Persistent cache for Mytosis
mytosis-leveldb is a plugin for Mytosis and serves as long-term storage. It's perfect for small-scale servers and electron apps looking for a persistent cache.
Its ease of use and large ecosystem allows for quick prototyping of different backends, like Mongo, Google Sheets, or Azure (to name a few).
Note: This plugin doesn't depend on LevelDB directly. To keep compatibility with all the different platforms (specifically browsers), a level instance must be passed as an argument.
This package is published on npm. You probably know what to do, but here's something you can copy & paste.
# With the yarn goodnessyarn add mytosis mytosis-leveldb# Or with npm, that's cool toonpm install --save mytosis mytosis-leveldb

That's it! Everything you need to get up and running with LevelDB is right there. Reads and writes will go through LevelDB.

You can use level everywhere, from the server to the browser to React Native. It seems every database in existence has a LevelDB plugin for it. Seriously, check the list.
For example, here's how you'd use
mytosis-leveldb in the browser with IndexedDB:
const level =const db =
The same general process applies using
riak-down or any other backend - change the
There's an entire other class of plugins for level too, like hooks, advanced queries, and data visualizations, but I'll leave those for you to explore 🌈
Note: The Mytosis storage plugin spec isn't finished yet. A
.query()method and a way to read keys in bulk are on the spec roadmap.
