Set to one of the built-in generators - uuid.mathRNG (all platforms), uuid.nodeRNG (node.js only), uuid.whatwgRNG (WebKit only) - or a custom function that returns an array of byte values.Įxample: Generate string UUID with fully-specified options uuid. rng - (Function) Random # generator to use. To install the UUID npm package, you can run npm install save uuid given your project is set up with NPM and has the package.json and relevant lock file.random - (Number) Array of 16 numbers (0-255) to use in place of randomly generated values.Uuid.v1( null, arr, 16) // -> // Optionally use uuid.unparse() to get stringify the ids (Future versions of this module may use persistent storage mechanisms to extend this guarantee.)Įxample: Generate string UUID with fully-specified options uuid.v1() // -> "710b962e-041c-11e1-9234-0123456789ab"Įxample: In-place generation of two binary IDs // Generate two ids in an array var arr = new Array( 32) // -> npm package UUID is available to generate a Unique identifier. The randomly generated node id is only guaranteed to stay constant for the lifetime of the current JS runtime.A tiny (130 bytes), secure, URL-friendly, unique string ID generator for JavaScript. Returns buffer, if specified, otherwise the string form of the UUID Generate RFC-compliant UUIDs in JavaScript. offset - (Number) Starting index in buffer at which to begin writing.Default: internal uuid counter is used, as per 4.2.1.2.īuffer - (Array | Buffer) Array or buffer where UUID bytes are to be written. UUIDs can be generated from the command line using uuid. nsecs - (Number between 0-9999) additional time, in 100-nanosecond units.msecs - (Number | Date) Time in milliseconds since unix Epoch.Default: An internally maintained clockseq is used. clockseq - (Number between 0 - 0x3fff) RFC clock sequence.parse: Generate an array of bytes from a UUID string. node - (Array) Node id as Array of 6 bytes (per 4.1.6). Structure and Usage of NodeJS UUID NIL: A string of all zeros.Options - (Object) Optional uuid state to apply. ![]() Generate and return a RFC4122 v1 (timestamp-based) UUID. Compatible with node express and angular ivy engine. Uuid.v4() // -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1' API uuid.v1(]]) js module that returns random text of 128 digits of base 16. Generate v1 UUIDs Make sure you have the necessary prerequisites installed: Node.js and Browserify Install the uuid library: npm install uuid3.4. Here’s an example generating a UUID v4: import Uuid from 'uuid' const uuidV4 Uuid. Uuid.v1() // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a' // Generate a v4 (random) id At first, install the uuid package as a project dependency: npm install uuid Then, import the UUID package and call the method related to the UUID version you want to use. Or in node.js: npm install node-uuid var uuid = require( 'node-uuid') 1.1K minified and gzip'ed (Want something smaller? Check this crazy shit out! ). ![]() ![]()
