Introduction to HTML5 Desktop Apps With Node-Webkit

Introduction to HTML5 Desktop Apps With Node-Webkit | JavaScript for Line of Business Applications | Scoop.it
From www.lexiqueinformatique.fr - October 6, 2014 2:32 PM

The library combines WebKit engine and Node.js in a unique way. Both WebKit and Node share the same context, allowing you to write your code like it’s meant to be executed in a browser, but with the addition of all Node’s features.

The list of uses is endless. You can create business apps, text and image editors, games, presentations, admin panels, etc. Just name the desktop app that you would like to create, and I can assure you that it will be possible with node-webkit.


In this tutorial, I will show you how to get started by showing you how to create a simple text editor.

Explorations In Automatically Fixing JavaScript Linting-errors

Explorations In Automatically Fixing JavaScript Linting-errors | JavaScript for Line of Business Applications | Scoop.it
From addyosmani.com - October 2, 2014 3:51 AM

FixMyJS (by Josh Perez) was created to try solving this problem. It aims to automatically fix linting errors in a non-destructive way. To an extent, it achieves this goal.

Under the hood the module uses Esprima for source parsing and Escodegen (from the Mozilla Parser API AST) to generate it back. While any form of automation code transformation should be approached with a healthy dose of skepticism, FixMyJS is able to handle fixing basic JSHint errors fairly well. Some of what it supports includes:

  • Adding missing semicolons
  • Enforcing camelCase and snake_case conventions
  • Adding curly braces to statements
  • Removing debugger statements
  • Enforcing single and double quite styles
  • Adding the radix parameter to parseInt
  • Dot notation conversion
  • Handling extra trailing commas

and a few other common linting issues.

How to optimize your Mongo database for Meteor.js

How to optimize your Mongo database for Meteor.js | JavaScript for Line of Business Applications | Scoop.it
From joshowens.me - October 1, 2014 4:12 PM

Kadira. The amount of insight and analytics you get from Kadira is worth every penny, especially when you are trying to optimize for production. Once I installed and deployed the app with Kadira in it, the app started sending back the metrics from the running meteor app.

As I've said before, publications are the life blood of your meteor app. I started by going to the Pub/Sub detailed tab in Kadira and switched to sort by response time. I quickly noticed that one publication had the second highest subscribe rate and an average response time of 2171ms - that signaled a pretty big bottleneck for me.

How to scale a meteor.js app

How to scale a meteor.js app | JavaScript for Line of Business Applications | Scoop.it
From joshowens.me - October 1, 2014 4:08 PM

Meteor is a little different than traditional 'static html' frameworks. The Meteor platform uses things like web sockets, DDP, and a pub/sub model to get data in the right spot. That means we can't just throw varnish in front of an app and get our 'magic scaling beans'.

Tips and Tricks for Faster Front-End Builds

Tips and Tricks for Faster Front-End Builds | JavaScript for Line of Business Applications | Scoop.it
From io.pellucid.com - September 29, 2014 6:16 PM

As a reduced test case for experimentation, I set up a sample repository. The project uses jQuery, Lo-dash, and Handlebars, along with 50-or-so custom CommonJS modules (bundling to half a megabyte) to give Browserify something to work with.

In this repository, our ideal build system will do the following (doubly ideal would be doing these things quickly... we'll get there).

  • Preprocess, prefix, and minify CSS
  • Lint/Hint, Browserify, and Uglify our JavaScript
  • Watch for changes and re-run any appropriate steps

Our build process at Pellucid has a few more requirements than this, but these should cover some of the longest operations, and this sample project should be generic enough to apply to many front-end projects.

Using ServiceWorker in Chrome today

Using ServiceWorker in Chrome today | JavaScript for Line of Business Applications | Scoop.it
From jakearchibald.com - September 29, 2014 11:38 AM

ServiceWorker is a background worker, it gives us a JavaScript context to add features such as push messaging, background sync, geofencing and network control.

In terms of network control, it acts like a proxy server sitting on the client, you get to decide what to do on a request-by-request basis. You can use this to make stuff work faster, offline, or build new features.

I'm biased, but I think ServiceWorker changes the scope of the web more than any feature since XHR.

Testing Flux Applications

Testing Flux Applications | JavaScript for Line of Business Applications | Scoop.it
From facebook.github.io - September 26, 2014 12:24 PM

For a unit test to operate on a truly isolated unit of the application, we need to mock every module except the one we are testing. Jest makes the mocking of other parts of a Flux application trivial.

Javascript promises and why jQuery implementation is broken

Javascript promises and why jQuery implementation is broken | JavaScript for Line of Business Applications | Scoop.it
From thewayofcode.wordpress.com - September 26, 2014 4:48 PM

It’s very easy to find blog articles and tutorials online, especially around jQuery Deferred object, and almost all of them show how to do callback aggregation using the “then”function to attach callbacks to a promise, whether for success or for errors (or even to signal that an operation has made some progress). When the promise transitions state, the callbacks will be called, that’s as simple as that.

Bringing Sanity to JavaScript UTC Dates with Moment.js and Ember Data

Bringing Sanity to JavaScript UTC Dates with Moment.js and Ember Data | JavaScript for Line of Business Applications | Scoop.it
From blog.skylight.io - September 25, 2014 2:03 PM

One "neat" (awful) feature in JavaScript is that it automatically changes dates to be in whatever timezone the user's computer is set to.

This is great if you are building the online version of The Podunk Gazette and all your servers and users are in one town. Otherwise, it can introduce small inconsistencies between clients and your backend servers.

From scottksmith.com - October 6, 2014 2:00 PM

Using Favatron as a guide, I will take you through the entire process of creating a fully functional production ready Node web application. Some of the many parts we will touch on include authorization, user accounts, data storage, background workers, security, email, APIs, RSS, third party service integrations, and much more.

I am proud to introduce Twitatron, the web application we will be making. Twitatron will automatically monitor your Twitter account for mentions. When it finds those mentions, it will process them, store them, show them in the UI, expose them via an API endpoint and RSS feed, send an email digest, and share weekly stats with integrated social networks.

In this post, I will review some scenarios that often contribute to memory leaks and discuss the APIs in Knockout that can be used to prevent and resolve these issues.

From joshowens.me - October 1, 2014 4:06 PM

From a high level, Meteor.js gives you four folders that are treated special by the build tool: client, public, server, and test. Anything not in those special folders will be compiled by the build tool and sent to both the client and the server. This is where guidance from the Meteor Development Group stops.

Reactive Modeling with Ember

Reactive Modeling with Ember | JavaScript for Line of Business Applications | Scoop.it
From frontside.io - October 1, 2014 2:33 PM

The ideas behind reactive modeling are universal. After all, they underpin the MVC pattern which is, at this point, older than many Javsascript developers. Reactive modeling can be applied inside whatever runtime environment you happen to find yourself. However, it is my experience that when working on the web, the reactive primitives provided by Ember.js are the most intuitive and expressive to be found in a mainstream framework, and so all of the following examples are written with it.
