What is the smartest way to handle robots.txt in Express?
Use a middleware function. This way the robots.txt will be handled before any session, cookieParser, etc: app.use(‘/robots.txt’, function (req, res, next) { res.type(‘text/plain’) res.send(“User-agent: *\nDisallow: /”); }); With express 4 app.get now gets handled in the order it appears so you can just use that: app.get(‘/robots.txt’, function (req, res) { res.type(‘text/plain’); res.send(“User-agent: *\nDisallow: /”); });
