Use A Specific Config File

When running webpack, the default config file that it looks for is webpack.config.js. If you have a project that uses different webpack config files for different environments, you will need to specify which config file webpack should use. The --config flag can be used with webpack to specify that file. For instance, if you want to use your production webpack config, run a command like the following:

$ webpack --config webpack.config.production.js
