Example
'use strict';
// instead of this:
app.get('/renamefoo', function (req, res, next) {
FooModel.findOne({ name: req.query.oldname }, function (err, oldfoo) {
if (err) {
next(err);
} else {
oldfoo.name = req.query.newname;
oldfoo.save(function (err, newfoo) {
if (err) {
next(err);
} else {
res.json(newfoo);
}
});
}
});
};
// you can write this:
app.get('/renamefoo', function (req, res, next) {
FooModel.findOne({ name: req.query.oldname }, errcb(next, function (oldfoo) {
oldfoo.name = req.query.newname;
oldfoo.save(errcb(next, function (newfoo) {
res.json(newfoo);
});
}));
});
// or this:
app.get('/renamefoo', function (req, res, next) {
var myerrcb = errcb.bind(null, next);
FooModel.findOne({ name: req.query.oldname }, myerrcb(function (oldfoo) {
oldfoo.name = req.query.newname;
oldfoo.save(myerrcb(function (newfoo) {
res.json(newfoo);
}));
}));
});
