How do I set a MIME type before sending a file in Node.js?
I figured it out!
Thanks to @rdrey's link and this node module I managed to correctly set the MIME type of the response, like this:
function handler(req, res) { var url = convertURL(req.url); if (okURL(url)) { fs.readFile(url, function(err, data) { if (err) { res.writeHead(404); return res.end("File not found."); } res.setHeader("Content-Type", mime.lookup(url)); //Solution! res.writeHead(200); res.end(data); }); } else { res.writeHead(403); return res.end("Forbidden."); }}
Search google for the Content-Type HTTP header.
Then figure out how to set it with http://expressjs.com/api.html#res.set
Oops, the example includes your answer ;)
Simply check the file ending, if it's .js, set the appropriate MIME type to make browsers happy.
EDIT: In case this is pure node, without express, look here: http://nodejs.org/api/http.html#http_response_setheader_name_value
mime.lookup() is now renamed to mime.getType().So you can do like this:
res.set('Content-Type', mime.getType('path/file'));
