  • Generate a postman JSON to be able to import and make calls to the Backend GraphQL API
  • It uses graphql-HTTP
  • It has a test with Jest or a Test Runner of choice

How to guarantee a better chance of being hired by front end?

  • Use Shadcn
  • Use vite with React Router latest version
  • Create a storybook of your UI components
  • Create a dash such as a real bank
