Open own extension in VSCode Web with parameters

[gbrueckl]

Hi everyone,

I have developed a VSCode extension for the web which I want to start from an external application by passing parameters to it.
The only thing about this scenario I found was the UriHandler but it does only seem to work for vscode://... URIs but not for https://vscode.dev/...
According to the docs this is possible https://code.visualstudio.com/docs/setup/vscode-web#_more-custom-urls
but I am not sure if this only works for a pre-defined/whitelisted set of extensions?

I was hoping to be able to do something like https://vscode.dev/myPublisher.myExtensions/myCommand?param1=Hello%20World
Is this possible at all?

regards,

Hi @gbrueckl ,

I'm not sure there is a pre-defined/whitelisted set of extensions, at least not based on the documentation, as it says ...you can customize.... And, if not required, I suppose you should at least have the extension installed on your vscode.dev instance/window/session, in order to make it register your custom URL.

Have you installed it? Did you test using side loading or using the web option?

Hope this helps

yes, I also tried to install it manually up-front but still there is no way I could get it to open automatically.

It might just be a problem that it is simply not documented how the URL would need to be built in order to open a custom extension.
Do you happen to have any example there?

I just have developed local UrlHandlers, unfortunately. The only open source extension I remember upfront using UriHandlers is GistPad, and looking at its source code, it only has local support as well for now (https://github.com/lostintangent/gistpad/blob/master/src/uriHandler.ts).

Let’s see if other extension authors have something to share, or even if some of the VS Code team member could help on this one.

yes, I have implemented a the same UriHandler code in my extension which also works fine locally or with vscode:// URLs.
so the question is if this is also supposed to work with https://vscode.dev/... and if so, how the actul URL would need to look like
