feat(examples): add local components via idf_component.yml
Specifying all the dependencies (managed and local) in the manifest
makes it easier for users to see every component the example
depends on.

Async Requests Handlers HTTPD Server Example

The Example demonstrates how to handle multiple long running simultaneous requests within the HTTPD server. It has the following URIs:

1. URI \long for demonstrating async requests running in the background
2. URI \quick for demonstrating that quick requests are still responsive
2. URI \ index page

How to use example

Hardware Required

  • An ESP-Dev-Board (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
  • A USB cable for power supply and programming

Configure the project

idf.py menuconfig
  • Open the project configuration menu (idf.py menuconfig) to configure Wi-Fi or Ethernet. See "Establishing Wi-Fi or Ethernet Connection" section in examples/protocols/README.md for more details.

Build and Flash

Build the project and flash it to the board, then run monitor tool to view serial output:

idf.py -p PORT flash monitor

(Replace PORT with the name of the serial port to use.)

(To exit the serial monitor, type Ctrl-].)

See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
