hmm.. init() is async, can you wait for each to finish at first?

// use this if you don't have top-level await yet in your node version: https://v8.dev/features/top-level-await
(async () => {


  const productStorage = storage.create({ dir: 'cache_products',ttl: true, forgiveParseErrors: true }); 
  await productStorage.init();
  
  const reviewStorage = storage.create({ dir: 'cache_reviews',ttl: true, forgiveParseErrors: true }); 
  await reviewStorage.init(); 
  
  const suppliersStorage = storage.create({ dir: 'cache_suppliers',ttl: true, forgiveParseErrors: true }); 
  await suppliersStorage.init();


  // ... rest of your code here
})();

from node-persist.

So how did you fix this?

from node-persist.

akhoury commented on August 13, 2024

don't use the same folder or parent folder for 2 different instances of Storage.

from node-persist.

@akhoury I am using 3 separate storages in 3 different cache directory and still getting the illegal operation error every few minutes:

const productStorage = storage.create({ dir: 'cache_products',ttl: true, forgiveParseErrors: true }); productStorage.init();
const reviewStorage = storage.create({ dir: 'cache_reviews',ttl: true, forgiveParseErrors: true }); reviewStorage.init();
const suppliersStorage = storage.create({ dir: 'cache_suppliers',ttl: true, forgiveParseErrors: true }); suppliersStorage.init();

Any idea what the issue could be?

from node-persist.
