reactjs

问题 I'm using "react-router-dom": "^4.2.2" . If I test on localhost:3000/second it works perfectly. When I upload this on ubuntu server with nginx and I try www.website.com , it works .

问题 Let's say I have 5 jsx files and each file uses some config parameter. My index.js file imports all of these 5 jsx files. Instead of having my config data spread accross 5 files, is there a way for my jsx files to get the data from a global JS object which has loaded the data from a config file?

问题 I want to make a border image to a View , similar to border-image in the css.
