VsCode extension - get list of dark/light themes

Question

Is it possible to get list of installed light/dark themes in extension programmatically.

I want to make an extension that will switch next color theme on key command.

Answer 1

You can get all extensions and search for the ones that contribute a theme:

vscode.extensions.all.forEach(ext => {
    console.log(ext.packageJSON.contributes.themes);
}
