Cannot read property 'tapAsync' of undefined when using with HTML Webpack Plugin 4.0.0-alpha.2

[ajaybc]

Description

I used the latest create-react-app CLI to bootstrap my project and then I ejected it. The latest create-react-app uses "html-webpack-plugin" version 4.0.0-alpha.2. When I use "csp-html-webpack-plugin" with it I am getting the following error

Cannot read property 'tapAsync' of undefined

I have already tried placing "csp-html-webpack-plugin" at the end of the plugins list after "html-webpack-plugin" and still I am getting the same issue.

Thanks for reporting!

We have PR #16 in flight which will include webpack 4 support and fix this error :)

@AnujRNair Thanks for the reply. Can we have a beta version of the "csp-html-webpack-plugin" with the support. Pretty please :)

@ajaybc html-webpack-plugin final version will be available by the end of this month. and @AnujRNair
clearly stated here #16 (comment)

but won't actually merge until HTMLWebpackPlugin comes out of alpha and beta, just incase there are unforseen API updates

he is waiting for the final release. So you may have to wait 10 more days.

Also @AnujRNair. I am pretty sure, that there will be no api changes to the plugin. based on jantimon/html-webpack-plugin#953 (comment)

HtmlWebpackPlugin 4 functionality has been merged!
