30. How to Run Node.js in a Browser [Tutorial]
"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.

78. Migrating Away From Query Builders and ORMs in JavaScript or TypeScript
I spent the better part of a day moving a project completely off of the ORM we were using (TypeORM).

Whether itās 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 arenāt 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 youāre starting off new to these thingsāāāwrite your SQL stuff by hand, or with help from the tools I mention later in the post.

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.
