react-hot-loader VS Next.js

React Hot Loader - Tweak React components in real time

Developer Experience - There are a number of tools that improves the development experience with React. React Developer Tools is a browser extension that allows you to inspect your component, view and manipulate its props and state. Hot reloading with webpack allows you to view changes to your code in your browser, without you having to refresh the browser. Front end development involves a lot of tweaking code, saving and then refreshing the browser. Hot reloading helps you by eliminating the last step. When there are library updates, Facebook provides codemod scripts to help you migrate your code to the new APIs. This makes the upgrading process relatively pain-free. Kudos to the Facebook team for their dedication in making the development experience with React great.

I am considering how to make my compiler (which outputs JavaScript), output patch changes, which somehow update the server or browser with the code changes, so you don't have to shutdown/restart the server or refresh the page. I was going to take a look at the react-hot-loader source code, but it's a little too abstract, it will take a while / few days at least to start to grok.

I am starting to look through the source of react-hot-loader, but it is no insignificant beast. Can someone explain at a high level how this is implemented, just in enough detail so one could reason about how to reimplement this functionality in another programming language?

I'm using react-hot-loader and I'm very confused about its example code:

Next.js is a powerful React framework that enables developers to build server-rendered applications, static websites, and more. It's designed for production and provides features like automatic code splitting and optimized prefetching.

https://github.com/vercel/next.js/discussions/27666 One of them said 'renaming folder to uppercase' might cause trouble. git might not recognize case-sensetive changes by default.

Next.js has long cemented itself as one of the front runners in the web framework world for JavaScript/TypeScript projects so we’re going to be using that. More specifically we’re going to be using V14 of Next.js which allows us to use some exciting new features like Server Actions and the App Router.

Web frameworks like Next.js will usually include this feature, but do check that they set the caching headers correctly!

Vite and Next.js are both top 5 modern development framework right now. They are both great depending on your use case so we’ll discuss 4 areas: Architecture, main features, developer experience and production readiness. After learning about these we’ll have a better idea of which one is best for your project.

> It’s important to be aware of what you are getting if you go with React, and what you are getting is a far cry from what a framework would offer, with all the corresponding pros and cons.

Would you like to elaborate on that?

In my experience, with something as great, size/ecosystem-wise as React, there will almost always be at least one "mainstream" package for whatever you might want to do with it, that integrates pretty well. Where a lot of things might come out of the box with a framework, with a library I often find myself just needing to install the "right" package, and from there it's pretty much the same.

For example, using https://angular.io/guide/i18n-overview or installing and using https://react.i18next.com/

Or something like https://angular.io/guide/form-validation out of the box, vs installing and using https://formik.org/

Or perhaps https://angular.io/guide/router vs https://reactrouter.com/en/main

Even adding something that's not there out of the box is pretty much the same, like https://primeng.org/ or https://primereact.org/

React will typically have more fragmentation and therefore also choice, but I don't see those two experiences as that different. Updates and version management/supply chain will inevitably be more of a mess with the library, admittedly.

Now, projects like Next https://nextjs.org/ exist and add what some might regard as the missing pieces and work well if you want something opinionated and with lots of features out of the box, but a lot of those features (like SSR) are actually pretty advanced and not always even necessary.

Next.js: For the website and the admin dashboard

Until the time of writing, there is no official example of how to enable runtime environmental variables in a Dockerized Next.js app, as utilizing unstable_noStore would only dynamically evaluate variables on the server (node.js runtime). There is also an interesting discussion regarding this topic on GitHub.

next.js is a very popular React framework. remix-adonisjs includes more functionality through the AdonisJS backend ecosystem, and should be easier to self-host and self-manage.
