API package exposing contexts data

API package exposing contexts data.

Here is a first try, to discuss the structure of the API exposed to the user.

TODO:

• user documentation
• internal documentation to explain data flow (update https://github.com/podman-desktop/extension-kubernetes-dashboard/blob/main/docs/data-flow.md)
• more unit tests
• more data exposed
• publish package to npmjs

question: why redefining a custom interface vs using the one from podman-desktop API ?

[feloy]

The interface IDisposable is not defined in the extension-api.d.ts, only the class Disposable.

IDisposable is only defined in the internal packages/api module in Podman Desktop.

[benoitf]

but shouldn't it use that class as all the methods of the main core API ?

Creation of Disposable object here then should use static create(func: () => void): Disposable; ?

[feloy]

Yes, you are right. I'll change this way.

There is also another change I was considering. The kubernetes extension redefines a copy of the Disposable class (in the channel module for the moment). I'm considering to remove this definition, and use the implementation of the core instead (the only drawback is that it is not accessible in the webview). WDYT?

[benoitf]

here it could be added into https://github.com/podman-desktop/podman-desktop/tree/main/packages/webview-api

or as part of new TC39, for webview use this "official" Disposable interface rather than bringing a custom one

[feloy]

I rebased after merging #421, should now use Disposable from extension-api
