Mastering web-storm

I am big fan of sublime text, and I use it extensively. Then I came across WebStorm, I like it and I want to learn more about it, because any craftsman should know how to use his tools effectively.
So I was looking for some tutorial and videos on mastering web storm and I came across this excellent video by John Lindquist. I highly recommend that you watch the video.

I have also tried to summarise what’s there in the video, but I recommend that you watch the whole thing, but for those who cannot spare the time to watch the whole thing, here is the excerpt:

Code Inspect:

Webstorm offers a nice code inspector, and to inspect code, right click on any directory inside Webstorm and click inspect Code.
It will give you a list of the issues and warnings and improvements which you can make, and is kind of really useful when your are doing code reviews and stuff like that.

Autocomplete Shortcut: Whenever a small bulb appears in Web storm, it indicated that Webstorm has some suggestions, and you can hit alt+Enter to bring the menu which shows the suggestions.

Go back in time: Webstorm has a nice auto-save feature, you don’t have to manually save things in Webstorm, and when you have changed something and want to revert your change you can go back in time by: Right-click-> local history

Getting things from CDN: When using CDN in script tags and stylesheets src, Webstorm will show a warning, you can hit alt+Enter->Download locally, by doing that it will download the linked file and show autocomplete off that.

Fine tune suggestions: In Webstorm you can fine tune the settings about auto-complete, suggestions, warning and errors.
Click on the lower right hand side corner->on hector the inspector and fine tune the inspection

Keyboard shortcuts:

To learn about keyboard shortcuts, go to
Shorcut Foo


Cmd + Shift + A bring the action bar.
Select content, and press cmd+shit+a and select create live template.
And add variable by $name$ and $end$ to specify where the cursor ends.
Webstorm uses velocity template language.


Refactor this shortcut CMD+SHIFT+ALT+T
/+tab automatically generate the document
to pulling out variable.

Open up the file structure: can also be invoked by cmd+f12

To navigate project: cmd+shift+n, wildcard are also supported
s/a/*.js -> source/auto/ and all the javascript
cmd+alt+shift -> type the name of the method
and cmd+shift+i while doing this, will also show preview of the file, and cmd+shift+j while doing that will show documentation if available.

Version control:

Webstrom also has an integrated VCS manager, to bring the VCS Popup hit Ctrl+V.
Webstorm is also integrated with Github, you can easily import your github repos in Web-storm.

External tools:

To add external tools, go to Preference -> External tools and add details about the external tools you want to add, for e.g. Yeoman

File launchers:

If you create a coffee script file, it will ask you to add a watcher, and it will generate the corresponding js file, same if for sass etc.

Dead Simple Screen sharing (DSS) – Overview

Grab source on GitHub

Project site

Sometime ago a developed an open-source screen sharing application called as DeadSimpleScreenSharing which allows you to share your screen with anyone right from your browser.
It requires you to install an extension, when you click “Share your Screen” button on that extension, it will gives you a unique url which you can share with any number of people, and they can view your screen.
In this blog post I will give a brief overview on how this application works.

The Extension:

The DSS requires you to install an extension, a extension is required because there has to be some application running background which listens to tab changes and transmits this data to the server.
The extension uses the chrome extension api’s caputreVisibleTab() method get the visible tab and attaches mutationObservers and listen for DOM changes, when there is a change in the DOM, it transmits the data to the server via web sockets.

The Server:

The server is written in Javascript(node.js) and uses web sockets (, each session is namespace by unique id which is generate when the user presses the “Share your screen” button on the extension.
The server just receives the data and forwards it to all the connected clients in that namespace.

Get it working locally:

If you want to run DSS locally, you need to have:
1. Node.js installed
2. Install express using ‘npm install express’
3. Install run ‘npm install’
and follow along the video.

Share your entire screen using Chromecast

Google’s chrome cast allows you to bream content from your computer/phone to TV, and you can play youtube videos, music, etc. It allows also a really nice feature called as tab sharing, it allows you to share your Google chrome tab to the TV.
But it doesn’t allows you to share your whole screen, in the post I’ll explain how you can do that.

Things required

  1. Latest version of Google Chrome
  2. Chromecast
  3. Google Cast extension installed in google chrome


  1. Visit
  2. Click on “Capture your screen button”
  3. Click on Chromecast extension and share the current tab
  4. Minimise Google chrome and enjoy.

Now can see your screen, but you can also a white border which is not nice, and you can’t get a full screen, to get past that you need to do a bit of extra work.

Download the zip package and extract it’s contents, and install Node.JS if you don’t have already.
Then open terminal in mac or Command Prompt in windows and type “cd “ and drag and drop the “server” folder into the terminal window.

Then run “sudo node app.js” and visit https://localhost (Note:It’s https not http), Google Chrome will give you a warning, and you can safely ignore it, because the certificates which I have created for https to work are not verified by any recognised issuing authority.

You’ll now see your screen, now share this tab with chrome cast and minimise the Google chrome.

Executing tasks (functions) on specific dates in Node.js

Sometimes you want to execute task after certain interval, I am not talking about executing a task after every 5 minutes, but after certain days; say every Monday at 5pm more like corn jobs.

If you are looking for a library which allows you to execute arbitrary functions at specific dates, so you’re in luck because an awesome Node.js library called node-schedule allows you do just that.

Head over to Github repo, and read about it in detail and get started.

AngularJS + Underscore The ultimate web-development toolkit (2018)

Before starting my latest web-development project I was looking for some robust javascript frameworks that I could use.

I was familiar with AngularJS and I loved it, but it doesn’t have a lot of utility methods and I was looking for some solution to solve that problem.

So, I thought about using UnderscoreJS, which is a collection of utility methods with angularJS and I got myself a killer web development toolkit. In this blog post, I have summed up UnderscoreJS methods which I find useful. visit to view all the available methods.

Using Underscore with Angular:

Combining angular and underscore is pretty straightforward, just add import underscore in your index.html, then add it as a service.

And then we could inject it into our controllers.

Useful Underscore methods:

I have compiled a list of my favourite underscoreJS methods, you can always visit to view all the methods that are available in underscore.


This method is used to determine whether the specified value is undefined or not, I know you could always do typeof value === “undefined” to check whether it is undefined or not, but I find this neater.


This is also a very useful method, it allows you to define default values for something if they are not present.


This method comes handy when you want to search something in the array of objects using some attributes present in the object.
consider the example below.


This method operates on arrays, and it removes duplicates in the array.
Consider the following example:


if you ever wanted to extract some values from an array of objects, well the pluck method let’s you do that.
Here is the example:

By merging these two awesome web development frameworks together we can get a pretty nice web development experience, as angular serves as an awesome MVC, and underscore provides a very useful collection of utility methods.
