javascript

Todd Gardner of TrackJS will be at Hypoport THIS Thursday Sep. 24th. Abstract Something terrible happened here. Traces of errors litter the floor; memory leaking from cracks in the ceiling. Someone lost their object context in the corner. Everything reeks of jank. In this session, a JavaScript error tracking expert breaks down a series of common and complex crimes against web applications. You’ll leave the session armed with techniques and tools to detect, diagnose, and fix your JavaScript web applications.

On Wednesday Feb 11, the evening before microxchg – the micro services conference, Hypoport is hosting the microservices meetup Berlin with talks from two of the conference speakers. Richard Roger will talk about Seneca Node JS μServices Framework Peter Rossbach will talk about Docker Orchestration Please register on microservices meetup Berlin. See you there, Leif

I recently built a custom directive that needed to call a function in its parent scope and pass some interal variables back as arguments. To be more specific: an editable label – a simple text that turns into an input field when it’s clicked and turns back into plain text, when the focus leaves the input field. On top of that, I needed it to invoke a callback function, if – and only if – the value of the input field has actually been changed.

Yesterday I spent the entire day trying to narrow down a nasty CSS bug that only surfaced in Internet Explorer 8. Everyones favourite browser didn’t redraw a pseudo element created via :before when its style got changed by adding or removing a class via JavaScript. It was a custom checkbox element with a JavaScript click handler that simply toggled a class on every click. Getting to the bottom of it Here is a jsFiddle with a trimmed down version of said checkbox.

Written by Andreas Marek (@andimarek). We (the team I work in) are developing an AngularJS application for the last several months. Most of our customers are still using IE 8, so we need to support that browser. Our app is using AngularJS 1.1.5 and jQuery 1.x. A few weeks ago it was time to make our app work in IE 8. A good starting point is the official Angular IE guide.

Im Rahmen der Entwicklung eines unserer Frontends verwenden wir node.js. Node.js erlaubt Paketmanagement mit Hilfe des Node Package Managers (NPM), der ähnlich wie Maven eine global verfügbare Registry verwendet. Einrichten einer lokalen NPM-Registry Die NPM-Registry wird auf einem nicht immer stabil erreichbarem Host bereitgestellt. Um die Latenz beim Abruf der aktuellen Paketinformationen zu vermeiden und um Downtimes möglichst gut kompensieren zu können, kann man einen Mirror der NPM-Registry im lokalen Netz bereitstellen.
