Meteor Wrapasync !new! < Windows POPULAR >

Meteor 3 has removed Fibers. wrapAsync still works, but you should migrate to native async/await :

const readFileSync = Meteor.wrapAsync(fs.readFile); const content = readFileSync('/path/to/file', 'utf8'); But remember: in Meteor 3, just use fs.promises.readFile with await . Progress! ⚡ meteor wrapasync

import { Meteor } from 'meteor/meteor'; Meteor.methods({ 'getData'(id) { const syncGetData = Meteor.wrapAsync(legacyLibrary.getData); return syncGetData(id); } }); Meteor 3 has removed Fibers

It converts a callback-based asynchronous function into a synchronous-looking one (using Fibers under the hood in Meteor 2.x and below). const content = readFileSync('/path/to/file'

Need to use an old-school callback function in Meteor? wrapAsync has your back.
