Vscode-ng-language-service: newest release breaks intellisense.

[matrosovas]

0.1.11 broke intellisense and added ~1-2+second lag to it in typescript and html files. After reverting to 0.1.10 it works as expected.

I have the same problem. I was annoyed at how hard it was to find a link to download the previous version. GitHub release only has the beta version. For ppl, who wants to downgrade to v0.1.10:

I too was having issues with the newest version, but what is nice is that the newest version of VSCode now allows you to install older versions of packages.

Had the exact same problem. As @ic3guy pointed out, easy to flip back to 0.1.10. I was seeing a SEVERE slowdown over several seconds for every lookup - pretty much made it unusable. Went back to instant when I reverted.

[LucaSalzani]

for me the downgrade did not improve performance.

intellisense takes a long time to come up with the list of recommendations.

Reverting back to the previous version seems to help.

[nhustak]

This is still am a major issue and even 1.1.10 is now incredibly slow. It's like it never pre-loads it. It's hit or miss whether it remembers it. It doesn't automatically pop up anymore - I have to hit control space and literally sit for 8-12s for it to finally deliver my options. My app is fairly large (I guess?) but it doesn't seem atypical. Man this sucks.

[nhustak]

Today it spent almost 45s with the little thing at the top making its circuit before I gave up.

In case this helps, here's an Angular Language Service Dump. FYI, this is running off an SSD with 16 gig of ram.

This is a bit frustrating - it's been busted for months now. For me, installing a previous version doesn't fix the issue. It can take over 20 seconds for intellisense suggestions to appear, and I have to manually trigger with ctrl+space.

If I disable the extension, suggestions appear instantly.

So for now, I am going to completely disable the extension. I really hope someone can address this - I found it invaluable when it was working!

[nhustak]

@acidduckling Yep, I disabled it a couple of months ago so that at least regular typescript intellisense works. It pretty frustrating after having it to begin with - as you said, it's very very nice when it works. I'm really taken aback at the way the Angular team is ignoring this issue. It's seems a bit insane to ignore one of the top editors out there not to mention..well just flat out ignore the multiple threads. I mean, I get it...busy...but this seems pretty important.
