Package Exports

uid-safe

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (uid-safe) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

UID Safe

Create cryptographically secure UIDs safe for both cookie and URL usage. This is in contrast to modules such as rand-token and uid2 whose UIDs are actually skewed due to the use of % and unnecessarily truncate the UID. Use this if you could still use UIDs with - and _ in them.

API

var uid = require('uid-safe')

uid(byteLength, [cb])

Asynchronously create a UID with a specific byte length. Because base64 encoding is used underneath, this is not the string length! For example, to create a UID of length 24, you want a byte length of 18!

If cb is not defined, a promise is returned. However, to use promises, you must either install bluebird or use a version of node.js that has native promises, otherwise your process will crash and die.

uid(18).then(function (string) {
  // do something with the string
})

uid(18, function (err, string) {
  if (err) throw err
  // do something with the string
})

uid.sync(byteLength)

A synchronous version of above.

var string = uid.sync(18)
