Updating a contact

The update route will update an existing contact with new details. We can achieve this by getting the required id as a route parameter, along with the updated content from the request body, then using the mongoose .findByIdAndUpdate() method to update the specified contact. The route will return the updated contact as a response on a successful update:

// ./controllers/ContactController.js// ...module.exports = {  async index(ctx) {    const contacts = await Contact.find();    ctx.body = {      status: 'success',      data: contacts    };  },  async store(ctx) {    const { body } = ctx.request;    let contact = new Contact(body);    contact = await contact.save();    ctx.body = {      status: 'success',      data: contact    };  },  async show(ctx) { const { id } = ctx.params; ...
