node.js - Node js Express Framework

i trying use reg ex express route in node app. want route match path '/' or '/index.html' instead matches :(

here's route.

app.get(/\/(index.html)?/, function(req, res){     res.set('content-type', 'text/plain');     res.send('hello node!'); });

how can regular expression work?

try this:

app.get(/^\/(index\.html)?$/, function(req, res){   res.set('content-type', 'text/plain');   res.send('hello node!'); });

without $, following first / can still match, , index.html optional prefix. without ^, match /something/index.html.
