Unable to resolve module 'events'
After requiring this package as per the instructions, I am getting:
Unable to resolve module 'events' from '/Users/myName/AwesomeProject/node_modules: Module does not exist in the module map ...
Just installed using npm, getting the same error.
Edit: Resolved after npm install events and timers, but I think those two should be listed as dependencies for xml2js?
i have the same problem with angular2, i did this:
npm install @types/xml2js --save-dev npm install xml2js --save-dev npm install events --save-dev
then i can build, but i not tested if it'w work. Why i8wu you need timers ?

I don't know much about React-Native but it looks like it does not offer a Node.js environment?
The only non-Node dependencies that we currently have is sax and xmlbuilder (though I plan to reduce that too) so I am surprised it would miss modules which are in the Node Stdlib.
I also tried to use the xml2js in a my react-native app and I had similar issues. The solution was to install all required xml2js dependencies in my react-native app.
cd myReactNativeApp
npm install events buffer stream timers --save

Adding events, stream and timers dependency worked for me in a react-native app.
yarn add events stream timers
or
npm install events stream timers --save
Its built entirely on top of Node. What makes you question it?
It failed because the native React runtime does not include the Node standard library. Read more at https://docs.expo.io/workflow/using-libraries/#using-third-party-libraries
I am using [email protected] with [email protected] and needed to add these libs manually:
yarn add buffer events stream timers
Added this addtionally:
yarn add @types/xml2js -D
