• advisable

    Advisable is a JavaScript library for Node and the browser providing functional mixins for both async and sync aspect-oriented advice.

    // advisable-example.js
    var advisable = require('advisable');
    var arithmetic = {
      add: function (x, y) {
        return x + y;
    var logBefore = function (x, y) {
      console.log('before, args => x: %d, y: %d', x, y);
    var logAfter = function (x, y) {
      console.log('after, args => x: %d, y: %d', x, y);
    // Mix in advice behavior;
    // Demonstrate before and after logging with around advice
    arithmetic.aroundSync('add', logBefore, logAfter);
    // Perform the addition
    z = arithmetic.add(2, 3);

    Running the script shows the logging advice:

    ➜ node advisable-example.js
    before, args => x: 2, y: 3
    after, args => x: 2, y: 3

  • invoke

    Invoke is my take on async JavaScript control flow for Node and the browser.

    // Given an async db api:
    //   db.find(id, callback)
    // And an async data aggregation function
    //   aggregate(x, y, z, callback);
    var invoke = require('invoke')
      , db = require('db')
      , aggregate = require('aggregate');
    // Fetch three records in parallel, then aggregate
    invoke(function (initial, callback) {
      db.find('id-0', callback);
    }).and(function (initial, callback) {
      db.find('id-1', callback);
    }).and(function (initial, callback) {
      db.find('id-2', callback);
    }).then(function (results, callback) {
      aggregate(results[0], results[1], results[2], callback);
    }).rescue(function (err) {
       // Handle any errors by logging to console
    }).end(null /* initial data */, function (result) {
      // Log result
      console.log('result: %d', result);
