...ANSWER

QUESTION
ANSWER
Answered 2018-Jul-28 at 17:42The component will re-render when one of the props or state changes, try using PureComponent
or implement shouldComponentUpdate()
and handle decide when to re-render.
Keep in mind, PureComponent
does shallow object comparison, which means, if your props have nested object structure. It won't work as expected. So your component will re-render if the nested property changes.
In that case, you can have a normal Component
and implement the shouldComponentUpdate()
where you can tell React to re-render based on comparing the nested properties changes.
QUESTION
I am using react-native-simple-store and have written the below function to update the property of a supplied object stored in an array of objects. To do so, I used the method mentioned in issue #31 for deleting items.
Trouble is since I'm using .push, updating an item causes it to be rendered at the bottom of the array. This causes items to move in the FlatList unnecessarily.
Is there a more efficient method for updating a property of an object within the array (without causing this issue using .push)?

QUESTION
I have been following this tutorial to integrate redux into my react native app.
https://github.com/jlebensold/peckish
On my Home view, I'm not able to call the functions from my action folder.
One difference is that I'm using react-navigation in my app. Wonder if I need to integrate redux with react navigation to be able to use redux for all data?
Below is the full implementation code I have been doing.
On the Home screen, I call the fetchSite function on ComponentDidMount to launch an async call with axios. But I can't even access to this function.
Sorry for this long post but I can't figure out how to make this work so quite difficult to make a shorter code sample to explain the structure of my app.
Let me know if any question.

QUESTION
I'm using React-Native with Redux, where I want to render a button if the logged in user is eligible. Somehow the button is not showing!
For storing data I'm using react-native-simple-store
...ANSWER
Answered 2017-Apr-26 at 13:38The Button
is not showing up because store.get(storage.userKey)
is returning a promise
of a user
object which is then being mapped into a component (or false
) using the then
function.
As you aren't returning the result of the then
function, the result of renderIfEligible
is always undefined
(your returns
are for the lambda function).
Unfortunately for you, just changing the function to return store.get(storage.userKey).then(user => {...})
wont help you as then it will be returning a promise
of a component (or false
), which is still unable to be rendered.
Take a look at this answer for ideas on how to get around this.
QUESTION
I am using React Native along with Redux for an app I am building. I am also using two npm modules, react-native-simple-store, and redux promise. I will explain the use of each as I continue explaining my problem.
I have a basic action creator that fires in a componentWillMount method. The purpose of this action creator is to retrieve an array of data from the user's device. I use react-native-simple-store to do this, as it always returns the data you request as a promise. Here is my action creator:
...ANSWER
Answered 2017-Jun-15 at 14:55According to your reducer, your action should be in capital letter :
export const GET_ALARMS = 'GET_ALARMS'
.
Your switch case is case sensitive. That's why you never enter into the case.
