Simplify JWT Authentication in Express.js with tokenease

Express JWT Library tokenease

===================

This library provides easy-to-use functions for handling JWT (JSON Web Token) authentication in Express.js applications. It simplifies token authentication, generation, refreshing, and revocation, making it more convenient for developers to implement JWT-based authentication in their projects.

Installation

To use this library, you need to install it via npm:

npm install tokenease

Usage

Below are the functions provided by this library:

authenticateToken(secretKey)

Middleware function to authenticate JWT tokens.

• secretKey: The secret key used to verify JWT tokens.

   const { authenticateToken } = require('tokenease');
  

  app.use(authenticateToken('your_secret_key'));

generateToken(payload, secretKey, expiresIn = '1h')

Function to generate a JWT token.

• payload: Data to be included in the token.
• secretKey: The secret key used to sign the token.

• expiresIn: Expiry duration for the token (default is 1 hour).

   const { generateToken } = require('tokenease');
  
   const token = generateToken({ userId: '123456' }, 'your_secret_key');
  

refreshAccessToken(refreshToken, secretKey, extractUser)

Function to generate a new access token using a refresh token.

• refreshToken: The refresh token used to generate a new access token.
• secretKey: The secret key used to verify tokens.

• extractUser: Function to extract user data from the refresh token.

   const { refreshAccessToken } = require('tokenease');
  
  refreshAccessToken(refreshToken, 'your_secret_key', (decoded) => decoded.user);
  

blacklistToken(tokenIdentifier, schemaClass)

Function to revoke or blacklist a token.

• tokenIdentifier: Identifier of the token to be blacklisted.

• schemaClass: Schema class for interacting with the database.

   const { blacklistToken } = require('tokenease');
  
   blacklistToken(tokenIdentifier, YourSchemaClass)
   .then((success) => {
  console.log('Token blacklisted:', success);
  })
  .catch((error) => {
  console.error('Error blacklisting token:', error);
  });
  

revokeUserTokens(userId, schemaClass)

Function to revoke all tokens associated with a user.

• userId: ID of the user whose tokens need to be revoked.

• schemaClass: Schema class for interacting with the database.

   const { revokeUserTokens } = require('tokenease');
  
  revokeUserTokens(userId, YourSchemaClass)
  .then((success) => {
   console.log('Tokens revoked:', success);
  })
  .catch((error) => {
  console.error('Error revoking tokens:', error);
  });
  

revokeTokenByIdentifier(tokenIdentifier, schemaClass)

Function to revoke a specific token by its identifier.

• tokenIdentifier: Identifier of the token to be revoked.

• schemaClass: Schema class for interacting with the database.

   const { revokeTokenByIdentifier } = require('tokenease');
   revokeTokenByIdentifier(tokenIdentifier, YourSchemaClass).then((success) => {
   console.log('Token revoked:', success);
  })
  .catch((error) => {
  console.error('Error revoking token:', error);
  });
  

handleTokenExpiry(accessToken, refreshToken, secretKey, extractUser)

Function to handle token expiry by refreshing access tokens using refresh tokens.

• accessToken: The access token to be verified.
• refreshToken: The refresh token used to refresh the access token.
• secretKey: The secret key used to verify tokens.

• extractUser: Function to extract user data from the refresh token.

   const { handleTokenExpiry } = require('tokenease');
  
  handleTokenExpiry(accessToken, refreshToken, 'your_secret_key', (decoded) => decoded.user)
  .then((newAccessToken) => {
  console.log('New access token:', newAccessToken);
  }).catch((error) => {
  console.error('Error handling token expiry:', error);
  });
