To validate UUID in NodeJS, we can either use NPM UUID package or use custom regular expressions. We can write different regular expressions to validate different versions of UUID. Custom regular expressions to Validate UUID Below is the code.Ĭonst uuidVersion = uuid.version(uniqueId) 2. To check the version of UUID, we can use version() method of UUID package. A UUID can have different versions from 1 to 5. With the help of UUID package, we can check the version of the UUID. This method returns 'true', if the uuid is valid else returns false.

In the third line, we are validating UUID with the help of validate method. In second line, we are declaring a custom uuid number. In the first line, we are importing UUID NPM package.

Below is the sample code.Ĭonst uniqueId = '3112b3db-c1ef-4cc2-994b-306d75834277' Ĭonst isValid = uuid.validate(uniqueId) //return true as Valid, false as Invalid The following tutorial shows how to use uuid() from Node.js module react-uuid. To validate UUID in NodeJS, we can use validate method of UUID package. To use UUID package, we can use below command to include in our project.

We can write our own custom regular expressions to validate.

Line 3 generates the UUID and saves it in the variable, myuuid. There are also functions available for generating version 1, 3 and 5 UUIDs. Thanks goes to these wonderful people ( emoji key): 💻Ĭopyright (c) 2018-2021 Short Unique ID Contributors.To validate UUID (GUID) in NodeJS, we can use below options: Line 1 imports the version 4 UUID function.

This repo and npm package started as a straight up manual transpilation to ES6 of the short-uid npm package by Ankit Kuwadekar. To find out more about the math behind these functions please refer to theĪPI Reference. To 1, higher the uniqueness and thus better the quality). 'quality' of the combination of given dictionary and UUID length (the closer Of hitting a duplicate in a given number of rounds (a collision) and theįunction uniqueness() which provides a score (from 0 to 1) to rate the Cryptographically strong random generation on supporting platforms - 1.

Features: - Generate RFC4122 version 1 or version 4 UUIDs - Runs in node.js and all browsers. The function collisionProbability() function to calculate the probability Simple, fast generation of RFC4122 UUIDS. If you change the dictionary and/or the UUID length then we have provided NodeJS UUIDs are generated by advanced algorithms, making it almost impossible for a collision to occur. So, given the previous values, the probability of generating a duplicate Out of the box this library provides a shuffled dictionary of digits fromĠ to 9, as well as the alphabet from a to z both in UPPER and lower case, This largely depends on the given dictionary and the selected UUID length. What is the probability of generating the same id again?
