Description
Update: Changed subject to reflect the current focus.
I tried out the example at https://github.com/getify/asynquence/blob/master/contrib/README.md#errfcb-plugin that talks about sq.errfcb() plugin. When I execute the code, the parameter passed to .then() doesn't seem to have the desired data. (That's the data which would have been passed as the second parameter of the error-first callback). How is it made available?
// first install with "npm install asynquence"
var ASQ = require("asynquence-contrib");
fs = require("fs");
// Node.js: fs.readFile(..) wrapper
function readFile(filename) {
// setup an empty sequence (much like an empty
// promise)
var sq = ASQ();
// call Node.js' `fs.readFile(..), but pass in
// an error-first callback that is automatically
// wired into a sequence
fs.readFile( filename, 'utf8', sq.errfcb() );
// now, return our sequence/promise
return sq;
}
readFile("/Users/richb/meaningoflife.txt")
.then((data) =>
{ console.log("Read fine...", data) })
.or((err) =>
{ console.log("Error", err) })
Update: added 'utf8' parameter to fs.readFile() so that resulting data is a string, not a buffer.
