How to remove the TypeScript warning?

Question

npm

I wrote a small plugin for the fastify framework, but when I publish it to npm and then install it, it gives me such a warning?
so the thing is that I didn't use TypeScript, how to solve this?

Answer 1

Xs, what a fastify, but if it supports both js and ts, it can leave the care of types to someone who wants to use your plugin (although this is bad manners).
If it only uses ts, then using it you obviously need to know ts. In this case, do exactly what the console tells you: make an appropriate declaration file.
