  • Punk: Fully Authed
    This guide builds one application with all of those doors on it, from punk new to a passing test suite, using four pieces of the Punk ecosystem: Punk::Auth for the identity and the single-use tokens, Punk::Plugin::Mailer to send the tokens through Resend, Punk::Plugin::TOTP for the second factor, and Punk::Plugin::OAuth2 for GitHub and Google. - Source: dev.to / 18 days ago
  • I Built an Open-Source project. It Became the Official MailChannels JS SDK
    What started as a small Nuxt integration eventually became a full Node.js and TypeScript SDK for MailChannels. Along the way, I learned a lot from the Vue, Nuxt, and UnJS ecosystems, took inspiration from other developer-focused tools such as Resend, and eventually had the opportunity to join MailChannels and get the project adopted and officially maintained. - Source: dev.to / 27 days ago
  • Getting Your Writing Seen Beyond Your Own Site
    Two practical pieces. First, you need a transactional sender that can do broadcasts. I use Resend because the API is good, the React Email integration is good, and the dashboard is sane. Postmark and AWS SES work fine too. Second, on every publish, send a broadcast to your audience. This is the closest thing you have to a guaranteed reader. - Source: dev.to / 3 months ago
  • How to Send Transactional Emails with Vue and Resend
    Resend has quickly become the default way to send email from modern applications. The API is clean, the deliverability is good, and the developer experience is impressive. But Resend only handles sending emails. It provides a html field and you produce the HTML that you've ensured is compatible with Gmail, Outlook, and the many other email clients. - Source: dev.to / 3 months ago
  • Adding comments to a static Astro blog with Netlify Forms
    Netlify/functions/comment-handler.js is triggered by a Netlify outgoing webhook Whenever a new submission hits the blog-comments queue. It sends an HTML email Via Resend (the same delivery layer used for new post notifications) containing the comment text and two HMAC-SHA256-signed action links:. - Source: dev.to / 4 months ago
