Are you trying to import the package on the client side? because that's no suppose to work..

[acai2046]

With introduction

[leibale]

@acai2046 what do you mean by "With introduction"? Can you please share a little bit more? Thanks

[AlokBisht]

I am facing the same issue. when using redis with the nextjs project. however it works fine in a demo node app. any suggestions why the "URL" is undefined with nextjs app?

[leibale]

@AlokBisht make sure not to use the redis client from the client side, it only works on the server side (node, deno, ...)

[AlokBisht]

yeah, it's not on client side. I am just using syntax like this issue and passing a URL. like so many other reported issue, it seems there is some kind of type conflict happening due to some dependency in my project. that's my best guess after spending hours on this issue.

I tried using "ioredis" as well. it works but I see "TypeError: (0 , tls_1.connect) is not a function". so there is some dependency arrangement which is causing the types to be lost.

[leibale]

@AlokBisht I don't think that it's a type error, feels like there is actual code that is missing.. can you please create a repo that reproduces the issue so I'll be able to debug it?

[AlokBisht]

My issue is resolved now. you were right @leibale the redis code was reaching client side cause one of the wrong reference in code. hence I was getting the error on browser only the node console was clean. it works fine after I removed the wrong code ref.

[Tankonyako]

Have same, and this code working only on server side, and problem is

require('url') gives Url not URL
