Share authentication and authorization code for central services

Registering this module with hapi with install an authentication scheme with the name 'basic'

Basic authentication requires validating a username and password combination. The 'basic' scheme takes the following options:

• validate - (required) a user lookup and password validation function with the signature function(request, username, password, callback) where:
  • request - is the hapi request object of the request which is being authenticated.
  • username - the username received from the client.
  • password - the password received from the client.
  • callback - a callback function with the signature function(err, isValid, credentials) where:
    • err - an internal error.
    • isValid - true if both the username was found and the password matched, otherwise false.
    • credentials - a credentials object passed back to the application in request.auth.credentials. Typically, credentials are only included when isValid is true, but there are cases when the application needs to know who tried to authenticate even when it fails (e.g. with authentication mode 'try').

        password: '$2a$10$iqJSHD.BGr0E2IxQwYgJmeP3NvhPrXAeLSaGCj6IR/XU5QtjVu5Tm',   // 'secret'
        name: 'John Doe',
        id: '2133d32a'
    }
};

const validate = function (request, username, password, callback) {

    const user = users[username];
    if (!user) {
        return callback(null, false);
    }

    Bcrypt.compare(password, user.password, (err, isValid) => {

        callback(err, isValid, { id: user.id, name: user.name });
    });
};

server.register(require('@@mojaloop/central-services-shared'))

server.auth.strategy('simple', 'basic', { validate: validate });
server.route({ method: 'GET', path: '/', config: { auth: 'simple' } });

We use npm-audit-resolver along with npm audit to check dependencies for vulnerabilities, and r

To start a new resolution process, run:

npm run audit:resolve

You can then check to see if the CI will pass based on the current dependencies with:

npm run audit:check

And commit the changed audit-resolv.json to ensure that CircleCI will build correctly.
