Expose empty object (representing no request body) as a constant

I should be able to do something along the lines of …

import bodyParser, {emptyBody} from 'body-parser';

app.use(bodyParser.raw({
  type: 'application/json'
}));

app.use((req, res) => {
  if (req.body === emptyBody) {
    // ...
  }
});

Otherwise, unless I am missing something, there is currently no safe way to check if the request body is empty.

Right, it is a breaking change, yes. 2.0 can come out at any point. The only reason it hasn’t come is that there was the strong desire to refactor the internals to support the generic parser case, which is very close to being done (finally!).

FWIW you can accurately detect the body with the additional import of the type-is module (which is already a dependency of this module) though require('type-is').hasBody export. That is the work-around I’m using within my own code base until 2.0.

I’m going to at least try and rebase the current 2.0 branch tonight and cut an alpha of it to npm to give it the proper push forward it needs at this point. This is just an aside, I’m not saying this would really help you in particular.

Yea, we could do that. Right now the 2.0 branch is going to just make req.body = undefined when there is no body. Is that possibly a solution here?
