JSON Web Token authorization API

Based on Sails.js (v0.12)

An example implementation of JWT-based API for user registration and authorization.

It supports:

1. User register;
2. User login;
3. Getting account info;
4. Token generation and validation;
5. Password reset (with a reset token);
6. Password change (with JWT credentials);
7. Account locking.

Things to do:

1. Optional email notifications (based on environment);
2. Keep reset token encrypted and with a validity date;
3. Unlock after some freeze period;
4. Registration confirmation (with a confirm token).

Russian description / Русское описание

Start

npm run start

or, if you have Sails globally:

sails lift

For security reasons, please change JWT_SECRET in api/config/env/development.js.

Pass JWT

Token-free endpoints:

/user/create
/user/login
/user/forgot
/user/reset_password

Token-required endpoints:

/user
/user/change_password 

To pass a JWT use Authorization header:

Authorization: Bearer <JWT>

API methods description

For some reasons I do not use REST. Shortcuts also disabled by default (see api/config/blueprints.js).

POST /user/create

Creates a new user. Requirements for the password: length is 6-24, use letters and digits.

request

{
  "email": "[email protected]",
  "password": "abc123",
  "password_confirm": "abc123"
}

response

{
  "token": "<JWT>"
}

POST /user/login

request

{
  "email": "[email protected]",
  "password": "abc123"
}

response

{
  "token": "<JWT>"
}

N.B. Account will be blocked after 5 fails in 2 mins (configurable in api/services/UserManager.js).

GET /user

Returns basic info about current account. Requires authorization.
request Params not required.

response

{
  "id": 1,
  "email": "[email protected]"
}

POST /user/change_password

Changes user password. User should be authorized.

request

{
  "email": "[email protected]",
  "password": "abc123", 
  "new_password": "xyz321",
  "new_password_confirm": "xyz321"
}

response

{
  "token": "<JWT>"
}

N.B. All old tokens will be invalid after changing password.

POST /user/forgot

Initiates procedure of password recovery.

request

{
  "email": "[email protected]"
}

response

{
  "message": "Check your email"
}

POST /user/reset_password

Reset password to a new one with a reset token. Reset token sends to a user after /user/forgot.

request

{
  "email": "[email protected]",
  "reset_token": "<Password Reset Token>",
  "new_password": "xyz321",
  "new_password_confirm": "xyz321"
}

response

{
  "message": "Done"
}

HTTP codes

All endpoints uses HTTP status codes to notify about execution results

• 200 ok, reqeust executed successfully;
• 201 created, new user created successfully;
• 400 bad request, usually means wrong params;
• 403 forbidden, for locked accounts;
• 500 server error, something went wrong.

Tests

The project uses Travis-CI and Coveralls integration and has some tests. Run it via:

npm run test
