Canto is a value-added Redis client library (v0.1.3) that provides high-level abstractions like a Cache class for composing Redis operations and managing data structures. It wraps the node_redis client and exposes a simple callback-based API. The package is in early development with sparse documentation and limited community adoption. It is not actively maintained (last release 2014) and is not recommended for new projects.

Code
Verified usage

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

Cache
✓ import { Cache } from 'canto'
✗ const Cache = require('canto').Cache
ESM import is the standard in modern Node.js; CommonJS require with destructuring also works but is less idiomatic for ESM.
default
✓ import canto from 'canto'
✗ import * as canto from 'canto'
The package does not have a default export; only named exports. Attempting default import will result in undefined.
require (CommonJS)
✓ const { Cache } = require('canto')
✗ const Canto = require('canto'); new Canto.Cache()
The CommonJS pattern is to destructure the named export directly.

Initializes a Cache instance with Redis configuration, stores an object with TTL, then retrieves it.

const redis = require('redis'); const { Cache } = require('canto'); const cache = new Cache({ namespace: 'test', ttl: 5000, redis: { host: 'localhost', port: 6379 } }); // Store an object cache.put({ value: { name: 'example' }, ttl: 10000 }, (err, key) => { if (err) console.error(err); console.log('Stored under key:', key); // Retrieve the object cache.get(key, (err, value) => { if (err) console.error(err); console.log('Retrieved:', value); }); });

Known issues
deprecatedPackage is unmaintained since 2014. No updates for compatibility with newer Redis or Node.js versions.
fix
Consider using ioredis or redis-om for modern Redis features.
affects: >=0.1.3
gotchaCache constructor requires 'redis' configuration; if omitted, it silently fails or throws an unclear error.
fix
Always provide a valid redis object with host and port.
affects: >=0
gotchaThe 'Cache.put' method expects either an object with 'value' and optional 'ttl', or a direct value. Misusing these signatures may cause unexpected behavior.
fix
Use the documented signature: cache.put({value: obj, ttl: ms}, callback) or cache.put(value, callback).
affects: >=0
gotchattl is in milliseconds, but Redis expects seconds. The library may not convert correctly.
fix
Check source code or test thoroughly; consider converting manually: ttl/1000.
affects: >=0
Errors
Common errors & fixes
Error: Redis connection to localhost:6379 failed - connect ECONNREFUSED
Redis server is not running or not accessible at the specified host/port.
fix
Start Redis server with 'redis-server' or update the Redis configuration in Cache constructor.
TypeError: cache.put is not a function
Import error: using wrong export or flawed require/import.
fix
Ensure correct import: const { Cache } = require('canto'); then instantiate: const cache = new Cache({...});
