Async: v3.0 and eachSeries async/await

[endbay]

Hey,

v3.0 doesn't bring async/await support for eachSeries yet? Is there a full list, which async functions now support Promise?

Expected with this update:

async.eachSeries(items, async (item, callback) => {
            const itemStats = await someFunc(item);
           callback();
});

Currently in usage:

async.eachSeries(items, (item, callback) => {
         (async () => {
            const itemStats = await someFunc(item);
            callback();
          })();
});

Async doesn't pass callbacks to async functions. Simply return!

async.eachSeries(items, async (item) => {
            const itemStats = await someFunc(item);
});

Sorry, my question wasn't that good.

Without callback() i'm not able to handle the error after:

async.eachSeries(items, async (item) => {
            const itemStats = await someFunc(item);

            if(!itemStats) throw new Error('no stats found');

}, (err) => {
       if(err) return res.status(500);

       return res.status(200).json({success: true})
});

This won't work without callback or?

The idiomatic way to handle this with async/await would be:

try {
    await async.eachSeries(items, async (item) => {
            const itemStats = await someFunc(item);

            if(!itemStats) throw new Error('no stats found');
    })
} catch (err)  {
   return res.status(500);
}
return res.status(200).json({success: true})
