Caching

• We cache using redis, through the @adonisjs/cache package: import cache from "@adonisjs/cache/services/main"

const result = await cache.getOrSet({
  key: `<unique cache key for item>`,
  factory: async () => {
    // perform the operation here and return its result
  },
})

• We can clear the cache with node ace cache:clear
• You can associate a cache entry with one or more tags to simplify invalidation. Instead of managing individual keys, entries can be grouped under multiple tags and invalidated in a single operation.

await cache.getOrSet({
  key: 'foo',
  factory: getFromDb(),
  tags: ['tag-1', 'tag-2'],
})

await cache.deleteByTags({ tags: ['tag-1'] })

• On exceptions, the factory will wrap the actual exception. Use import { safeCacheOperation } from '#services/cache' for bubling up the actual exception.
