preact X type error

See original GitHub issue

I’m getting undefined is not an object (evaluating 'h.__H') after building with rc3,

	o (bundle.269f6.js:1:8826)
	i (bundle.269f6.js:1:8957)
	O (bundle.269f6.js:1:8604)
	O (bundle.269f6.js:1:16581)
	w (bundle.269f6.js:1:16048)
	k (bundle.269f6.js:1:17676)
	_ (bundle.269f6.js:1:13235)
	u (bundle.269f6.js:1:19075)
	pwNi (bundle.269f6.js:1:19106)
	e (bundle.269f6.js:1:106)
	(anonymous function) (bundle.269f6.js:1:1351)
	Global Code (bundle.269f6.js:1:1364)

what am I overlooking?

When I look at the output of your bundle it’s pointing to different bundles of Preact (Preact seems to be bundled in multiple times)

Adding:

resolve: {
    // Add `.ts` and `.tsx` as a resolvable extension.
    extensions: [".ts", ".js"],
    alias: {
      preact: path.resolve(__dirname, 'node_modules', 'preact'),
      'preact/hooks': path.resolve(__dirname, 'node_modules', 'preact', 'hooks'),
    }
  },

To your webpack.config.js does not only reduce bundle size it also removes the error, note that a setup like this would fail with any framework.

@developit I checked an there definitely are no copies of Preact 8 in node_modules.

I’ve created a repo that reproduces the issue https://github.com/maltium/repro-preact-hook
