Here is an example of update code using mongodb. But this same logic can be used for relational databases.
usuario.routejs.
const router = require('express').Router();
const userController = require('../controllers/user.controller');
//...
router.put('/users/:id', userController.updateUserbyId);
//...
module.exports = router;
usuario.controller.js
exports.updateUserbyId = (req, res) => {
const options = { returnOriginal: false };
db.get().collection('user').findOneAndUpdate({_id: ObjectId(req.params.id)}, {$set: {"name": req.body.name }}, options).then((result) => {
if (result.value === null) {
return res.status(404).json({ errors: [{location: "users", msg: "Not found", param: req.params.id}]})
}
res.status(200).json(result.value);
}).catch((err) => {
res.status(500).json({errors: [{location: "users", msg: err, param: req.params.id}]})
})
}
I also recommend validating the entry before entering the database.
