I got it working with a few changes:

var mongoskin = require('mongoskin'),
dbHost = '127.0.0.1',
dbPort = 27017;

var db = mongoskin.db('mongodb://' + dbHost + ':' + dbPort + '/local', {safe: true});

db.bind('messages').bind({
findOneAndAddText: function (text, fn) {
db.collection('messages').findOne({}, function (error, item) {
if (error) {
console.error(error);
process.exit(1);
}
console.info("findOne: ", item);
item.text = text;
var id = item._id.toString(); // we can store ID in a string
console.info("before saving: ", item);
db.collection('messages').save(item, function (error, count) {
console.info("save: ", count);
return fn(count, id);
});
})
}
});

db.messages.findOneAndAddText('hi', function (count, id) {
db.collection('messages').find({
_id: mongoskin.helper.toObjectID(id)
}).toArray(function (error, items) {
console.info("find: ", items);
db.close();
process.exit(0);
});
});

@nikolaygit @josevillacreses yes. mongoskin changed the way methods are created. bind().bind() will work. I updated it in new edition's code https://github.com/azat-co/practicalnode/blob/master/code/ch5/mongo-examples/mongo-skin.js

@pkwenda maybe mongodb (npm module) version? check the new code at https://github.com/azat-co/practicalnode/blob/master/code/ch5/mongo-examples/mongo-native-insert.js after you install proper versions with npm i
