javascript terminal emulator

How we create a basic web terminal using pure JavaScript without any library or plugin? Solution: See this JavaScript Terminal Emulator Program, Pure JS Web Based Terminal.

Previously I have shared many pure JavaScript programs, but this is advance one this is a web or online terminal.  Basically, a terminal emulator provides a simple way of adding a terminal / command console to your website or web applications.  Where we can put commands related to our services. We can create a web terminal using JavaScript, where we can put the commands and the actions. There are many plugins available to do that, but we can also create it with pure JS.

Today you will learn to create a Pure JS Web Based Terminal program. Basically, there is a black box that will show results and input at the bottom of the box, where you can put commands. There you can say hi then the terminal will reply you back, and you have to type ‘help’ to see all the featured commands list and info. Simply you can get date, time, etc values by typing these. There is directly open website features, you can search in google, youtube, and Wikipedia by putting the site name with keywords (ex. google + put your search query ). And also there are some other webpages open features, when you will give command web development or web dev then webdevtrick blog’s web development category will open automatically. There are many more commands you can check in the JS file.

So, Today I am sharing JavaScript Terminal Emulator Program. There I have used pure JavaScript to create the program, HTML and CSS to create the layout and style it. The best face is a beginner will also understand the JS code and can change the commands and values or create their own commands. You can place this terminal online on your website or project.

If you are thinking now how this JS web-based terminal actually is, then see the preview given below.

JavaScript Terminal Emulator Source Code

Before sharing source code, let’s talk about it. First I have created the main div for the backside gradient section, and placed all other items inside it.  Inside the main div, I have placed another div for the result screen and text input for put commands. I gave unique class names to all the divs, and an ID to the input. Also In the HTML file, I have linked other files like CSS and JavaScript.

Now using CSS I have placed all the elements in the right place, as you can see in the preview. With CSS first I gave basic values like size, position, margin, padding, etc to all the elements. There I have used @keyframe command to create the animations. And used @media query to create a responsive design. I think the style of this program is really impressive.

JavaScript handling here the whole feature in this program. There I have used ‘if’ command to declare conditions and result of basic commands like time and date. After that, I have used JS case: and break;  commands and put command name and their result condition. Also, I have used if{} else{} statements to open websites feature like open google, open youtube, etc. You can change all the commands and their result, and replace these and put your own by copy-paste the format.

Left all other things you will understand after getting the codes, I can’t explain all in writing. For creating this program you have to create 3 files. First file for HTML, second file for CSS, and third file for JavaScript. Follow the steps to creating this program without any error.

index.html

Create an HTML file named ‘index.html‘ and put these codes given below.

style.css

Now create a CSS file named ‘style.css‘ and put these codes given here.

function.js

The final step, create a JavaScript file named ‘function.js‘ and put the codes.

That’s It. Now you have successfully created JavaScript Terminal Emulator Program, Pure JS Web Based Terminal. If you have any doubt or question comment down below.
