natours-backend's Issues

Add a debugger to debug NodeJS

Add a debugger tool to debug the NodeJs code

• Research for a debugging tool
• Implement the debugging tool decided

Create user roles

Create roles

• admins
• guides
• users

Email for dev mode

For sending emails in production, we use SendGrid which comes at a cost.
We need to implement something like Mailtrap or some other service to reduce the SendGrid usage in dev mode.

Create helper function to filter request

Problem

At places, we have the following:

This sends the whole request body to the model which can contain keys that we may not want to be changed from the request body.

Solution

We need to create a helper function/class that would provide the option to filter the values (only the ones we need).

Example

// Instead of
const tour = await Tour.create(req.body);

// To use
const filteredBody = filterFunction('name', 'date'); // this would return an object with the specified keys
const tour = await Tour.create(filteredBody);

Routes to get tours

Create routes for the following

• Get all tours
• Get a single tour

Delete tours

Provide ability to admins to be able to delete tours.

Filter tours

Create filtering for tours based on the following:

• Price
• Date
• Rating
• #22

Convert script file to use ESM syntax

The script file inside /scripts folder is currently a CJS module. However, we need to change it to use ESM modules.

Issue with logger

Describe the bug
Error log seems to not show completely instead shows text "error"

To Reproduce
Create any kind of error and log it using logger library.

Expected behavior
It should show a full error object.

Tour ratings

Provide forms for the user (who bought the tour) to leave a rating for that particular tour.

Create password less login functionality

Flow for the task:

1. Admins/guides come to the login page
2. They enter email
3. A login link is sent to their email
4. They click on the link and get logged in

Tour stats

Create routes to provide tour stats.

Login with password

Add feature to login with password for the users.

Filter tour by location

Filter a tour by its location.
Relates to - #9

Configure managing secret keys

Problem
Storing encryption keys in a .env file is generally not considered a secure practice. The .env file is typically used for storing configuration variables and should not be used to store sensitive information like encryption keys.

Solution
Configure HashiCorp vault in order to store the keys in a vault instead of a plain text file .env

Add route protection

We need to add middleware/functions for the routes. This will include:

• Add routes for logged in user
• Add route for admins

Email verification

Provide email verification for those who signup with email.

Send email functionality

Create a helper function/class that would allow us to send emails.

Tool to be used - SendGrid

Implement CORS

Implement cors to be able to send requests from clients to the server

• In the dev mode it should be able to receive requests from all sources
• In prod, have a whitelist for the allowed origins

Internationalization

Provide the ability to support multiple languages.

Location

Create a logging system

Currently, we use console.log() for error logging what we need is a more robust system for that.

1. We can use an email system to report critical errors
2. We can use a logging library eg. Winston, Bunyan for logging less critical errors

Change status value to boolean

In the application, where we want to set status for either response from 3rd party API or sending an answer from our server, we use 0 - failed and 1 - success.

it might be better to use a boolean instead of these status codes, as true & false are more evident.

Provide google auth for the application

New feature: Users are able to register/login with google.

Create a encryption helper

Need to create an encryption helper to encrypt/decrypt data transferred from/to the server.

Create a tour

Create a route for creating tours.

Tour guides

Add the ability to appoint or remove tour guides.

Send alert emails for errors

Send emails when unexpected things happen on the server.

• Create an email template for this.
• Send emails on errors
