// `done` is a callback that you fire manually when you function is done executing.
run.before(function(data, done){
    data.foo = 'bar';
 
    asyncOp(function(err, data){
        done(err);
    });
}, function(data, done){
    data = syncOp(data);
    done();
});

    db.update(query, data, function(err, data){
        data = data;

});
 
run.after(function(data, done){
    data = translateObj(data);

    console.log(data); // your data
});
 

API

Runn

Constructor, returns a fresh instance.

.before, .middle, .after

Accepts any number of named or anonymous functions as arguments. Runn will run these functions in series.

.exec

Accepts an Object and a callback.

When .exec is called, the functions passed into .before, .middle and .after will be executed in order, passing the first argument of the .exec method in each time.
