react-native-leveldb-level-adapter

abstract-level adapter for react-native-leveldb

Passes all 5395/5397 tests of abstract-level in full Buffer support! (The only 2 failing tests are ones where you store non-utf8 compliant character containing buffers into databases that are opened with utf8 keys/values.. which shouldn't occur IRL) (see errorLogBufferTrue.md)

To run tests, start up the example app and run it. The tests are run in a useEffect hook called once at app startup.

(If you get this in tests, it's due to an older version of Babel)

• TypeError: Invalid attempt to iterate non-iterable instance. In order to be iterable, non-array objects must have a Symbol.iterator method
  • Issue description (thanks to this comment here in the facebook/metro repository)
  • "That error is due to an error in the @babel/plugin-transform-for-of plugin. It (mistakenly) tries to convert for await of statements with the same code as for of, and uses the wrong iterator property accessor"
    • Solution : if you encounter this, add "@babel/plugin-proposal-async-generator-functions" to babel.config.js of the application running the app.
    • Note : This should already be fixed

Installation

npm install react-native-leveldb-level-adapter
