Orbis Golang SDK

Orbis SDK is designed to help clients consume Orbis APIs with ease. Orbis SDK takes care of all the heavy lifting and provides out-of-the-box ready-to-use objects.

Installation

Make sure your project is using Go Modules (it will have a go.mod file in its root if it already is):

go mod init

Then, reference orbis-sdk-go in a Go program with import:

  import "github.com/OrbisSystems/orbis-sdk-go"

Go version of the SDK is 1.20

Run any of the normal go commands (build/install/test). The Go toolchain will resolve and fetch the stripe-go module automatically.

Alternatively, you can also explicitly go get the package into a project:

go get -u github.com/OrbisSystems/orbis-sdk-go

Documentation

Below are a few simple examples:

Orbis config

cfg := config.Config{
    Host:     "host-to-orbis-server", // ask client support. JUST hostname, without setting schema. Example: localhost, NOT https://localhost 
    LogLevel: config.TraceLogLevel,
}

Token storage

You can use redis

tokenStorage, err := storage.NewRedisStorage(storage.Config{
    Host: "localhost",
    Port: 6379,
})

or in-memory storage

tokenStorage := storage.NewInMemoryStorage()

Init AUTH system

authSys := auth.New(tokenStorage)

Set up the client

cli := client.NewSDK(cfg, authSys)

Auth

You can check do you need to loging

needToLogin, err := cli.Account.NeedToLogin(ctx)

For login use the next API

cli.Account.LoginByEmail(ctx, model.LoginByEmailRequest{
    Email:      "[email protected]",
    Password:   "passpass",
    DeviceID:   "devideID",
    RememberMe: true,
})

Also, you can use API Keys for loging using LoginByAPIKey method.

Client using

After login, you can use one of the many APIs we provide you via this client. Here are some examples:

News

response, err := cli.News.GetByFilter(ctx, model.NewsFilterRequest{
    Paging: model.Paging{
        Limit:  100,
        Offset: 2,
    },
})

TipRank

response, err := cli.TipRank.AnalystPortfolios(ctx, model.PortfoliosRequest{
    ExpertUID: "dwdqw31",
    Number:    12,
})

Logos

response, err := cli.Logos.SymbolLogos(ctx, "AAPL")

Funds

response, err := cli.Funds.GetFundDetails(ctx, "AAPL")

WebSocket

By using web socket connection you can get news feed from our system

newsCh, err := cli.WS.Subscribe(ctx, model.NewsSubscription)
if err != nil {
    log.Error(err)
    return
}

// newsCh is chan model.News

Example of working code for using Orbis System

package main

import (
	"context"
	"fmt"
	"time"

	"github.com/OrbisSystems/orbis-sdk-go/auth"
	"github.com/OrbisSystems/orbis-sdk-go/client"
	"github.com/OrbisSystems/orbis-sdk-go/config"
	"github.com/OrbisSystems/orbis-sdk-go/model"
	"github.com/OrbisSystems/orbis-sdk-go/storage"
)

func main() {
	// creating basic context
	ctx := context.Background()

	// set configs
	cfg := config.Config{
		Host:     "host-to-orbis-server",
		LogLevel: config.InfoLogLevel,
	}

	// init token storage using REDIS
	tokenStorage, err := storage.NewRedisStorage(storage.Config{
		Host: "localhost",
		Port: 6379,
	})
	if err != nil {
		panic(err)
	}

	// init auth system
	authSys := auth.New(tokenStorage)

	// create SDK Client
	cli := client.NewSDK(cfg, authSys)

	// check do we need to call Log In flow
	needToLogin, err := cli.Account.NeedToLogin(ctx)
	if err != nil {
		return
	}

	if needToLogin {
		// if we need to Log In - do it using email and password
		if err := cli.Account.LoginByEmail(ctx, model.LoginByEmailRequest{
			Email:      "[email protected]",
			Password:   "strong_password",
			DeviceID:   "qwqeqweq",
			RememberMe: true,
		}); err != nil {
			fmt.Println("login error")
		}
	}

	// get some latest news
	news, err := cli.News.GetByFilter(ctx, model.NewsFilterRequest{
		Paging: model.Paging{
			Limit: 10,
		},
	})
	fmt.Println(err)
	fmt.Println(news)

	// get some fund details for specific symbol
	fundDetails, err := cli.Funds.GetFundDetails(ctx, "AAPL")
	fmt.Println(err)
	fmt.Println(fundDetails)

	// create web socket subscription for getting news in realtime
	newsCh, err := cli.WS.Subscribe(ctx, model.NewsSubscription)
	if err != nil {
		fmt.Println(err)
		return
	}

	go func() {
		for {
			select {
			// reading news from web socket
			case wsNews := <-newsCh:
				fmt.Println(wsNews)
			}
		}
	}()

	time.Sleep(time.Hour * 48)
}
