tip: this frontend is designed to work with Flask-based Backend. It is recommended you stand up the backend first, test using Postman, and then the frontend should integrate smoothly.
This project depends on Nodejs and Node Package Manager (NPM). Before continuing, you must download and install Node (the download includes NPM) from https://nodejs.com/en/download.
The Ionic Command Line Interface is required to serve and build the frontend. Instructions for installing the CLI is in the Ionic Framework Docs.
This project uses NPM to manage software dependencies. NPM Relies on the package.json file located in the frontend directory of this repository. After cloning, open your terminal and run:
npm installtip: npm i is shorthand for npm install
Ionic ships with a useful development server which detects changes and transpiles as you work. The application is then accessible through the browser on a localhost port. To run the development server, cd into the frontend directory and run:
ionic servetip: Do not use ionic serve in production. Instead, build Ionic into a build artifact for your desired platforms. Checkout the Ionic docs to learn more
The authentication system used for this project is Auth0. ./src/services/auth.service.ts contains the logic to direct a user to the Auth0 login page, managing the JWT token upon successful callback, and handle setting and retrieving the token from the local store. This token is then consumed by our DrinkService (./src/services/auth.service.ts) and passed as an Authorization header when making requests to our backend.
The Auth0 JWT includes claims for permissions based on the user's role within the Auth0 system. This project makes use of these claims using the auth.can(permission) method which checks if particular permissions exist within the JWT permissions claim of the currently logged in user. This method is defined in ./src/services/auth.service.ts and is then used to enable and disable buttons in ./src/pages/drink-menu/drink-form/drink-form.html.
