koa-authz's Issues

Question: how can I use customized authorizer ?

maybe a stupid question here...
I got error when I tried to extends BasicAuthorizer as below:

const BasicAuthorizer = require("koa-authz").BasicAuthorizer;
.........
// use CustomizeAuthorizer
class CustomizeAuthorizer extends BasicAuthorizer {
........
}

Error like below:

class CustomizeAuthorizer extends BasicAuthorizer {
                                  ^
TypeError: Class extends value undefined is not a constructor or null
........

how can I import BasicAuthorizer into my app.js??

npm having the same version ??

I got koa-authz from npm with version 1.0.0, but seems it doesn't have the same content from the git(koa-authz)..

Package is problematic on npm

On the master branch if (!await authzorizer.checkPermission()) { ctx.status = 403 return }
On the v2.0 if (!await authzorizer.checkPermission()) { ctx.status = 403 }
I install [email protected] and it like v2.0

No permission need return
