Sending Calendar Invites Functionality

Building upon the setup from the first path of this article, let's dive straight into the code for sending calendar invites!

import { useState } from "react";
import { smtpexpressClient } from "../../services/smtp";

const CalendarInvite = () => {
  const [loading, setLoading] = useState(false)
  const [eventTitle, setEventTitle] = useState("");
  const [email, setEmail] = useState("")
  const [startDateInvite, setStartDateInvite] = useState("")
  const [endDateInvite, setEndDateInvite] = useState("")
  const [location, setLocation] = useState("")
  const [url, setUrl] = useState("")
  const [meetingLocation, setMeetingLocation] = useState("")
  const [description, setDescription] = useState("")

  const handleSubmit = async (e: any) => {
    e.preventDefault();
    setLoading(true);    

    try {
      await smtpexpressClient.sendApi.sendMail({
        subject: "Calender Invite",
        message: "Please find the attached calendar invite.",
        sender: {
          email: import.meta.env.VITE_SMTP_PROJECT_SENDER_EMAIL,
          name: "Alex Johnson", // Full name of the sender for personalization
        },
        recipients: {
          email: email, 
          // name: "John Doe", // name of the recipient for personalization
        },
        calendarEvent: {
          title: eventTitle,
          startDate: new Date(startDateInvite),
          endDate: new Date(endDateInvite),
          organizer: "alex.johnson@company.com", //  use the email of the event organizer
          location: location === "remote" ? url : meetingLocation,
          url: url, // meeting link
          description: description,
        },
      });

      // Notify user of successful submission
      alert("Please check your email to view the sent message");
      setLoading(false)

      // clear your form fields.
    } catch (error) {
      console.log(error);
      alert("Oops! Something went wrong. Please try again later.");
      setLoading(false)
    } finally{
      setLoading(false);
    }
  }

  return (

        {location === "remote" && (
          <div>
            <label>URL Link</label>
            <input
              required

              value={url}
              onChange={(e) => setUrl(e.target.value)}
              placeholder="Meeting Link"
            />
          </div>
        )}

        {location === "physical" && (
          <div>
            <label>Enter Location</label>
            <input
              required
              type="text"
              value={meetingLocation}
              onChange={(e) => setMeetingLocation(e.target.value)}
              placeholder="Meeting Location address"
            />
          </div>
        )}

        <button>{loading ? "Loading..." : "Send Calender Invite 🚀"}</button>
      </form>
    </div>
  );
}

export default CalendarInvite

The code above does the following:

State Management: Uses useState for form inputs and loading state.
Form Submission: handleSubmit() function prevents default, sets loading, sends email, and handles success/failure alerts.
Renders Form: includes input fields for email, event title, dates, location, URL (if remote), meeting location (if physical), and description.
Conditional Rendering: Shows URL if remote, meeting location if physical.
Submit Button: Displays "Loading..." during form submission.

Here is the User Interface layout with pre-filled details:

On clicking the Send Email button, you should get an alert saying Please check your email to view the sent message. You would see this if you correctly configured the project.

We then get the Calendar invite in our mail, here's proof of it below:
