# Introduction
The `twenty-client-sdk` is always provided and injected at runtime by
the twenty-server instance
Which mean that even if in your app locally you're using
twenty-client-sdk `1.0` installing this app on twenty instance `2.0`
will result in injecting another `twenty-client-sdk`
That's the expected behavior and tradeof
The twenty-app devdep should only be used to guide local devxp following
typesafety and so on
A user can still locally generated its own twenty-client-sdk and publish
it if necessary
