Support promises in async version
See original GitHub issueIssue Description
Hey! Great library!
I am using it in the browser, and it would be great if the async versions would support promises as well instead of just callbacks.
Ideally it would look something like this:
const buffer = await fflate.zip(
{
'index.html': fflate.strToU8(str),
// other files...
},
{ level: 4 }
);
It looks like synchronous code but it doesn’t block the main thread.
It makes sense to support promises, newer versions of node are doing so with stuff like fs/promises and timers/promises

I have thought of using a separate build for IE11. I write ESNext for all of my personal projects and make heavy use of
Promise; usually I don’t try to support IE11 as it’s a dead browser, but when I do I use the polyfill you linked forPromise. The problem for a project like this is that the entire package is designed to be lower-level and to support ancient engines, so adding one component of new JS is incongruous. Check out #75, in whichfflateneeded to support another rare engine, V4: if there’s a special bug withPromisein V4, as there was for typed arrays, I’d have to commit to supporting it. I’ve also been asked to add support for WHATWG streams in the streaming APIs, but those are even more recent and even more unsupported thanPromise. Basically, the fewer modern featuresfflateuses, the more maintainable it is for me and the more compatible it is for every user.As support for features of new JS is such a popular feature request, I’ll create a wrapper for
fflatethat supports the modern features you want. See #80 for more info.Future users can just search the issues tab for “Promise” and they’ll find it. Thanks for the feature request!
