Passing error message to template through redirect in Express/Node.js

Question

In my Node.js application, I have a function (routed by Express) which presents a form to the user:

app.get(\'/register\', function (req, res) {
  res.render         


        

Answer 1

You need to use flash notifications, and it is built into express.

You'll add a message like so: req.flash("error", "Invalid form...");

You'll need a dynamic handler to add the messages to your rendered template, or you can check out the ones TJ has made for express. (express-messages)
