Environment Variables

The following environment variables are required for the @coconut-packages/jsonwebtoken utility:

• JWT_SECRET: A secret key used for signing and verifying tokens.
• JWT_EXPIRATION: The expiration time for the tokens (e.g., 1h, 2d).
• JWT_ISSUER: The issuer of the token, typically your application name.
• JWT_AUDIENCE: The audience for the token, usually the intended recipients.

Ensure these variables are set in your environment before using the utility.

Example Code

Here is an example of how to use the @coconut-packages/jsonwebtoken utility:

const jwt = require('@coconut-packages/jsonwebtoken');

// Environment variables (ensure these are set in your environment)
const secret = process.env.JWT_SECRET;
const expiration = process.env.JWT_EXPIRATION;
const issuer = process.env.JWT_ISSUER;
const audience = process.env.JWT_AUDIENCE;

// Payload for the token
const payload = {
    userId: '12345',
    username: 'exampleUser'
};

// Sign a token
const token = jwt.sign(payload, secret, {
    expiresIn: expiration,
    issuer: issuer,
    audience: audience
});

console.log('Generated Token:', token);

// Verify a token
try {
    const decoded = jwt.verify(token, secret, {
        issuer: issuer,
        audience: audience
    });
    console.log('Decoded Token:', decoded);
} catch (err) {
    console.error('Token verification failed:', err);
}
