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 {....

Issue #654 Use shelljs to execute shell commands, and fs to read and write. In public/index.html specify some placeholder and we will replace those in our script const fs = require('fs'); const shell = require('shelljs') let indexHtml = fs.readFileSync(publicIndexHtmlPath, 'utf8') indexHtml = indexHtml .replace('CONSTANT_HTML_TITLE', `${app.name} - ${app.headline.title}`) .replace('CONSTANT_HTML_META_DESCRIPTION', app.headline.text) fs.writeFileSync(publicIndexHtmlPath, indexHtml) // build shell.cd('projects/my_react_app') shell.exec('npm run build') // copy shell.exec(`cp -a projects/my_react_app web_server/public`)
Issue #654 A good landing page is one of the most crucial part of a successful launch. Recently I started creating landing pages for my apps, I was lazy that I ended creating a white label React app as a landing template and then write a script to build multiple similar pages. Here are a few examples, at first the pages share same look and feel, but we can add more configuration parameters later on....

Issue #648 In a similar fashion to plain old javascript, note that href needs to have valid hash tag, like #features <a href='#features' onClick={() => { const options = { behavior: 'smooth' } document.getElementById('features-section').scrollIntoView(options) }} > Features </a> Updated at 2020-05-06 08:36:21
Issue #647 emotion can be used in framework agnostic or with React. To use with React, follow https://emotion.sh/docs/introduction#react npm i @emotion/core Note that you must have /** @jsx jsx */ at the top of the file, and the unused jsx in import is a directive for JSX to work properly // this comment tells babel to convert jsx to calls to a function called jsx instead of React.createElement /** @jsx jsx */ import { css, jsx } from '@emotion/core' const color = 'white' render( <div css={css` padding: 32px; background-color: hotpink; font-size: 24px; border-radius: 4px; &:hover { color: ${color}; } `} > Hover to change color....
Issue #352 For a normal electron app created with npm init, we can use all features of ES6, but not the JSX syntax for React. We can use just Babel to transpile JSX, as used in IconGenerator .babelrc { "plugins": [ "transform-react-jsx-source" ], "presets": ["env", "react"] } And in package.json, call babel to transpile src to dist "main": "dist/main.js", "scripts": { "start": "npm run babel && electron .", "babel": "babel ....
