Building a Chat System – Part 4

With any chat solution, you run the risk of communication creating some points of conflict. One of those points of contention would be if some naughty words were used in the chat itself.

We have to be careful with worrying about a few naughty words here or there. But in this blog post, I’ll give you a way to blank out unwanted naughty words.

The easiest way I know to solve this problem is with the npm package called “bad-words”.

npm i bad-words
