What is difference between React and Preact?

What is difference between React and Preact?

There are many differences between React and Preact that we can summarize in three points: Features and API: Preact includes only a subset of the React API, and not all available features in React. Size: Preact is much smaller than React. Performance: Preact is faster than React.

How much faster is Preact?

Preact initially renders the UI 3-4x faster than React. Vanilla JS initially renders the UI anywhere from 5-10x faster than Preact, and about 30x faster than React! Handling UI state changes with vanilla JS is also orders of magnitude faster than using Preact or React.

Should we use Preact?

A big advantage of switching to Preact from React is that you’ll make your bundle-size smaller, and your app will load faster – this can be a key requirement for some projects. But on the other hand, while choosing Preact you can lose some React features.

Is Preact based on React?

As mentioned above, Preact is a 3kb alternative to React developed by Jason Miller and a bunch of contributors. Preact was developed with the goal of building a JavaScript framework that’s small in size and yet offered the same API and features that React ships with.

Why do people React to Preact?

Preact is a lot faster and lighter than React. And it aims to be “mostly” compatible with React. To have near 100% compatibility Preact offers an additional package: preact-compat . Preact is compatible and even encourages using htm over JSX so you can unlock regular HTML attributes.

Why use Preact instead of React?

The reason Preact does not attempt to include every single feature of React is in order to remain small and focused – otherwise it would make more sense to simply submit optimizations to the React project, which is already a very complex and well-architected codebase.

Why is Preact so much smaller than React?

What’s the difference between PreAct and react compat?

Preact itself is not intended to be a reimplementation of React. There are differences. Many of these differences are trivial, or can be completely removed by using preact-compat, which is a thin layer over Preact that attempts to achieve 100% compatibility with React.

What’s the difference between PreAct and JSX?

Preact uses native addEventListener so it trusts/uses the DOMs API to a performance and size benefit. Preact doesn’t push JSX as it’s client-side templating tool. In fact, the original author of Preact offers his package htm as an alternative.

How are new features added to PreAct core?

When new features are announced by the React team, they may be added to Preact’s core if it makes sense given the Project Goals. This is a fairly democratic process, constantly evolving through discussion and decisions made in the open, using issues and pull requests.

Why are there so many issues with PreAct?

The reason for this is that anything related to HTML ends up requiring that folks use (more) specific server-side techniques, versus the current simplified renderToString () approach. I’ll try to prioritize at least publishing some of the exploratory work and demos we have.
