Alphanumeric IDs, powered by Nano ID

Import mod.ts directly into your project.

import { sweetid } from "https://deno.land/x/sweetid/mod.ts";

sweetid();
// => CUXuq1

Or use Sweet ID in the command line.

deno run https://deno.land/x/sweetid/cli.ts
# buGdUo

We use Nano ID under the hood to guarantee high-quality, cryptographically secure IDs.

Sweet IDs are alphanumeric and always start with a letter.

The sweetid() function generates IDs with a length 6, 12, 24, or 48 characters. IDs are 6 characters long by default.

Pass in an optional SweetIdSize as the first argument to set the output size of the ID.

sweetid("short" || "s");
// => MkSofu

sweetid("medium" || "m");
// => bzAuoVKRo1rJ

sweetid("long" || "l");
// => XGPCQUqrEVMzMyaU4V52u1LQ

sweetid("xlong" | "xl");
// => dRjFNY7TrZFqizgKLBwWXAQSErCk51gheMFlBNVAZFM5DuLr

Use the --size <SweetIdSize> (-s <SweetIdSize>) flag on the command line to set the output size.

Use the --count <NUMBER> (-c <NUMBER>) flag on the command line to generate multiple IDs of the same length.

Use SweetId and SweetIdSize to add type info to your project. This is great for things like custom wrapper functions.

import type { SweetId, SweetIdSize } from "https://deno.land/x/sweetid/mod.ts";
import { sweetid } from "https://deno.land/x/sweetid/mod.ts";

export function customSweetId(size: SweetIdSize = "long"): SweetId {
  return sweetid(size);
}

NOTE: SweetId is a flexible nominal type and plays nicely with generic string types if needed.
