I'm trying to create a native addon for Node.js and when I include
#include <napi.h>
The Intelli Sense of VS Code says that it cannot detect where node_api.h is located (it's included by napi.h).
node-gyp build works well and it compiles. But I do not understand where is that header in the system and where node-gyp gets it from? I need to add the path to the Intelli Sense options and to better understand the process of building in general.
I'm playing with this code example.
I have run a full search on disk C (I'm on Windows 10), and found out that the header file node_api.h is located in
C:\Users\<UserName>\AppData\Local\node-gyp\Cache\<NodeVersion>\include\node
as well as other headers like v8.h.
If you delete that folder, node-gyp build no longer works. node-gyp configure downloads all headers again and restores the above mentioned folder.
You should take a look at node-addon-api module.
The headers can be included via require('node-addon-api').include or you can find it inside node_modules/node-addon-api folder.

Are you using extension ms-vscode.cpptools by Microsoft? Then you should just add the path for the header files used by napi to your include path in VSCode: Move your cursor over the include line with the error -> chose "Quick Fix" -> there should be an option for setting include path options (exact naming is language specific) -> new tab opens, add the path under "include path"
The header files are located in appdata as described by RussCoder.
