Requesting node modules from some proxy object;
npm install koa-r
var r = require('koa-r').isGlobal(true);
r.set('someModule', require('path/to/someModule'));
// etc...
// and then when you need to call some function from loaded module
r('someModule', 'someFn')();
As you can see we need to specify key and value for some module, and after that we can access
to loaded module from some other place. Note that if isGlobal option is setted to true,
we don't need to require koa-r twice. We need to require it only once, and after that it will in GLOBAL.r variable.
I am using this module in combination with koa-router.
My idea is to separate routes definitions into multiple files, and then from one central place to mount routes to some url paths. Before that we set to koa-r all required dependencies for executing route callbacks, so we can call easily functions which are handling some routes. Example:
// some/path/handlers/user.js
exports.getUsers = function * (next) {
// some code here...
yield next;
}
// some/path/router/index.js
var mount = require('koa-mount'),
r = require('koa-r').isGlobal(true),
userAPI = require('some/path/router/user.js');
r.set('user', require('/some/path/handlers/user'));
// etc...
module.exports = function (app) {
app.use(mount('/api/user/', userAPI.middleware()));
// etc...
};
// some/path/router/user.js
var Router = require('koa-router'),
api = new Router();
api.get('/users', r('user', 'getUsers'));
module.exports = api;
When user visits api/user/users url, function getUsers from user module will handle this route.
