    AsyncArray

    Yet another control flow library after getting fustrated with previous ones.

    Usage

    The next callback takes the arguments (error, data)

    var AsyncArray = require('async-array')
    
    var array = new AsyncArray([1, 2, 3, 4])
    
    array
      .map(function (item, i, next) {
        db.query('SELECT * FROM x WHERE id = ?', [item], next)
      })
      .done(function (error, results) {
        console.log("Got me database listings partner!")
      })
      .forEach(function (db_result, i, next) {
        doSomethingAsync(db_result, next)
      })
      .exec()
    

    As you can see, you can chain stuff and the result is passed along from the previous operation. If you don't call exec immediately you can store the operation to be executed at some later time.

    AsyncArray inherits from Array with the following methods added:

    • map
    • mapSerial
    • filter
    • filterSerial
    • forEach
    • forEachSerial

    Serial methods do things one after another instead of in parallel.
