This guide breaks down what changes at scale, <b>define SLAs/SLOs, understand SSR vs SSG caching, and stop relying on a single instance</b>. High-impact wins include adding a <b>CDN with proper cache headers</b>, moving to <b>horizontal scaling with shared Redis cache</b>, introducing an <b>API Gateway for auth</b>, and offloading uploads to <b>blob storage</b>. The takeaway, you don’t need a rewrite, just smarter architecture as your app grows. </p></td></tr><tr><td class="dd" align="left" style="padding:0px 15px;text-align:left;word-break:break-word;"><p style="mso-line-height-alt:150.0%;"> 🤖 <span style="text-decoration:underline;"><b><a class="link" href="https://link.mail.beehiiv.com/v1/c/8rZo5ed91syGovNMF1sFEdT7hJuPvE9DXfLGLLwTfn5BkIEmuA68TYTwOrNP%0AgMtz%2BewhRZZbFMNE331mazqsBFFzizWr72CzSefoCCH9hA3DR%2Bx06G2Ym3Ei%0A1ft5x18Iper%2B4JlSn1eyPwY2IVNpYj8p5qJqWjl8yWjuYumAUbNVJRHv1DMu%0AnXpNJVS%2FnOAd%0A/c808c21c1edc452e" target="_blank" rel="noopener noreferrer nofollow"><span>The Recent React & Node.js CVEs?

According to Winfunc, the system handled <b>codebase analysis, threat modeling, exploit generation, and PoC verification</b> end-to-end before responsible disclosure. The vulnerabilities were real and patched, but the bigger shift is this.

Over time, he moved to <b>delegating “slam dunk” tasks</b>, running agents at the end of each day, and engineering better tooling (“harness engineering”) so agents catch their own mistakes.
