Description

Hello.
I launched a clustered mongodb and enabled authentication.
But the fastify-mongodb plugin does not connect with authentication (AuthenticationFailed).
But there is no problem with MongoClient.

Steps to Reproduce

const fastify = require("fastify");
const app = fastify();

app.register(require('fastify-multipart'))
app.register(require('fastify-formbody'))
app.register(require('./FastifyRouter'))

//database
app.register(require('fastify-mongodb'), {
    forceClose: true,
    url: 'mongodb://localhost:27017/db',
    auth: {
        username: "username",
        password: "password"
    }
})

app.listen(port,"hostname",(err,adrs) => {
    if (err) {
        console.log(err)
    } else {
        console.log(address)
    }
})

Expected Behavior

No response

I think you should setup correctly the url parameter such as mongodb://localhost:27017/test?authSource=admin

[Sudo Dios]

I used this but it did not work :
mongodb://user:pass@localhost:27017/test.

You may write a complete url with the parameters.
(With this new url you mentioned)
(username & password)

Do not have a solution?

I'm afraid no one owes you a solution in any given timeframe.

How do you connect with basic MongoClient?

[Sudo Dios]

How do you connect with basic MongoClient?

Yes. can connect.
with this url :
mongodb://user:pass@localhost:27017/test

[Sudo Dios]

An irrelevant question 🙂:
Does fastify clustering have an effect at higher speeds ?

Yes. can connect. with this url : mongodb://user:pass@localhost:27017/test

From my knowledge of mongodb, it means that your account is stored in test db?
If that is the case, your connection string with mongodb://localhost:27017/db is actually authenticating against db which is expected to be fail.

I think simply pass mongodb://user:pass@localhost:27017/test into url is fine. The option is directly pass to MongoClient, if it can connect in MongoClient, it must be able to connect for fastify-mongodb.

I even tested in mongodb compass and authentication was done.
But not in fastify-mongodb.

I even tested it without considering the database, but it didn't work :
mongodb://user:pass@localhost:27017

[Sudo Dios]

You can also take a test ?

You can also take a test ?

I always use a single url which contain both credential, host and options to connect the database.
I do not have any problem with it. You can setup a repro with docker to simulate the error.
Or provide the code you are using, which I can connect my database to test it.

Can you write me a complete URL with options?

Note that if you do not specify database or authSource, Mongodb Compass by default using admin.

Which is actually mongodb://user:pass@localhost:27017/?authSource=admin

[Sudo Dios]

Thankful.
I will take the test again and report here

[KaKa]

Connection String is form like below
https://docs.mongodb.com/manual/reference/connection-string/#components

mongodb://<username>:<password>@<host>:<port>/[default database]?[<options>]

Note that if username or password contain : / ? # [ ] @ please encode your username and password.

[Sudo Dios]

Okey.
thanks

[Sudo Dios]

I tested and authentication was successful 👍.
I just had to add the last URL authSource = admin

[kkkkh]

Note that if you do not specify database or authSource, Mongodb Compass by default using admin.

if you want to link a new created db, you must add ?authSource=admin
I tried ,this is right
