How to get the Current Date in ReactNative?

问题

I am building my first ReactNative iOS and Android app. I am an iOS coder with Swift and Obj-C. How do I fetch the current date using ReactNative.

Shall I use Native Modules or is there an ReactNative API from which I can get this data ?

回答1:

The JavaScript runtime in React Native has access to date information just like any other environment. As such, simply:

new Date()

... will give you the current date. Here's the MDN on working with dates in JS.

If you want a good JS library to make working with dates even easier, check out MomentJS.

I used {new Date()} was generating Invariant Violation: Objects are not valid error the following date function worked for me.

const getCurrentDate=()=>{

      var date = new Date().getDate();
      var month = new Date().getMonth() + 1;
      var year = new Date().getFullYear();

      //Alert.alert(date + '-' + month + '-' + year);
      // You can turn it in to your desired format
      return date + '-' + month + '-' + year;//format: dd-mm-yyyy;
}
