• Simulating Network Latency In AngularJS With $http Interceptors And $timeout

  Posted on Mar 17, 2015 at 9:08 AM

  If you can, you can simulate delays or server responses using ServiceWorker without requiring application code modifications https://github.com/bahmutov/ng-wedge Pretty advanced but might come in handy... read more »

• Creating Objects With A Null Prototype In Node.js

  As it happens sometimes, I have looked at the "naked" objects too, see http://glebbahmutov.com/blog/sweet-naked-objects/.... read more »

• Monkey-Patching The $q Service Using $provide.decorator() In AngularJS

  Posted on Feb 9, 2015 at 4:27 PM

  @Ward, maybe one could make Q to behave synchronously for the purpose of the unit test. For example I made q-flush for Node (could be extended to browser I guess), https://github.com/bahmutov/q-flush It adds `Q.deferFlush()` and `Q.flush()` methods that can do things like <pre> var result... read more »

  I described why it is important to start the promises right (and handle any errors via promise mechanism) http://bahmutov.calepin.co/starting-promises.html... read more »

  Posted on Jan 31, 2015 at 6:57 PM

  Ben, you can release it as a stand alone library by cloning my https://github.com/bahmutov/angular-q-timeout using decorator repo (includes unit tests too), and putting your code in.... read more »

  Ben, It would be nice to have this patch as a stand alone bower / npm module, because I want to use it.... read more »

  Posted on Jan 30, 2015 at 9:57 AM

  Ben, For your demos - just include https://github.com/bahmutov/console-log-div script on your page (you can even do this through https://rawgit.com/bahmutov/console-log-div/master/console-log-div.js ) to mirror console.log and console.error calls onto the page. Then you don't need to open browser... read more »

• Handling Top-Level Errors In A Promise Workflow In AngularJS

  Posted on Jan 29, 2015 at 9:19 AM

  @Gleb, Sorry, the code got abridged in the above comment var S = require('spots'); // _to does NOT return a promise function _to(folderName) { } // exports a method to that returns a promise and catches any error in _to module.exports = { to: S(q.try, _to, S) };... read more »

• Handling Top-Level Errors In A Promise Workflow In AngularJS

  Posted on Jan 29, 2015 at 9:17 AM

  It is important to wrap the initial call and catch any errors there and direct them into `.catch` callback. There is Q.fcall, I prefer to use an alias to it `Q.try ` https://github.com/kriskowal/q/wiki/API-Reference#promisefcallargs I usually start my promise chains (I should write a blog po... read more »

• Exploring Asynchronous Promise-Based Workflows In AngularJS

  Posted on Jan 28, 2015 at 8:45 AM

  Good points, understanding how the rejected promise gets handled by the first catch function but then becomes good again is very important. I call these promise paths, but overall the idea is the same http://bahmutov.calepin.co/promise-paths.html... read more »

• Directive Controllers Can Use Dependency Injection In AngularJS

  Posted on Dec 5, 2014 at 9:02 AM

  @Jorge, I prefer custom directives with isolate scopes - makes each part of the page pretty well defined and simple to understand since there is less coupling. As far as testing / performance: we try to keep number of things a directive needs to minimum (number of injected dependencies + scope prope... read more »

• Creating And Extending A Lodash / Underscore Service In AngularJS

  Posted on Nov 18, 2014 at 10:30 AM

  @Ben Yup, the $provider allows you to add new stuff to the injector (this is what gets called when you do angular.module().value or angular.module().factory). I use it to add new stuff to the injector at run time.... read more »

• Creating And Extending A Lodash / Underscore Service In AngularJS

  Posted on Nov 18, 2014 at 10:19 AM

  @Ben I liked your example so much, I wrote ng-wrap https://github.com/bahmutov/ng-wrap that can wrap arbitrary global (and optionally remove it) to make it available as a dependency. <pre> angular.module('App', ['ng-wrap']) .run(function (ngWrap) { ngWrap('_'); // or t... read more »

• Creating And Extending A Lodash / Underscore Service In AngularJS

  Posted on Nov 18, 2014 at 8:52 AM

  Cool, good observation on `.run` to make sure this factory always happens. Also, good decision on deleting from window scope to make sure people do not use _ directly. You could also extend lodash using their own built-in method mixin.... read more »

• Directive Controllers Can Use Dependency Injection In AngularJS

  Posted on Nov 3, 2014 at 8:58 AM

  Wouldn't it be better to DI the directive function explicitly? ``` app.directive('myFoo', ['myController', function (myController) { return { restrict: 'E', controller: myController }; }]); ```... read more »

  I included a code snippet based on ng-snippets to count number of watchers for both normal and isolate scopes in my collection of code snippets https://github.com/bahmutov/code-snippets Use them in Chrome DevTools code snippets like this: http://bahmutov.calepin.co/chrome-devtools-code-snippets.ht... read more »
