ewd-qoper8-redis

library0.1.1jsnpmunverified

Integrates the Redis-based Global Storage database emulation (ewd-redis-globals) with ewd-qoper8 worker processes. Version 0.1.1 is the current and only release. This module simplifies setting up a Redis-backed Global Storage and DocumentStore inside ewd-qoper8 workers, automatically handling connection opening/closing and event wiring. It is designed for use with ewd-qoper8's worker event system. The package has not been updated since 2016 and is unmaintained, with limited documentation and no active development.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

ewd-qoper8-redis

✓ const connectRedisTo = require('ewd-qoper8-redis');

✗ import connectRedisTo from 'ewd-qoper8-redis'; // No ESM export

CommonJS-only, no default export. Must use require().

connectRedisTo

✓ const connectRedisTo = require('ewd-qoper8-redis');

✗ const { connectRedisTo } = require('ewd-qoper8-redis'); // Not a named export

The module exports a single function; destructuring will result in undefined.

dbOpened event

✓ this.on('dbOpened', function(status) { ... });

✗ this.on('dbOpened', status => { ... }); // Arrow function may not bind 'this' correctly in some contexts

Use regular function to preserve 'this' context inside the ewd-qoper8 worker.

Shows how to integrate ewd-qoper8-redis in an ewd-qoper8 worker by requiring the module in the 'start' event and handling dbOpened, dbClosed, and DocumentStoreStarted events.

// In your ewd-qoper8 worker module this.on('start', function(isFirst) { const connectRedisTo = require('ewd-qoper8-redis'); connectRedisTo(this); }); this.on('dbOpened', function(status) { console.log('Redis was opened by worker ' + process.pid + ': status = ' + JSON.stringify(status)); }); this.on('dbClosed', function() { console.log('Redis connection closed'); }); this.on('DocumentStoreStarted', function() { console.log('DocumentStore is ready'); });

Debug

Known issues

gotchaThe module must be used inside an ewd-qoper8 worker's 'start' event; it will not work outside of that context.

fix

Ensure require('ewd-qoper8-redis') is called only within the worker's 'start' event handler.

affects: >=0.0.0

gotchaThe module does not support ESM import syntax; only CommonJS require() works.

fix

Use const connectRedisTo = require('ewd-qoper8-redis'); instead of import.

affects: >=0.0.0

gotchaThe exported function is not a named export; destructuring will yield undefined.

fix

Assign the entire require result to a variable: const connectRedisTo = require('ewd-qoper8-redis');

affects: >=0.0.0

gotchaArrow functions used in event handlers may lose the correct 'this' context for the worker.

fix

Use regular function expressions (function() { ... }) in event handlers like 'dbOpened' and 'start'.

affects: >=0.0.0

Errors

Common errors & fixes

TypeError: connectRedisTo is not a function

Importing the module incorrectly (e.g., using import or destructuring)

fix

Use const connectRedisTo = require('ewd-qoper8-redis'); and call connectRedisTo(this);

Cannot find module 'ewd-qoper8-redis'

Module not installed or npm install failed

fix

Run 'npm install ewd-qoper8-redis' in your project directory.

dbOpened event not firing

The require call is placed outside the 'start' event handler, or Redis is not available.

fix

Ensure require('ewd-qoper8-redis') is inside the worker's 'start' event, and that Redis server is running on localhost:6379.
