Issue #947 Sometimes Row Level Security is not enough and we want to do all logic server side, then we need a way for the server to get hold onto current user token. Send JWT token in Authorization header From client, we can get session from supabase auth, then send that as Bearer in Authorization header const session = await supabase.auth.getSession().data.session const token = session.access_token const response = await fetch(url, { 'GET', headers: { Authorization: `Bearer ${token}` } }) Decode token From the nextjs API Route, we can handle all auth logic in middleware....

Issue #946 For security purposes, the auth schema is not exposed on the auto-generated API. We can make a profiles table in public namespace and mirror data from auth.users when user signs up. I need id, username and raw_user_metadata so I will mirror these columns. For easy, you can leverage Supabase SQL Editor -> Quickstarts -> User Management Starter script I don’t need Row Level Security as I manage database from server....

Issue #751 Declare data/package.json to make it into node module { "name": "data", "version": "0.1.0", "private": true, "homepage": ".", "main": "main.js" } Then in landing/package.json, use file { "name": "landing", "version": "0.1.0", "private": true, "homepage": ".", "dependencies": { "@emotion/core": "^10.0.28", "react": "^16.13.1", "react-dom": "^16.13.1", "react-image": "^2.4.0", "react-scripts": "3.4.1", "data": "file:../data" },

Issue #699 Use term ZStack like in SwiftUI, we declare container as relative position. For now it uses only 2 items from props.children but can be tweaked to support mutiple class App extends React.Component { render() { return ( <ZStack> <Header /> <div css={css` padding-top: 50px; `}> <Showcase factory={factory} /> <Footer /> </div> </ZStack> ) } } /** @jsx jsx */ import React from 'react'; import { css, jsx } from '@emotion/core' export default function ZStack(props) { return ( <div css={css` position: relative; border: 1px solid red; `}> <div css={css` position: absolute; top: 0; left: 0; width: 100%; z-index: -1; `}> {props....

Issue #658 Declare routes, use exact to match exact path as finding route is from top to bottom. For dynamic route, I find that we need to use render and pass the props manually. Declare Router as the rooter with Header, Content and Footer. Inside Content there is the Switch, so header and footer stay the same across pages import { BrowserRouter as Router, Switch, Route, Link } from 'react-router-dom' function Content() { return ( <Switch> <Route exact path="/about"> <About /> </Route> <Route exact path="/"> <Home /> </Route> <Route path='/book/:id' render={(props) => { return ( <BookDetail {....
