While they don’t specifically say what the “language server” is, if it’s the same protocol that powers VS Code[1], this is a big deal. It potentially means that language owners can build tooling that works across IDEs much more easily. Historically, JetBrains seems to have resisted the idea of a standard language protocol (which makes sense as it comes from Microsoft). My guess is it’s becoming impractical to reimplement every language feature for Typescript, C#, Go, etc. Embracing the standard LSP will mean less time spent on low level features and more time building JetBrains only value add.

At least with TypeScript, they've been using the official language server for a while. Sadly they still fall back onto their own JS-esque 'guess what this could be' mode in some situations where vanilla TS would have just emitted an error that the respective module could not be found.

For C# Rider supports Roslyn analyzers and code fixers as well, though I don't know with what performance impact (as ReSharper isn't based on Roslyn this results in all analysis work being done twice, which can be noticeable).

IMO, WebStorm's TS support is much better than VSCode's, especially the refactorings.

Yeah it really works well with angular as well

LSP is trash compared to intellij's tech

it is night and day..

i don't understand how people believe LSP is perfect, it is not, the API is broken, it missing a ton of stuff and as a result client implementations are often broken

What LSP is missing?

[mmargerum]

now that we have LSP running as an external process I hope they jettisoned java and are instead using C/C++/Skia or something for the editor so it's fast.

How do you know that it is java that is making it slow? Do you work for jetbrains?
