Make filesize analysis match browserify bundling

[Raynos]

It would be nice if the total size matches what browserify bundles too. Currently one of my files is 184kb vs 198kb where browserify produces an extra 14kb

browserify will add extra code to the bundle for the basic require emulation.

It will also add extra kb of padding around every module with it's function (require, module, exports) wrapping.

It also detects global usage of process and adds the process emulation to the bundle as well.

@Raynos process and Buffer now get picked up and included (the latter is ~100kB so pretty significant), along with the require emulation.

Not sure how to handle the padding precisely though, if I understand correctly that can vary depending on the options passed to browserify - maybe that's better not included, given you still get results that reflect the proportions of the bundle being taken up by specific files?

Edit: would be interesting to know how much unaccounted space is left in your bundle now :)

I prefer not accounting for the padding. Including the Buffer in file size makes it even more important to have a nodejs option.

@ForbesLindesay Yup - that's coming up next :)

cool :)

👍

I have a case where the total size shown is 303kb, whereas the same file after bundling is 198kb.
