Webpack 4 compatibility

[vraptor75011]

When using webpack4, I get the following error. I think it s due to webpack3 dependency mixing with webpack4 new plugin system.

TypeError: Cannot read property 'additionalPass' of undefined at HotModuleReplacementPlugin.apply (/Users/vraptor/WebDev/test/node_modules/webpack/lib/HotModuleReplacementPlugin.js:32:18) at Compiler.apply (/Users/vraptor/WebDev/test/node_modules/hapi-webpack-plugin/node_modules/tapable/lib/Tapable.js:375:16) at new webpack (/Users/vraptor/WebDev/test/node_modules/hapi-webpack-plugin/node_modules/webpack/lib/webpack.js:33:19) at Object.register (/Users/vraptor/WebDev/test/node_modules/hapi-webpack-plugin/lib/index.js:44:16)

Any idea ? Thanks

@vraptor75011 I found I didn't install webpack-dev-server.You can check to see if you have installed it.

#20 have the same problem. I pushed my vue project on GitHub but I got a warning that I need to update webpack-dev server due to cross origin issues. When I did so, npm run dev shows the error below

It sucks that upgrading webpack-dev-server causes npm not to run, yet GitHub issues a security alert for using webpack-dev-server version lower than 3.1.14

It sucks that upgrading webpack-dev-server causes npm not to run, yet GitHub issues a security alert for using webpack-dev-server version lower than 3.1.14 #20 I got it to work by following this steps

1. Initialize your vue project. For now I will use vue-cli v2 vue init template-name project-name 1.1 npm install npm install
2. Install webpack 4.0.0 dependency. It is needed npm install webpack@^4.0.0
3. Install webpack version 3.1.11 or 3.1.14 or whichever one you want 'npm install --save-dev [email protected]'
4. Install vue loader 14.2.2 This is because it requires a vue loader and the latest one still has bugs npm add [email protected] I hope this helps somebody

Can confirm this issue still exists

It seems this package is unmaintained so I decided to rewrite it in TS and fix all the issues. You can find it here https://github.com/Kamahl19/hapi-webpack-plugin-2

Any plans to support Webpack 4.x @SimonDegraeve ?

I updated hapi-webpack-plugin in https://github.com/SimonDegraeve/hapi-webpack-plugin/issues/22 to support Webpack 4.x. There is a PR attached. Feel free to check it out.
