Back-end Developer
Back-end DeveloperContributions:10 commits, 6 PRs, 19 comments in 2 years 2 months
Contributions summary:Kamil contributed to the `sttp` library by adding support for using existing HTTP clients within various backends. This included adding `resourceUsingClient` and `scopedUsingClient` methods to backends like `HttpClientFs2Backend`, `HttpClientMonixBackend`, `HttpClientZioBackend`, and others. These changes allowed users to integrate sttp with pre-existing HTTP clients in resource-managed environments. They also refactored code to use `Dispatcher.parallel` for concurrency and updated the code to use the org.scalajs.dom.File class.
