Welcome to my "Week in Review" series. Each week I will share what I discovered, learned, and tested with you. Let's take a look at what I got this week.
As mentioned in my last review, this one and also the next one is shorter. Afterward, you can find my Week in Review here again in the usual length and scope. If you have tools you would like me to test, please let me know. I would be glad to hear from you. Until then I hope you enjoy reading.
This topic alone would be worth a blog post of its own. But for today I'll leave it to make you curious and share a link with more examples and docs.
It has never been more important than today to optimize the speed and size of your website, especially on mobile devices. Getting a top Google Lighthouse Index score is very important for SEO. A lot can be achieved with Lazy Loading Images, Responsive Images, CDNs, Caching, Minification, and Uglification.
Do you want to know more about it? Do you want to know how it works with server-side rendering? I got you covered. I have created (actually forked) an example app (template repository) with code splitting, lazy loading components per route, and TypeScript.
There were some "aha" moments when I looked at the official SSR example and bundling docs (with Webpack). A few details were not well documented in my opinion. For this reason, I link some of my learnings here. Hopefully, this makes it easier for you to get started.
tsconfig.json: When you use both
moduleis set to
esnext! It took me quite some time to figure that out.
ts-loaderneeds to be properly configured with a custom ´getCustomTransformers`. You also need to add LoadablePlugin to the plugins.
webpack.server.js: If you bundle the server app, make sure the libraryTarget is set to commonjs2 and @loadable/component is excluded from the bundle.
If you have more questions, let me know on Twitter.

I paused reading "We Are All Leaders: Leadership is not a position, it's a mindset" by Fredrik Arnander and finished "Ego is the Enemy" by Ryan Holiday instead. It is an exciting book about the influence of the ego on our success, our environment, and how we can and should deal with it. Have you read it too?
