how to download file in react js

Question

I receive file url as response from api. when user clicks on download button, the file should be downloaded without opening file preview in a new tab. How to achieve this in

Answer 1

I have the exact same problem, and here is the solution I make use of now: (Note, this seems ideal to me because it keeps the files closely tied to the SinglePageApplication React app, that loads from Amazon S3. So, it's like storing on S3, and in an application, that knows where it is in S3, relatively speaking.

Steps

3 steps:

1. Make use of file saver in project: npmjs/package/file-saver (npm install file-saver or something)
2. Place the file in your project You say it's in the components folder. Well, chances are if you've got web-pack it's going to try and minify it.(someone please pinpoint what webpack would do with an asset file in components folder), and so I don't think it's what you'd want. So, I suggest to place the asset into the public folder, under a resource or an asset name. Webpack doesn't touch the public folder and index.html and your resources get copied over in production build as is, where you may refer them as shown in next step.
3. Refer to the file in your project Sample code:

   import FileSaver from 'file-saver';
   FileSaver.saveAs(
       process.env.PUBLIC_URL + "/resource/file.anyType",
       "fileNameYouWishCustomerToDownLoadAs.anyType");

Appendix

• I also try Link component of react-router react-router-docs/Link. The zip file would download, and somehow would unzip properly. Generally, links have blue color, to inherit parent color scheme, simply add a prop like: style={color: inherit} or simply assign a class of your CSS library like button button-primary or something if you're Bootstrappin'
