React and Grunt - Envify NODE_ENV='production' and UglifyJS

Question

I am using Grunt to build a React project and I want to have \'dev\' and \'prod\' flavours. As react docs says:

To use React in productio

Answer 1

Both John Reilly's and FakeRainBrigand 's answers did not work for me. What worked for me was the following:

Step 1 - Run this command where your package.json is

npm i grunt-env --save-dev

Step 2 - Add the code in "evn:" to your Gruntfile.js within grunt.initConfig like so:

grunt.initConfig({

...

env: {
    prod: {
        NODE_ENV: 'production'
    }
},

...

});

Step 3 - Add the grunt task to your Gruntfile.js

grunt.loadNpmTasks('grunt-env');

Step 4 - Call it before browserify like so:

grunt.registerTask("default", ["env", "browserify"]);
