Vue-router: Memory leaks

[OculusMode]

Version

2.5.0

Reproduction link

https://codesandbox.io/s/7wnmv7q9n1

Steps to reproduce

Simply navigate through tabs again and again

What is expected?

Memory should be preseved

What is actually happening?

Memory is increasing by time

[OculusMode]

I just found that giving type as email or password was causing it. Still is it expected behaviour of increasing in ram every time?

Please provide a minimal reproduction instead of a complex project. Remove anything that doesn't prevent reproducing the issue.

as @fnlctrl said, this is especially true with memory leak reports. Ideally, an html file is better, so it's easier to see create snapshots.

Closing until an appropriate repro is provided

@posva @fnlctrl i have created link with only needed code.

What is exactly the memory leak you are seeing? 🤨

[OculusMode]

@posva thanks for reply. I'm honestly not much deep into js.
So i can be totally wrong.
But in my code (previously given) when i was using input tag with type email and password memory kept increasing(very small amount like 0.2 to 0.5MB).

from new link(with if you'll navigate again and again you'll see result like this image.)

And if you remove type of input you'll see result like this image.

And im not sure is this the actual 'should be' behaviour?

Thanks for reply :)

I can see the same problem. I noticed this in my "real" application, so I looked if I can reproduce it with an unmodified project created by vue-cli using vue ui -> _create new Project_. It seems so, if I am not measuring the wrong things.

Versions
_Environment_
Node.js: 10.10.0
@vue/cli: 3.0.3 (to create the repro)

_Project (dependencies)_
vue: 2.5.17
vue-router: 3.0.1

_Project (devDependencies)_
@vue/cli-plugin-babel: 3.0.3
@vue/cli-service: 3.0.3
vue-template-compiler: 2.5.17

Reproduction link
https://github.com/hohlb/vue-router-memory-leak
Only the built project: https://github.com/hohlb/vue-router-memory-leak/tree/master/dist

Steps to reproduce

Simply navigate between "Home" and "About" routes by clicking them alternatively:

This is true for the devServer as well as the built site (built using npm run build --modern).

In Chrome's Taskmanager, you will see the increase in memory consumption. As @OculusMode described, you also see it in Chrome's DevTools, e.g. by comparing Heat Snapshots in Chrome.

I opened #2389 with a boiled down repro. It's really weird that it only happens with input[type=password]

Sorry to bother, has there been any progress on this since, we also noticed this memory leak as well and was wondering if there was any work around?

Same here. Please provide an update.
