Code action "source.addMissingImports" is extremely slow on save #208911
Description
Type: Performance Issue
The issue happens when saving a ts/tsx file that has missing imports, where I expect it to add the missing imports.
It takes over 20 seconds to save when it needs to add a couple of missing imports.
Show this message in the bottom right corner:
Saving 'Filename.tsx': Getting code actions from ''TypeScript and JavaScript Language Features'' (configure).
No extensions installed. I have tried complete reinstallation of VS Code and removed all local configuration (only addMissingImports enabled).
.vscode/settings.json:
{
"editor.codeActionsOnSave": {
"source.addMissingImports": "explicit",
},
}
tsconfig.json:
{
"compilerOptions": {
"lib": ["es2021", "dom", "dom.iterable"],
"types": ["node", "bun"],
"jsx": "preserve",
"target": "es2021",
"moduleResolution": "bundler",

"skipLibCheck": true,
"verbatimModuleSyntax": true
},
"exclude": ["dist", "helpers", "node_modules", "tailwind.config.ts", "vite.config.ts"]
}
Happens in workspace and also if I just open the particular project as a folder. I am not sure exactly when this started happening, as it has been happening from time to time, but right now happens consistently. When it was working fine it was instant.
