React native exaple for AsyncStorage with create, get, update, remove

[alexicum]

Trying to use feathers-localstorage with React Native and AsyncStorage.

Hang on create, get. Can not find RN example on base service functions: get, update, remove.

Documentation has code for ReactNative with: import feathers from 'feathers'; But in chat example: import feathers from 'feathers/client'

How are you using it? Try to add a .catch(error => console.error(error)) to your service calls (e.g. app.service('myservice').then().catch(error => console.error(error))) to see if there is an error.

Thanks! It helps to understand what's going on without examples.

Previously I had successfully remove item without id with command: Storage.remove(Number.NaN);

Now I have item with "id":null (don't ask me how :) ) and no ideas about how to remove it. Receiving: Error: No record found for id 'null'(…) with both code:

Storage.remove(null);

Storage.find()
  .then(tokens)
    for(let token of tokens) {
      Storage.remove(token.id)
        .then((removedToken) => {
          if (removedToken)
            console.log('removed: ' + JSON.stringify(removedToken));
        })
        .catch(error => console.error(error));
...

My storage items:

find(). tokens array: [{"id_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VybmFtZSI6ImEiLCJpZCI6MiwiaWF0IjoxNDY4MzE0Mzk2LCJleHAiOjE0NjgzMzIzOTZ9.Vep46JizCMLc03bL0-SXpxf1MG6LCduzkGGkOlG_BW8","id":1},{"id_token":"eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VybmFtZSI6ImEiLCJpZCI6MiwiaWF0IjoxNDY4MzE0MDk0LCJleHAiOjE0NjgzMzIwOTR9.iL3WrUkjvqAHwusBH6KoQCjigS7TDZAAKLJBSIHjwJw","id":null}]

The id being null shouldn't really be possible but you can probably remove it manually from AsyncStorage with something like

const storageKey = 'feathers';

AsyncStorage.getItem(storageKey).then(JSON.parse)
  .then(data => data.filter(current => current.id !== null)).
  .then(filteredData => AsyncStorage.setItem(storageKey, JSON.stringify(filteredData));
