   api.get("/api/getallitems").then(
       response => {
           console.log(response.data)
           this.setState({
               data: response.data
           })
       }
    )

    const {data} = this.state;
    return(
        <div>
        {
            data.length ?
            data.map(
            info => {

This is how you need to do it:

render(){
    const {data} = this.state;
    return(
        <div>
        {
            data.length ?
            data.map(
            info => {
    return(
            <div>
                <h2 key={info.id}>{info.id, info.name, info.stock}</h2><br/>
                <script scr={console.log(info)}/>
            </div>)
            }):null
         }
         this is data from api
         </div>
    );
  }
