react-native-mmkv VS Leon

react-native-mmkv is a wrapper around MMKV that allows you to easily implement secure storage in your app. It is arguably the fastest key-value storage for React Native apps

Why do you need to access the db from the file system? Can you just use something like https://github.com/mrousavy/react-native-mmkv ?

By using libraries like Reanimated, React Native MMKV, and React Native Skia, you leverage the native thread. However, I know there are developers building amazing things who think outside the box. I'm always thrilled when I read engineering blogs from companies like Netflix, Meta, and Shopify. They create solutions beyond the limits.

mmkv is not really designed to be used for “heavy” writes, or often changing values. But more as e.g. NSUserDefaults. The storage keeps growing over time which may cause memory issues if used wrongly. Here’s a related github issue: https://github.com/mrousavy/react-native-mmkv/issues/440

Persistence - React Native MMKV (supports encryption natively and easily integrates with TanStack Query via persistQueryClient)

if you need to store something small and simple use whatever. if is complex and speed is important use something performant. realmDB, https://github.com/mrousavy/react-native-mmkv and others are good fit for the job.

Screw you all, I'll use MMKV as my Local DB: please do not, as explained here.

It's indeed suspicious. You're sending your voice samples, your various services accounts, your location and more private data to some proprietary black box in some public cloud. Sorry, but this is a privacy nightmare. It should be open source and self-hosted like Mycroft (https://mycroft.ai) or Leon (https://getleon.ai) to be trustworthy.

I literally had this thought a couple of days ago and went down a small rabbit hole looking into it too! There's some stuff out there (I saw Mycroft and Coqui mentioned in the comments already, also check out Leon, Jarvis, and OA although not sure they all deploy to Linux) but ultimately, I just don't think the tech is there yet.

Mycroft is pretty decent and there are a few other similar open source projects if you're interested (https://github.com/MycroftAI, https://github.com/leon-ai/leon)

Take a look at Leon I'm not sure it's what you're looking for but it look pretty awesome.

Leon is an open-source personal assistant who can live on your server. He does stuff when you ask him to. You can talk to him and he can talk to you. You can also text him and he can also text you. If you want to, Leon can communicate with you by being offline to protect your privacy.

There is also Leon - https://getleon.ai. But I’m not using any of the self hosted yet.
