process.env.NODE_ENV is undefined, caused 'isDevMode' useless

[linker-junhao]

hi, @mubaidr , thanks for your work, I am using it for days, it works fine.
and I found that process.env.NODE_ENV is undefined when I use npm run [] command, and I solved it. maybe you can fix it if it happend at your enviroment too.

hree is my enviroment:

npm -v
6.13.4
node -v
v13.6.0
webpack -v
4.41.6

I dont sure is here anybody else encounter this.
solution: according to webpack.js.org/api/cli/#environment-options, export your webpack config as a function will solve it.

like this:

function exportCfgFunction (env, argv) {
  const isDevMode = env.NODE_ENV === 'development'
  const config = {
    devtool: isDevMode ? 'eval-source-map' : false,
    context: path.resolve(__dirname, './src'),
    entry: {
    },
    output: {
    }
  }
  return config
}
module.exports = exportCfgFunction
