I'm also receiving a lot of deprecation warnings. I think those are great to make libraries do the changes as early as possible. however not so great for the end user app dev experience ('cause RN show the yellow warning in the App itself.. maybe they should only be displayed in the console for so called "lowPriorityWarning").
Anyway, so if you are looking for a way to temporarily disable this as I am, I've figured you can do:
require("ReactFeatureFlags").warnAboutDeprecatedLifecycles = false;

Reacted by John Michael Ferraris, Eric Kerr and Tho@gre thanks dude!
Hey, @gre! Where did you placed
warnAboutDeprecatedLifecycles = falsething? I've tried to put it inindex.jswith no luck. I've also restarted and reset cache for metro bundler.I answer my own question. Because
importis moved to the top of the compiled code I've rewritten it torequire. So the code is:require('ReactFeatureFlags').warnAboutDeprecatedLifecycles = false; const {AppRegistry} = require('react-native'); const App = require('./App').default; AppRegistry.registerComponent('iosapp', () => App);
Reacted by Alexey Bulavka and Chen@DimitryDushkin I tried your fix but I am getting a weird error saying reducer is not a function:
require("ReactFeatureFlags").warnAboutDeprecatedLifecycles = false;
const React = require('react');
const { AppRegistry } = require('react-native');
const App = require('./src/containers/App').default;
const rootReducer = require('./src/reducers/index');
const { createStore } = require('redux');
const { Provider } = require('react-redux');
const store = createStore(rootReducer);
const AppContainer = () =>
AppRegistry.registerComponent('todoappnative1', () => AppContainer);
console.log(store.getState());Can you check it what's wrong with my require usage?
@DimitryDushkin I have a separated file that I call polyfill.js, and in my entry point, i'll do
import "./polyfill";at first line. if it important it is the first import so there is not the problem you mentioned.@sameer421 if you have
export defaultinreducers/index.jsyou shouldrequire('...').default;@gre oh, that's clever :)
@DimitryDushkin Thanks it worked. Removed All my warnings.
in your AppRegistry file add an array of messages you want to ignore
console.ignoredYellowBox = ['View #']see http://www.joshualyman.com/2016/03/react-native-debugging-tips/ for more detailsReacted by DimitryThese warnings got into the release in this state by accident. It wasn't intentional.

Since we updated to 0.54, we received a lot of deprecation warnings.
The reason that we updated was to address this issue. App works as expected, however, warnings are showing up.
Do we have a document or a website showing the full list of deprecations so we can act accordingly? Thank you!
