Fastify plugin fastify-autoload error plugin must be a function

I have setup the fastify framework with fastify-cli library with command fastify-cli generate. It has fastify-autoload plugin used out of the box.

But, it will throw an error when I add my own service with exception for model.js and schema.js files.

...
fastify.register(AutoLoad, {
    dir: path.join(__dirname, 'services'),
    options: Object.assign({}, opts),
    ignorePattern: /.*(model|schema)\.js/
})
...

Error message:

assert.js:788
    throw newErr;
    ^

AssertionError [ERR_ASSERTION]: ifError got unwanted exception: plugin must be a function
    at wrap (D:\project\kuisioner\backend\node_modules\fastify-cli\start.js:124:5)
    ...
      actual: Error: plugin must be a function
    ...
    error Command failed with exit code 1.
    ...

But it will run smoothly when I register it manually

...
fastify.register(require('./services/quiz/get'))
fastify.register(require('./services/quiz/post'))
...

My file structure:

- src
  - plugins
    - db.js
  - services
  | - quiz
  |   - get.js
  |   - model.js
  |   - post.js
  |   - schema.js
  - app.js

I use fastify-cli fastify start -l info src/app.js to run my code

Here's my repo https://github.com/nnfans/kuisionerid_backend

according to docs, if you are using node with tsx you should change your command:

node --import=tsx server.ts

for

tsx server.ts

May be If you have accidentally create a empty route file this issue will happens and it persist on the dist ( Mostly you are using TypeScript ) This empty route file not returning functional output. As yonadav bar ilan said you have to delete dist and try to re-run it.

if you got here and you use typescript, maybe try to delete the dist dir and re-run tsc, you might have had a bad route that persisted there

Checking your repo the error is the dir value. You must point to the dir with the files, it is not supported the recursive loading yet

  fastify.register(AutoLoad, {
    dir: path.join(__dirname, 'services/quiz'), 
    options: Object.assign({}, opts),
    ignorePattern: /.*(model|schema)\.js/
  })

With this change, the npm start will work.

Another option is to use module.exports.autoload = false in the files that need to be skipped, but your regex is ok.
