Preact Compat Versions Save

? Reminder: This module is for Preact 8.x and prior - Preact X includes compat by default. For Preact X, please uninstall preact-compat and replace your aliases with preact/compat.

• adds support for createContext(), courtesy of preact-context (#529, thanks @probablyup!)

Reminder: preact-compat should never be used with Preact X.

preact-compat should never be used with Preact X. Doing so will have unintended consequences including the pollution of Object.prototype (example).

This release of preact-compat changes peerDependencies to warn when installing alongside Preact 10+. You can (and should) continue to use preact-compat in conjunction with Preact 8 and prior.

If you're having trouble finding references to preact-compat in your codebase, try using a Webpack alias:

resolve: {
  alias: {
    'preact-compat': 'preact/compat'
  }
}
