Dependency not picked up for module 'fastify'

[andyli]

I tried to generate extern for fastify by

npx dts2hx fastify --output lib/dts2hx

It outputted a bunch of errors:

I tried installing @types/node and running npx dts2hx @types/node fastify --output lib/dts2hx, but that didn't help. Am I missing something?

My dts2hx version:

dts2hx 0.15.3 alpha using TypeScript 3.7.4

hmm, not sure why it's not picking up the node dependency automatically, to resolve in the short term, open node_modules/fastify/fastify.d.ts and add /// <reference types="node" /> to the very top. Do the same for light-my-request/index.d.ts

Then run npx dts2hx fastify and it will work

I will explore what went wrong for it to miss the node dependency here
