Part-2 Ionic&Vue JWT(JSON Web Token) Authentication(Refresh Token Implementation)

In  Part-1  we have learned about user authentication using the jwt access token in the Ionic&Vue application. This is the continuation article here our main goal to use refresh token on the expiration of the access token. NestJS(Nodejs) Todos API: In  Part-1  we discussed steps to set up the Nestjs API. In that API we have a secured endpoint called 'Todos'. In the next step, we are going to consume this 'Todo' API from our angular application. http://localhost:3000/todos Use Access Token As Authorization Header To Secured Endpoint: Now we will consume the secured endpoint(in our sample 'Todos' endpoint) by sending the access token value as the authorization header. So to work with the todos endpoint let's create a separate store module as below. src/store/modules/todo.js: import axios from "axios"; const store = () => ({ todos: [], }); const getters = { getAllTodos(state) { return state.todos; }, }; const actions = {

Part-1 Ionic&Vue JWT(JSON Web Token) Authentication(Access Token Implementation)

In this article, we are going to understand the implementation steps on jwt authentication in the Ionic5 Vue application. Here our main concentration is on the jwt access token to make the user authentication. What Is JSON Web Token?: JSON Web Token is a digitally signed and secured token for user validation. The jwt is constructed with 3 informative parts: Header Payload Signature Create A Sample App Of Ionic5 Using Vue : To begin to create an Ionic application, we should have the Ionic CLI installed in our system environment. Command to install latest Ionic CLI: npm install -g @ionic/cli@latest Now run the following command to create Ionic5 using the Vue application. Command to create Ionic Vue application ionic start your_app_name blank --type vue Now run the following command to install Vuex into our Ionic&Vue app. Vuex Command npm install vuex@next --save TypeScript Or Javascript: By default Ionic sample created with the support of TypeScript in any library like angula

Ionic & Vue Sample Application Using Vuex State Management

In this article, we are going to create a sample application of Ionic & Vue our main target is to implement Vuex State Management. Create A Sample App Of Ionic5 Using Vue : To begin to create an Ionic application, we should have the Ionic CLI installed in our system environment. Command to install latest Ionic CLI: npm install -g @ionic/cli@latest Now run the following command to create Ionic5 using the Vue application. Command to create Ionic Vue application ionic start your_app_name blank --type vue Now run the following command to install Vuex into our Ionic&Vue app. Vuex Command npm install vuex@next --save TypeScript Or Javascript: By default Ionic sample created with the support of TypeScript in any library like angular, react, and vue. Typescript can be chosen to develop our application. But in the case of Vue most of the developers or preferred to choose javascript syntax instead of Typescript for application development. So to make our Ionic Vue application use j

Implementing DataLoader For Query Execution Using Hot Chocolate GraphQL In .Net

In this article, we are going to understand and implement the DataLoader concept in Hot Chocolate GraphQL. Here we will use an existing Hot Chocolate sample application that was created in the introduction articles on Hot chocolate GraphQL. I recommend reading those articles: Part-1 Introduction On Hot Chocolate GraphQL Part-2 Introduction On Hot Chocolate GraphQL Issues Need To Fix: Before implementing the DataLoader into our sample we must aware of the issues we are facing. In GrphQL we have an option like Fragments Query. Fragments query is used to display the comparison results very effective way. Fragments Query: query{ Gadget1:GetByBrand(brand:"samsung"){ Id ProductName Brand } Gadget2:GetByBrand(brand:"red mi"){ Id ProductName Brand } } Here we request a GraphQL endpoint to serve the different gadgets for comparison this type of query called Fragments Query. Now this kind of Fragments Query produces issues like: We will face
