jtricerolph 18e24efbeb Add sync error logging, extend error flash, fix unload saves
- Log workforce sync errors to backend stdout so they appear in docker logs
- Extend error flash from 5s to 15s so errors are readable
- Replace sendBeacon (POST-only) with keepalive fetch (PUT) on unload —
  sendBeacon was hitting 404s on all three unload saves

Store information about any JS value in a side channel, using a linked list.

Warning: this implementation will leak memory until you delete the key. Use side-channel for the best available strategy.

Getting started

npm install --save side-channel-list

Usage/Examples

const assert = require('assert');
const getSideChannelList = require('side-channel-list');

const channel = getSideChannelList();

const key = {};
assert.equal(channel.has(key), false);
assert.throws(() => channel.assert(key), TypeError);

channel.set(key, 42);

channel.assert(key); // does not throw
assert.equal(channel.has(key), true);
assert.equal(channel.get(key), 42);

channel.delete(key);
assert.equal(channel.has(key), false);
assert.throws(() => channel.assert(key), TypeError);
