v0.6.0 Migration

Both mxins have been replaced by middlewares.

`moleculer.config.js`

Require the middlewares and add them to the middlewares array. Take care of the order, the authentication middleware must be called before the authorization middleware. Which means that the authentication middleware must be after the authorization middleware in the array. This because the middleware are called in the reverse order.

+const AuthorizationMiddleware = require('@voilab/vmol-auth').Authorization;
+const AuthenticationMiddleware = require('@voilab/vmol-auth').Authentication;

module.exports = {
    // Register custom middlewares
    middlewares: [
+        AuthorizationMiddleware({
+            userRolesAction: 'myservice.getRolesForUser',
+            userRolesActionSecret: process.env.MY_ACTION_SECRET
+        }),
+        AuthenticationMiddleware({
+            userJWTParamsAction: 'myservice.getJWTParamsPublic'
+        })
    ]
}

Services

The old mixins must be removed from the services.

-const { AuthorizationMixin, AuthenticationMixin } = require('@voilab/vmol-auth');
-
module.exports = {
    name: 'myservice',

-    mixins: [AuthorizationMixin, AuthenticationMixin],
-
    settings: {
        foo: 'bar',
-        auth: {
-            tokenService: 'authservice',
-            abilityService: 'authservice'
-        }
    },

    /**
     * Actions
     */
    actions: {}
};

Public actions

Actions that does not require authentication and/or authorization need the disableAuthentication and/or disableAuthorization options.

module.exports = {
    name: 'myservice',

    settings: {
        foo: 'bar'
    },

    actions: {
        publicAction: {
            disableAuthentication: true,
            disableAuthorization: true,

            handler(ctx) {
                return 'Hello world!';
            }
        }
    }
};
