Is there a way to remove unused imports and declarations from Angular 2+? [closed]

Question

Edit (as suggested in comments and other people), Visual Studio Code has evolved and provides this functionality in-built as the command "Organize imports", with the following default keyboard shortcuts:

option+Shift+O for Mac

Alt + Shift + O for Windows

Original answer:

I hope this visual studio code extension will suffice your need: https://marketplace.visualstudio.com/items?itemName=rbbit.typescript-hero

It provides following features:

• Add imports of your project or libraries to your current file
• Add an import for the current name under the cursor
• Add all missing imports of a file with one command
• Intellisense that suggests symbols and automatically adds the needed imports "Light bulb feature" that fixes code you wrote
• Sort and organize your imports (sort and remove unused)
• Code outline view of your open TS / TSX document
• All the cool stuff for JavaScript as well! (experimental stage though, better description below.)

For Mac: control+option+o

For Win: Ctrl+Alt+o

As of Visual Studio Code Release 1.22 this comes free without the need of an extension.

Shift+Alt+O will take care of you.

If you're a heavy visual studio user, you can simply open your preference settings and add the following to your settings.json:

...
"editor.formatOnSave": true,
"editor.codeActionsOnSave": {
  "source.organizeImports": true
}
....

Hopefully this can be helpful!

To be able to detect unused imports, code or variables, make sure you have this options in tsconfig.json file

"compilerOptions": {
    "noUnusedLocals": true,
    "noUnusedParameters": true
}

have the typescript compiler installed, ifnot install it with:

npm install -g typescript

and the tslint extension installed in Vcode, this worked for me, but after enabling I notice an increase amount of CPU usage, specially on big projects.

I would also recomend using typescript hero extension for organizing your imports.
