React SSR, SSG, SPA - History & Colour

SSR History & Colour

  • Three React approaches
    • SPA Single Page Applications
    • SSR Server Side Rendering
    • SSG Static Site Generation

    • SPA - Single Page Applications :: fat client, API
      • Send plain javascript that does on everything on client
      • SEO nightmare
  • Google Crawler is starting to execute JavaScript

function mapValues(obj, fn) {
return Object.keys(obj).reduce((result, key) => {
result[key] = fn(obj[key], key);
return result;
}, {});
}
function pick(obj, fn) {

Promise protips - stuff I wish I had known when I started with Promises
// Promise.all is good for executing many promises at once
Promise.all([
promise1,
promise2

// Promise.resolve is good for wrapping synchronous code
Promise.resolve().then(function () {
if (somethingIsNotRight()) {
throw new Error("I will be rejected asynchronously!");
