@directus/memory

Directus has various different needs for ephemeral storage that's synced between multiple processes for the same
Directus Projects. To streamline that setup, this package exports three classes that are used for everything related to
ephemeral storage:

- Cache
- Bus
- Limiter

Kv

The Kv class is a simple key-value store

$3

``ts
import { createKv } from '@directus/memory';

const cache = createKv({
type: 'memory',
});

await cache.set('my-key', 'my-value');
`

Cache

The cache class is a Kv class extended with an LRU store

$3

`ts
import { createCache } from '@directus/memory';

const cache = createCache({
type: 'memory',
maxKeys: 500,
});

await cache.set('my-key', 'my-value');
`

Bus

The bus class is a pub-sub abstraction. The memory type bus just handles local handlers, which adds no benefit next to
having a shared API for using pubsub.

$3

`ts
import { Redis } from 'ioredis';
import { createBus } from '@directus/memory';

const bus = createBus({
type: 'redis',
redis: new Redis(),
namespace: 'directus',
});
`

Limiter

The limiter class is a basic shared rate limiter.

$3

`ts
import { createLimiter } from '@directus/memory';

const limiter = createLimiter({
type: 'memory',
points: 10,
duration: 5,
});
