How to resolve - Error: [HMR] Hot Module Replacement is disabled

iroy2000 commented 7 years ago

I'm trying to follow the instruction here

webpack.config.server.dev.babel.js ''' entry: [ 'webpack/hot/signal.js', SERVER_ENTRY_POINT ],

// ...

plugins: [ new webpack.HotModuleReplacementPlugin() ] '''

And I run this command

webpack --config webpack.config.server.dev.babel.js --watch

And seems like it is working

However, when I run this command

nodemon my-build/index.js -- watch

I got the following error ...

/node_modules/webpack/hot/signal.js:64
        throw new Error("[HMR] Hot Module Replacement is disabled.");
        ^
Error: [HMR] Hot Module Replacement is disabled.

How can I resolve that issue? Thanks for any help.

How was this resolved? I'm having the same problem

Hey, wanted to note for anyone else stumbling across this due to a search, the reason it wasn't working for me is because on the server I had node_modules marked as externals, e.g:

  nodeExternals({
    whitelist: /(?:@mylib)/,
  }),

but what I needed to do was also whitelist the HMR entrypoint:

  nodeExternals({
    whitelist: /(?:@mylib|webpack\/hot\/signal)/,
  }),

Hope that helps the next poor soul! :heart:
