WIP - Use Pundle as the module bundler

[steelbrain]

⚠️ This PR is in no way feature complete and is just meant to start the discussion ⚠️

Reference: #93 (comment)

This PR uses the Pundle module bundler instead of Webpack

What's working?

• Hot reloads
• Everything JS + JSON

What needs some work?

• Non JS requires
• ESLint

I will be implementing the missing plugins for Pundle as we make progress on this PR

What's the benefit?

Well documented and maintained software that has extremely fast bundling and hot reload speed compared to Webpack

It looks like the other requirements here are fixed versions instead of ^, probably it's better to do the same for pundle

[steelbrain]

Done

Does pundle support any sort of built-in proxying behavior? We need something like that to support backend servers.

If we used pundle instead of webpack, do you think pundle should also be used to package files for the test environment? Or is that not a good fit for pundle?

[lacker]

can this be process.env.PORT || 3000 ?

You would want to change build.js too I presume, so that we would no longer have any webpack dependencies.

[steelbrain]

Pundle supports fully configurable bundle paths (including their source map and hmr paths) so it's very easy to use it behind a proxy. In fact we're already using it in our dev environment.

Also Pundle has two main external components, The Dev Server and the main CLI, it can compile anything and probably more than what webpack is capable of :)

Also I'm working on transitioning build.js too right now, as the title says it's still a WIP but reviews are very much welcome on the stuff committed in

Would love to see production build sizes and benchmarks on the page speed.

[gaearon]

This doesn’t currently handle styles, does it?

[steelbrain]

This is build time in Pundle vs Webpack (respectively)

That's like a 2.3x boost. Pundle is especially fast at HMR, it's HMRs are near-instant.

@gaearon Yeah it's being actively worked on, as the ETA it's happening soon :)
@TheLarkInn Pundle's build sizes are slightly bigger than webpack's at the moment but the runtime performance is probably faster. Sizes are gonna be fixed soon.
It's mainly because webpack has been tweaked heavily to minificiation and all

Closing as outdated, but feel free to reopen when there is a reasonable feature parity!

I wonder if there is any update on this. ?
