ESPExpress is a lightweight and flexible web server library for ESP32, enabling developers to create efficient web-based applications with minimal effort. It provides an intuitive API for handling HTTP requests, serving static files, managing WebSockets, and enabling CORS support.

• HTTP Request Handling: Support for GET, POST, PUT, DELETE, and OPTIONS requests.
• Middleware Support: Easily add global middleware functions.
• Static File Serving: Serve files from SPIFFS or other storage.
• WebSocket Support: Handle real-time communication with WebSockets.
• CORS Support: Enable Cross-Origin Resource Sharing.
• Template Rendering: Serve dynamic HTML with variable replacements.

Include ESPExpress in your project:

#include "ESPExpress.h"

This example demonstrates how to create an ESP32 web server that controls an LED:

#include <Arduino.h>
#include <WiFi.h>
#include "ESPExpress.h"

const char* ssid     = "your_SSID";
const char* password = "your_PASSWORD";
const int ledPin = 2;
ESPExpress app(80);

void connectToWiFi() {
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
  }
}

void handleTurnOn(Request &req, Response &res) {
  digitalWrite(ledPin, HIGH);
  res.send("LED turned ON");
}

void handleTurnOff(Request &req, Response &res) {
  digitalWrite(ledPin, LOW);
  res.send("LED turned OFF");
}

void setup() {
  Serial.begin(115200);
  pinMode(ledPin, OUTPUT);
  connectToWiFi();
  
  app.get("/on", handleTurnOn);
  app.get("/off", handleTurnOff);
  
  app.listen();
}

void loop() {}

Enable real-time WebSocket communication with:

app.ws("/ws", [](uint8_t num, WStype_t type, uint8_t* payload, size_t length) {
  if (type == WStype_TEXT) {
    Serial.printf("Client %d sent: %s\n", num, payload);
  }
});

Enable CORS to allow cross-origin requests:

app.enableCORS("*");
