javascript - Environment variables not passed in Gulp/Node -


so have gulp task sets node_env, , run set env variable before run dependant tasks.

//gulpfile.js  gulp.task('set-dev-environment', () => {     return process.env.node_env = 'development'; });  gulp.task('compile-dev', ['set-dev-environment'], () => {     console.log(process.env.node_env); // (1) correctly prints "development"      const config = require('./configuration.js');     //...do config... })

here configuration.js

// configuration.js  console.log(process.env.node_env); // (2) prints undefined!! const __dev__ = process.env.node_env === 'development' if (__dev__) {     // return development configuration } else {     // return production configuration }

as can see, after set environment variabale, "require" configuration.js file, returns different content based on environment variable.

this extremely simplified version of code, point when "require" js file, node_env undefined.

however in gulp task 'compile-dev', turns out node_env set correctly.

from logs, seems if (2) printed before (1), meaning configuration.js required before 'compile-dev' run in gulp..

why isn't configuration.js imported dynamically (after env variable set), , how fix problem?
