Package Exports

block-sequence-postgres

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (block-sequence-postgres) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

A PostgreSQL implementation of block-sequence.

Usage

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

// Initialise the PostgreSQL Block Sequence Driver
init({ url: 'postgres://username:password@localhost/bs_test' }, (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)
        })
    })
})
