Set environment variable in grunt that is accessed in webpack

Question

I am initiating webpack from a Gruntfile .

If I have a task like this:

grunt.registerTask('start', ['browser', 'webpack-dev-server'], () => {
  // how do I set an environment variable?
}); 

How can I set some part of env so that it is accessible in webpack?

If you're executing webpack in your arrow function, you can set the environment variable on process.env first:

grunt.registerTask('start', ['browser', 'webpack-dev-server'], () => {
    process.env.SOME_VARIABLE = // ... some value here
    // ... execute webpack
});
