How to use javascript library like moment.js in

Question

What is the recommended way to use javascript built-in libraries in native response? Are there any specific restrictions?

Answer 1

Easy peasy! From the root of your project, simply run:

npm install moment --save 

Then you can import it into your code:

 import moment from 'moment'; var now = moment().format(); 

Limitations would be what it tries to “stretch” to the browser (which does not exist in this context). That's why polyfills stuff like XHR.

The official documentation contains examples of how to use the moments library

Answer 2

Some of the points work in React Native, while others do not. I suspect this is relevant to the audience.

I can use the moment to format:

 moment(new Date()).format("YYYY-MM-DD hh:mm:ss") 

But not for active formatting:

 moment(new Date()).format("YYYY-MM-DD hh:mm:ss").fromNow() 

Answer 3

It seems that right now, some npm modules are not compatible with the packer . In fact, I did not understand why else, but what I resort to is to have a provider folder and copy it through the web version, but at the top, specially placing

/** * @providesModule moment */

And at the bottom of it change:

module.exports = moment;

Not sure if this is the right way, but the packaging is still pretty new for everyone.

Answer 4

to use the npm library just use this command with the appropriate library name

 npm install moment --save 

for example.) npm install {your library name here} --save

then just import into your class and use

 import moment from 'moment';
