Building an app with @reactjs? Accept payments with our new React components that help you quickly add @stripe! ⚛️🚀✨

  • React components that help you quickly add Stripe Elements to your React app.
  • Then, load Stripe.js in your application:

    In order for your application to have access to the Stripe object, let’s add to our root React App component:

    Next, when you’re building components for your checkout form, you’ll want to wrap the component around your .

  • All applications using must use the component, which sets up the Stripe context for a component tree.
  • uses the provider pattern (which is also adopted by tools like and ) to scope a Stripe context to a tree of components.
  • Components that need to initiate Source or Token creations (e.g. a checkout form component) can access via props of any component returned by the HOC factory.

Create React App with an Express Backend

Create React App with an Express Backend  #reactjs #expressjs #javascript

  • In this post we’ll set up a React app alongside an Express backend app, and wire up the UI to fetch some data from the backend.
  • Note the variable: this Express app will default to port 3000, and Create React App will also default to port 3000.
  • First things first, make sure you have installed if you don’t already:

    Then, from inside the folder, create the React app:

    This is the key change that will let the React app talk to the Express backend (or any backend).

  • Inside the React app’s folder ( ), open up (make sure it’s not Express’ package.json – it should have things like “react” and “react-scripts” in it).
  • At this point 2 servers are running: Express (on port 3001) and Create React App’s Webpack dev server (on port 3000).

Learn how to forward API requests from Create React App to any backend with the proxy setting.

Facebook Announces More Performant Version of React Framework

Facebook Announces More Performant Version of #React Framework 

 #ReactJS

  • At F8 —Facebook’s annual developer conference — the company’s engineers took to the breakout stages to discuss the newest versions of the React and Relay frameworks, both of which were rewritten from the ground up to deliver significantly better performance to the applications that are written with them.
  • In some cases, that means better performance for certain features of certain applications since developers can selectively apply the framework capabilities to some parts of their apps, and not others.
  • Occhino gave examples such as jank — a well-known term to developers that describes the jittery look of applications during user initiated operations such as page scrolling where, as opposed to a naturally fluid feeling, a page seems to stutter as it’s scrolled.
  • Another example Occhino discussed is when the user attempts to do something with their application and they get a pinwheel or some other indication that the system is busy with other tasks.
  • According to Occhino, given this set of circumstances, one way to naturally improve the perceived performance of a React app is to reprioritize tasks in a way that the experience that’s right in front of the end-user gets the highest priority in terms of system resources like CPU.

At F8 — Facebook’s annual developer conference — the company’s engineers announced a new version of React with a core designed to optimize the performance of applications that are written with the framework. The new core, React Fiber, is better at scheduling tasks based on what the user is doing.
