Details

parodus

go-parodus has two main functions:

• maintain the websocket connection with talaria. Managing the websocket layer is handled via the kratos library which was originally developed for testing purposes.
• handle the nanomsg server with its clients. When a request comes from talaria, the wrp message is routed to the clients. For more information on how Parodus work refer to the Wiki

parodus clients

For creating a parodus client most of the work has already been done for you in the libparodus package by maintaining the nanomsg client to parodus. The consumer of the package will need to implement the kratos.DownstreamHandler interface

Examples

For the following examples the XMiDT cluster must be up and running. For local testing I recommend standing up a local docker cluster.

• request-response -> set and get information from a map
• event -> spam talaria with events generated from a client

Build

Source

In order to build from the source, you need a working Go environment with version 1.11 or greater. Find more information on the Go website.

You can directly use go get to put the go-parodus binary into your GOPATH:

GO111MODULE=on go get github.com/xmidt-org/go-parodus

You can also clone the repository yourself and build using make:

mkdir -p $GOPATH/src/github.com/xmidt-org
cd $GOPATH/src/github.com/xmidt-org
git clone git@github.com:xmidt-org/go-parodus.git
cd go-parodus
go build .
