I was trying Sails.js beta version (1.0.0-46) and noticed that flash messages are not available out-of-box:
req.flash(type, message)
I got a TypeError: req.flash is not a function message when trying to use it.
Ouch... just found the answer right in the upgrade docs (Upgrading to v1.0).
The connect-flash middleware has been removed (so req.flash() will no longer be available by default). If you wish to continue using req.flash(), run npm install --save connect-flash in your app folder and add the middleware manually.
Run the command bellow:
npm install --save connect-flash
And modify the config/http.js file:
middleware: {
flash : require('connect-flash')(),
order: [
'cookieParser',
'session',
'flash', // <-- add this
// 'bodyParser',
'compress',
'poweredBy',
'router',
'www',
'favicon',
],
