QUESTION

Unable to download pdf in react application on host

Asked 2022-Mar-03 at 14:52

Download PDF-File won't work on AWS-Host.

import React, {Component} from 'react';
import aa from "../media/AA.pdf";

export default class FileDownloader extends Component {
    render() {
        return (
            <div className="pdf">
                <a href={aa} download="aa.pdf">Download</a>
            </div>
        );
    }
}

I tried with different method <a href={process.env.PUBLIC_URL + "/media/AA.pdf"} download="AA.pdf">Download</a> but same error

The media Folder is into app/src/media/aa.pdf

local it works fine by on the AWS host i can't download the file. The Browser tries to download but doesn't save. I use AWS Amplify

ANSWER

Answered 2022-Mar-03 at 14:52

The problem was the Rewrites and redirects in AWS.

Add in a new rule or change existing rule |pdf|

  • Source should be </^[^.]+$|\.(?!(css|pdf|gif|ico|jpg|js|png|txt|svg|woff|ttf|map|json)$)([^.]+$)/>
  • Target address index.html
  • Type 200 (Rewrite)
