有人能帮我吗

import*作为来自“React”的React
从“react”导入{Component}
从'react apollo'导入{graphql}
从“graphql标记”导入gql
从“/LinkList”导入{FEED_QUERY}
从“../constants”导入{LINKS\u PER\u PAGE}
类CreateLink扩展组件{

等待这个。道具。后置换({
变量:{
描述
网址,
},
更新:(存储,{data:{post}})=>{
const first=每页链接数
常数跳过=0
const orderBy='createdAt_DESC'
const data=store.readQuery({
查询:FEED_查询,
变量:{first,skip,orderBy},
})
数据。馈送。链接。拼接(0,0,post)
data.feed.links.pop()
store.writeQuery({
查询:FEED_查询,
数据,
变量:{first,skip,orderBy},
})
},
})
this.props.history.push(`/new/1`)
}
}
// 1
常量后突变=gql`
# 2
突变后突变($description:String!,$url:String!){
帖子(描述:$description,url:$url){
身份证件
创建数据
网址
描述
}
}
`
// 3
导出默认图形ql(POST_突变,{name:'postMutation'})(CreateLink)
您尚未为道具创建类型。typescript编译器抛出错误,因为它认为您定义的方法不存在。下面是一个类型化react组件的示例
type AppProps = { // like this
message: string,
}
type AppState = { // and this
count: number,
}
class App extends React.Component<AppProps, AppState> {
state = {
count: 0
}
render() {
return (
<div>{this.props.message} {this.state.count}</div>
);
}
}
键入AppProps={//,如下所示
消息:string,
}
输入AppState={//,然后
计数:数字,
}
类应用程序扩展了React.Component{
状态={
计数:0
}
render(){
返回(
{this.props.message}{this.state.count}
);
}
}
