How to set React to production mode when using Gulp

Question

I need to run React in production mode, which presumably entails defining the following somewhere in the enviornment:

process.env.NODE_ENV = \'production\';
         


        

Answer 1

Also you may use handy way with gulp-environments:

var environments = require('gulp-environments');

var production = environments.production;

gulp.src(paths.js)
    .pipe(concat("app.js"))
    // only minify the compiled JS in production mode
    .pipe(production(uglify()))
    .pipe(gulp.dest("./public/app/js/"));

To run gulp in production mode:

gulp build --env=production
