Tsoogle - like google but for your typescript project.
Find functions or methods by approximate signature - return type, argument types or both. Supports optional arguments, rest arguments and partial type checking.
Run the Tsoogle Search (cmd + shift + p and write Tsoogle)
A webview will be opened where you need to put the absolute filepath to your tsconfig.json file.
Then you can search for functions or methods using the tiny tsoogle query language.
Please refer to the tsoogle main repo for more information, how to query, etc. https://github.com/stanimirovv/tsoogle
