text(req, res, cb)

Converts request body to string.

urlencoded(req, res, cb)

Parses request body using querystring.parse.

json(req, res, cb)

Parses request body using JSON.parse.

custom(fn)(req, res, cb)

Custom function for parsec.

// curl -d "this text must be uppercased" localhost
await custom(
  req,
  (d) => d.toUpperCase(),
  (err) => {}
)
res.end(req.body) // "THIS TEXT MUST BE UPPERCASED"
