URL and cookie safe UIDs
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.
$ npm install uid-safevar uid = require('uid-safe')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.
uid(18, function (err, string) {
if (err) throw err
// do something with the string
})Asynchronously create a UID with a specific byte length and return a
Promise.
Note: To use promises in Node.js prior to 0.12, promises must be
"polyfilled" using global.Promise = require('bluebird').
uid(18).then(function (string) {
// do something with the string
})A synchronous version of above.
var string = uid.sync(18)
