Webpack 5 "BREAKING CHANGE" warning #1501

GaryB432 · 2020-08-28T20:36:39Z

Expected behaviour

The excellent plugin should work with webpack 5 without deprecation notices

Current behaviour

Can you please check if 4.4.0 works for you?

AviVahl · 2020-08-30T16:58:45Z

@jantimon I've tested 4.4.1 (with [email protected] and [email protected]), and most deprecation warnings are gone. There's one left:

node:22153) [DEP_WEBPACK_COMPILATION_ASSETS] DeprecationWarning: Compilation.assets will be frozen in future, all modifications are deprecated.
BREAKING CHANGE: No more changes should happen to Compilation.assets after sealing the Compilation.
        Do changes to assets earlier, e. g. in Compilation.hooks.processAssets.

    at processTicksAndRejections (internal/process/task_queues.js:93:5)

I ran webpack-cli directly with --trace-deprecation, so you can see it's being logged at line 278:

compilation.assets[finalOutputName] = {
              source: () => html,
              size: () => html.length
            };

jantimon · 2020-08-31T08:15:50Z

Changing the hook would be a breaking change I guess - I'll ask the webpack core team on guidance which stage to use:

https://webpack.js.org/api/compilation-hooks/#processassets

I am not sure if this might cause issues with chunk hashes (as they are not known at this time)

nickbouton · 2020-09-01T04:18:34Z

@jantimon FYI, having the same issue exactly with 4.4.1 + [email protected].

rockwalrus · 2020-09-11T22:39:14Z

Here's some guidance that looks applicable: webpack/webpack#11425

tianyingchun · 2020-09-12T08:06:15Z

what's progress of this issue?

tianyingchun · 2020-09-12T08:08:11Z

having the same issue exactly with 4.4.1 + [email protected]

jungleBadger · 2020-09-12T21:25:16Z

Same issue with v4.4.1 and [email protected]

zanfirandra · 2020-09-15T07:23:59Z

In the meantime, for me using v.4.4.1 and webpack v5.0.0-beta.24 is the right combo. yes build is compiling with warnings but it doesn't get stuck at BREAKING CHANGE warning

tianyingchun · 2020-10-11T01:44:42Z

what progress about the compatibility of webpack@5, webpack@5 have been released 2020-10-10
There are lots of plugins based on html-webpack-plugin. 👍

0rvar · 2020-10-13T09:04:35Z

webpack 5.0.0, html-webpack-plugin 4.5.0:

Can you please see if this is fixed with [email protected] ?
Please see also #1527

I'm still seeing it after updating to 5.0.0-alpha.2

yeah, it still has this issue event if update to 5.0.0-alpha.2

jantimon · 2020-10-16T09:25:59Z

Sorry I missed some parts in the last release can you please try once again with [email protected]

Looks like that fixes it @jantimon 👍

I also have the same problem, provide reference.

Then updated with "npm i -D [email protected]"

Doubt：
The problem is resolved, but the HTML-Webpack-plugin: ^5.4.0 will the same be true for the version after .

jantimon · 2020-10-30T08:58:40Z

There is no version 5.4.0 by now.. But you are right we won't fix it for the 4.x branch

rnnyrk · 2020-12-15T10:12:13Z

Any updates on this fix/release going stable?

jantimon · 2020-12-15T11:07:04Z

@rnnyrk the tests are green again and there is only one last topic in #1527 to be solved - after that I expect no further breaking changes and would release a beta version..

if there won't be any bugs reported with that release I'll release it as a stable version

I hope that's fine

* Minifier WA can be now dropped since the pulled cssnano version includes the fix * Adjust to new copy-webpack-plugin API. * Adjust included node modules plugin needs to webpack 5 API * Update html-webpack-plugin to remove deprecation warnings Previously we would get: BREAKING CHANGE: No more changes should happen to Compilation.assets after sealing the Compilation. See jantimon/html-webpack-plugin#1501 * Use lite cssnano preset because the default version makes problematic assumptions Note: webpack's compilation.fileDependencies has changed and the webpack-make needs to be adjusted accordingly: webpack/webpack#11971

This is still happening with webpack 5.73.0 and html-webpack-plugin 5.5.0
