webpack-dev-server not build file

Created on 3 Feb 2018 · 2Comments · Source: webpack/webpack-dev-server

webpack.config.js:

  devServer:{
    inline: true,
    contentBase:'./',
    port:3000
  },

after I change about.js in my project. It outputs:

webpack: Compiling...
Hash: ba77a3145fee91718778
Version: webpack 3.10.0
Time: 28ms
          Asset       Size  Chunks             Chunk Names
about.bundle.js  444 bytes       1  [emitted]  about
 + 2 hidden assets
  [23] (webpack)/hot nonrecursive ^\.\/log$ 170 bytes {2} [built]
  [27] ./dist/about.js 188 bytes {1} [built]
    + 34 hidden modules
webpack: Compiled successfully.

after I changed the code. The calculation of the size of "about.bundle.js" in the log seems right. But the file "about.bundle.js" not changed. So the page not refresh and reload.

How could I debug this bug?
