PSA: Extension is no longer needed because this feature has been implemented natively

[nathanpovo]

For anyone else that stumbles across this extension/repository: this extension is no longer needed because the feature has been implemented natively in VS Code.

Simply add the following settings to your settings file

"javascript.inlayHints.enumMemberValues.enabled": true,
"javascript.inlayHints.functionLikeReturnTypes.enabled": true,
"javascript.inlayHints.parameterNames.enabled": "all",
"javascript.inlayHints.parameterTypes.enabled": true,
"javascript.inlayHints.propertyDeclarationTypes.enabled": true,
"javascript.inlayHints.variableTypes.enabled": true,
"typescript.inlayHints.enumMemberValues.enabled": true,
"typescript.inlayHints.functionLikeReturnTypes.enabled": true,
"typescript.inlayHints.parameterNames.enabled": "all",
"typescript.inlayHints.parameterTypes.enabled": true,
"typescript.inlayHints.propertyDeclarationTypes.enabled": true,
"typescript.inlayHints.variableTypes.enabled": true

or search for "inlay" in the settings UI and toggle the settings from there.

Toggling the hints will look as follows:

Parameter type inlay hints

Variable type inlay hints

Property type inlay hints

Return type inlay hints
