An abstraction for cache providers, it exposes a common interface for different ways to cache data
It suports
- Redis - luin/ioredis
- MemCached - 3rd-Eden/memcached
- In memory - ptarjan/node-cache
$ npm install cache-layer --save- Retrieves a value for a given key
- Store a value for a given key
- If time isn't passed in, it is stored forever
- Delete value for a given key
- Check if key exists on cache
const client = Cache.create({
provider: 'in-memory',
ttl: 2000 // a defautt TTL (miliseconds)
});To use memcached you have to inform a server or it will set a localhost as default. So, to use it locally, you need to install memcached. If you have a memcached server, just inform the host
sudo apt-get install memcachedconst client = Cache.create({
host: 'localhost:11211' // if any host was informed, it will set localhost as default
provider: 'memcached',
ttl: 2000 // a defautt TTL (miliseconds)
});All available options to create memcached instance: https://raw.githubusercontent.com/3rd-Eden/memcached/master/README.md
const client = Cache.create({
provider: 'redis',
host: 'redis.com.br',
container: 'cache',
port: 6379,
ttl: 2000, // a defautt TTL (miliseconds)
keyPrefix: 'cache:',
lazyConnect: true,
maxRetriesPerRequest: 0
});The TTL is in ms, you can pass a default value, or add as a third parameter on add method.
The package implements zeit/ms, so is possible to use a string to define the TTL with zeit/ms format
const done = await client.add('hashKey', { name: 'John' }, 1000);
const result = await client.get('hashKey');
const done = await client.add('hashKey', { name: 'John' }, '1s');
const result = await client.get('hashKey');
const done = await client.add('hashKey', { name: 'John' }, '1d');
const result = await client.get('hashKey');All available options to create ioredis instance: https://raw.githubusercontent.com/luin/ioredis/f4fe62f231b33b28fda1cb28b4f5690655007b80/API.md
