point jsnext:main to src/index.js for rollup.js (WIP)

[robinplace]

This will let other packages do:

import { connect } from 'preact-redux'

See https://github.com/rollup/rollup/wiki/jsnext:main, and
https://github.com/developit/preact/blob/master/package.json#L7.

Ugh, hold off on this one... it's trickier than I thought with the way this package wraps react-redux...

[developit]

Indeed! We might be able to create a second dist file for jsnext main. It's a pretty optimized build already though, spent a whole day tweaking it last week :)

The problem I'm having is that rollup-plugin-commonjs doesn't understand the way the export is being done, so won't work:

import { connect } from `preact-redux`

So I'm having to put preact-redux in as a specifically named export in my rollup.config.js:

commonjs ({
    include: 'node_modules/**',
    namedExports: {
        'preact-redux': [ 'connect', 'Provider' ],
    },
}),

This is documented here in rollup-plugin-commonjs's README.

I just took a look at the source of rollup-plugin-commonjs and how it determines what can be imported from a CommonJS module and it looks like on line 165-ish its searching the file for this expression:

module.exports = { ... }

If I manually modify your dist/preact-redux.js to do it's exporting in that style, rollup works perfectly. It's kind of funny situation because rollup-plugin-commonjs's code analysis is just looking for the string "module.exports" and it doesn't care how or where if finds it.

So, is there an easy way to hack the build a tiny bit to make Rollup happy?

Or maybe we're better off dropping CommonJS entirely for rollup and creating a whole new build process to create an ES2015-style build? Maybe that way all the tree-shaking and magic can do it's stuff?

@robbiewxyz I have a solution, will post back in an hour or so! I should have used default exports in the rollup build :)

[developit]

@robbiewxyz The reason I've set up transpiling here is actually to prune a bunch of unnecessary stuff (proptypes, invariants, etc) out of react-redux. It's about 10kb normally, but preact-redux is 2kb.

I've copied the fix from another repo and released it as 1.2.0. Let me know if that worked! (sorry for the auto-close there)
