Understanding the Complexity of Modern Web Dev Stack (Webpack, Babel, TypeScript, React)

[@lotharmohlala851]

This is absolutely brilliant. Attaching a storyline to this was genius. This is how everyone learns; through context and use cases. Keep to this style of tutorials and this channel will sky rocket. Well done 💯

[@LachlanMiller]

Thanks Lothar!

History in tech is important. Someone needs to do a video of the history of the internet (from a network point of view)

[@menglin7432]

Now this is something I'd highly recommend any JS developer to watch

[@marianrys316]

Great stuff! Thank you ! In less than 30 min you fast-forwarded me from the 90's to modern era :)

[@LachlanMiller]

Thanks ⚡️

[@brentleemans]

Amazing video! With every part you explained WHY something was needed. This is missing in most of explanation videos on the internet. Thank you!

[@johnphillips8600]

This is the best explanation I've come across... Most videos are too long and too minified. Thank you for this ❤️

[@LachlanMiller]

Glad you found it useful!

[@narayan1509]

One of the best video I come across while searching for basics

[@paperC_CSGO]

The video I have been looking for as a junior developer - to actually try and understand the bigger picture and fundementals. Please make more of these type of videos! You are hitting a much neglected part of the web development KZbin tutorial/course/explainer videos market!

[@LachlanMiller]

Thank you! I'l do my best, glad it helped you, good luck!!

[@pkproductions1623]

This video is awesome. In just 25 minutes you explained the whole modern javascript paradox. How a simple button click in JavaScript is evolved to be so complex. Thanks a lot it made me understand concepts that are very confusing.

[@jfsimard2]

Rare you can have a history Today. Big picture is always forgotten making if difficult to get clarity. Thank you for taking the time to do it.

[@uchihai_a_h4871]

now finally all the dots got connected... brilliant mate !

[@XpressBits]

Best tutorial watched in the recent days.. Precise and no BS... you got a great teaching skills, mate! Please keep doing the videos..

[@LachlanMiller]

thanks!!

[@Speglritz]

We transpile typescript to javascript then transpile javascript to older versions of javasript for wider browser support and then the browers JIT compile the javascript it loads to run the actual code. Even without webpack, different loaders, webassembly and the other stuff going on it's complex enough.

[@michaelhashimoto1650]

This is amazing.. front end is so crazy…. Thanks for bridging the gap!

[@LachlanMiller]

Give m a like/sub, announcement soon but I'm going to be making a course/book going way deeper on frontend tooling!

this is just beautiful, i had a lot of troubles understanding what webpack, babel were, and where are they exactly used, but this video just puts everything together in a brilliant way, thank you for the video

[@LachlanMiller]

No problem, glad you found it useful!

[@ДаниелДианов]

Thank you for sharing this. I find it very informative for every new developer to understand where all things came from and why it evolved that way.

[@karanuday6803]

THIS IS AMAZING!!! I've been looking for a way to trace and understand the journey to our current setup and there's just so many different parts to it that I've just never managed to understand how all fell into place. This video explains all of that in almost an ELI5 way and covers almost everything needed! Thank you so much for this!

[@gionatha3747]

Fantastic video!

[@user-tt6nc6mo7k]

This really confused me too when I started learning web development. Now I have a great resource to refer to other people thanks! On another note, I see you have a few videos on testing using Jest, Cypress, etc. I personally am quite new to testing I understand there are different types of tests like unit testing, integration testing and end to end tests. I know what each of them are but I do not understand how they all come together in one project? Would be great if you could do a similar overview type video on how all these are implemented in a production application.

[@LachlanMiller]

Yeah this stuff is confusing - there is way more tools in the average project too, but this is the general idea. Sure, I will definitely do more content around all the different types of testing... great suggestion. One of my favorite topics.

[@deveshprasad6418]

This is amazing. You're a genius. You made it so easy to understand.

[@jhonyortiz5]

This entertaining and very eye opening when it comes to the past couple decades of web development. I hate when people use simple examples that have been simplified so much that they don't represent reality anymore. But your example was as simple as it needed to be but no more. It's really cool to see how it all really works and how it came together.

@@LachlanMiller if you ask me, I will say that given there are lot of tools out there like your video has explained, it will be good if you can make individual in depth videos of each tool and explain different configurations and what they are used for.

[@kashnigahbaruda]

As a newbie this was great. Struggled today with some jest testing presets and had absolutely no idea what was going on. I think I solved it because the error went away but I am worried the test was just skipped. Luckily I have no idea how to check which tests was skipped or not so I can go to bed without worry.

[@LachlanMiller]

Glad you got it working - skipping a test is never ideal, might be good to find out why it's failing lol. Sleep tight

[@roronoa_d_law1075]

10:37 I don't understand why webpack is needed here if the improvement is to export createElement and import it in index.js. It's impossible to to do this without webpack?

[@bakaleisanich]

Thank you! More course React!!!

[@LachlanMiller]

Main focus is around Vue, but definitely could look into some more generic tutorials on concepts that apply to both React and Vue.

[@AnthonyObi-wr6ro]

All your tutorials are always fast pace that it becomes hard for one to follow your pace

[@dimitriborgers9800]

One question: if webpack bundles everything (including third party modules) into bundle.js, doesn't that ever get too big for the browser? The Gatsby library has 1200+ modules; I would assume the bundle.js would be absolutely massive.

[@LachlanMiller]

You can load modules async, so the initial bundle isn't huge. But yes, some libs have really huge bundles - I do not think there is any upper limit, I have worked on apps with 20mb of JS. This takes a long time to parse in the browser. Things like gzip, minify, etc can make it a lot smaller.

[@KousayJebir]

awesome video man ! i do have a quick question tho , when you reached the part of using react and imported React from 'react' what tool was responsible to resolve the location of 'react' or to be more precise the actual location of the file that contains the React object

[@LachlanMiller]

Whatever runtime you are using will resolve modules using its own pre-determined rules. In this video the runtime is Node.js. You can google "node.js module resolution algorithm" or read here. nodejs.org/api/modules.html#loading-from-node_modules-folders In Node.js if the import is not a relative path, it will look in `node_modules` and then find the `package.json` for the module. In there it looks at specific fields like "main", etc.

[@KousayJebir]

@@LachlanMiller thank you very much

[@slahomar1497]

in babel.config, how wepback knows the order to use ? in case of tsx, which loader is gonna run first ?

[@LachlanMiller]

It goes in the order of the array. I think it goes last to first (weirdly enough).

[@austincodes]

And this is just the top of the iceberg

[@LachlanMiller]

I'm sorry I haven't been active in this regard. I ended up going back to study part-time and content creation, my hobby, has taken a bit of a back seat. I might just aim for some more videos in the interim... any particular topic that fascinates you, that'd you like to know more about?

[@GoatCS]

This is why WordPress is so popular. Running SQL HTML PHP and sometimes JavaScript and you don't even know it.

[@edwinquinonespardo4768]

[@marcialabrahantes3369]

webpack was built FOR react. aside from that, great content we've been building on complicated frontends for a while before webpack

[@codybontecou]

If given the choice, would you support ES5? It seems a lot of this complexity comes from supporting old browsers.

[@LachlanMiller]

Depends, last job I worked we had a lot of users on IE11 (hospitals) so we just used babel to target es5. Nowdays browsers can actually load es modules natively via , so depending on your project you might not even need webpack, just a simple typescript build that exports modules, but I think a pre-configured setup (vue cli, create react app) is probbly the way to go.
