This is a NOP for existing usecases. At the moment the only implemented transport for serialized SS is wsi, it's typically used with Unix Domain Sockets, but it also works over tcp the same. It generalizes the interface between serialized chunks and the transport, separately for client and proxy. The wsi transport is migrated to use the new transport ops structs. It will then be possible to "bring your own transport", so long as it is reliable, and in-order, both for proxy and client / sspc. We also adapt minimal-secure-streams-binance to build the -client variant via SS proxy as well. LWS_ONLY_SSPC is added so libwebsockets can be produced with just sspc client support even for tiny targets. A new embedded minimal example for rpi pico is also provided that demonstrates using Serialized SS over a UART to an SS proxy, to implement the SS Binance example on the pico, even though it has no networking itself. |

Libwebsockets
Libwebsockets is a simple-to-use, MIT-license, pure C library providing client and server for http/1, http/2, websockets, MQTT and other protocols in a security-minded, lightweight, configurable, scalable and flexible way. It's easy to build and cross-build via cmake and is suitable for tasks from embedded RTOS through mass cloud serving.
It supports a lot of lightweight ancilliary implementations for things like JSON, CBOR, JOSE, COSE, and supports OpenSSL and MbedTLS v2 and v3 out of the box for everything. It's very gregarious when it comes to event loop sharing, supporting libuv, libevent, libev, sdevent, glib and uloop, as well as custom event libs.
100+ independent minimal examples for various scenarios, CC0-licensed (public domain) for cut-and-paste, allow you to get started quickly.
There are a lot of READMEs on a variety of topics.
We do a huge amount of CI testing per push, currently 582 builds on 30 platforms. You can see the lws CI rack and read about how lws-based Sai is used to coordinate all the testing.
News
v4.3 is released

Lws work retrospective
The initial commit for lws will have been 11 years ago come Oct 28 2021, it's been a lot of work. There are a total of 4.3K patches, touching 800KLOC cumulatively (this is not the size in the repo, but over the years, how many source lines were changed by patches).
Gratifyingly, it turns out over the years, ~15% of that was contributed by 404 contributors: that's not so bad. Thanks a lot to everyone who has provided patches.
Today at least tens of millions of devices and product features rely on lws to handle their communications including several from FAANG; Google now include lws as part of Android sources.
