Synse Client (Golang)

The official HTTP and WebSocket client for interacting with the Synse Server API, written in Go.

For details on the Synse Server API, see the API Documentation.

Installing

This package can be installed via go get

go get github.com/vapor-ware/synse-client-go

Using

Initializing

Both the HTTP and WebSocket client must be initialized with configuration options. These options identify the Synse Server instance to communicate with as well as set other connection-related capabilities (timeout, TLS, etc).

import "github.com/vapor-ware/synse-client-go/synse"

func main() {
	opts := &synse.Options{
		Address: "localhost",
	}

	client, err := NewHTTPClientV3(opts)
	// or client, err := NewWebSocketClientV3(opts)
}

API

The table below describes which API endpoint/event correspond with each client method.

Method	HTTP endpoint	WebSocket request
Status()	/test	request/status
Version()	/version	request/version
Config()	/v3/config	request/config
Plugins()	/v3/plugin	request/plugins
Plugin(string)	/v3/plugin/{plugin_id}	request/plugin
PluginHealth()	/v3/plugin/health	request/plugin_health
Scan(scheme.ScanOptions)	/v3/scan	request/scan
Tags(scheme.TagsOptions)	/v3/tags	request/tags
Info(string)	/v3/info/{device_id}	request/info
Read(scheme.ReadOptions)	/v3/read	request/read
ReadDevice(string, scheme.ReadOptions)	/v3/read/{device_id}	request/read_device
ReadCache(scheme.ReadCacheOptions)	/v3/readcache	request/read_cache
WriteAsync(string, []scheme.WriteData)	/v3/write/{device_id}	request/write_async
WriteSync(string, []scheme.WriteData)	/v3/write/wait/{device_id}	request/write_sync
Transactions()	/v3/transaction	request/transactions
Transaction(string)	/v3/transaction/{transaction_id}	request/transaction

Additionally, there are a few client methods which do not correspond to an API endpoint:

Method	Description
GetOptions()	Return the current config options of the client.
Open()	Open the WebSocket connection between the client and Synse Server. WebSocket client only.
Close()	Close the WebSocket connection between the client and Synse Server. WebSocket client only.
