Why Use Preact?

Preact is a lightweight model of React. You may choose Preact as a lightweight alternative if you like building views with React yet performance, speed and size are a need for you – for instance, in case of mobile web applications or progressive web applications.

Regardless of whether you’re starting a new project or building up a current one, Preact can save you a ton of time. You don’t have to waste time attempting to become familiar with another library, since it’s similar and compatible with React – to the point that you can use existing React packages with it with just some aliasing, on account of the similarity layer preact-compat.

For some time, React has been one of the most preferred tools for front-end developers. Sometimes, it can be a little heavy. However, A lighter option known as Preact is generally compatible with React.

We’ll Go Over The Differences Now

  • Closer to the DOM:

Preact gives the thinnest conceivable Virtual DOM extraction on top of the DOM. It enlarges on stable platform features, register real event handlers and plays pleasantly with different libraries.

Preact can be utilized straightforwardly in the program with no transpilation steps.

  • Small Size:

Most UI frameworks are large enough to be most of an application’s JavaScript size. Preact is extraordinary: it’s small enough that your code is the biggest piece of your application.

That implies less JavaScript to download, parse and execute – allowing for your code, so you can build an experience you characterize without fighting to monitor a framework.

  • Compact and Embeddable:

Preact’s small impression implies you can take the amazing Virtual DOM Component prototype to new places it couldn’t otherwise go.

Use Preact to build portions of an application without complex integration. Insert Preact into a widget and apply the same tools and procedures that you would build a full application.

  • Big Performance:

Preact is quick, and not because it’s light in size. It’s one of the fastest Virtual DOM libraries out there, thanks to a simple and predictable diff execution.

You can automatically batch updates and tune Preact to the maximal when it comes to performance. JavaScript development company in India closely work with developers to get the maximum performance possible out of Preact.

  • Instantly Productive:

    Lightweight is much more fun when you don’t need to give up productivity to get there. Preact gets you productive immediately. It even has a couple of extra features:

    • props, state and setting are passed to render ()
    • Use standard HTML attributes like class and for
  • Ecosystem Compatible:

Virtual DOM Components make it simple to share reusable things – everything from buttons to data providers. Preact’s design implies you can flawlessly use a large number of Components accessible in the React ecosystem.

Adding a simple preact/compat alias to your bundler gives a compatibility layer that empowers even the most complex React components to be used in your application.

  • Declarative:

React makes it effortless to create interactive UIs. Design simple perspectives for each state in your application, and React will effectively update and deliver the perfect components when your data changes.

Declarative views make your code more predictable and simpler to troubleshoot.

  • Component Based:

Build compress components that deal with their own state, at that point create them to make complex UIs.

Since component logic is written in JavaScript instead of templates, you can undoubtedly pass rich data through your application and keep the state out of the DOM.

  • Learn Once, Write Anywhere:

Don’t make presumptions about the rest of your innovation stack, so you can develop new features in React without rewriting existing code.

React can likewise deliver on the server using Node and power mobile applications using React Native.

  • A Simple Component:

React components execute a render () technique that takes input data and returns what to display. This model uses an XML-like syntax called JSX. Data that is passed into the component can be accessed to by render () through this.props.

JSX is optional and not needed to use React. Try the Babel REPL to see the raw JavaScript code created by the JSX compilation step.

  • A Stateful Component:

In addition to taking data(access via this.props), a component can keep up internal state data (access via this.state). However, when a component’s state data changes, the delivered markup will be updated by re-invoking render ().

  • An Application:

Utilizing props and state, you can put together a small Todo application. This model uses state to follow the current list of things just as the content that the user has entered. In spite of the fact that event handlers give off an impression of being delivered inline, they will be collected and implemented using event delegation.

  • A Component Using External Plugins:

React allows you to interface with different libraries and frameworks. This example uses expectational, an external Markdown library, to change over the <textarea>’s value in real-time.

So Preact or React?

The answer to this question Preact or React really relies upon your use case. A tradeoff to switching over to Preact from React is that you’ll in all probability need to get rid of certain features, or if nothing else need some setup to use a portion of the features that ships with React (preact-compat).
