incremental-id

unique client ids using monotonic increasing numbers with no upper bound.

only unique for a single client during a single session, not across clients or sessions.

based on code from bigeasy/monotonic

npm install --save incremental-id

example

const IncrementalId = require('incremental-id')

while (true) {
  const incrementalId = IncrementalId()
  process.stdout.write(incrementalId + ' ')
}

// 0 1 2 3 4 5 6 7 8 9 a b c d e f 10 11 12 13 14 15 16
// 17 18 19 1a 1b 1c 1d 1e 1f 20 ......................
// ... ffffffff 100000000 100000001 100000002 100000003
// ... 1fffffffffffff 20000000000000 20000000000001

usage

IncrementalId = require('incremental-id')

incrementalId = IncrementalId()

incrementalId returned will be a string, so we are not bounded by Number.MAX_SAFE_INTEGER
