# Uniswap-info 范例

在部署好subgraph，同步好数据之后，就需要修改前端代码来支持。

修改的地方有几处：

1、src/constants/index.js 

`export const FACTORY_ADDRESS = '0xb0f0a809b898b91db7d862819dbff83d3539bf82'`

2、src/apollo/client.js

子图查询代码：

`export const client = new ApolloClient({ link: new HttpLink({ uri: 'https://q.hg.network/subgraphs/name/rrex/heco', }), cache: new InMemoryCache(), shouldBatch: true, })`

健康检查：

`export const healthClient = new ApolloClient({ link: new HttpLink({ uri: 'https://h.hg.network/graphql', }), cache: new InMemoryCache(), shouldBatch: true, })`

区块信息：

`export const blockClient = new ApolloClient({ link: new HttpLink({ uri: 'https://q.hg.network/subgraphs/name/kdex-heco-blocks', }), cache: new InMemoryCache(), })`
