A very convenient tcp framework in golang.

• Have fun
• Heartbeat
• Auth
• User pool
• Graceful
• Middleware
• Message
• Marshaller
• TLS

Start

go get github.com/fwhezfwhez/tcpx

Dependency

if you want to run program in this repo,you should prepare protoc,proto-gen-go environment. It's good to compile yourself from these repos,but there is already release versions referring to their doc. Make sure run protoc --version available.

protoc: https://github.com/golang/protobuf

proto-gen-go:https://github.com/golang/protobuf/tree/master/protoc-gen-go

Pack

Tcpx has its well-designed pack. To focus on detail, you can refer to: https://github.com/fwhezfwhez/tcpx/tree/master/examples/modules/pack-detail

[4]byte -- length             fixed_size,binary big endian encode
[4]byte -- messageID          fixed_size,binary big endian encode
[4]byte -- headerLength       fixed_size,binary big endian encode
[4]byte -- bodyLength         fixed_size,binary big endian encode
[]byte -- header              marshal by json
[]byte -- body                marshal by marshaller

According to this pack rule, tcpx has 2 well-designed routing ways and their pack structure:

messageID type pack

header:
{
    "Router-Type": "MESSAGE_ID"
}

urlPattern pack

header:
{
    "Router-Type": "URL_PATTERN"
    "Router-Pattern-Value": "/login/"
}

Chat

https://github.com/fwhezfwhez/tcpx/tree/master/examples/modules/chat

It examples a chat using tcpx.

Raw

https://github.com/fwhezfwhez/tcpx/tree/master/examples/modules/raw

It examples how to send stream without rule, nothing to do with messageID/urlPattern system. You can send all stream you want. Global middleware and anchor middleware are still working as the example said.

IM

Here is an example of IM system using tcpx.
