Disable tsserver for Visual Studio Code?
Disable the "TypeScript and JavaScript Language Features" built-in extension to Visual Studio Code (for your current workspace or globally, as you desire). You can find this extension by going to the extension manager, selecting "Show Built-in Extensions" from the "..." menu, and looking in the "Features" section.
I have the problem when updating npm packages while VSCode is open.
For me this works: By turning on the setting typescript.disableAutomaticTypeAcquisition
tsserver.js can be tamed and CPU usage drops to 0% almost immediately.
