ESP Async WebServer

Asynchronous HTTP and WebSocket Server Library for ESP32.
Supports: WebSocket, SSE, Authentication, Arduino Json 7, File Upload, Static File serving, URL Rewrite, URL Redirect, etc.

This fork is based on yubox-node-org/ESPAsyncWebServer and includes all the concurrency fixes.

Changes in this fork Copy Chapter

• Removed SPIFFSEditor
• Deployed in PlatformIO registry and Arduino IDE library manager
• CI
• Some code cleanup
• SSE_MAX_QUEUED_MESSAGES to control the maximum number of messages that can be queued for a SSE client
• write() function public in AsyncEventSource.h
• Arduino Json 7 compatibility and backward compatible with 6 and 6 (changes in AsyncJson.h). The API to use Json has not changed. These are only internal changes.
• WS_MAX_QUEUED_MESSAGES: control the maximum number of messages that can be queued for a Websocket client
• Resurrected AsyncWebSocketMessageBuffer and makeBuffer() in order to make the fork API-compatible with the original library from me-no-dev regarding WebSocket.
• #5 (@vortigont): set real "Last-Modified" header based on file's LastWrite time
• #13 (@tueddy): Compile with Arduino 3 (ESP-IDF 5.1)
• #14 (@nilo85): Add support for Auth & GET requests in AsyncCallbackJsonWebHandler
• Added setAuthentication(const String& username, const String& password)
• Added StreamConcat example to shoiw how to stream multiple files in one response
• Remove filename after inline in Content-Disposition header according to RFC2183
• Depends on mathieucarbou/Async TCP @ ^3.1.4
• Arduino 3 / ESP-IDF 5.1 compatibility
• Added all flavors of binary(), text(), binaryAll() and textAll() in AsyncWebSocket
• Added setCloseClientOnQueueFull(bool) which can be set on a client to either close the connection or discard messages but not close the connection when the queue is full

Usage and API stays the same as the original library.

`AsyncWebSocketMessageBuffer` and `makeBuffer()` Copy Chapter

The fork from yubox-node-org introduces some breaking API changes compared to the original library, especially regarding the use of std::shared_ptr<std::vector> for WebSocket.

This fork is compatible with the original library from me-no-dev regarding WebSocket, and wraps the optimizations done by yubox-node-org in the AsyncWebSocketMessageBuffer class.
So you have the choice of which API to use.
I strongly suggest to use the optimized API from yubox-node-org as it is much more efficient.

Here is an example for serializing a Json document in a websocket message buffer. This code is compatible with any forks, but not optimized:

void send(JsonDocument& doc) {
  const size_t len = measureJson(doc);

  // original API from me-no-dev
  AsyncWebSocketMessageBuffer* buffer = _ws->makeBuffer(len);
  assert(buffer); // up to you to keep or remove this
  serializeJson(doc, buffer->get(), len);
  _ws->textAll(buffer);
}

Here is an example for serializing a Json document in a more optimized way, and compatible with both forks:

void send(JsonDocument& doc) {
  const size_t len = measureJson(doc);

#if defined(ASYNCWEBSERVER_FORK_mathieucarbou)

  // this fork (originally from yubox-node-org), uses another API with shared pointer that better support concurrent use cases then the original project
  auto buffer = std::make_shared<std::vector<uint8_t>>(len);
  assert(buffer); // up to you to keep or remove this
  serializeJson(doc, buffer->data(), len);
  _ws->textAll(std::move(buffer));

#else

  // original API from me-no-dev
  AsyncWebSocketMessageBuffer* buffer = _ws->makeBuffer(len);
  assert(buffer); // up to you to keep or remove this
  serializeJson(doc, buffer->get(), len);
  _ws->textAll(buffer);

#endif
}
