glsp-examples - minimal-theia - typo in README ?

[rsoika]

Is there a typo in the README for the minimal example?

The following command did not work:

 cd glsp-client && yarn && cd minimal-theia && yarn copy:server && cd ../..

I am not the yarn expert but I think that the instruction yarn copy:server can not work because the package.json file did not provide such a script.

Hi, yes you are correct there is a currently a typo (resp. no longer existing command) in the example readme.
There is a pending PR that fixes this. (eclipse-glsp/glsp-examples#96)

ok thanks,
I see that there are a lot of additional small changes in the minimal example. Maybe this is the reason why I got no success.

For example after wiping out everything and starting from scratch with an empty folder and just copy the minimal example, I succeeded to start theia (which was a great moment for me). But the next moment when I try to build it again using yarn the theia no longer starts and I see the following messages in my browser debug console:

Ok just recognized with your new version of the minimal-glsp-server-contribution.ts I got rid of that problem. Thanks!
