uid2

Generate unique ids. Pass in a length and it returns a string.

npm install uid2

Without a callback it is synchronous:

const uid = require('uid2');

const id = uid(10);
// id => "hbswt489ts"

With a callback it is asynchronous:

const uid = require('uid2');

uid(10, function (err, id) {
  if (err) throw err;
  // id => "hbswt489ts"
});

Imported via uid2/promises it returns a Promise:

const uid = require('uid2/promises');

async function foo() {
  const id = await uid(10);
  // id => "hbswt489ts"
}
