thomasyip / CORS_ExpressJS
Created March 20, 2013 08:22
Cheatsheet for adding CORS supports to an ExpressJS app. I found that the most reliable way of sending CORS headers is to echo back what the browser sent to the server. Reminder to test it with browser cache disable and cleared at least one.
// CORS
app.use(function(req, res, next) {
if ('OPTIONS' !== req.method) {
if ('origin' in req.headers) {
res.setHeader('Access-Control-Allow-Origin', req.headers.origin);
}
next();
} else {
var body = '{}\n';
if ('origin' in req.headers) {
