create jwt token code example

Example 1: generate jwt secret key

node -e "console.log(require('crypto').randomBytes(256).toString('base64'));"

Example 2: add expiry to jwt extended token

@jwt_required
def create_dev_token():
    username = get_jwt_identity()
    expires = datetime.timedelta(days=365)
    token = create_access_token(username, expires_delta=expires)
    return jsonify({'token': token}), 201

Example 3: jwt generate token

const genToken = (id) => {
  return JWT.sign({ id }, process.env.JWT_SECRET)
}

Example 4: jwt encode

jwt.encode( { 'client_id':'value', 'expires_in':'datetime'}, SECRET_KEY, algorithm='HS256' )

OBS:
Convert datetime to string because in the backend is a json encode system 
and it will generate a TypeError
ex: TypeError: Object of type datetime is not JSON serializable

Example 5: jwt

JSON Web Token is an Internet standard for creating data with optional
signature and/or optional encryption whose payload holds JSON that asserts
some number of claims.

The tokens are signed either using a private secret or a public/private key.
