## API Documentation
To view the list of available APIs and their specifications, run the server and go to `http://localhost:3000/v1/docs` in your browser. This documentation page is automatically generated using the [swagger](https://swagger.io/) definitions written as comments in the route files.
### API Endpoints
List of available routes:
**Auth routes**:\
`POST /v1/auth/register` - register\
`POST /v1/auth/login` - login\
`POST /v1/auth/refresh-tokens` - refresh auth tokens\
`POST /v1/auth/forgot-password` - send reset password email\
`POST /v1/auth/reset-password` - reset password\
`POST /v1/auth/send-verification-email` - send verification email\
`POST /v1/auth/verify-email` - verify email
**User routes**:\
`POST /v1/users` - create a user\
`GET /v1/users` - get all users\
`GET /v1/users/:userId` - get user\
`PATCH /v1/users/:userId` - update user\
`DELETE /v1/users/:userId` - delete user
## Error Handling
The app has a centralized error handling mechanism.
Controllers should try to catch the errors and forward them to the error handling middleware (by calling `next(error)`). For convenience, you can also wrap the controller inside the catchAsync utility wrapper, which forwards the error.
```javascript
const catchAsync = require('@/utils/catchAsync');
const controller = catchAsync(async (req, res) => {
// this error will be forwarded to the error handling middleware
throw new Error('Something wrong happened');
});
```
The error handling middleware sends an error response, which has the following format:
```json
{
"code": 404,
"message": "Not found"
}
```
When running in development mode, the error response also contains the error stack.
The app has a utility ApiError class to which you can attach a response code and a message, and then throw it from anywhere (catchAsync will catch it).
For example, if you are trying to get a user from the DB who is not found, and you want to send a 404 error, the code should look something like:
```javascript
const httpStatus = require('http-status');
const ApiError = require('@/utils/ApiError');
const User = require('@/models/User');
const getUser = async (userId) => {
const user = await User.findById(userId);
if (!user) {
throw new ApiError(httpStatus.NOT_FOUND, 'User not found');
}
};
```
## Validation
Request data is validated using [Joi](https://joi.dev/). Check the [documentation](https://joi.dev/api/) for more details on how to write Joi validation schemas.
The validation schemas are defined in the `src/validations` directory and are used in the routes by providing them as parameters to the `validate` middleware.
```javascript
const express = require('express');
const validate = require('@/middlewares/validate');
const userValidation = require('@/validations/user.validation');
const userController = require('@/controllers/user.controller');
const router = express.Router();
router.post('/users', validate(userValidation.createUser), userController.createUser);
```
## Authentication
To require authentication for certain routes, you can use the `auth` middleware.
```javascript
const express = require('express');
const auth = require('@/middlewares/auth');
const userController = require('@/controllers/user.controller');
const router = express.Router();
router.post('/users', auth(), userController.createUser);
```
These routes require a valid JWT access token in the Authorization request header using the Bearer schema. If the request does not contain a valid access token, an Unauthorized (401) error is thrown.
**Generating Access Tokens**:
An access token can be generated by making a successful call to the register (`POST /v1/auth/register`) or login (`POST /v1/auth/login`) endpoints. The response of these endpoints also contains refresh tokens (explained below).
An access token is valid for 30 minutes. You can modify this expiration time by changing the `JWT_ACCESS_EXPIRATION_MINUTES` environment variable in the .env file.
**Refreshing Access Tokens**:
After the access token expires, a new access token can be generated, by making a call to the refresh token endpoint (`POST /v1/auth/refresh-tokens`) and sending along a valid refresh token in the request body. This call returns a new access token and a new refresh token.
A refresh token is valid for 30 days. You can modify this expiration time by changing the `JWT_REFRESH_EXPIRATION_DAYS` environment variable in the .env file.
## Authorization
The `auth` middleware can also be used to require certain rights/permissions to access a route.
```javascript
const express = require('express');
const auth = require('@/middlewares/auth');
const userController = require('@/controllers/user.controller');
const router = express.Router();
router.post('/users', auth('manageUsers'), userController.createUser);
```
In the example above, an authenticated user can access this route only if that user has the `manageUsers` permission.
The permissions are role-based. You can view the permissions/rights of each role in the `src/config/roles.js` file.
If the user making the request does not have the required permissions to access this route, a Forbidden (403) error is thrown.
## Logging
Import the logger from `src/config/logger.js`. It is using the [Winston](https://github.com/winstonjs/winston) logging library.
Logging should be done according to the following severity levels (ascending order from most important to least important):
```javascript
const logger = require('/config/logger');
logger.error('message'); // level 0
logger.warn('message'); // level 1
logger.info('message'); // level 2
logger.http('message'); // level 3
logger.verbose('message'); // level 4
logger.debug('message'); // level 5
```
In development mode, log messages of all severity levels will be printed to the console.
In production mode, only `info`, `warn`, and `error` logs will be printed to the console.\
It is up to the server (or process manager) to actually read them from the console and store them in log files.\
This app uses pm2 in production mode, which is already configured to store the logs in log files.
Note: API request information (request url, response code, timestamp, etc.) are also automatically logged (using [morgan](https://github.com/expressjs/morgan)).
## Linting
Linting is done using [ESLint](https://eslint.org/) and [Prettier](https://prettier.io).
In this app, ESLint is configured to follow the [Airbnb JavaScript style guide](https://github.com/airbnb/javascript/tree/master/packages/eslint-config-airbnb-base) with some modifications. It also extends [eslint-config-prettier](https://github.com/prettier/eslint-config-prettier) to turn off all rules that are unnecessary or might conflict with Prettier.
To modify the ESLint configuration, update the `.eslintrc.json` file. To modify the Prettier configuration, update the `.prettierrc.json` file.
To prevent a certain file or directory from being linted, add it to `.eslintignore` and `.prettierignore`.
To maintain a consistent coding style across different IDEs, the project contains `.editorconfig`
