i'm trying to load a list of wallpapers from local storage that i already post them and saved their paths in mongoDB.

So i'm trying to loop through the array of paths and use each path as src in each img tag

the main.js ponent :

import React, { Component } from 'react'

export default class Main extends Component {
    state = {
        data : []
    }
    ponentDidMount(){

        fetch('http://localhost:5000/').then(res => res.json())
        .then(data=> this.setState({data}))

    }
    render() {

        console.log(this.state.data)

        return (
            <div>
                <h1>Main</h1>
                {this.state.data ? this.state.data.map(img => 
(<div key={img._id}>{img ? <img src={require(`${img.img.path}`)} 
alt={img.img.name}/>:<span>deleted</span>}</div>)): 
<h3>loading</h3>}
            </div>
        )
    }
}

the server code :

  server.get('/', (req, res)=>{
        Wallpaper.find({}, (err, result)=>{
            if(err) {
                res.json({msg: err})
            }else{
                res.json(result)
            }
        })
    })

it should return the images in the uploads folder in the react app but it returns this error:

Error: Cannot find module '/home/ahdy/Workspace/Wally/wallcraft/public/uploads/ak47456193147469824_n.jpg'

• Why the require() call? If those images are in some folder on the server, just the src directly to their URL. – user5734311 Commented Jul 18, 2019 at 13:43
• this.state.data ? will be true anyways, use this.state.data.length ? – julian libor Commented Jul 18, 2019 at 13:59

This

<img src={require(`${img.img.path}`)}

should be

<img src={`/uploads/${img.img.path}`}

no need of require here

NB: put correct path there
