    id-generatorpublic

    id-generator

    Generates unique ids using uuid and an running number.

    Useful for enviroments where the cost of generating a new uuid each time is too high or when id generation is distributed and one does not want to coordinate uniqueness.

    By default, when the counter reaches 2^53 it will reset and a new uuid will be generated.

    Install

        npm install id-generator
    

    Usage

        var Generator = require('id-generator')
        var g = new Generator()
        
        console.log(g.newId()) // outputs: 049f2d25-f1ec-424a-999b-51d2a34aedff.1
        console.log(g.newId()) // outputs: 049f2d25-f1ec-424a-999b-51d2a34aedff.2
        console.log(g.newId()) // outputs: 049f2d25-f1ec-424a-999b-51d2a34aedff.3
     
        g.reset() // reset will occur after 2^53 invocations of newId() by default, but you can change that by doing g.max=123
     
        console.log(g.newId()) // outputs: 4ea9b5d9-e616-45f6-bdf4-11d382062fdc.1
        console.log(g.newId()) // outputs: 4ea9b5d9-e616-45f6-bdf4-11d382062fdc.2
        console.log(g.newId()) // outputs: 4ea9b5d9-e616-45f6-bdf4-11d382062fdc.3
        
        g.on('reset', function(g) {
            console.log(g.prefix) // outputs 4ea9b5d9-e616-45f6-bdf4-11d382062fdc
        })
     
        // Override uuid prefix with something else
        var anotherG = new Generator(function () { return 'bar' })
        console.log(g.newId()) // outputs: bar.1
        console.log(g.newId()) // outputs: bar.2
