Use require syntax for docs as an example instead of import

I would like to point out that while following the examples I faced following error : - In server.js import { newEnforcer } from 'casbin'; const enforcer = await newEnforcer('basic_model.conf', 'basic_policy.csv');

This is because nodejs natively supports require syntax and the index file of the librar is not in form of a module.

Adding "type": "module" in package.json (which parses every js file as a module) solves the issue but then messes with other packages like express.js

Additionally on declaring following const enforcer = await newEnforcer('basic_model.conf', 'basic_policy.csv') I got this error ;

Since this is casbin implementation for nodejs I would recommend to make example specific to node developers.

@hsluoyz In fact, I believe it should work as expected. I’m resolving problem.

@Zxilly what is import { newEnforcer } from 'casbin'; for? Browser? We should also provide the code for Node.js definitely.
