ESP WebSockets Sample

This sample demonstrates writing large, streaming response without blocking, buffering or consuming excessive memory. This sends a large file as a single web socket message using multiple frames.

The sample is implemented as an ESP controler with one action. A test web page initiates the client WebSocket request to retrieve the file. To run, browse to:

http://localhost:8080/index.html

Requirements

• Appweb

To build:

make

To run:

make run

The server listens on port 8080. Browse to:

 http://localhost:8080/index.html

This opens a web socket and and listens for WebSocket data sent by the server. It will display the received data in the browser window.
