Question

Using a filter may prevent chat messages from being sent

My friend and I are currently working on creating a chat room for students at our school to use in their free time. We wanted to make sure the chat remains safe for work, so I attempted to add a filter. However, once the filter was added, no messages could be sent in the chat. When I turned off the filter script by commenting it out, the messages were able to go through without any issues.

This is the filter code that caused the issue:

    var array = array.js
message.replace(array, "****");

Below is the messaging code being used:

        if (message && connected) {
  $inputMessage.val("");
  addChatMessage({
    username: username,
    message: message
  });

  socket.emit("new message", message);
}}

My friend is more experienced with JavaScript and is responsible for the Messaging code, but due to his busy schedule, I am attempting to troubleshoot the issue on my own for now.

To effectively filter out inappropriate words from your text, you can utilize an array called array and break down your message by spaces to examine each word for any offensive terms.

There are two approaches available (though neither is flawless as they may have certain exceptions: it is advisable to opt for a more comprehensive JavaScript library such as npm: bad-words, npm: censor-sensor, or npm: swearjar)

Both strategies involve splitting the message using message.split(' ') and then processing each word individually to determine if any replacements are needed utilizing .map. The first approach checks if the current word matches any term in the array, while the second scans through the array elements to identify if any of them are present in the current word before replacing it with ****

const array = ['badword', 'nsfw']

let message = 'my message is full of badwords which may be nsfw'

message = message.split(' ').map(word => array.includes(word.toLowerCase()) ? '*****' : word).join(' ')

console.log(message)

message = 'my message is full of badwords which may be nsfw'

message = message.split(' ').map(word => array.some(nsfword=>word.toLowerCase().includes(nsfword)) ? '*****' : word).join(' ')

console.log(message)
