How to Seamlessly Enable Client-Side Emailing with JavaScript?

Client-Side Emailing with JavaScript

Challenge: Enabling users to send templated emails through their local mail clients, avoiding server-side email sending and empowering users to edit the message before it's sent.

Solution 1 (Method Used by the Poster):

Utilizing a mailto link with encoded subject and body parameters allows users to open a draft email in their local mail client. While convenient, this solution faces limitations for extremely long email bodies.

Improved Solution:

To overcome the length limitation and provide a seamless user experience, consider the following enhanced approach:

1. Using Composing API: Modern browsers support the navigator.clipboard.writeText or document.execCommand APIs, which enable programmatic access to the user's clipboard. This allows the body content to be set directly into the clipboard.
2. Browser Compatibility Checks: To ensure cross-browser compatibility, perform compatibility checks for the navigator.clipboard API and fallback to document.execCommand if necessary.
3. Custom Email Client Support: If the device or browser lacks native email client support, provide a pre-composed email message that the user can copy and paste into their preferred client.
4. User Interface Enhancements: Consider implementing a variety of predefined templates or editing tools to enhance user convenience and minimize the need for manual editing.
