Execute thunks in parallel with concurrency support and gather all the results
npm install co-gatherco-gather
=========
Execute thunks, generators, async functions in parallel with concurrency support and gather all the results.
co-gather is similar with co-parallel, but co-gather will gather all the result of these thunks, even those thunks throw error.
``
$ npm install co-gather
`js
const gather = require('./');
const sleep = require('mz-modules/sleep');
function* gfun(result, error, interval) {
yield sleep(interval || 100);
if (error) throw new Error(error);
return result;
}
async function afun(result, error, interval) {
await sleep(interval || 100);
if (error) throw new Error(error);
return result;
}
console.time('gather');
gather([
gfun(1),
gfun(null, 'error'),
async () => afun(null, 'error'),
() => afun(4),
], 2).then(res => {
console.timeEnd('gather');
console.log(res);
});
