The JetBrains Ktor 3.0 expertise, introduced October 10, might be accessed from begin.ktor.io. The most important change in model 3.0 is the swap to the kotlinx.io multiplatform library. This library affords a multiplatform API that may deal with information sources and offers capabilities together with working with recordsdata, utilizing compression, and extra. The kotlinx.io library additionally cuts down on pointless copying of bytes between ByteReadChannel, ByteWriteChannel, and community interfaces. This permits for extra environment friendly byte transformations and parsing, thus making room for future efficiency enhancements.
