How to make a messenger on JavaScript

In this article, we will consider how to create a javaScript messenger with an example of using WebSocket APIs.

Creating a Messenger with JavaScript

Creating a messenger with JavaScript is a great way to add interactivity to your website. This can be done by using a combination of HTML, CSS and JavaScript. By using these three technologies together, you can create a messaging platform that allows users to communicate with each other in a secure and reliable way. In this tutorial, we will go through the steps of creating a messenger with JavaScript.

Step 1 - Set Up HTML and CSS

The first step when creating a messenger with JavaScript is to set up the HTML and CSS. This will help create the basic structure of the chat window. The HTML should include a form to enter a message, a button to send the message, an area to display the messages, and any other elements that you wish to include.

In the CSS, you will set up the styling of the elements. This will include setting the size of the chat window, setting the font size of the text, setting the color of the text, and any other styling that you wish to apply. Once the HTML and CSS is set up, the next step is to add the JavaScript.

Step 2 - Add JavaScript

Once the HTML and CSS is set up, the next step is to add the JavaScript. This will include writing the code for the function that will be used to send messages, and a function to receive messages. The following code shows a simple example of a function that can be used to send messages:

function sendMessage(message) {
  // code to send message
}

The function takes a message as an argument, and then sends the message to the server. The server will then broadcast the message to all the users that are connected to the chat. When the server receives a message, it will also call a function to receive the message. The following code shows a simple example of a function that can be used to receive messages:

function receiveMessage(message) {
  // code to receive message
}

The function takes a message as an argument, and then displays the message in the chat window. This can be done by using the HTML elements that were set up in the first step. Once the send and receive functions have been written, the next step is to add the code that will be used to connect to the server and send and receive messages.

Step 3 - Connect to Server and Send and Receive Messages

The final step is to add the code that will be used to connect to the server and send and receive messages. This will include writing the code to connect to the server, and then the code to send and receive messages. The following code shows a simple example of a function that can be used to connect to the server:

function connectToServer() {
  // code to connect to server
}

The function will use the WebSocket API to connect to the server. Once the connection is established, the code will then call the send and receive functions to send and receive messages. This code can be written using JavaScript, and it will allow the messenger to communicate with the server and send and receive messages.

Conclusion

Creating a messenger with JavaScript is a great way to add interactivity to your website. By using HTML, CSS, and JavaScript together, you can create a messaging platform that allows users to communicate with each other in a secure and reliable way. This tutorial has gone through the steps of creating a messenger with JavaScript, including setting up the HTML and CSS, adding the JavaScript, and connecting to the server and sending and receiving messages.
