+
+JS library for a HTTP Requests
+
+## usage
+
+Example usage with JSON data:
+
+	var apiUrlJson = "https://example.com/api/json";
+	var requestDataJson = {
+		key1: "value1",
+		key2: "value2"
+	};
+
+	sendHttpRequest(apiUrlJson, "POST", requestDataJson, function (error, response) {
+		if (error) {
+		    console.error("Error:", error);
+		}
+		else {
+		    console.log("JSON Response:", response);
+		}
+	}, "application/json");
+
+Example usage with non-JSON data (e.g., form data):
+
+	var apiUrlFormData = "https://example.com/api/formdata";
+	var formData = new FormData();
+	formData.append("key1", "value1");
+	formData.append("key2", "value2");
+
+	sendHttpRequest(apiUrlFormData, "POST", formData, function (error, response) {
+		if (error) {
+		    console.error("Error:", error);
+		}
+		else {
+			console.log("Form Data Response:", response);
+		}
+	}, "multipart/form-data");
