randomstring¶

Random characters on demand — codes, temp passwords, and "guess this" tokens.

What is it?¶

randomstring generates random alphanumeric strings with configurable length and character sets. Shorter and more flexible than a full UUID when you need a promo code, one-time password, or referral slug.

Access it as modules.randomstring.

How to use¶

Generate a 10-character string:

let str = modules.randomstring.generate(10)
// "a1b2c3d4e5"

Pass a number for length, or an options object for finer control.

API reference¶

Options object:

Try it¶

Generate a promo code¶

Bot sends to chat:

let code = modules.randomstring.generate({
  length: 8,
  charset: "alphanumeric",
  readable: true
}).toUpperCase()

Bot.sendMessage("Your promo code: " + code)

Create a one-time password¶

Save it in db for user to verify later:

let otp = modules.randomstring.generate({ length: 6, charset: "numeric" })
db.user.set("otp", otp)
db.user.set("otp_expires", Date.now() + 300000)  // 5 minutes

Bot.sendMessage("Your one-time code: " + otp + " (expires in 5 min)")

Numeric PIN¶

let pin = modules.randomstring.generate({ length: 4, charset: "numeric" })
Bot.sendMessage("Your PIN: " + pin)

Limits¶

Notes¶

• Sync — no await needed
• For standard UUIDs (longer, collision-resistant), see UUID
• readable: true helps when humans need to type the code
• Official package: randomstring on npm
