When asked to install vue-router, accept the option, because we need vue-router for this application.
Links v-link replaced The v-link directive has been replaced with a new , as this sort of job is now solely the responsibility of components in Vue 2. Esto sería todo: Vamos ahora con los componentes. Next you would want your main app to know router exists, so declare it inside the main app declaration. Cuando vemos muchas carpetas y archivos nos intimidamos, pero tranquilo.
Routing - For example: if route. When asked to install vue-router, accept the option, because we need vue-router for this application.
Coupled with , we can build high performance applications with complete dynamic routes. Vue-router is an efficient tool and can handle authentication in our Vue application seamlessly. In this tutorial, we will look at using vue-router to handle authentication and access control for different parts of our application. If you are not sure of an option, simply click the return key enter key to continue with the default option. When asked to install vue-router, accept the option, because we need vue-router for this application. We will use to hash all our passwords. For this, we will use. Create a new directory named server. This is where we will store everything we will use to make our node backend. In the server directory, create a file and save it as app. Let's define the route for registering a new user: router. First, we pass the request body to a database method which we will define later , and pass a callback function that to handle the response from the database operation. As expected, we have defined error checks to ensure we provide accurate information ot users. When a user is successfully registered, we select the user data by email and create an authentication token for the user with the jwt package we had imported earlier. We use a secret key in our config file which we will create later to sign the auth credentials. This way, we can verify a token sent to our server and a user cannot fake an identity. Now, define the route for registering an administrator and logging in, which are similar to register: router. If they are the same, we log the user in. If not, well, feel free to respond to the user how you please. Now, let's use the express server to make our application accessible: app. If you find any of the above confusing, you can take an on Node. Database file ; this. You may want to use more generic and reusable methods here for database operations and likely use a promise to make it more efficient. This will allow you have a repository you can use with all other classes you define especially if your application uses MVC architecture and has controllers. Updating The Vue-router File The vue-router file can be found in. This is different from what we did with our server and should not be confused. We will create the components below. In our case above, we have defined some routes as guest which means only users not authenticated should see it , some to require authentication which means only authenticated users should see it and the last one to be only accessible to admin users. Now, let's handle requests to these routes based on the meta specification: router. This is where we can define our checking condition and restrict user access. The method takes three parameters — to, from and next. Our check is on the to object. We use the name of the route to redirect, so check to be sure you are using this for your application. IMPORTANT: Always ensure you have next called at the end of every condition you are checking. This is to prevent your application from failing in the event that there is a condition you forgot to check. We made a request to the server to authenticate the credentials the user supplies. Of course, we redirect the user to whichever part of our application they tried to access before being redirected to login. If they came to login directory, we redirect them based on the user type. If you are not familiar with composing vue components, you can take this course. Next, create a Register. It creates the register component and accompanying method to handle user submission of the registration form. Now, create the file Admin. Finally, create the file UserBoard. Setting Up Axios Globally For all our server requests, we will use. Axios is a promise based HTTP client for the browser and node. We can now use axios in all our components like this. Running The Application Now that we are done with the application, we need to build all our assets and run it. Because we have a node js server along with our vue application, we will be both of them for our application to work. You can open the link it shows you to see the application Conclusion In this guide, we have seen how to use vue-router to define checks on our routes and prevent users from accessing certain routes. We also saw how to redirect users to different parts of our application based on the authentication state. We also built a mini server with Node. What we did is an example of how access control is designed in frameworks like Laravel. You can checkout out and see what other cool things you can do with it.
