# Spot

StreamManagerV2を使用してspot market module関連データをindexerからストリーミングするコードスニペットの例です。

## StreamManagerV2を使用したgRPCストリーム

### Orderbookの更新をストリーミング

```ts theme={null}
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import { 
  StreamManagerV2,
  IndexerGrpcSpotStreamV2 
} from '@injectivelabs/sdk-ts/client/indexer'

const endpoints = getNetworkEndpoints(Network.Testnet)
const stream = new IndexerGrpcSpotStreamV2(endpoints.indexer)

const streamManager = new StreamManagerV2({
  id: 'spot-orderbook-updates',
  streamFactory: () => stream.streamOrderbookUpdates({ 
    marketIds: ['0x...'],
    callback: (response) => {
      streamManager.emit('data', response)
    }
  }),
  onData: (orderbookUpdates) => {
    console.log(orderbookUpdates)
  },
  retryConfig: { enabled: true }
})

streamManager.on('connect', () => console.log('Stream connected'))
streamManager.start()
```

### Spot orderをストリーミング

```ts theme={null}
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import { OrderSide } from '@injectivelabs/sdk-ts/types'
import { 
  StreamManagerV2,
  IndexerGrpcSpotStreamV2 
} from '@injectivelabs/sdk-ts/client/indexer'

const endpoints = getNetworkEndpoints(Network.Testnet)
const stream = new IndexerGrpcSpotStreamV2(endpoints.indexer)

const streamManager = new StreamManagerV2({
  id: 'spot-orders',
  streamFactory: () => stream.streamOrders({
    marketId: '0x...',
    subaccountId: '0x...', // オプション
    orderSide: OrderSide.Buy, // オプション
    callback: (response) => {
      streamManager.emit('data', response)
    }
  }),
  onData: (orders) => {
    console.log(orders)
  },
  retryConfig: { enabled: true }
})

streamManager.on('connect', () => console.log('Stream connected'))
streamManager.start()
```

### Spot order historyをストリーミング

```ts theme={null}
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import {
  TradeDirection,
  TradeExecutionType,
} from '@injectivelabs/sdk-ts/types'
import { 
  StreamManagerV2,
  IndexerGrpcSpotStreamV2 
} from '@injectivelabs/sdk-ts/client/indexer'

const endpoints = getNetworkEndpoints(Network.Testnet)
const stream = new IndexerGrpcSpotStreamV2(endpoints.indexer)

const streamManager = new StreamManagerV2({
  id: 'spot-order-history',
  streamFactory: () => stream.streamOrderHistory({
    marketId: '0x...', // オプション
    subaccountId: '0x...', // オプション
    direction: TradeDirection.Buy, // オプション
    executionTypes: [TradeExecutionType.Market], // オプション
    callback: (response) => {
      streamManager.emit('data', response)
    }
  }),
  onData: (orderHistory) => {
    console.log(orderHistory)
  },
  retryConfig: { enabled: true }
})

streamManager.on('connect', () => console.log('Stream connected'))
streamManager.start()
```

### Spot tradeをストリーミング

```ts theme={null}
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'
import { TradeDirection } from '@injectivelabs/sdk-ts/types'
import { 
  StreamManagerV2,
  IndexerGrpcSpotStreamV2 
} from '@injectivelabs/sdk-ts/client/indexer'

const endpoints = getNetworkEndpoints(Network.Testnet)
const stream = new IndexerGrpcSpotStreamV2(endpoints.indexer)

const streamManager = new StreamManagerV2({
  id: 'spot-trades',
  streamFactory: () => stream.streamTrades({
    marketIds: ['0x...'], // オプション
    subaccountId: '0x...', // オプション
    direction: TradeDirection.Buy, // オプション
    callback: (response) => {
      streamManager.emit('data', response)
    }
  }),
  onData: (trades) => {
    console.log(trades)
  },
  retryConfig: { enabled: true }
})

streamManager.on('connect', () => console.log('Stream connected'))
streamManager.start()
```
