What does Connect.js methodOverride do?

Question

The Connect.js very terse documentation says methodOverride

Provides faux HTTP method support.

What does that mean?

Answer 1

• If you want to simulate DELETE and PUT, methodOverride is for that.
• If you pass in the _method post parameter set to 'delete' or 'put', then you can use app.delete and app.put in Express instead of using app.post all the time (thus more descriptive, verbose):

Backend:

// the app
app.put('/users/:id', function (req, res, next) {
  // edit your user here
});

Client logic:

// client side must be..
<form> ...
  <input type="hidden" name="_method" value="put" />
</form>
