Show HN: React-meta-SEO – Rebuilding SEO for React 19 (3KB, no providers) I’m a computer engineering student at SPPU. While working on a project with React 19, I realized that the standard libraries we use for SEO (like React Helmet) are still doing things the "old" way. The Problem: Older libraries use a trick called "side effects" to change your page title and meta tags after the page has already loaded. This can cause the title to flicker or make the site feel a bit slower because the browser has to do extra work. The Solution: React 19 added a built-in feature that lets it move tags to the top of the page (the ) automatically. I built react-meta-seo to make this new feature easy to use for everyone. Why it’s simpler for developers: No "Provider" needed: You don't have to wrap your whole app in a special component. It just works wherever you drop it. Tiny size: It’s under 4KB. For comparison, legacy options are usually 15KB or more. No more broken Google data: It checks your Google Search data (JSON-LD) automatically to make sure it’s formatted correctly. Built-in Preview: I added a tool so you can see what your site will look like on Twitter or Facebook while you're still coding. Simple Sitemap Tool: It includes a command-line tool to make your sitemap.xml for you. I wanted to build something that used the new React 19 features to make SEO faster and easier to set up. I’d love to get some feedback on the code! GitHub: https://ift.tt/HMF1lWD https://ift.tt/J3T6Ng1 January 25, 2026 at 12:07AM
