All React.js introductions seem to suggest that React uses a server to create virtual DOMs and sends diff operations over to client, but I just tried out the flux-todomvc which it didn't need a server at all. What's going on? Is the "server side" work done inside web worker thread?
You don't necessarily need a static server in order to run a Create React App project in production. It also works well when integrated into an existing server side app.
Yes! This is where server-side rendering for React comes in. In this article, I want to introduce you to server-side rending (SSR) with React, reasons to use it, and some popular frameworks for rendering React on the server side.
js or Gatsby, you don't need a backend. Instead, you could simply write your blog posts as markdown files, which are stored and tracked (using Git) within a project folder.
Think of ReactJS as a server-side templating engine here (like jade, handlebars, etc...). The HTML rendered by the server contains the UI as it should be and you do not wait for any scripts to load. Your page can be indexed by a search engine (if one does not execute any javascript).
React.js does not use a web server to create virtual DOMs. It builds the virtual DOM and does its diff operations on the client's browser.
But you can use Node.js to render them on the server side if you like (for seo purposes etc.)
