Vue.js JWT Authentication with Vuex and Vue Router

I will show you:. You can take a look at following flow to have an overview of Requests and Responses Vue Client will make or receive.

ROUTING SETUP - VueJS - Learning the Basics

Then the navbar now can display based on the state. App component also passes state to its child components. In these components, we use user.

After the installation is done, you can check dependencies in package. We also have methods for retrieving data from server. It checks Local Storage for user item. Otherwise, return an empty object. Note: For Node. You can see that we add a HTTP header with the help of authHeader function when requesting authorized resource.

To make code clear and easy to read, we define the User model first. Instead of using axios or AuthService directly, these Components should work with Vuex Store: — getting status with this. We use VeeValidate 2. If there is an invalid field, we show the error message. We check user logged in status using Vuex Store: this. If the status is truewe use Vue Router to direct user to Profile Page :. If the login is successful, go to Profile Pageotherwise, show error message.

This page gets current User from Vuex Store and show information. If the User is not logged in, it directs to Login Page. This is the root container for our application that contains navigation bar. We will add router-view here. Our navbar looks more professional when using font-awesome-icon. If you want to check Authorized status everytime a navigating action is trigger, just add router.

I hope you understand the overall layers of our Vue application, and apply it in your project at ease. You can find the complete source code for this tutorial on Github. Thank you for your comment. Hi Bezkoder, thanks for sharing this vue authentication project.

Hey Bezkoder, nice Project and really helpfull. Would it be possible to upload the sourcecode to github?You can therefore call this. To navigate to a different URL, use router. This method pushes a new entry into the history stack, so when the user clicks the browser back button they will be taken to the previous URL. Note : params are ignored if a path is provided, which is not the case for queryas shown in the example above. Instead, you need to provide the name of the route or manually specify the whole path with any parameter:.

These callbacks will be called when the navigation either successfully completed after all async hooks are resolvedor aborted navigated to the same route, or to a different route before current navigation has finishedrespectively.

Note: If the destination is the same as the current route and only params are changing e. It acts like router. This method takes a single integer as parameter that indicates by how many steps to go forwards or go backwards in the history stack, similar to window. You may have noticed that router. It is worth mentioning that Vue Router navigation methods pushreplacego work consistently in all router modes historyhash and abstract.

My understanding is that the whole discussion in is centered around error handling. My use-case does not involve any error-generating code path. Here is where the abort is triggered in confirmTransition :. I understood your comment in comment as telling me that my issue was separate from I spent quite some time debugging, researching and reproducing this in a minimal test case and I honestly thought this issue was different from the others linked.

Note also that, in an attempt to not add noise to the repo, my first step was to find another related issue and not hastily create a new one :. Of course all these issues are related to Promise rejection so maybe they will all be fixed the same way.

Coupled with vue-routerwe can build high performance applications with complete dynamic routes. Vue-router is an efficient tool and can efficiently handle authentication in our Vue application.

In this tutorial, we will look at using vue-router to handle authentication and access control for different parts of our Vue.

Follow the setup prompt and complete the installation of this application. If you are not sure of an option, 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. Next, we will set up a Node. For our Node. Because we are dealing with passwords, we need a way to hash passwords.

We will use bcrypt to hash all our passwords. Run the following command to install it:. We also want a way to confirm the users we authenticate when they try to make a request to a secured part of our application. For this, we will use JWT. Run the following command to install the JWT package we will use:. To read json data, we will send to our server, we need body-parser.

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. Add the following to it:. We have required all the packages we need for our application, defined the database, and created an Express server and router. Many people would use a CORS package here, but we do not have any complicated configurations, so this is fine.When building a modern web application, being able to navigate between pages is a necessity.

Not to mention it is very important to be able to do so easily. Each possible point of navigation, or page, is a route with its own configuration. While being a completely different framework, some of the concepts carry over to Vue. Go ahead and rename that file from HelloWorld.

This name will be important when we configure the router. Our second route will more or less be the same as our first because we like to keep our examples simple. Nothing complicated has been added or changed that is different from the initial scaffold. Each of these components will be a route in our application, so they must be added to the routes array of our new router.

Instead of setting Page1 as our default route, the logical choice is to redirect to it when the application loads at the root. Each route in the array receives a patha nameand a matching component. The path is what shows in the URL bar and future navigation can happen either based on the path or the name. Now we can worry about navigation within the application. We have two components and two possible routes so it makes sense to navigate back and forth between them. Navigation can happen via markup or via JavaScript.

If you wanted to navigate based on the route name, the tag could easily be changed to the following:. With it, we can create a method called navigate that will push a new navigation item into the stack. We need something to call this navigate method. This means that even though we navigated to Page1 from Page2we actually navigated to Page1rather than back to Page1.

This can be corrected by changing our navigate method to the following:. You just saw how to configure and navigate between routes using the vue-router library in a Vue.You can learn more about Vue. Routing is one of those methods. It allows the user to switch between pages without refreshing the page. This is what makes navigation easy and really nice in your web applications.

We need to have Node. We will be using vue-cli to generate a new Vue. Follow the steps given below:. Open the app in your text editor.

Inside the components folder, open the HellowWorld. We are now going to add a Bootswatch template. You can choose any template you like. Paste this code into App. Inside the components folder, create new file, name it blog. If you want to do the same thing for the service and contact component, you must have these files in your component folder:.

Now after creating these four components, we need to configure the routers so that we can navigate between the components. We need to learn the rules of routing. Now, we have to do some modifications inside the router folder, so open index.

If you have installed Vue with vue-cli, you will have the vue-router module imported by default. In our example, we set the home page as the default page. Now, when you open the the project in the browser, the first page that will appear is the home page. The vue-router has more advanced parameters and methods, but we are not jumping into this section at this point. Now we are going to set up the navigation through the Navbar that we created using the router-link element.

We will di scuss rout e-view in the next part when we use the animation transition. At this point, we will use parameters to navigate to specific components.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

How to use routing in Vue.js to create a better user experience

I have the problem of when I want to do a search multiple times it shows me the NavigationDuplicated error. My search is in the navbar and the way I have configured the search is to take the value using a model and then pass the value as a parameter to the ContentSearched component, and then receive the value of the search in that components.

I know the right way is to use a emitter, but I still don't know how to learn to use it. To access the emit is context. This happened to me when I had a router-link pointing to the same route. You can learn more on the github issue.

However, if you don't want to have a catch block which does nothing, in order to solve the issue you can compare the router navigation with the current route and only navigate if they differ:. See The Route Object for more info.

I think the best solution to this can be solved at the root label if we are not going to use further Router. If you are not feeling comfortable catching all kind of errors, I think this implementation is more considerate:. You mixed multiple concepts here from router-link s to programmatic navigation, to query params to a state store. That makes it a bit difficult to help you and tell you what the "correct" solution here is. Learn more. Asked 7 months ago. Active 7 days ago.
