Pre-built Auth UI for React

In plain words

Pre-built Auth UI for React is a component library that enables developers to add user authentication to React applications through Supabase Auth. It provides ready-made interface elements for login and signup flows, with customizable themes and extensible styling options to match application branding. The tool is designed for developers building React applications who want to implement authentication without creating UI from scratch.

Step-by-step guide to migrating your app to the new SSR package

The new ssr package takes the core concepts of the Auth Helpers and makes them available to any server language or framework. This page will guide you through migrating from the Auth Helpers package to ssr . The new ssr package exports two functions for creating a Supabase client. The createBrowserClient function is used in the client, and the createServerClient function is used in the server. Read the Creating a client page for examples of creating a client in your framework and our migration guidefrom supabase.com

  Talanoa▲340

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I 3D scanned the interior of the Great Pyramid at Giza▲1,752

  Hey HN, I 3d scanned the interior of the Great Pyramid / Khufu's pyramid for the Giza Project this summer and just finished the guided version to share. Would love feedback and/or problems you encounter. I used both a Leica BLK 360 and Matterport Pro 2 to do the scanning and the Matterport SDK for the web viewer. Matterport's web display with Three.js has been the most accessible to a wide audience in the past (previous iterations are in Unity and Unreal, but difficult to download over slower connections). I've been interviewing social studies teachers around the 6th grade level to…

  America – Road Trip Simulator▲663

  APIs are a little like the open road—always waiting, full of opportunity, but hardly utilized. So here’s America, composed of several APIs that paint a vivid, real-time picture of a good old-fashioned road trip. Get local classifieds and photos. Tune into local radio stations. Talk wit other drivers. And more. Exploring the country by car was an invaluable experience for me during my time in the states. I’ve since moved to Barcelona, and find myself missing the territory. This is my attempt at recreating the magic.
