Javascript create zip file

I am developing a website using react.js and admin-on-rest. One feature is allowing users to upload a pdf file.

I get the file as type FILE and want to get the file from FILE, compress it to zip, and then make it to type FILE.

So it should be FILE -> origin file -> zip file -> FILE from zip file.

I tried JSZip but still can not figure it out.

Any help is appreciated. Thanks

Hi Garrick following are the steps you need to take.

1) handle fileupload in a rest wrapper https://marmelab.com/admin-on-rest/RestClients.html#decorating-your-rest-client-example-of-file-upload

the above example is for image upload. But you will essentially be doing the same thing.

2)

const addUploadCapabilities = requestHandler => (type, resource, params) => {
    if (type === 'UPDATE' && resource === 'posts') {
       //use jszip to zip file here and package it however you need
       // call the API with zipped file
   } return requestHandler(type, resource, params);
};
