react-loadable VS react-i18next

React Loadable: This library makes it easy to split your React code into smaller, lazy-loaded chunks that can be loaded on demand. This can significantly improve the initial loading time of your application, especially for large and complex apps. https://github.com/jamiebuilds/react-loadable

I have a very simple React component that uses react-loadable to dynamically import another component. The code looks something akin to the following:

It's very important that you are choosing an active project instead of a dead/unmaintained project. An active project improves over time through community feedback. An unmaintained project does not move forward, fix functional bugs or patch security issues. Sometimes, a very popular package can be abandoned and go into a "frozen" state with many open issues and pull requests. It might have been a great solution in the past, but this is a sign that we have to move on. An example is react-loadable. It was a great solution for a very long time for code-splitting in React. I totally loved it. But it's stale now with many issues and PRs since 2018 (this post is written at the end of 2021). Now, if I need to split code in React, I use loadable-components, which is in active development, becoming more popular, patches bugs reported by the community, and most importantly, solves my problems. My personal advice: choose a package that's active in the last 3-6 months, with issues that are being resolved and PRs that are being merged.

> 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.

In a recent project I've been using react-i18next so I'll use its syntax for the examples, but pretty much every library works similarly.

react-i18next

i18next - You can find documentation and resources for using i18next at react.i18next.com. i18next is a popular internationalization framework for JavaScript, including React. It provides a comprehensive solution for handling translations, formatting, and more.

So far, we’ve been using a utility createLocalizedString to create and use the LocalizedString type. This utility is only really practical in unit tests. For real applications, we’ll want to use a translation function from react-i18next or next-i18next to do the heavy lifting. Then we just wrap the translation functions that are provided in order to use our type:

If you are talking about handling translations for your application, take a look at https://react.i18next.com/

I will be supporting Korean as a part of the beta. I have to look deeper into https://react.i18next.com/ in order to understand what it provides. My goal is for engineers to be able to click a single button and have localizations always up to date in their codebase, not delaying shipping a new version or having to even think about it.

With the new react-i18next version, when loading multiple namespaces, t function will infer and accept the keys for the first namespace. So this pattern is now accepted:
