new to these things — write your SQL stuff by hand, or with help from the tools I mention later in the post. It’ll feel really slow at first, but you’ll thank yourself later 😄

But, if a single function blocks the thread or event queue, the application performance will take a huge hit.
