阅读更多关于 react-engine vs other template engines

问题 I was wondering to use paypal's React Engine (https://github.com/paypal/react-engine), but I have some doubts: What are the benefits over other template engines like Handlebars? Why upload .jsx files, and not (jsx precompiled/transformed) .js files? (This one should be faster because don't have to do deal with the transformation at the server). I have been researching but I get confused. Thanks 回答1: The main difference between react-engine and template engines is only when the browser enables

Facebook React.js: how do you render stateful components on the server?

阅读更多关于 Facebook React.js: how do you render stateful components on the server?

I think I'm conceptually missing something with server-side rendering using React.js Assume I want to create a page to display items from a server-side DB, with an input field to filter them. I want a page: that responds to a URL like /items?name=foobar with a React input field to filter the items by name with a React component to display the list of filtered items Assume I have a public REST API to query the items on the client side. Conceptually, what I want to do at first request ( GET /items?name=foobar ) is : I want my input field to show what the user passed as a Parameter, so I need to

I have a requirement in which I am rendering view in which I display a form. On submit of form i need to gather the form data and create a file and save form data as JSON in that file. I am using React.js, node.js, babel and webpack. After struggling a bit to achieve this I figured out that I have to use isomorphic or universal javascript i.e use react and render on server side as we cannot use fs module on client side. Referred this for server side . i run it using: npm run start After this I can see in console that [Object Object] is printed on console from Line 1 in below react component

I'm building a CMS system for managing marketing landing pages. On the "Edit Landing Page" view, I want to be able to load the associated stylesheet for whichever landing page the user is editing. How could I do something like this with React? My app is fully React, isomorphic, running on Koa . My basic component heirarchy for the page in question looks something like this: App.jsx (has `<head>` tag) └── Layout.jsx (dictates page structure, sidebars, etc.) └── EditLandingPage.jsx (shows the landing page in edit mode) Data for the landing page (including the path of the stylesheet to load) is

I'm trying to get an isomorphic Node.js, Express, Webpack, React app working. I'm getting the following error. Any suggestions on how to fix it? Warning: React attempted to reuse markup in a container but the checksum was invalid. This generally means that you are using server rendering and the markup generated on the server was not what the client was expecting. React injected new markup to compensate which works but you have lost many of the benefits of server rendering. Instead, figure out why the markup being generated is different on the client or server: (client) rgin:0;display:flex;
