Why isn't this 1.5.0 like the one is web-config?

The latest types available are 1.4.2. 1.5.0 does not have types available.

@elevatebart we did, but then I realized this won't work for webpack 5 users. So we need to support a range of html-webpack-plugin that corresponds to the range of webpack version we support (4.x and 5.x). |

Remove
html-webpack-plugin@4as a direct dependency for@cypress/webpack-dev-server.Additional details
Making
html-webpack-pluginapeerDependency, and allows versions 4 and 5. This means the user must install eitherhtml-webpack-plugin@4andwebpack@4orhtml-webpack-plugin@5andwebpack@5.I also removed some types that conflicted between webpack 4 and 5.
I added a nextjs webpack 5 example but cannot get it to run on CI. I tested manually. We have to specify a set version for
webpackandhtml-plugin-webpackin@cypress/webpack-dev-serverunderdevDependencies. What would be ideal is some way to conditionally change this depending on the which example project is running, but I couldn't find a good solution. I even triedcp examples/nextjs-webpack-5/node_modules/{webpack,html-plugin-webpack} ../../../webpack-dev-server/node_modules, but this messed things up royally on CI and is a hack.I think ideally the examples projects should somehow install
@cypress/webpack-dev-serverinto their ownnode_modulesdirectory instead of relying on traversing up to the local version. This would solve a lot of problems and make the test more "real world".For now I just left the nextjs example there with the goal of finding a good way to run it on CI in the future.
Nextjs specifically introduces complexity because they inline their webpack version - it's not installed in
node_modules, but compied and shipped as part of theirnext/serverpackage.How has the user experience changed?
You can bring your own webpack and html-webpack-plugin version. Must be 4 or 5.
Perhaps we can update the Cypress wizard in the future to account for
next.config.js, wherewebpack5: truecan be configured.PR Tasks
