I'm relatively new to JavaScript, and I'm looking to create something like a Wordle clone. Like Wordle, I want to generate a new word each day for all users. I've seen solutions with a random number generator that stores the number in localstorage. However, wouldn't this mean each user who goes on the website would have a different number? Is there a simple way to generate the same number for all users on a site?
You can make your own pseudo random generator, these aren’t actually random but they generate numbers based on a seed (which will be the date)
// Get the day of the month with Date object
const day = new Date().getDate();
// And the month to prevent repeats
const month = new Date().getMonth();
Then you can create your function.
To make it seem even more random, you can get the middle numbers and use those.
function random(){
// Crazy math stuff
let num = Math.round((day+4) / month * 39163).toString();
// To convert it back to a number, use the + operator before parentheses
// Don’t forget to use % on the max value, I just put 31 as a placeholder
return +(num[2] + num[3]) % 31;
}
This can be changed to fit your needs ^
This will be the same for every user for the entire day since it is pseudo random and based on a seed
Localstorage is a browser feature, It exists only in the client.
You Will need to persist the data somewhere, a database (MySQL, postgres, etc..) or in a file
The easiest way is in a file, you can search Google "save data to file node.js"
