vscode-twoslash-queries

A tiny extension for VS Code that lets you use // ^? inside your editor to inline highlight types. Re-uses the existing TypeScript tooling infra in *.ts, *.tsx, *.js, and *.jsx files, simply adding inline info.

Useful for keyboard warriors or folks working on complex types and want to see how changes propagate throughout other types.

Features

Key: You write // ^? anywhere in a source file (with whitespace before, between and middle being whatever) all that matters is the alignment of the ^.

In addition:

• End a line with //=> to highlight the leftmost named type.
• Use the "TwoSlash Query: Insert Below" command from the Command Palette or assign a keyboard shortcut to it (default: Ctrl+K 6 on Windows, Cmd+K 6 on Mac).

You can see here it in use a few times:
