Receiving intelligent suggestions for TypeScript interfaces declared within function parameters

Here is a simple example I put together:

In this example, intellisense provides suggestions for the interface of the object named test in the foo function. It works perfectly and I love it!

However, if you declare that interface somewhere else like this:

Intellisense only informs me that the test parameter has the Itest interface, but it does not provide details about its parameters.

So, in this scenario, how can I see the parameters of the interface "Itest" without having to open the file or search for compiler errors?

Answer №1

Unfortunately, the scenario you are trying to achieve is not feasible and would be highly impractical in real-life coding situations. Consider interfaces with a multitude of fields, each containing numerous subfields. The most efficient way to navigate through this complexity is by simply clicking on your function name and pressing f12 to reveal its declaration. Repeat this process for interface names as needed, and use alt + left arrow to navigate back.

Update: For jcalz's solution to function properly, ensure your cursor is positioned between the braces and press alt + space.
