Express - 400 Bad Request On Post And Put

I'd like some help as I'm new to Node.js and express. I have the following code which I'm testing on Postman const Joi = require('@hapi/joi'); const bodyParser = require('body-pars

Solution 1:

👨‍🏫 I've been test this code and I mean you can try this code below 👇:

app.post('/api/courses', (request, response) => {
  let { error } = validateCourse(request.body);

  if (error) {
      response.status(400).send(error.details[0].message); // *
  }

  let course = {
      id: courses.length + 1,
      name: request.body.name
  };

  // TODO saveconsole.log('TODO save the record');

  response.send(course);
});

app.put('/api/courses/:id', (request, response) => {
  let course = courses.find(c => c.id === parseInt(request.params.id));

  if(!course) response.status(404).send('Oops!');

  let { error } = validateCourse(request.body);

  if (error) {
      response.status(400).send(error.details[0].message);
  }

  // TODO saveconsole.log('TODO save the record');

  response.send(course);
});


functionvalidateCourse(course) {
  let schema = Joi.object({
      name: Joi.string().min(4).required()
  });
  console.log(course);
  return schema.validate(course);
}

I hope it's can help you 🙏.

Solution 2:

let course = courses.find(c => c.id === parseInt(request.params.id))
if(!course) return response.status(404).send('Oops!');

let { error } = validateCourse(request.body);
if (error) {
    return response.status(400).send(error.details[0].message);
}

response.send(course);

This must resolve the error that you are getting on PUT request.
