AsyncStorageRepl provides you to access remote ReactNative application's AsyncStorage from your node REPL.

npm i async-storage-repl -D

1. Write bellow code in your ReactNative Application.

import AsyncStorageREPL from 'async-storage-repl';
AsyncStorageREPL().connect();

2. Start node REPL.

./node_modules/.bin/async-storage-repl

3. Let's get access your ReactNative application's storage from your node REPL.

$ ./node_modules/.bin/async-storage-repl
> RNAsyncStorage.getItem('item1')
null
> RNAsyncStorage.setItem('item1', 'nice value!')
null
> RNAsyncStorage.getItem('item1')
'nice value!'
> RNAsyncStorage.getAllKeys()
[ 'reduxPersist:timeline',
  'item1',
  'reduxPersist:auth',
  'reduxPersist:nav' ]

example

AsyncStorageREPL provides RNAsyncStorage on your node REPL as a global object. You can access AsyncStorage's all APIs via this object.

• getAllKeys(): string[]
• getItem(key: string)
• setItem(key: string, value: string)
• removeItem(key: string)
• mergeItem(key: string, value: string)
• clear()
• flushGetRequests()
• multiGet(keys: string[])
• multiSet(keyValuePairs: string[][])
• multiRemove(keys: string[])
• multiMerge(keyValuePairs: string[][])

AsyncStorageREPL's methods args are guaranteed type-safe by flow-runtime.

> RNAsyncStorage.getItem(1)
RuntimeTypeError: key must be a string

Expected: string

Actual: number

You can save & load RN Application AsyncStorage data.

dump() provides you getting dump. load(string[][]) provides you loading dump.

> const data = RNAsyncStorage.dump()
undefined
> data
[ [ 'comments', '["foo","bar","baz"]' ] ]
> fs.writeSync('./dump1.txt', JSON.stringify(data))

> const data = JSON.parse(fs.readSync('./dump1.txt'))
> RNAsyncStorage.load(data)
null

AsyncStorageREPL() accepts an object with a host and port key. Port key must be matched REPL side. You don't need specify a host in case of running on a simulator. but in case of runnning on a real device, specify your computer host.

AsyncStorageREPL({ host: 'localhost', port: 8080 }) // default
  .connect();

You can specify portNo --port option.

async-storage-repl --port 8080
