 What's up guys! My question is: Has any form or tool been created that allows data to be saved in an offline database if the customer's internet goes down? I will explain better, my application is Web, made in .Net, runs entirely on the Browser and at first, it will record everything in the online database, but what if the client connection drops? I would need this data to be recorded on the client's machine locally, so that when the connection comes back, all this information stored locally would be posted in the online database. Any idea?

Thank you.

What I have tried:

Google, books and friends. And now codeproject.

The best thing would be to handle such situations in your code.

For Javascript something exists that fits your description PouchDB:
best-indexeddb-wrapper-libraries~pouchdb[^]

Another option might be to choose a resilient database like CockroachDB that are designed for such calamities, but that would probably be even more complex: what-are-the-easiest-database-engines-to-scale~cockroachdb[^]

And if you are using Entity Framework:
