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).

npm run start 

or, if you have Sails globally:

sails lift 

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

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> 

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

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

request

{ "email": "email@example.com", "password": "abc123", "password_confirm": "abc123" }

response

{ "token": "<JWT>" }

request

{ "email": "email@example.com", "password": "abc123" }

response

{ "token": "<JWT>" }

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

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

response

{ "id": 1, "email": "email@example.com" }

Changes user password. User should be authorized.

request

{ "email": "email@example.com", "password": "abc123", "new_password": "xyz321", "new_password_confirm": "xyz321" }

response

{ "token": "<JWT>" }

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

Initiates procedure of password recovery.

request

{ "email": "email@example.com" }

response

{ "message": "Check your email" }

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

request

{ "email": "email@example.com", "reset_token": "<Password Reset Token>", "new_password": "xyz321", "new_password_confirm": "xyz321" }

response

{ "message": "Done" }

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.

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

npm run test
