With +Gun 2.0 it is possible to make requests or data go through +any number of proxy endpoints using any combination of +TCP or TLS transports and HTTP/1.1, HTTP/2 or SOCKS5 +protocols. All combinations of the scenario Proxy1 -> +Proxy2 -> Origin are tested and known to work. + +You can watch a demo of the tunnel support below. This +video is the first of its kind. If you like it, or you +don't like it, please tell me! I intend to continue +producing those on a semi-regular basis. Watch: + +++++ + +++++ + +Gun 2.0 can now be used to send and receive raw data, +as if it was just a normal socket. This can be +useful when needing to connect through a number +of HTTP/SOCKS5 proxies, allowing the use of Gun's +great proxying capabilities for non-Web protocols. +This can also be useful when performing HTTP/1.1 +Upgrade to custom protocols. + +Gun 2.0 adds many more features such as Websocket over +HTTP/2, Websocket protocol negotiation, a built-in +cookie store, graceful shutdown, flow control for +data messages, event handlers and more. + +Gun 2.0 greatly improves the HTTP/2 performance when it +comes to receiving large response bodies; and when receiving +response bodies from many separate requests concurrently. + +Gun 2.0 will be more responsive in the event of connection +failures. It now checks return values from send calls and +has send timeouts enabled by default. For HTTP/2 a new +option allows Gun to drop the connection when pings do +not get a response in a timely manner. + +Gun now shares much of its HTTP/2 code with Cowboy, +including the HTTP/2 state machine. Numerous issues were +fixed as a result because the Cowboy implementation was +much more advanced. + +The Gun connection process is now implemented using `gen_statem`. + +The `gun_pool` module is a significant experimental feature +that allows users to create pools of connections. Pools +are split by authority and a user-provided token, allowing +users to reuse connections in a similar way to what Web +browsers are doing. Please check it out and provide feedback! + +Gun 2.0 requires Erlang/OTP 22.0 or greater and is tested +and supported on Linux, macOS and Windows. + +A complete +list of changes can be found in the migration guide: +https://ninenines.eu/docs/en/gun/2.0/guide/migrating_from_1.3/[Migrating from Gun 1.3 to 2.0]. + +I will now focus on implementing HTTP/3 and QUIC, first +in Cowboy and then in Gun. + +You can donate to this project via +https://github.com/sponsors/essen[GitHub Sponsors]. + +As usual, feedback is appreciated, and issues or +questions should be sent via Github tickets.
