   It seems when you bundle your application a tool like e.g babel (babel-loader) adds a 'use strict'; pragma to the bundle file and depending on the browser (e.g without decent ES2015 (ES6) support) you're using this might leads to the current {Error} you're experiencing. Try to remove the pragma from the app.js file and check if this fixes your {Error}, then checkout how to disable that behavior. I'm closing this issue since it's likely unrelated to webpack-dev-server in particular, but feel free to reopen if more information is provided why this maybe related

   i have install webpack-dev-server to 2.11.3 and not use babel-loader strict mode so you think this is babel bring this problem?

   Either webpack or babel (babel-loader) add a 'use strict' pragma (I think it is babel). e.g

   file.js

   const a = 42

   file.transpiled.js

   'use strict'; // <= added by babel
   
   var a = 42;

   yet you exlude the node_modules folder and one of your dependencies might use ES6 Syntax which doesn't get transpiled atm eventually leading to e.g

   file.js

   import dep from 'pkg'
   
   const a = 42

   file.transpiled.js

   'use strict'; // <= added by babel
   
   // import dep from 'pkg' (not transpiled)
   const dep = true // <= {Error}
   
   var a = 42;
