Creating a Gulp automation task to handle ng-constant across various environments

Question

Creating a Gulp automation task to handle ng-constant across various environments

I've been attempting to make this work, but it seems like I might be overlooking something. I'm utilizing ng-constant and configuring different environment endpoints as outlined in the ng-constants issue

However, my setup involves using gulp and the configuration appears like this:

gulp.task('environmentsapi', function () {
return ngConstant({
    stream: true,
    development: {
        constants: {
            "ENV": {"api": "http://1.1.1.1:8082/"}
        }
    },
    production: {
        constants: {
            "ENV": {"api": "https://productionapplink/"}
        }
    }
})
// Writes config.js to dist/ folder
.pipe(gulp.dest('dist/scripts/config'));
});

I am struggling to understand how to access the different endpoints in the various gulp tasks like the example in the link ngconstant:development etc. How can I execute this within the environmentsapi task, considering that this task is utilized in all environment builds? Please advise on how to accomplish this.

gulp.task('build', function () {
runSequence('clean', ['sass', 'scripts', 'bower_components', 'environmentsapi' //How can I run ngconstant:development here? ], 'wiredep')
});

To simplify the process, create new tasks to set flags!
Here, I am utilizing the development flag with a default setting of true.

var development = true;

gulp.task('prod', function () {
  development = false;
});

gulp.task('environmentsapi', function () {
    const apiEndpoint = development ? 'http://1.1.1.1:8082/' : 'https://productionapplink/';
    return ngConstant({
        stream: true,
        constants: {
            'ENV': {api: apiEndpoint}
        }
    });
});

By running gulp build, your application will be built with the ENV.api pointing to 'http://1.1.1.1:8082/', the development endpoint.

Executing gulp prod build will change the output to utilize an ENV.api set as 'https://productionapplink/'.

The solution above works well for two environments, but it can become complex with more. An alternative is to use yargs.

Below is an updated version of your gulpfile.js:

const argv = require('yargs').argv;

const endpoints = {
    'dev': 'http://1.1.1.1:8082/',
    'prod-org': 'https://productionapplink.org/',
    'prod-com': 'https://productionapplink.com/',
    'prod-gov': 'https://productionapplink.gov/'
};

gulp.task('enviornmentsapi', function () {
    const apiEnpdoint = typeof argv.env === 'undefined' ? endpoints.dev : endpoints[argv.env];
    return ngConstant({
        stream: true,
        constants: {
            ENV: { api: apiEnpdoint }
        }
    }).pipe(gulp.dest('dist/scripts/config'));
});

Usage:

gulp build uses the default api URL: 'http://1.1.1.1:8082/'
gulp build --env=prod-org uses 'https://productionapplink.org/'
gulp build --env=prod-com uses 'https://productionapplink.com/'

This flexible approach should help manage multiple environments effectively!
