TypeScript updates for C++ alignment

The typings are now more strict and more aligned with the C++ interface. This means that documentation for TypeScript is more applicable to C++ and vice versa. In fact, the C++ examples are in many aspects identical to what you would write in TypeScript (ignoring syntax differences).

The biggest change is that you can no longer attach any key/value pair to WebSocket. You must define a static interface of the members up front. This means the type of WebSocket is now WebSocket<UserData> and WebSocket.getUserData() returns UserData.

Here is a complete example in TypeScript:

interface UserData {
    openDate: number;
}

uWS.App().ws<UserData>("/", {
    open: (ws) => {
        ws.getUserData().openDate = Date.now();
    },
    close: (ws, code, message) => {
        console.log("WebSocket with openDate " + ws.getUserData().openDate + " left.");
    }
}).listen(3000, (listenSocket) => {
    
});

and for comparison here is the equivalent example in C++:

struct UserData {
    time_t openDate;
}

uWS::App().ws<UserData>("/", {
    .open = [](auto *ws) {
        ws->getUserData()->openDate = clock();
    },
    .close = [](auto *ws, auto code, auto message) {
        std::cout << "WebSocket with openDate " << ws->getUserData()->openDate << " left." << std::endl;
    }
}).listen(3000, [](auto *listenSocket) {
    
});

Obviously, this only applies to TypeScript users. JavaScript users can still attach anything to anything without limitation and do not need to use getUserData(). So JavaScript code is unaffected by this change.

A bigger update

• This update contains maxLifetime, unix sockets, subscription events and many fixes and new docs additions.
• Updates uWS to v20.35.0

• Updates uWS to v20.30.0
• Adds ARMv7 binaires for Linux (unsupported)

Node.js 19 and more HTTP fixes

• uWS v20.25.0
• Dropped Node.js 14 even though it is an LTS release (due to major performance regression).

Http fixes and whitelisting Node.js 16

• Bumps uWS to v20.24.0
• While Node.js 16 performs worse than Node.js 18, it does not perform as catastrophically bad as Node.js 14. Therefore we do whitelist it again.

Blacklist Node.js 14 and 16

• Enormous performance regressions in Node.js 16 and 14 introduced by Node.js maintainers, have caused an unacceptable 75% performance decrease in uWS.js. Therefore we are forced to reject these broken versions of Node.js until Node.js maintainers get their act together and start benchmarking their changes.
• Node.js 18.10 is known to perform reasonably well, and is kept whitelisted.

Experimental HTTP/3 and much more

Updates uWS from v20.14.0 to v20.23.0 which brings many (stable) improvements. Please have a read over at https://github.com/uNetworking/uWebSockets/releases for a more complete explanation of all the changes involved.

Other than these stable changes, all platforms now ship with (still experimental) HTTP/3 support enabled. It is known to work on Linux - macOS still has some missing pieces and Windows is entirely broken for now. You can try the H3lloWorld.js example as a starting point, even though there have been more visual demos presented.

HTTP/3 support in this release is to be considered entirely broken for any production purposes, see it more as a bonus coming along the (many) stable changes.

• Wraps endWithoutBody
• Properly returns all 3 sendStatus from send calls (backwards compatible)
• Merges a few PRs updating docs, adding ESM wrapper, etc

• Updates to uWS 20.14.0.

• Updates to uWS 20.13.0.

Node.js 18, LTS-only

With this release and going forwards we will support only LTS versions of Node.js. Every year one new LTS version will be added and one old will be dropped. This means we always support a rolling set of 3 LTS versions. This release supports 14, 16 and 18.

• Adds HttpResponse pause/resume throttling

• Various fixes

• Updates uWS to v20.8.0, fixing broken compression
