The primary purpose of this package is to make it easy to cache objects and files.

const cache =
  process.env.CACHE_BUCKET_NAME === 'local'
    ? new FileSystemObjectCache(path.join(__dirname, '../.cache'))
    : new S3ObjectCache(
        new S3({
          region: process.env.AWS_REGION,
        }),
        process.env.CACHE_BUCKET_NAME,
        'optional/cache/prefix',
      )

for (let i =0; i < 10; i++>) {
  const value = await cache.getAndCache('test', async (existing: {test: number} | undefined) => {
    await new Promise(resolve => setTimeout(resolve, 100))
    const e = existing ?? {test: 1}
    e.test++
    return e
  }, {
    staleAfterSeconds: 1
  })
  console.log(value)
  await new Promise(resolve => setTimeout(resolve, 500))
}

await cache.put('test', {test: 100})
