Description

Why does connect localhost:27017 work.
but connect to mongo with the address mongodb+srv://user:pass@cluster0.m9frj.mongodb.net/
then get an error

Plugin file

  'use strict'

  const fp = require('fastify-plugin')
  const fastifyMongo = require('@fastify/mongodb')

  module.exports = fp(async function datasourcePlugin(fastify, opts, next) {

    try {
      fastify.register(fastifyMongo, {
        forceClose: true,
        connectTimeoutMS: 10000,
        url: fastify.secrets.MONGO_URL
      });
    } catch (err) {
      next(err);
    }
  }, {
    dependencies: ['application-config']
  })

Plugin did not start in time: '@fastify/mongodb'. You may have forgotten to call 'done' function or to resolve a Promise

Steps to Reproduce

1. config plugin and run with localhost => work
2. config with mongolab => error

Expected Behavior

This indicates that the connection to the db could not be established, as the plugin never resolves.

[hoanghiep1x0]

I have configured the db on mongo lap correctly because network open is 0.0.0.0 and user + password is correct. But I don't understand why it doesn't work

[hoanghiep1x0]

@Uzlopak But when working on localhost:27017 it runs again, can you help me? I just learned about fastify.

[climba03003]

I am closing the issue because there is no indication the problem related to fastify.
You can still comment on the issue or seek for helps on the Discord channel.

From my point of view, it clearly you have some connection error to your database, please try the same connection string with MongoDB Compass to see if your computer allowed to connect.

[hoanghiep1x0]

I am 100% sure the error is from @fastify/mongodb

Here is the code I run perfectly fine with mongoose

const mongoose = require("mongoose");

(async () => {
    try {
        await mongoose.connect('mongodb+srv://demo:demo@cluster0.m9frj.mongodb.net/')
        console.log("connect success");
    } catch (err) {
        console.log(err);
    }
})()

and here is the code that runs with fastify

'use strict'

const fp = require('fastify-plugin')
const fastifyMongo = require('@fastify/mongodb')

module.exports = fp(async function databaseConnect(fastify, opts) {
  fastify.register(fastifyMongo, {
    forceClose: true,
    url: 'mongodb+srv://demo:demo@cluster0.m9frj.mongodb.net/'
  })
}, {
  dependencies: ['application-config']
})

The result is the same as the error I posted

[Eomm]

was about to say that in your first code version you are mixin async and next, the latter version of the code should be fine.

I think it may be a firewall or something.
I would suggest to debug it with:

module.exports = fp(async function databaseConnect(fastify, opts) {
try{
  await fastify.register(fastifyMongo, {
    forceClose: true,
    url: 'mongodb+srv://demo:demo@cluster0.m9frj.mongodb.net/'
  })
} catch (err) {
console.log(err)
}
}, {
  dependencies: ['application-config']
})

[hoanghiep1x0]

I still get the same error.
One confusing thing is that it works with localhost:27017

while testing with mongoose new file index.js it works. If it's due to a firewall, mongoose will also not work. Because I am running on the same local machine environment.

[hoanghiep1x0]

const fp = require('fastify-plugin')
const fastifyMongo = require('@fastify/mongodb')

module.exports = fp(async function databaseConnect(fastify, opts) {
 try {
   await fastify.register(fastifyMongo, {
     forceClose: true,
     url: 'mongodb+srv://demo:demo@cluster0.m9frj.mongodb.net/'
   })
 } catch (err) {
   console.log("ERROR ===>",err)
 }
}, {
 dependencies: ['application-config']
})

Run -> ERROR ===> AvvioError [Error]: Plugin did not start in time: 'databaseConnect-auto-2'. You may have forgotten to call 'done' function or to resolve a Promise
at Timeout._onTimeout. :(

[climba03003]

I suggest you to try the official package mongodb instead of mongoose.

import { MongoClient } from 'mongodb'

const client = new MongoClient('mongodb+srv://demo:demo@cluster0.m9frj.mongodb.net/')
await client.connect()

[hoanghiep1x0]

Thank. I'm just testing to find the problem and fix it.

[hoanghiep1x0]

ERROR

'use strict'

const fp = require('fastify-plugin')
const fastifyMongo = require('@fastify/mongodb')

module.exports = fp(function datasourcePlugin(fastify, opts, done) {

A plugin does not fail

const mongoose = require("mongoose");

module.exports = fp(function databaseConnect(fastify, opts, done) {
  mongoose.connect('mongodb+srv://demo:demo@cluster0.m9frj.mongodb.net/').then(() => {

  })
  done();
}, {
  name: 'plugin-mongoose',
  dependencies: ['application-config']
})

[climba03003]

You are not doing the same as this plugin, and you ignore the connection state by resolving the plugin immediately.
The below one is waiting for the connection properly.

'use strict'

const fp = require('fastify-plugin')
const mongoose = require("mongoose");

module.exports = fp(function databaseConnect(fastify, opts, done) {
  mongoose.connect('mongodb+srv://demo:demo@cluster0.m9frj.mongodb.net/').then(() => {
    console.log("connect success");
    done();
  }).catch(err => {
    console.log("ERROR MONGOO CONNECT===>", err);
    done(err);
  })
}, {
  name: 'plugin-mongoose',
  dependencies: ['application-config']
})

I tried but doing the above will get an error.

[climba03003]

I tried but doing the above will get an error.

So, you would need to measure how much time you need to connect to the MongoDB Altas.

Increase the pluginTimeout to 30s or longer, if a single connection required more than 30s than it is absolutely something wrong in your network stack.

[hoanghiep1x0]

[hoanghiep1x0]

What is network classification error and how to fix it. You can specify the way or area to learn how to fix it

[hoanghiep1x0]

Thanks I know how to solve the problem maybe this is it. pluginTimeout

[climba03003]

The MongoDB Altas connection consist too many steps.

1. DNS Resolution
2. TCP / IP handshake
3. Authentication

Normally, a connection will be resolved within 1 second. More than 10 second will exist in a slow network.

[hoanghiep1x0]

Thank you very much. after fixing with options with pluginTimeout server it is working.

const fastify = Fastify({
  disableRequestLogging: true,
  logger: loggerOptions,
  ajv: {
    customOptions: {
      removeAdditional: 'all'
    }
  },
  connectionTimeout: 60000,
  requestTimeout: 60000,
  pluginTimeout: 90000
})
