Getting started

Go Version

go-swan-sdk requires Go version 1.21 or above.

Swan API Key

To use swan-sdk, an Swan API key is required. Steps to get an API Key:

• Go to Swan Console, switch network to Swan Chain Mainnet.
• Login with your wallet.
• Click API Keys -> Generate API Key

Using go-swan-sdk

With Go's module support, go [build|run|test] automatically fetches the necessary dependencies when you add importin your project:

import "github.com/swanchain/go-swan-sdk"

To update the SDK use go get -u to retrieve the latest version of the SDK:

go get -u github.com/swanchain/go-swan-sdk

Quickstart

To use go-swan-sdk, you must first import it, and you can create and deploy instance applications quickly.

package main

import (
	"github.com/swanchain/go-swan-sdk"
	"log"
	"time"
)

func main() {
	client, err := swan.NewAPIClient("<YOUR_API_KEY>")
	if err != nil {
		log.Fatalf("failed to init swan client, error: %v \n", err)
	}
	task, err := client.CreateTask(&swan.CreateTaskReq{
		PrivateKey:   "<PRIVATE_KEY>",
		RepoUri:      "https://github.com/swanchain/awesome-swanchain/tree/main/hello_world",
		Duration:     2 * time.Hour,
		InstanceType: "C1ae.small",
	})
	taskUUID := task.Task.UUID

	// Get task deployment info
	resp, err := client.TaskInfo(taskUUID)
	if err != nil {
		log.Fatalln(err)
	}
	log.Printf("task info: %+v \n", resp)

	//Get application instances URL
	appUrls, err := client.GetRealUrl(taskUUID)
	if err != nil {
		log.Fatalln(err)
	}
	log.Printf("app urls: %v \n", appUrls)
}

Usage

New client

client, err := swan.NewAPIClient("<SWAN_API_KEY>")

Fetch all instance resources

Through InstanceResources you can get a list of available instance resources including their region information. You can select one you want to use.

instances, err := swan.InstanceResources(true)

Note: All Instance type list can be found here

Create and deploy a task

Deploy a application, if you have set PrivateKey, this task will be payed automaiclly, and deploy to computing providers on Swan Chain Network:

task, err := client.CreateTask(&CreateTaskReq{
    PrivateKey:   "<YOUR_WALLET_ADDRESS_PRIVATE_KEY>",
    RepoUri:      "<YOUR_PROJECT_GITHUB_URL>",
    Duration:      2 * time.Hour,
    InstanceType: "C1ae.small", 
})

taskUUID := task.Task.UUID
log.Printf("taskUUID: %v", taskUUID)

Access application instances of an existing task

You can easily get the deployed application instances for an existing task.

// Get application instances URL
appUrls, err := client.GetRealUrl("<TASK_UUID>")
if err != nil {
	log.Fatalln(err)
}
log.Printf("app urls: %v", appUrls)

A sample output:

['https://krfswstf2g.anlu.loveismoney.fun', 'https://l2s5o476wf.cp162.bmysec.xyz', 'https://e2uw19k9uq.cp5.node.study']

It shows that this task has three applications. Visit the URL in the web browser you will view the application's information if it is running correctly.

Renew duration of an existing task

RenewTask extends the duration of the task before completed

resp, err := client.RenewTask("<TASK_UUID>", <Duration>,"<PRIVATE_KEY>")

Terminate an existing task

You can early terminate an existing task and its application instances. By terminating task, you will stop all the related running application instances and thus you will get refund of the remaining task duration.

resp, err := client.TerminateTask("<TASK_UUID>")

Check information of an existing task

You can get the task details by the taskUUID

resp, err := client.TaskInfo("<TASK_UUID>")

Check all task list information belonging to a wallet address

You can get all tasks deployed from one wallet address

total, resp, err := client.Tasks(&TaskQueryReq{
    Wallet: "<WALLET_ADDRESS>",
    Page:   0,
    Size:   10,
})
