The JetBrains Ktor 3.0 expertise, introduced October 10, might be accessed from begin.ktor.io. The largest change in model 3.0 is the change to the kotlinx.io multiplatform library. This library provides a multiplatform API that may deal with information sources and supplies capabilities together with working with information, utilizing compression, and extra. The kotlinx.io library additionally cuts down on pointless copying of bytes between ByteReadChannel, ByteWriteChannel, and community interfaces. This enables for extra environment friendly byte transformations and parsing, thus making room for future efficiency enhancements.
SSE can be now supported for each the server and the shopper. With SSE, servers push shoppers over an HTTP connection and SSE supplies a one-way communication channel. This strategy is helpful for eventualities the place the server must ship event-based updates without having the shopper to repeatedly ballot for brand new info.
