After calling res.send(), is there a need to call a return or somehow exit the callback function in order to make sure no further code executes? Like how when calling a header function in PHP, you need to call exit after that to prevent further code from being executed.
app.post('/create', function(req, res) {
if(req.headers['x-api-key'] === undefined) {
res.send({msg: "Goodbye"});
}
// other code that should only be processed if it has that header.
});
Just use return:
app.post('/create', function(req, res) {
if(req.headers['x-api-key'] === undefined)
return res.send({msg: "Goodbye"});
// other code that should only be processed if it has that header.
});
As per the node manual:
The method, response.end(), MUST be called on each response.
Use always next().
app.post('/create', function(req, res, next) {
if(req.headers['x-api-key'] === undefined) {
req.send({msg: "Goodbye"});
return next();
}
// other code that should only be processed if it has that header.
});
