I'm 99% sure that you've already used an OAuth based API. > 👉 If you signed up with your GitHub account on Hackernoon, you've used the GitHub API using their implementation of OAuth2. Every time you sign-in with Google (or Facebook) on a website, you are using OAuth2 as well. OAuth (especially OAuth2) is now everywhere, probably because it's the best authentication framework in terms of user experience (UX). The user clicks on a button, grants permission, and . voilà But in terms of developer experience (DX), OAuth is... tricky. Especially for beginners. Why? Probably because it introduces a lot of new concepts at once (see comments below). Today, I'll showcase something that we're proud of at Bearer.sh, , which helps with OAuth by focusing exclusively on the DX. I'm not saying that it makes OAuth great again for developers, but you get the idea. Pizzly Let's see how it looks like 👉 Curious about how you can do it on your application? Here's a full guide. The Vue.js skeleton To learn how to use an OAuth based API, we need a Vue.js skeleton. And the least that we need is an app that consumes an API endpoint using OAuth2. As you probably have a GitHub account, we will use that API, but you can easily switch to any other API that uses OAuth2 (Slack, Salesforce, ...) or OAuth1 (Twitter, Trello, ...). The GitHub API provides a handy endpoint ( ) to list all the repositories that a user has starred. This endpoint accepts authentication, so it looks like a good use case. /user/starred Here's how the application will look like: Latest repositories starred {{repository.name}} Whoa, such empty! Connect to GitHub <!DOCTYPE html> < > html < > body < = > div id "app" < = > main v-if "user" < > h1 </ > h1 < > ul < = > li v-for "repository in repositories" < = = > a :href "repository.html_url" target "_blank" </ > a </ > li </ > ul < = > p v-if "repositories.length === 0" </ > p </ > main < > div v-else < @ = > button click.prevent "connect" </ > button </ > div </ > div  < = > script src "https://cdn.jsdelivr.net/npm/pizzly-js@v0.2.7/dist/index.umd.min.js" </ > script  < = > script src "https://cdn.jsdelivr.net/npm/vue/dist/vue.js" </ > script < > script app = Vue({
        el: ,
        data: {
          user: ,
          repositories: []
        }
      }) var new '#app' null </ > script </ > body </ > html It's a very basic Vue.js application that displays the content of repositories[] when the user variable is set. Otherwise, it asks the user to connect to GitHub. The authentication part As said, we gonna use , an open-source project that handles OAuth dances, without headaches. It provides a method that triggers an authentication flow from your frontend. No need to deal with a backend, it's fully handled from the front. Pizzly .connect() Let's see how to update the skeleton above to use with Pizzly: app = Vue({ : , : { : , : []
  }, : { .$pizzly = Pizzly({ : , : }); }, : { : { .$pizzly
        .integration( )
        .connect()
        .then( .connectSuccess)
        .catch( .connectError);
    }, : { .user = data.authId; .log( )
    }, : { .error(err)
      alert( )
    }
  }
}); var new el "#app" data user null repositories mounted ( ) function // Here we initialize Pizzly. this new host "pushtogsheet.herokuapp.com" publishableKey "pope8Qy8qfYyppnHRMgLMpQ8MuEUKDGeyhfGCj" // I'm using my own instance of Pizzly which is hosted on Heroku. // Create yours for free and in a few clicks by following // https://github.com/Bearer/Pizzly#getting-started methods connect ( ) function // Here, we create a new method // that "connect" a user to GitHub this 'github' this this connectSuccess ( ) function data // On success, we update the user object this console 'Successfully logged in!' connectError ( ) function err console "Something went wrong. Look at the logs." That's it. A few lines of code in your application and you are ready to handle any OAuth based API 💪. The configuration part Pizzly is a self-hosted OAuth manager. This means that you need to host it somewhere, for example on Heroku (it takes 30 seconds). Once hosted somewhere, you can access Pizzly's dashboard, which is where you configure your GitHub integration. And ! voilà What's next? You now know how to authenticate a user towards any OAuth based API using a Vue.js application. It's easily adaptable to . No need to create backend routes or understand every single concepts of OAuth. Pizzly takes care of that for you (and for the experts, Pizzly automatically refreshes the ). all the most famous APIs access_token Again, to have a full understanding of the code and share your thoughts/questions in the comments below 👇 have a look at the CodePen Previously published at https://dev.to/bearer/how-to-use-an-oauth-based-api-in-vue-js-1elo
