Hi, does anyone know how to add a button with function on the left bar of theia? thx!

Hi, I follow the example https://www.theia-ide.org/doc/Composing_Applications.html to create my own theia IDE. I want to add an extension to it but really don't know how to do.
After I copy the dependencies from package.json in https://www.theia-ide.org/doc/Authoring_Extensions.html example to my IDE's package.json, then using yarn to install the dependencies, it shows a lot of error message....
Does anyone know how to create an extension and add to IDE ? Thanks!

Error message:
"FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory"

@lihomahowareyou I find what is the problem, I should add the extension to package.json and put the extension folder to node_modules folder, thx!!

Hello :)
I've got a question about https://github.com/theia-ide/typescript-language-server, how to specify your own .tsconfig file there?
Vincent Fugnitto
Hi @kud, we've moved discussions to https://spectrum.chat/theia. I see you already opened the issue on https://github.com/theia-ide/typescript-language-server
Erwann Mest
Yep :D
I'm on spectrum too now
Do nmost VSC plugins work on Theia?
Marc Dumais
Hi @DouglasRMiles . Anecdotally, I would say yes. BTW, we have moved to Spectrum: https://spectrum.chat/theia?tab=posts . You should open a new topic there if you'd like to discuss this more.

Is there a lot of success with using the typescript-language-server (https://github.com/theia-ide/typescript-language-server) ?

If I run it with stdio and I issue a few commands, it shuts down after a few seconds without logging any error or warning.

I send initialize, and wait for reply, it replies correctly after sending a bunch of windows/log messages.
I then pause 5 seconds, it terminates the process.

If I don't pause and continue sending initalized, and then didOpen commands it crashes at about the same time distance into the overall runtime (5-6 seconds).

It is running on TS Server 3.7.3, Node 12.13.0, Mac OSX

THe tsls log shows no error and just has a last log message that appears normal, and the ti-NNNN.log says the parent process has exited, so shutting down.

Not sure where to look for potential problems. I'm manually sending only a few commands and it just dies.

Running with --sockets doesn't start up at all, so can't try that.

Node 10.x fails too.

Hi As anyone used Spectron to test Theia IDE running as Electron app ?
I am facing an issue with multi-user eclipse/che when I am using che-theia with Java maven workspace mvn build and other tasks are working fine. I have set workspace idle timeout as well to 30 min but if I leave the screen idle for sometime(<30 mins) and then click on any of the tasks its failing with Request timeout. I am using 7.17.0 version of che. Any suggestions why this is happening and what can be done to fix this. Point to note workspace is active it's only tasks that are failing.
Florent BENOIT
@chaitu454 Maybe related to eclipse/che#18134 (but you should discuss on https://mattermost.eclipse.org/eclipse/channels/eclipse-che for che or the github che issue as it's not related to theia)
@benoitf Thank you
