Combining Java's SendGrid with Dynamic HTML Email Templates

Using SendGrid to Implement Dynamic Email Templates in Java

Java and HTML Handling

// Import SendGrid and JSON libraries
import com.sendgrid.*;
import org.json.JSONObject;
// Method to replace newlines with HTML breaks
public static String convertToHtml(String text) {
    return text.replaceAll("\n", "<br/>");
}
// Setup SendGrid API Key
String apiKey = "YOUR_API_KEY";
SendGrid sg = new SendGrid(apiKey);
// Create a SendGrid Email object
Email from = new Email("your-email@example.com");
String subject = "Sending with SendGrid is Fun";
Email to = new Email("test-email@example.com");
Content content = new Content("text/html", convertToHtml("Hello, World!\nNew line here."));
Mail mail = new Mail(from, subject, to, content);
// Send the email
Request request = new Request();
try {
    request.setMethod(Method.POST);
    request.setEndpoint("mail/send");
    request.setBody(mail.build());
    Response response = sg.api(request);
    System.out.println(response.getStatusCode());
    System.out.println(response.getBody());
    System.out.println(response.getHeaders());
} catch (IOException ex) {
    ex.printStackTrace();
}

Using Frontend JavaScript to Manage Email Text Inputs

JavaScript Text Processing

// JavaScript function to capture text input
function captureInput() {
    let inputText = document.getElementById('inputField').value;
    sendDataToServer(inputText);
}
// Function to send data to the Java backend via AJAX
function sendDataToServer(text) {
    $.ajax({
        url: 'http://yourserver.com/send',
        type: 'POST',
        contentType: 'application/json',
        data: JSON.stringify({ emailText: text }),
        success: function(response) {
            console.log('Email sent successfully');
        },
        error: function(error) {
            console.log('Error sending email:', error);
        }
    });
}
// HTML input field
<input type="text" id="inputField" placeholder="Enter text here">
<button onclick="captureInput()">Send Email</button>
