Fract (Fake-React)

A hobby project that tries to recreate React from scratch.

Accent is made on maintaining compatability between the APIs while also adding additional strictness and removing legacy features.

Demo

NOTE:
This project is not intended for production use.
It is not tested and has no performance optimizations.

Features

Things Fract can do:

• Functional components
• First-class TypeScript support
• useState, useEffect, useCallback, useRef and useMemo hooks
• User-defined hooks (including nested hooks)
• Support for rules-of-hooks ESLint rules
• Chaining multiple state updates together
• Event listeners
• Strict mode (always ON)
  • Fract does not show warnings. It throws an exception immediately, making
    sure bugs get discovered quicker.
  • APIs don't have default values. All arguments must explicitly provided.

Things Fract can't do (yet):

• ReRendering
• Props
• Nested components
• JSX
• Context
• Portals
• Error boundaries
• Performance optimizations
• DevTools integration
• Run-time validation of intrinsic elements' attributes

Things Fract would never support:
