Since Firewings can be used in the Client SDK aswell as Firebase-Admin SDK, typing is a bit tricky.
We provide 2 type definitions, either for the Client SDK or the Admin SDK (both under constuction). Just add the relevant type definition file to your tsconfig.json:
"types": [ // For Client SDK "firewings/types/client", // For Admin SDK "firewings/types/admin" ]
We're a bit behind with typing - not all typings are available yet.
See the current typings here.
If you need more, please write them and contribute them with a PR!
