How to set multiple env variables using cross-env?

问题

Does anyone know how to set multiple env vars using cross-env ? I was trying running the following script without success.

"cross-env NODE_ENV=production DTM_ENV=staging webpack --config internals/webpack.prod.babel.js --color -p --progress"

On console.log(process.env) it only displays NODE_ENV: "production".

回答1:

Webpack doesn't have access to env variables after the build is done, so you need to expose those variables by adding this into Webpack config into plugins:

new webpack.DefinePlugin({
  'process.env': {
    NODE_ENV: JSON.stringify(process.env.NODE_ENV),
    DTM_ENV: JSON.stringify(process.env.DTM_ENV),
  }
})
