reactjs

问题 I want to run two different js apps on my Nginx server. My problem is that I want to enable the React app on the main URL / on port 3000 and different js app on port 1337. When I set React App on the main URL it's working properly but any application on different URL like /admin that loads the second app it's not loaded properly. I have changed the paths and now I have my second app on main URL / and it's working properly but when I run React app on /admin URL it cannot load files properly.

But '=' is used instead of ':' means its not a name-value pair. So what is it? Also, what is the purpose of the assignment operator between two objects { route = '/', history = createHistory(createMemorySource(route)
