Can not use integrated terminal when running locally

Hello Ivan,

Running kexp locally I am not able to use the integrated terminal.

kexp version:

$ kexp --version

When I click on the Terminal button - it opens just a black block without any prompt. Tried with Google Chrome and Firefox:

Thanks,

Hi @vlgermanov! Yes, I'm afraid it's not supported yet. The primary use case for kexp so far has been labs.iximiuz.com, where one can easily get a link for a web terminal session of the playground via an API call. kexp leverages the iximiuz Labs API and simply embeds an iframe with the link it gets in the response. When I use kexp outside of the Labs, I often pair it with github.com/yudai/gotty. With gotty, it's also easy to get a link for a web term session, but some hardcoding is required then to make kexp use it.

A "plug-in" web term implementation may solve the problem. On different environments, different means can be used to obtain a session URL (the native iximiuz Labs API, manually obtained gotty link, and even built-in web term implementation). Contributions are always welcome!

Hello, @iximiuz is there any way to pass the URL of the Iframe, when running kexp locally ? can it get passed down as parameter or is there any config param where i can set the terminal URL to be embedded inside the UI ??
Thank you

[ayoub-tl]

Never mind i found it, i replaced the URL WebTerm.vue Line 31 with as static Webterminal url

[iximiuz]

Hey @ayoub-tl - yes, that's pretty much what I do when I test kexp locally. Usually, I start a separate https://github.com/yudai/gotty process and then just hardcode the URL that it produces. Ideally, of course, it should be "out-of-the-box" behavior. Hopefully, I'll find time to implement it soon, or someone could open a PR.
