💻 Examples

Subscribe to Account

Simple example on how to monitor an account for transactions with explanations.

package main

import (
  "context"
  "github.com/weeaa/goyser"
  "github.com/weeaa/goyser/pb"
  "log"
  "os"
  "time"
)

const subAccount = "EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"

func main() {
  ctx := context.Background()

  // get the geyser rpc address
  geyserRPC := os.Getenv("GEYSER_RPC")

  // create geyser client
  client, err := goyser.New(ctx, geyserRPC, nil)
  if err != nil {
    log.Fatal(err)
  }

  // create a new subscribe client which is tied, for our example we will name it main
  // the created client is stored in client.Streams
  if err = client.AddStreamClient(ctx, "main"); err != nil {
    log.Fatal(err)
  }

  // get the stream client
  streamClient := client.GetStreamClient("main")
  if streamClient == nil {
    log.Fatal("client does not have a stream named main")
  }

  // subscribe to the account you want to see txns from and set a custom filter name to filter them out later
  if err = streamClient.SubscribeAccounts("accounts", &geyser_pb.SubscribeRequestFilterAccounts{
    Account: []string{subAccount},
  }); err != nil {
    log.Fatal(err)
  }

  // loop through the stream and print the output
  for out := range streamClient.Ch {
    // u can filter the output by checking the filters
    go func() {
      filters := out.GetFilters()
      for _, filter := range filters {
        switch filter {
        case "accounts":
          log.Printf("account filter: %+v", out.GetAccount())
        default:
          log.Printf("unknown filter: %s", filter)
        }
      }
    }()
    break
  }

  time.Sleep(5 * time.Second)

  // unsubscribe from the account
  if err = streamClient.UnsubscribeAccounts("accounts", subAccount); err != nil {
    log.Fatal(err)
  }
}
