Is there any way to disable all the errors and warnings that appear in the console?

Question

I don't want to show the warnings in the console for a certain development environment. Is there any way to achieve that? My application was bootstrapped using create react app.

Answer 1

Since you are using React, my guess is you are already using babel. There's a plugin for that purpose. It's called babel-plugin-transform-remove-console . This will exclude all console.log 's statement during the build process.
Install that in your app and configure it via .babelrc as follows:

{
  "plugins": ["transform-remove-console"]
}

You can also specify the variant(s) of the console functions to exclude:

{
  "plugins": [ ["transform-remove-console", { "exclude": [ "error", "warn"] }] ]
}

My advise is to not use console logs in your code except necessary.

Answer 2

In my App.js I have the following code for accomplishing this:

import { YellowBox } from 'react-native';

componentDidMount() {
    // The following lines are a workaround
    // in order to stop getting warnings about timer
    // See: https://github.com/firebase/firebase-js-sdk/issues/97#issuecomment-365456531
    YellowBox.ignoreWarnings(['Setting a timer']);
    const _console = _.clone(console);
    console.warn = message => {
      if (message.indexOf('Setting a timer') <= -1) {
        _console.warn(message);
      }
    };
}
