Well be building a simple joke listing app with Gin. We're a place where coders share, stay up-to-date and grow their careers. Made with love and Ruby on Rails. The parseHash method initializes the auth0 webAuth client and parses the hash to a more readable format, saving them to localSt. It delivers a very minimalistic framework that carries with it only the most essential features, libraries, and functionalities needed to build web applications and microservices. Gin is a high-performance micro-framework. Well also add a like method, which will increment the likes of a Joke. It decides which component to show based on whether a user is authenticated or not. Switch on the "Enable RBAC" and "Add Permissions in the Access Token" options. In the settings, let's set the callback to http://localhost:3000: With the credentials in place, lets update our React components. This component is displayed when a user is authenticated. You can check their home page to find out more.
This component bootstraps our entire React app. http://localhost:3000/api/jokes will return a 200 OK header response, with the message jokes handler not implemented yet.
Navigate to the Clients section in your dashboard. You can say Hi to me on Twitter @codehakase, Learn to code for free. Check out some of the features below that make it a worthy framework to consider for your next Golang project.
You should see the Home component with a signin button. To show the lock screen, capture and store the user token and add the correct authorization header to any requests to our API. and your own database of users, with just a few lines of code. Our middleware checks and receives a token from a request and calls the jwtMiddleWare.CheckJWT method to validate the token sent. Additional information can be found here. Visit the "Add Permissions to Roles" document for more details. You can customize the Auth0 login page with your branding and enable different authentication methods, such as logging in with a username/password combination or a social provider like Facebook or Google. You have learned how to build an application and an API with Go and the Gin framework. Well start off with just its base, and later update it with more functionality.

Clicking on the signin button will redirect to a hosted Lock page (create an account or login) to continue using the application. We are going to add authentication to it, so that all logged-in users will have the privilege to like and view jokes. You can use the Auth0 Dashboard to enable Role-Based Access Control (RBAC) and then implement it by creating API permissions, assigning those permissions to a role, and assigning that role to a user. Visit the "Register Applications" document for more details. The access token present in the authorization header of a request must include a permissions claim that contains the read:admin-messages permission to access the GET /api/messages/admin endpoint. This guide will show you how to build full stack Web App from scratch using Go programming language, Gin and React frameworks. DEV Community 2016 - 2022. https://github.com/ynwd/monorepo/tree/typescript, https://github.com/ynwd/monorepo/tree/fastrex, Measuring mutex, channel and waitGroup performance. We have our API in place, so lets build a frontend to present the data from our API. and only accessible to ynwd. We can test with cURL or postman , and then send a GET request to http://localhost:3000/jokes to get the full list of jokes, and a POST request to http://localhost:3000/jokes/like/{jokeid} to increment the likes of a joke. Lets restart our Go server go run main.go, and head over to our app's URL http://localhost:3000/.
We have to add the credentials needed for our API to an environment variable. Since its a small application, its going to be easy to build the application with just go run from the terminal. Open the Users section from the Auth0 Dashboard.

clone repo: https://github.com/ynwd/monorepo/tree/typescript, You can see the final source code here: https://github.com/ynwd/monorepo/tree/fastrex. Lets install the jwtmiddleware libraries: Lets source our environment file, and restart our app server: Now if we try accessing any of the endpoints, well be faced with a 401 Unauthorized error.
