Chunkhash in filename still differs about chunk-manifest-webpack-plugin HOT 9 OPEN

(This may totally be an issue in webpack itself, I just thought I would post an issue here as the likelihood someone looking at this repo has run into this problem is higher than webpack repo itself)

from chunk-manifest-webpack-plugin.

I just created this issue: webpack/webpack#1315. Has an example as well: https://github.com/kevinrenskers/chunkhash-problem.

from chunk-manifest-webpack-plugin.

Cool - glad to see I'm not alone.

I'll follow that thread and this one to see if anyone has relevant knowledge towards cause or a fix.

Is this still a pain point for others?

I found a solution that works for my use-case. I will raise a PR so @diurnalist and others can critique. But tomorrow after sleep.

from chunk-manifest-webpack-plugin.

So at startup WebpackOptionsApply adds a lot of default plugins. One of them is TemplatedPathPlugin, at WebpackOptionsApply.js#L266.

Noting that MainTemplate is the implementation of compilation.mainTemplate the MainTemplate.updateHashForChunk() routine will determine the hash of the entry chunk. It exposes a "hash-for-chunk" extensibility point which is hooked by TemplatedPathPlugin.

The problem is that TemplatedPathPlugin adds the hashes of other chunks into the digest. I believe this is on the presumption that the entry chunk will contain the chunk manifest. The hashing routine is not a pure function so simply adding another "hash-for-chunk" routine will not undo the effects of TemplatedPathPlugin.

I am proposing a monkey-patch of MainTemplate.updateHashForChunk() such that it does not call the "hash-for-chunk" extensibility point. This is working for my use-case (sorry closed source). I am interested whether this solves the problem for @alexhancock and @kevinrenskers.

You can install from bholloway/chunk-manifest-webpack-plugin and I have PR #9.

Additionally, let me know if this is relevant to webpack/webpack#1315.

from chunk-manifest-webpack-plugin.

This issue should be closed based on the response to the question I posed.

Essentially if you use webpack-md5-hash plugin the problem goes away.

Refer to webpack/webpack#1315 for a full solution.

Using the md5hash plugin still having an issue with naming of the chunks; PR #11
