Create File Sharing App with JavaScript With Source Code
Published: 2023-06-19 06:31:43

This project is totally based on sharing of files over the servers which is often referred to as a web app, which means web application.

Let me give a short intro of what is a web app with an example.

A web application is an application program that is stored under remote servers and used to deliver over the network with the help of a browser interface. Examples of web applications are online forms, shopping carts, conversion of files, and email programs like Gmail, which come under the web application category.

Likewise, we have created a web app with a **[File Sharing App](https://www.codewithrandom.com/2023/02/21/file-sharing-web-app-javascript/)** using JavaScript in which the user can upload files over the internet and could see a preview of uploaded files with details before sharing. Also additionally it contains the size details of files sent and received with the date and time of the file. We could also see the recent files uploaded and received in the current section and the details of the received file.

So let us move on to start working on a project, first, we would add html code :

## Html Code For File Sharing App:

Now we have added the html code for the file sharing project. In this html code, we firstly added a search bar to search the files sent and received. We have included more section tags for adding specific elements like a file upload box, a button for upload, a download icon, and send icon for sharing files.

As it is a web app we have used bootstrap for aligning contents accurately for every screen size. You can see that in every div tag we have used a bootstrap snippet to alignment, as it is the best option for reducing the lines of code for a specific element's action on a different screen.

So as we now saw the html and its purposes included, it's time to move on to css to design the elements and make them look attractive. The css snippet for a respective project is down below.

## CSS Code For File Sharing App:

As for the html part, now we have come to the css part... Let's get started.

Firstly we have set the box-sizing to border-box and height to 100 view-port height to make the contents align to the center of the screen. Secondly, we used flex-box, and grid as major because it is a web app which means the design content would look the same on every device like colors, sizes, etc.

As we have now included specific icons and designed the icons with various colors for various actions. Images like docs, apps, video, audio, and download have been included so that we can narrate the file as with the help of specific images.

Last we used media queries to make some contents be changed in small screen sizes like menu bar hidden/visible with various link options and also changes in width and height of boxes used and lot more.

So that's for css, and one more thing to do is add java script, the explanation for the script is afterward of javascript code.

## Javascript Code For File Sharing App:
```
$(document).ready(function () {
  $("a#pageLink").click(function () {
    $("a#pageLink").removeClass("active");
    $(this).addClass("active");
  });
  
  $(".btn-show-left-area").click(function () {
    $(".left-area").removeClass("show");
    $(".left-area").addClass("show");
  });
  
  $(".btn-show-right-area").click(function () {
    $(".right-area").removeClass("show");
    $(".right-area").addClass("show");
  });
  
  $(".btn-close-right").click(function () {
    $(".right-area").removeClass("show");
  });
  
  $(".btn-close-left").click(function () {
    $(".left-area").removeClass("show");
  });
});

$('.main-area').scroll( function() {
    if ($('.main-area').scrollTop() >= 88) {
       $('div.main-area-header').addClass('fixed');
    }
    else {
       $('div.main-area-header').removeClass('fixed');
    }
});
```
Here we came to the js part, in this, we are getting the menu bar element with the help of getelementbyid property in order to make the menu bar visible after clicking and hide it when clicked again. But it works on smaller screen sizes like mobile and tablet to look attractive and plays responsive design.

And the active list property was used to determine the current page with changes in specific content's background color, also we used the scroll property to discover the efficient visit of particular contents on the page. Simply relocates to a specific part of the page instantly.

So that's for javascript, now we can view our project output of how it works and look.

Hey there! We came to an end that's what the project looks like when we implement the code. Use the code mentioned below to make use of this project. Include correct links from official websites to avoid encountering errors.

Also, the project ui is similar to android ui as it is a web application. Simply it might vary in colors and effects on different screens.
