Catch express bodyParser error

Question

I want to catch the error from the bodyParser() middleware when I send a json object and it is invalid because I want to send a custom response instead of a generic 400 erro

Answer 1

what I did was just:

app.use(bodyParser.json({ limit: '10mb' }))
// body parser error catcher
app.use((err, req, res, next) => {
  if (err) {
    res.status(400).send('error parsing data')
  } else {
    next()
  }
})
