ability to use --bundle as the default

[cowboyd]

Is your feature request related to a problem? Please describe.
It seems to me that you're either using webpack to build your javascript, or you're not, and if you are, then it's really rare that you don't want to use the --bundle option. It's annoying to have to never forget to add this to every single command.

Describe the solution you'd like
Some way to set in nsconfig.json settings that --bundle is the default and to provide a --no-bundle option in the event that you don't want to bundle with webpack.

Describe alternatives you've considered

Right now, we work around this by having:

{
  "scripts": {
    "build:ios": "tns build ios --bundle",
    "build:android": "tns build android --bundle"
}

To wrap every native script command that you might want to use in order to ensure that the --bundle flag is set.

Hey @cowboyd,

We've already implemented such functionality in the NativeScript CLI. All you need is to install the next version of NativeScript CLI - npm i -g nativescript@next and add the following in your nsconfig.json file

{
    "useLegacyWorkflow": false
}

This will enable hmr by default for your project for all commands.

Awesome! That's good to know. It would be great to update the documentation to indicate that the old way is deprecated.

@cowboyd,

Here is the PR to the docs repo - https://github.com/NativeScript/docs/pull/1593.

I'm closing this as a duplicate to #4389.
