Description

When using ESM with TypeScript the types are missing.

Example with this code:

import fastifyPassport from '@fastify/passport';

fastifyPassport.initialize()
fastifyPassport.secureSession()

fastifyPassport.use(undefined as any, undefined as any);

I get:

$ tsc --notEmit
src/index.ts:3:17 - error TS2339: Property 'initialize' does not exist on type 'typeof import("<repo-path>/node_modules/@fastify/passport/dist/index")'.

3 fastifyPassport.initialize()
                  ~~~~~~~~~~

src/index.ts:4:17 - error TS2339: Property 'secureSession' does not exist on type 'typeof import("<repo-path>/node_modules/@fastify/passport/dist/index")'.

4 fastifyPassport.secureSession()
                  ~~~~~~~~~~~~~

src/index.ts:6:17 - error TS2339: Property 'use' does not exist on type 'typeof import("<repo-path>/node_modules/@fastify/passport/dist/index")'.

6 fastifyPassport.use(undefined as any, undefined as any);
                  ~~~


Found 3 errors in the same file, starting at: src/index.ts:3

Steps to Reproduce

Repro

or:

1. run:

npm init -y

npm i typescript fastify @fastify/passport @types/node

./node_modules/.bin/tsc --init

2. add this to src/index.ts file:

import fastifyPassport from '@fastify/passport';

fastifyPassport.initialize()
fastifyPassport.secureSession()

fastifyPassport.use(undefined as any, undefined as any);

3. Add "type": "module" in package.json
4. in tsconfig.json replace "module": "commonjs" with "module": "Node16"
5. run tsc

Expected Behavior

should compile without errors

My bad, I also needed to add "moduleResolution": "Node" to the tsconfig compilerOptions

{
  // ...
  "compilerOptions": {
     //  ... 
     "moduleResolution": "Node",
     "module": "Node16",
   }
}
