Consider using hterm for better terminal experience

[michaellee8]

Is your feature request related to a problem? Please describe.
The current web terminal that portainer provides is quite buggy, it often breaks when doing multi-line commands, and running terminal application like top and nano are certainly going to break.

Describe the solution you'd like
Is it possible to use a more featured web terminal emulator implementation like hterm https://chromium.googlesource.com/apps/libapps/+/master/hterm ? It is more mature, and has been used by wetty https://github.com/krishnasrinivas/wetty , a web terminal that provides flawless experience.

Describe alternatives you've considered
Ajaxterm/anyterm, but hterm(wetty) is definitely more featured

Additional context
I have read the source code here https://github.com/portainer/portainer/blob/develop/app/docker/views/containers/console/containerConsoleController.js , but can anyone explain what does the Terminal() refer to? Which library is being used?

Hi @michaellee8

Thanks for opening this feature request and for considering to contribute.

We're currently using xterm.js (https://github.com/xtermjs/xterm.js/) as our "terminal" library.

@michaellee8 what is status of this? I have also got lot of feedback from our users that console is too buggy.

@michaellee8 I find out that multi-line commands are at least fixed on recent version of Xterm.js so I created PR for update to it #2452

Keeping this issue open for considering another console library.
