CppCon 2018: Vinnie Falco “Get rich quick! Using Boost.Beast WebSockets and Networking TS”

—

Do you want to make a lot of money? You'll see some examples of free browser and server based WebSocket programs which have earned their respective individual authors tens of millions of dollars in no time at all. Perhaps after seeing this talk in person, you'll write the next massively successful WebSocket app!

The WebSocket protocol powers the interactive web by enabling two-way messaging between the browser and the web server. The Boost.Beast library implements this protocol on top of the industry standard Boost.Asio library which models the Networking Technical Specification proposed for the ISO C++ Standard.

This presentation introduces Networking TS concepts and algorithms, how to read their requirements, and how to use them in your programs. We will build from scratch a multi-user chat server in C++11 using Beast, and the corresponding browser-based chat client in HTML and JavaScript. No prior knowledge or understanding of Beast or Asio is required, the talk is suited for everyone.

This is the best talk I've seen that spanned a lot of concepts in a clear way. 👏👏👏

[srcmake]

Your talk was god-tier dude. The entire presentation was amazing, on every level.

[nancyfalco]

Its wonderful to hear the voice of my wonderful Vinnie. My child prodigy and creator of Bear Share. I miss you so m u c h!

[andrelucas]

That was worth a thousand pages of documentation, thank you!

[rmpowell]

Really great video. So much content that I found myself having to frequently pause and go back to review. Powerfully simple.

[mzimbres]

Another great talk from Vinnie. With the networking TS and Beast I would not be surprised to see C++ taking some place from Erlang in realtime communication. Thanks to Vinnie for making this library available to us.

[alexeiz]

Damn! Networking in C++ used to be complicated. Now everyone is going to know how to do that in relatively few lines of code.

[jordan]

That was quite a rich talk and just what I was looking for. I was really confused with the examples online. That transfer of ownership paradigm with the shared from this was very unintuitive to me. I like the JavaScript lessons and how everyone was so amazed at how easily it was to do the client socket in a higher level language.

[CristianMarletta]

Great talk, super clear and Vinnie keeps it always interesting.

[jiwang]

great material! thanks for your great work!

[fourscoreand]

Thanks for all your great work, Vinnie.

[FabienFabienB]

Amazing presentation. It requires multiple listen to fully grasp the full extent which is really necessary to mast low level websocket in C++. Curious about Beast alternate implementation and how they fare in terms of performance / ease of use.

30 seconds deadline for session deletion because i didn't want to use shared pointers. i learned something new today.

[starriet]

around 20:40) I think `while(N--)` should be `while(--N)`, since the intent is making the vector contain N-1 threads, not N threads.
Anyway, thanks for the wonderful talk!

[teras]

**claps** great talk! love your code and libs Vinnie !

[juryk]

Thanks for making this video! So helpful.

Why does ConstBufferSequence require CopyConstructible instead of just MoveConstructible? How many coexistent copies does the write method create internally?

[jaysistar]

I would really like a talk about Boost.Beast with the Networking TS and the Coroutines TS. If there isn't one, I think we will all get too comfortable with JavaScript async/await. C++ needs coroutines here to simplify the lifetime of the state, not just the control flow, using an allocator that allocates out of a a std::array in the coroutine frame.

It would be nice if someone would make this not-yet-done talk.

[AYetau]

Could someone please explain to me the reasons of the reoccurring Javascript bashing here at cppcon talks? Or how should it be understood if not bashing? Is it just a popular humorous handling of other languages in general, more like a running gag? But if I should keep my hands away from JavaScript in productive code, for what reasons and what's the better alternative?

[bsuperbrain]

it is 2022 and still no standardized networking in c++
