[Bug] Frequent HMR frequent failures

[NathanaelA]

Environment

• CLI: 6.2.x (Been happening since 6.0)

• Cross-platform modules: 6.0 - 6.2.0

• Android Runtime: 6.0 - 6.2

• iOS Runtime: 6.0 - 6.3@next

• Plugin(s): None

• Node.js: 10.15.3

• Please, attach your package.json and webpack.config.js as these configurations are usually critical for investigating issues with webpack
  testvue.zip
  (Please note; these are STOCK from a newly created vue app -- so probably not the issue 😀)

Describe the bug
HMR fails the majority of time

To Reproduce

1. tns create testvue (Create empty vue stock app)
2. tns run android
3. Change the css background value

• First time almost always works; subsequent times fail the majority of the time

Notes:
@vakrilov and I surmise this might be a issue on Linux machine(s), we both did the exact same steps, both of us created a new stock vue app -- his machine HMR worked perfectly. My machine HMR failed.

• --no-hmr does not improve the situation much (if any).
• Plugin changes fail the majority of the time.
• ns-core apps normally work, but occasionally it will fail and continue failing, but ns-vue, ns-angular have frequent issues always.
• Frequently when HMR changes when fail to apply, it will also restart the app (without the changes)
• I have also seen this issue on Mac OSX also frequently.

Expected behavior
Always works 😀

Sample project
Just create a stock vue app

Additional context
Showed issue to @vakrilov at jsmobile conf

Hey @NathanaelA ,
Can you send us the output of tns run android --log trace and send us the generated output, so we can investigate the issue.
Also, can you try installing nativescript-dev-webpack@next and see if there will be improvement in this area.

1. Fresh TNS Run then a single CSS change;

Attached is the logs:

2. This is the second change; the app actually restarted and still was the color from above's successful change, not this css change.

Third Test (Upgraded to @next): nativescript-dev-webpack@1.4.0-next-2019-11-10-212313-01
The first change took, the second change took, the third & forth change did the same thing as above where the app reboots but the color from the last success (i.e. the second change) is what the color is...

@NathanaelA,

Sorry for the late reply and thanks for the provided logs!

We had a few similar issues in our 6.2 release and that's the main CLI-related improvement in 6.3. The problem was that we were not uploading all files during app restart which leads to an invalid app state with permanent old content (runtime.js which contains the HMR hash was not properly updated).

All of the issues were fixed in the 6.3 release and I suggest you try updating nativescript-dev-webpack, nativescript and your webpack.config.js to our rc versions. The official 6.3 release is planned for this weeks if we don't find any critical issue.

If you have a similar issue with the 6.3 versions, please attach the new log traces in order to allow us to investigate it further.
