Error Importing "mongodb" with typescript

Question

When compiling any typescript program that just imports mongodb, i get 12 errors like:

node_modules/mongodb/mongodb.d.ts:3309:5 - error TS2416: Property 'end' in type 'GridFSBucketWriteStream' is not assignable to the same property in base type 'WritableStream'

To reproduce is simple with node TLS (v16.13.1), & a empty directory, just run:

npm i mongodb typescript
echo "import mongodb  from 'mongodb'" > index.ts
npx tsc index

I think your example has a mistake. It should be import * as mongodb from 'mongodb' since mongodb does not have a default export. – Commerce

I'm encountering the same issue, though using Mongoose, which depends on MongoDB's native Node driver. The solution I came to was downgrading Mongoose to the last major release, which I assume downgraded the MongoDB driver. Not sure if that fits your usecase. – Embracery

I too just encountered this same error today. mongodb 4.2.2 Not using mongoose. – Mobilize

Thanks for the suggestion Sam, I changed the example to your suggestion, but got the same result – Mailable

Thanks Quontas, I can also get it to work with the v3.x.x of the mongdb driver, but none of the 4.x.x versions work! – Mailable

Answer 1

Looks like mongodb npm released 4.3.0 last night (2022-01-06) that now resolves this issue! changelog includes the issue here: #3088

v4 now compiles without these errors!

Answer 3

I have to downgrade my @types/node to version 17.0.0

"@types/node": "17.0.0", worked for me

Answer 4

mongodb 4.3.0 fix this issue for me. I use mongoose but I put "mongodb": "^4.3.0" in my dependencies to force the update. I don't know if this is the right thing to do but it works while waiting for mongoose to update.

Answer 5

I'm unable to reproduce your problem in my local environment, so I think it is a problem probably related to some other package in your project.

As suggested on this issue, you should try deleting your package-lock.json and generating it again with npm.

I tried this as suggested, and additionally, removed my "node-modules" folder. This did not solve the problem for me. – Mobilize

Thanks for your suggestion, I've just tried it on a 2nd machine, Ubuntu 21.04 again, with the same result. There is no package-lock.json before I run the "npm i mongodb typescript" it just gets the latest versions. I also tried to delete the $HOME/.npm folder with no luck. I dont understand it – Mailable
