💬 Are the Getting Started docs updated?

I'm in the Getting Started section of the fastify docs: https://fastify.dev/docs/latest/Guides/Getting-Started/ in the "Your first server" section. I'm just copy pasting the code provided to get our first server running, here's my code:

// this version does not work
const fastify = require('fastify')({
  logger: true
})

// Declare a route
fastify.get('/', function (request, reply) {
  reply.send({ hello: 'world' })
})

// Run the server!
fastify.listen({ port: 3000 }, function (err, address) {
  if (err) {
    fastify.log.error(err)
    process.exit(1)
  }
  console.log(`Server is now listening on ${address}`)
})

// // this version does work
// module.exports = async (fastify, opts) => {
//   fastify.get("/", (req, reply) => {
//     reply.send('hi module.exports')
//   })
// }

I get this error when trying the CommonJS, ES6, and async await versions that were listed in the docs. I'm new to Fastify so I'm unsure what this error means.

But, I was able to find a working version, I was just curious why the ones listed in the docs weren't working for me.

Your Environment

• node version: 20
• fastify version: >=5.0.0
• os: Mac

Can you provide an Minimum Reproducible Example to support you better?

So far, from your error code; you are trying to use the fastify CLI, which expects that the exported item from your script is a method that matches the plugin interface

Hi, thanks for reaching back.

I'm not exactly sure how I can better improve my minimum reproducible example as I already copy-pasted my entire file (which isn't that long). Basically, I was just following along to the Getting Started guide in the docs. I ran:

npm install fastify

then copy pasted the code they provided. But I get an error when I run that code. If I comment the currently uncommented code and uncomment the code under the comment "this version does work" then I can successfully get the server running and get an output. Which is why I was wondering if the docs were updated.

Let me know how I can improve my minimum reproducible example better and if you have any more questions. Thank you.

Looks like you are using fastify-cli to run your code. You can run the code in the snippet above using command node [file-name].js

This section will tell you how to run using fastify-cli or you can check out the repo
