'Provider' is not exported

[sydev]

I ran in an issue where following error is thrown:

Error: 'Provider' is not exported by node_modules/preact-redux/dist/preact-redux.js
    at error (/Users/dominik/code/material-explorer/node_modules/rollup/dist/rollup.js:170:12)

My implementation:

import preact from 'preact';
import {Provider} from 'preact-redux';
import {createStore} from 'redux';

// Components
import App from './components/app.jsx';

const store = createStore();

preact.render(
  <Provider store={store}>
    <App />
  </Provider>, 
  document.getElementById('app'));

Can someone confirm this error?

@sydev what bundler are you using?

[sydev]

I use rollup with gulp. Here my config:

// Build JS
  gulp.task('build-js', () => {
    let env = process.env.NODE_ENV;

    return rollup({
      entry: './src/js/main.jsx',
      plugins: [
        resolve(), 
        replace({'process.env.NODE_ENV': JSON.stringify(env)}),
        common(),
        babel({exclude: 'node_modules/**'}),
        env === 'productions' && uglify()
      ],
      format: 'iife'
    }).pipe(source('main.jsx', './src/js/'))
      .pipe(buffer())
      .pipe(rename({extname: '.js'}))
      .pipe(gulp.dest('./client/assets/js'));
  });

@sydev I think you need to do resolve({ jsnext: true }) (I'm assuming resolve is rollup-plugin-node-resolve)

[sydev]

@developit Yeah, resolve is rollup-plugin-node-resolve. But adding {jsnext: true} does not change anything but the referenced file in thrown error:

I also tried {jsnext: true, module: true}, {jsnext: true, main: true} and {jsnext: true, main: true, module: true}.

Now it´s preact-redux.esm.js, not preact-redux.js, which seems right to me, because preact-redux.esm.js IS exporting Provider:

Strange error :(

[developit]

Ah - it's the same thing I fixed last week in preact-compat: https://github.com/developit/preact-compat/commit/a4624cdef9af217c146f28ce5ce6fe084abed775

[lohfu]

Is this being fixed? Looking through the package.json i see jsnext:main points at dist/preact-redux.esm.js... which does not export any named exports at all, only a default export

[lohfu]

@developit are there any plans on exporting named exports from dist/preact-redux.esm.js?

[developit]

Yes - I need to merge Ezekiel's PR.

[developit]

Fixed in 2.0.2
