ESP32 HTTP web server: Serving external JavaScript file

In this tutorial we will learn how to serve an external JavaScript file to be referenced by a HTML file, using the ESP32. The ESP32 will be running the Arduino core and the HTTP async web server libraries. The tests were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board.

ESP32 Arduino web server: Sending data to JavaScript client via websocket

In this tutorial we will check how to setup a HTTP web server on the ESP32, which will have a websocket endpoint and will serve a HTML page. The HTML page will run a simple JavaScript application that will connect to the server using websockets and periodically receive simulated temperature measurements from the server.

The tests from this tutorial were performed using a DFRobot’s ESP32 module integrated in a ESP32 development board.
