JavaScript: Basket.js


This article is about one of the common concern for web development
i.e loading time and how it affects on website performance when you need
to load several libraries to your website especially with low internet speed.

So basket.js is one of the solutions for it.
It is a small JavaScript library which loads external JavaScript libraries and also
caches them in local storage, so that on the next page request the external JavaScript does
not have to be requested over the network again, but can simply be loaded from the local storage.
You can also set an expiry time for the cached item.

Let's give a try:

<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/basket.js/0.5.2/basket.full.min.js"></script>
<script>
basket.require({ url:'https://cdnjs.cloudflare.com/ajax/libs/countable/3.0.1/Countable.min.js',expire: 2 });
</script>
</head>
<body>
<h2>Hello, Please check network tab first and then local storage.</h2>
</body>
</html>

So in this example, we have firstly loaded the basket.js and then using basket.require()
we have loaded countable.js which will be cached in localstorage, that you can check in the application tab of developer console of chrome.
So from the next time, it will fetch countable.js library from localstorage instead over a network.
As we have also set expire time i.e 2 hours.
It will catch only till 2 hours, if the expire parameter is not given then by default it is 5000 hours.
There is a lot to explore about this library like passing multiple scripts, methods like  basket.get(), basket.clear(), and basket.remove().

For more details please check this official documentation.

Well as a Node Js developer we know package.json as dependency file where we keep a note of all dependencies of our project. Here we will be looking at what is bin in package.json? To understand this we first need to understand command line application and it's purpose.

Node.js: Extract text from image using Tesseract.

In this article, we will see how to extract text from images using Tesseract . So let's start with this use-case, Suppose you have 300 screenshot images in your mobile which has an email attribute that you need for some reason like growing your network or for email marketing. To get an email from all these images manually into CSV or excel will take a lot of time. So now we will check how to automate this thing.

For Windows 10, you can install  it from here. For other OS you make check  this link. So once you install Tesseract from windows setup, you also need to set path variable probably, 'C:\Program Files\Tesseract-OCR' to access it from any location. Then you need to install textract library from npm. To read the path of these 300 images we can select all images and can rename it to som

Node.js: Bundling your Node.js application to single executable for Windows.

In this article, we will see how to bundle Node.js application to a single executable for Windows. What's the need? Well recently, I had taken a work where I needed to convert pdf's(Of similar format) to excel sheet. So I was reading the pdf's from a folder in desktop and I was storing the output excel sheet into a separate folder on the desktop. I used Node.js for the program. Now the client wanted it to install the program on 25 windows machine and his budget was really low. So it was also not possible for me to install node.js for 25 machines and then install the required dependency for each one. One of the solution: While I was searching for an easy solution I found this amazing npm module pkg . This module can make your node.js app work like plug and play type. No need to install Node.js on the client machine or any other dependency.  It helps to make a commercial or trial version of your node.js application without exposing the source code. I found
