Yeah... this is going to need some testing considering the huge version bump

I fiddled with this a bit today but couldn't get it working. Pako 2.0.0 drops support for binary string inputs which requires us to stuff the binary data into an Uint8Array first, which I can do, but I wasn't able to get it to output a deflated format that the current version of Toolbox can still read, so it seems there's something else going on here.

For future Erin's benefit:

// Get Uint8Array from binary string
const bytes = Uint8Array.from(binaryString, c => c.charCodeAt(0));
// Get binary string from Uint8Array
const binaryString = bytes.reduce((data, byte) => data + String.fromCharCode(byte));
// (remember, binary strings are not base64 strings)

Okay so I'm kind of an idiot but it looks like modifying zlibInflate a bit should work?

atob outputs a string, which can then be split at the commas to get an array, which is then fed to a new Uint8Array, which can then be inflated properly; the inflated output is identical to the stringified JSON.

If I am missing something, hopefully this is at least helpful to get you further along!

Okay so I was an idiot... but this time I swear I'm not; here's the patched functions to return identical output under pako 2.0.4 as 0.2.6; attached is a gist you can use to double check my work.

function zlibInflate (stringThing) {
    // Expand base64
    var zlibBinData = atob(stringThing);
    
    //binary to Uint8Array
    var zlibCharData = zlibBinData.split('').map(function (e) {
        return e.charCodeAt(0);
    });
    var binData = new Uint8Array(zlibCharData);
    
    // zlib time!
    var data = pako.inflate(binData);
    return String.fromCharCode.apply(null, new Uint16Array(data));
}
    
function zlibDeflate (objThing) {
    // zlib time!
    var zlibString = pako.deflate(jsonString, { to: 'string' });
    //convert Uint8Array to String
    zlibString = String.fromCharCode.apply(null, new Uint16Array(zlibString));
    return btoa(zlibString)
}
