How to setup environment files for dev, local and prod api urls, flag in NativeScript Vue? - vue.js

Question

The agenda is to use certain flags and a specific api base url for different modes say dev, local and prod in my NativeScript Vue app.
Just like NativeScript angular has environment.[mode].ts files?
I've tried using .env.[mode] files, by referring to VueJs docs
// https://cli.vuejs.org/guide/mode-and-env.html#environment-variables.com
But this did not favour the scenario.
// Something like this of a config,
module.exports = {
NODE_ENV: "production",
ROOT_API: "some api url"
}
The config should be accessible like this
process.env.ROOT_API throughout the app.

Refer the Pass Environment Variables section in the docs.
You can also provide environmental variables to the Webpack build:
$ tns build android --bundle --env.development --env.property=value
They can be accessed through the env object in the Webpack
configuration:
// webpack.config.js
module.exports = env => {
console.dir(env); // { development: true, property: 'value' }
}
You may update your DefinePlugin something like below,
new webpack.DefinePlugin({
"global.TNS_WEBPACK": "true",
"global.ENV_NAME": JSON.stringify(name),
"global.ENV_PROPERTY": JSON.stringify(env.property),
process: undefined,
}),
Now using global.ENV_PROPERTY anywhere in your project should be replaced by actual value you pass in command line at compile time.
If you are familar with webpack, you may also configure the CopyWebpackPlugin to copy right environment file to your app instead of having variable for each configuration.
