Coding a Web Server in 25 Lines - Computerphile

Just how simple can a web server be? Laurence Tratt, Shopify / Royal Academy of Engineering Research Chair in Language Engineering at Kings College London builds it up.

This video was filmed and edited by Sean Riley.

The joy of modern programming languages. Listening on a socket in just one line.

I loved Laurie’s smile each time he wrote something he knew was absolutely dodgy!

[uuu]

He is a gift that keeps on giving

A fundamental explanation of making a simple webserver in 25 LOC for easy understanding of its components

A lecturer that
1. Uses Rust
2. Uses a framework laptop
3. USES NEOVIM

very nice

Programming Rust on a Framework laptop running OpenBSD. Absolutely based.

I had this professor for a few lectures in my undergrad during covid. He was very enthusiastic, funny and explained things really well. He was also was explaining concepts with his neovim + rust setup. Happy to see him again on computerphile!

[OldShatterham]

Honestly I didn't expect the fundamentals of HTTP to be so easy. This sort of "from-the-ground-up" approach was really fun to watch!

[dylanmeeks]

Rust user? Framework laptop owner? Based prof.

You can tell this guy loves what he does. Thanks for the video!

The funny thing is, there's an async tutorial in the Rust Book that explains how to use threads with a web server do handle 4 workers. If I remember correctly it's not even 10 lines more. Would've been a cool addition!

Don't know if it's a coincidence, but the code really reminded of the one in the first chapters of the Rust Book – Building a Multithreaded Web Server. I've just been reading it a couple of weeks ago, and can definitely recommend taking a look if you're interested! Though it's worth mentioning that the code does contain some difficult Rust

[TheHenrik]

Great format for explaining web servers. Those 17 minutes flew by

[halfsourlizard]

'I am abusing this monstrously.' == always the sign of well-written code.

[Sonex]

This was awesome. I was a programmer, now a DBA. Having someone explain code like this is what a learning experience should be.

[Lurco]

Fantastic content, that's what I was always missing in the "basic" server setup - the way the server actually functions!

[lanatrzczka]

Even before the rest was completed, just the bit that sent back "Hello Computerphile" was totally amazing to me.

[Norman_Fleming]

it is important to remember that whichever end you are writing, you need to consider the other end a bad actor or buggy AF.

[vincei]

You can build the web server in one line of code if you put your 25 lines of code in a library. 😂

[linuxguy]

Nice! One of my first projects was writing my own webserver in Java, later added PHP support and used it to host my website.

[joaopedrorocha]

I love this guy's computherphile videos! He's always very clear and bring practical stuff.

Awesome video, great job at explaining the questions asked. Absolute chad energy Laurence
