Short description of the problem:

After updating to the newest release, I see that IONIC_ENV is not being set anymore.

What behavior are you expecting?

It should be set to either dev/prod depending on which mode the build is run in.

Steps to reproduce:
1.
2.
3.

I currently use it in a custom Rollup config file:

// For reference, check the following:
// https://github.com/driftyco/ionic-app-scripts/blob/master/config/rollup.config.js
// Config borrowed from: https://github.com/driftyco/ionic-cli/issues/1205#issuecomment-255744604
const nodeResolve = require('rollup-plugin-node-resolve');
const commonjs = require('rollup-plugin-commonjs');
const globals = require('rollup-plugin-node-globals');
const builtins = require('rollup-plugin-node-builtins');
const json = require('rollup-plugin-json');
// We will use the machine ip to make HTTP requests to the local machine from an external device while in dev mode.
const ip = require('ip');
// We use the replace plugin to provide the correct env variables
const replace = require('rollup-plugin-replace');

console.log(process.env.IONIC_ENV, process.env)


// https://github.com/rollup/rollup/wiki/JavaScript-API
const config = {
    /**
     * entry: The bundle's starting point. This file will
     * be included, along with the minimum necessary code
     * from its dependencies
     */
    entry: process.env.IONIC_APP_ENTRY_POINT,

    /**
     * sourceMap: If true, a separate sourcemap file will
     * be created.
     */
    sourceMap: process.env.IONIC_GENERATE_SOURCE_MAP ? true : false,

    /**
     * format: The format of the generated bundle
     */
    format: 'iife',

    /**
     * dest: the output filename for the bundle in the buildDir
     */
    dest: process.env.IONIC_OUTPUT_JS_FILE_NAME,

    /**
     * plugins: Array of plugin objects, or a single plugin object.
     * See https://github.com/rollup/rollup/wiki/Plugins for more info.
     */
    plugins: [
        builtins(),
        commonjs(),
        nodeResolve({
            module: true,
            jsnext: true,
            main: true,
            browser: true,
            extensions: ['.js']
        }),
        globals(),
        json(),
        replace({
            values: {
                '{{API_HOST}}': process.env.IONIC_ENV === 'prod' ? 'https://test-api.herokuapp.com' : `http://${ip.address()}:8888`
            },
            // Config
            exclude: 'node_modules/**'
        })
    ]

};

module.exports = config;

Which @ionic/app-scripts version are you using?
0.0.47

As a workaround I use:

// NOTE: If IONIC_ENV is not set, we check if the CLI args contain the '--prod' flag.
function isProd() {
    return process.env.IONIC_ENV === 'prod' || process.argv.slice(2)
            .some((arg) => arg.indexOf('--prod') !== -1)
}

It works fine, though ideally IONIC_ENV should suffice.

Can confirm. IONIC_ENV is not set for me as well.
Please forgive my rant.. but app-scripts are the worst, really the worst part of ionic and we as a development team suffer big time because of them over and over again.

[ekrapfl]

I can also confirm that IONIC_ENV is not set. This is kind of a big deal, is anyone tracking this at Ionic?

[danbucholtz]

This is in master, I'll close tomorrow when we publish 0.0.48.

Thanks,
Dan

[cmaart]

Thank you very much for your fast response time!

[danbucholtz]

It was an internal miscommunication. We were going to deprecate it (we did, in fact :)) but we decided now to keep it after all.

Thanks,
Dan

[danbucholtz]

This will land in 0.0.48 today.

Thanks,
Dan

[danbucholtz]

Hi all,

This is resolved in 0.0.48 which was just published.

Please let me know if you have any issues.

Thanks,
Dan

[rolandjitsu]

This one works as well 👍

[riteshwaghela]

I am using 0.0.48, but still it is not working. I am using this command ionic build --prod but the env is still dev. Even the temporary solution mentioned by @rolandjitsu (isProd()) is not working because process.argv does not list the --prod argument. Any help? Thanks

[danbucholtz]

You should really update. 0.0.48 is old. 1.1.1 is the latest.

Thanks,
Dan

I am using 1.1.4 and it is not working. For example I use "ionic-app-scripts build --prod" but the IONIC_ENV is undefined. Tried setting the source directory and it is also undefined.

For me this feature seems to be broken.

https://github.com/driftyco/ionic-app-scripts/blob/master/src/util/config.spec.ts#L166

It should be set correctly. Our tests around that pass. How are you trying to use it?

Thanks,
Dan

[TheHighriser]

Thanks for the quick response. So maybe I am wrong. Can I use the ENV in Hooks? Because I am setting the src_dir in the package.json like this:

"config": {
    "ionic_src_dir": "./hello"
}

And it doesn't work. When I call process.env in the hook code it won't show me any Ionic Environment Variables.
