expo-level v0.3.2

expo-level

abstract-level adapter for react-native-leveldb

Installation

npm install expo-level

Install expo

Because the project use expo-file-system, you also need configure Expo if you use this in a bare React Native Projects.

See: https://www.npmjs.com/package/expo-file-system

Polyfill

The project requires some polyfill, either. You need to configure manually:

TextEncoder object

You need to manually setup a polyfill for TextEncoder. There are multiple ways to do this, one of the way is:

npm install react-native-polyfill-globals

And then include this in your project:

import 'react-native-polyfill-globals/auto'

Nodejs library

Include this in your project:

You may need install buffer@6 first

if (!global.process.cwd) {
  global.process.cwd = () => {
    return '.';
  }
}
if (!(global as any).__dirname) {
  (global as any).__dirname = '.';
}
if (!(global as any).Buffer) {
  global.Buffer = require('buffer').Buffer;
}

Usage

import {SKReactNativeLevel} from "expo-level";

const db = new SKReactNativeLevel("test", {/* options */})

// ...

Issues

Passes nearly all tests of abstract-level except for "async-iterator-test.js".

This issue may be due to the metro bundler, see

• https://github.com/facebook/metro/commit/bf73ed3aa7fec15f1394fd492450163b62b6267a

To run tests, start up the testapp app and click "Start Test".
