Example code snippets to stream from the indexer for spot market module related data.

Using gRPC Stream

• stream the spot orderbook

import { IndexerGrpcSpotStream } from "@injectivelabs/sdk-ts";
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const indexerGrpcSpotStream = new IndexerGrpcSpotStream(endpoints.indexer);

const marketIds = ["0x..."];

const streamFn = indexerGrpcSpotStream.streamSpotOrderbookV2.bind(
  indexerGrpcSpotStream
);

const callback = (orderbooks) => {
  console.log(orderbooks);
};

const streamFnArgs = {
  marketIds,
  callback,
};

streamFn(streamFnArgs);

• stream spot orders

import { IndexerGrpcSpotsStream } from "@injectivelabs/sdk-ts";
import { OrderSide } from "@injectivelabs/ts-types";
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const indexerGrpcSpotStream = new IndexerGrpcSpotsStream(endpoints.indexer);

const marketId = "0x...";
const subaccountId = "0x..."; /* optional param */
const orderSide = OrderSide.Buy; /* optional param */

const streamFn = indexerGrpcSpotStream.streamSpotOrders.bind(
  indexerGrpcSpotStream
);

const callback = (orders) => {
  console.log(orders);
};

const streamFnArgs = {
  marketId,
  subaccountId,
  orderside,
  callback,
};

streamFn(streamFnArgs);

• stream spot order history

import {
  TradeDirection,
  TradeExecutionType,
  IndexerGrpcSpotStream,
} from "@injectivelabs/sdk-ts";
import { OrderSide } from "@injectivelabs/ts-types";
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const indexerGrpcSpotStream = new IndexerGrpcSpotStream(endpoints.indexer);

const marketId = "0x..."; /* optional param */
const subaccountId = "0x..."; /* optional param */
const orderTypes = [OrderSide.Buy]; /* optional param */
const executionTypes = [TradeExecutionType.Market]; /* optional param */
const direction = TradeDirection.Buy; /* optional param*/

const streamFn = indexerGrpcSpotStream.streamSpotOrderHistory.bind(
  indexerGrpcSpotStream
);

const callback = (orderHistory) => {
  console.log(orderHistory);
};

const streamFnArgs = {
  marketId,
  subaccountId,
  orderTypes,
  executionTypes,
  direction,
  callback,
};

streamFn(streamFnArgs);

• stream spot trades

import {
  PaginationOption,
  TradeDirection,
  IndexerGrpcSpotStream
} from '@injectivelabs/sdk-ts'
import { getNetworkEndpoints, Network } from '@injectivelabs/networks'

const endpoints = getNetworkEndpoints(Network.TestnetK8s)
const indexerGrpcSpotStream = new IndexerGrpcSpotStream(endpoints.indexer)

const marketIds = ['0x...'] /* optional param */
const subaccountId = '0x...' /* optional param */
const direction = TradeDirection.Buy /* optional param */
const pagination = {...} as PaginationOption /* optional param */

const streamFn = indexerGrpcSpotStream.streamSpotTrades.bind(indexerGrpcSpotStream)

const callback = (trades) => {
  console.log(trades)
}

const streamFnArgs = {
  marketIds,
  subaccountId,
  orderTypes,
  direction,
  pagination,
  callback
}

streamFn(streamFnArgs)

• stream markets

import { IndexerGrpcSpotStream } from "@injectivelabs/sdk-ts";
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const indexerGrpcSpotStream = new IndexerGrpcSpotStream(endpoints.indexer);

const marketIds = ["0x..."]; /* optional param */

const streamFn = indexerGrpcSpotStream.streamSpotMarket.bind(
  indexerGrpcSpotStream
);

const callback = (markets) => {
  console.log(markets);
};

const streamFnArgs = {
  marketIds,
  callback,
};

streamFn(streamFnArgs);

• stream orderbook updates

import { IndexerGrpcSpotStream } from "@injectivelabs/sdk-ts";
import { getNetworkEndpoints, Network } from "@injectivelabs/networks";

const endpoints = getNetworkEndpoints(Network.TestnetK8s);
const indexerGrpcSpotStream = new IndexerGrpcSpotStream(endpoints.indexer);

const marketIds = ["0x..."];

const streamFn = indexerGrpcSpotStream.streamDerivativeOrderbookUpdate.bind(
  indexerGrpcSpotStream
);

const callback = (orderbookUpdates) => {
  console.log(orderbookUpdates);
};

const streamFnArgs = {
  marketIds,
  callback,
};

streamFn(streamFnArgs);
