Best practices regarding unknown properties

See original GitHub issue

Requests can be validated via a custom schema, e.g.

req.checkBody({
  email: { ...
});

which is great. Are there any guidelines what to do, if the request should only contain the email property and nothing else? For example the following request body should cause validation to fail

{
  "email": "example@example.org",
  "extra": "I should not be here!"
}

with an error message along the lines of Unknown property "extra".

Any thoughts / hints appreciated! 😃

Nice, thanks for the reference! 👍 that’s pretty much my use case actually, the solution with lodash

var requestParams = _.pick(req.body, _.keys(validationMap));

pretty much solves my problem! 🎉

Primary difference to this issue is that, rejecting unknown properties in a request could help potential client API developers. I’ll keep this open as a reference 📘
