Net provides a clojure foundation to implement asynchronous networking based on Netty.

It is much narrower in scope and features than aleph, which you might want to look into if you want a full-fledged asynchronous programming toolkit for clojure.

net is rather geared towards people with prior Netty knowledge wanting to keep the same workflow in, hopefully, idiomatic Clojure, and nothing but standard clojure facilities.

• Light facades around Netty concepts such as channels, pipelines, channel initializers and bootstraps
• Facilities to create TLS client and server contexts from PEM files
• Ring-like HTTP(S) server facade
• HTTP(S) client
• Simple interface to create TCP server with optional TLS support
• Clojure core.async support
• Memory-efficient transducers for collections of ByteBufs

Net now has full API Documentation and Guides.

    [[spootnik/net "0.3.3-beta34"]]

• Support SNI for TLS requests

• Add draining facilities for unexpectedly closed channels

• Reliability fixes in HTTP client
• Allow disabling of SSL certificate validation
• Allow more options to be supplied to the HTTP server

• Ensure lost clients do not result in filled core.async channel buffers

• Start introducing bridged channels for tighter integration between Netty and core.async.
• Ensure event-loop-groups can be parameterized
• Allow supplying query args as a map in HTTP requests

• Play nice with non-epoll systems

• Adapt net.http.client to match server behavior: responses contain a core.async Channel body
• Handle transforms over the body, i.e: help callers supply a transducer when requesting
• Better handle error conditions
• Add net.core.async/timeout-pipe to help ensure upstream feeds a channel fast enough

• Handle Netty out-of-band /bad-request requests from HttpObjectDecoder

• Improve behavior on early downstream channel closing

• Fix a memory leak when closing the body channel from a handler
• Add clojure tools.deps.alpha support

• Fix all reflection warnings
• Fix calls to deprecated signatures in Netty

• No more dependency on tools.logging
• Better dispatch for pipelines

• Depend on Netty 4.1.19.Final
• Add ByteBuf collection transducers
• Handle Http server callback on an executor
• Improve Netty facade
• Add ByteBuf manipulation tooling
• Circumvent CLJ-1814 as much as possible

• Depend on Netty 4.1.8.Final

• specs for http server options

• Small fixes

• Allow user-supplied executor for responses (thanks @mpenet).
• Fix HTTP-related regressions introduced by reflection work.

• Ensure all calls do not need reflection.
• Correctly terminate clients in tcp server shutdown fn.

• Break HandlerAdapter into several protocols

• Add documentation and guides
• Improved specs

• Rework HTTP support to be aligned with jet
• Provide a single HTTP server interface, which allows aggregating or streaming body content.

• Allow user-supplied max body size

• Bugfix release for 0.2.18
• More restrictive specs

• Convenience macros to create encoders and decoders.

• core.spec schemas instead of prismatic schema
• Rely on Netty 4.1.6
• Additional sugar for futures and channels

• CRHough (https://github.com/CRHough) for a number of small fixes.
• Max Penet (https://github.com/mpenet) for most of the reflection fixes.
