Each user get's their own database, courtesy of Cloudflare Durable Objects.</p> <p>It's barebones, but it was a fun little project.</p> <h2> Demo </h2> <p>Screenshots are below - it's email, so not much to demo. I've redacted the inbound email address to protect my Postmark free account email limit, but if the judges reach out I'll share the email address to interact with the app.</p> <p>Email a link:<br> <a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F4hh2b1tigd3rs4l0gxg8.jpg" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F4hh2b1tigd3rs4l0gxg8.jpg" alt="Add a link" width="800" height="746"></a></p> <p>Link added reply:<br> <a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F0w7luqo5eh2p15xb9x09.jpg" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F0w7luqo5eh2p15xb9x09.jpg" alt="Link added" width="800" height="246"></a></p> <p>Search for a link:<br> <a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F4vhdhgmgpvtaaca31tbs.jpg" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F4vhdhgmgpvtaaca31tbs.jpg" alt="Search for a link" width="800" height="745"></a></p> <p>Search result reply:<br> <a href="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fgai8hk51ln3gnlugjum7.jpg" class="article-body-image-wrapper"><img src="https://media2.dev.to/dynamic/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fgai8hk51ln3gnlugjum7.jpg" alt="Search result" width="800" height="321"></a></p> <h2> Code Repository </h2> <p><a href="https://github.com/leesus/postmarks" rel="noopener noreferrer">https://github.com/leesus/postmarks</a></p> <h2> How I Built It </h2> <p>The app makes use of Postmarks Inbound and Transactional streams, to interact with a Cloudflare Worker, backed by Vectorize and Durable Objects.
