parse express app.js route

Question

如何基于all.js文件获取所有可用路由的列表？

Answer 1

You can dig around inside the app.routes object, which is an instance of Router . The easiest way would probably be to load up your app in an interactive listener and just take a look at the various objects contained in app.routes .

If you want to be more methodical, you can read the source for the router and route objects, eg https://github.com/visionmedia/express/blob/master/lib/router/route.js

Answer 2

There's actually a better way of doing this, TJ Holowaychuck (the author of Express) made a gist with it:

app.routes.all().forEach(function(route){
  console.log('  \033[90m%s \033[36m%s\033[0m', route.method.toUpperCase(), route.path);
});

Answer 3

for(var type in app.routes.routes) {
  console.log(type+":");
  for(var rts in app.routes.routes[type]) {
    console.log(app.routes.routes[type][rts]);
  }
}

Answer 4

The routes object has verbs as properties. You can iterate over them and construct a list of all routes, methods etc.

I created a Gist creating a self describing rest-api. I'm sure it can be improved but if you want you can see how I iterate over the routes object there.

Feedback is welcome on the Gist.
