block-sequence-redis

A redis implementation of block-sequence.

Usage

const BlockArray = require('block-sequence').BlockArray
const init = require('block-sequence-redis')

// Initialise the redis Block Sequence Driver
init({ host: '127.0.0.1' }, (err, driver) => {
    if (err) throw err

    // Ensure the sequence exists
    driver.ensure({ name: 'my-sequence' }, (err, sequence) => {
        if (err) throw err

        // Create a block array containing 1000 ids per block (defaults to 2 blocks)
        const idGenerator = new BlockArray({ block: { sequence: sequence, driver: driver, size: 1000 } })

        // Grab the next id
        idGenerator.next((err, id) => {
            if (err) throw err
            console.log(id)
        })
    })
})
