How to unzip from a file upload?

[steve]

Hi

I have not found an example on your github README how to unzip a file and assumed I could do it with the same logic as a url.

This is my example:
https://codesandbox.io/s/hardcore-frog-ptq1q6?file=/src/index.js

I zipped up a json file like this:
{
"myjson": {
"result": [
"1",
"3",
10
],
"x": true
}
}
Then uploaded via a file, but when running your code I get

zip: Object
comment: ""
commentBytes: Uint8Array
entries: Object
file.json: ZipEntry
_reader: BlobReader
blob: File
<constructor>: "BlobReader"
_rawEntry: Object

How do I unzip it?

You get a list of files in the zip file like this

  const {entries} = await unzip(file);

To list all the files

   console.log(Object.keys(entries).join('\n'));

entries is just a JavaScript object with name entry pairs. If your zip file had

somedata.json
notes.txt
image.jpg
elephant.glb

Inside then entries would be

{
  'somedata.json': entry,
  'notes.txt': entry,
  'image.png': entry,
  'elephant.glb': entry,
}

You can get the contents of any one of them like this

    const someData = await entries['somedata.json'].json();
    const notes = await entries['notes.txt'].text();
    const blob = await entries['image.png'].blob();
    const glb = await entries['elephant.glb'].arrayBuffer();

That's it:
I've updated the codesandbox for reference.
