app.use
app.get
の前に記述する必要があります 。 app.get
Expressによって最初に呼び出されます。
var mongo = require('mongodb');
var monk = require('monk');
var db = monk('localhost:27017/notepad');
var app = express();
// mongoDB
// Do all your "pre-route" use() functions first
app.use(function (req, res, next) {
req.locals.db = db; // this is setting up db property to request
next();
});
app.get('/users', routes.userlist);
あなたのルートで...
var db = req.locals.db; // Instead of req.db
またはさらに良い...
var mongo = require('mongodb');
var monk = require('monk');
var db = monk('localhost:27017/notepad');
var app = express();
app.locals.db = db;
app.get('/users', routes.userlist); // Access it using req.locals.db
