Starsky ClientApp

List of Starsky Projects

starsky/starsky/clientapp docs

On top of the Starsky API there is React front-end. This is required to run the web application

Available Scripts

In the project directory, you can run:

npm start

Runs the app in the development mode. Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits. You will also see any lint errors in the console.

Make sure you run the Starsky API on http://localhost:4000 or us a local tunnel proxy (which you can find in ./starsky-tools/localtunnel)

npm test

Launches the test runner in the interactive watch mode. See the section about running tests for more information. Although we don't use Create React App, we do use the same test runner. See and for more information.

npm test:ci

Run all unit tests and check if there are any errors

npm run build

Builds the app for production to the build folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.
Your app is ready to be deployed!

In this application we use the or build.ps1 to combine the frontend application with the .NET Core backend.

npm run storybook

Storybook is an open source tool for developing UI components in isolation for React and other platfoms. It makes building stunning UIs organized and efficient.

A Storybook is a collection of stories. Each story represents a single visual state of a component. Technically, a story is a function that returns something that can be rendered to screen.

Upgrade Vite to a newer version

Auto upgrade

In this project there is a script that auto upgrades the Vite to the latest version

npm run update:install

Run the tests afterwards to check if everything is working

npm ci && npm test:ci

Manual Upgrade

The default Vite / Typescript package is used to keep future upgrades less painfull. In the repository of Vite releases you can find if we are using the latest version.

To keep all Vite dependencies in place

npm create -y vite@latest clientapp -- --template react-ts

cd clientapp
npm install

Normal dependencies, that are included react, react-dom

Dev dependencies, that are included @types/react, @types/react-dom, @typescript-eslint/eslint-plugin, @typescript-eslint/parser, @vitejs/plugin-react, eslint, eslint-plugin-react-hooks, eslint-plugin-react-refresh, typescript, vite

Proxy tag for backend services & homepage

Used when running npm start

"proxy": "http://localhost:4000",
"homepage": "/starsky/",

npm run test:ci is used by the build-script to run all tests and ESlint

This is added to the package.json

collectCoverageFrom and coverageReporters

With jest collectCoverageFrom and coverageReporters are used to get the right output

Known issues

I keep getting this errors:

React + TypeScript + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

Expanding the ESLint configuration

If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:

  • Configure the top-level parserOptions property like this:
   parserOptions: {
ecmaVersion: 'latest',
sourceType: 'module',
project: ['./tsconfig.json', './tsconfig.node.json'],
tsconfigRootDir: __dirname,
  • Replace plugin:@typescript-eslint/recommended to plugin:@typescript-eslint/recommended-type-checked or plugin:@typescript-eslint/strict-type-checked
  • Optionally add plugin:@typescript-eslint/stylistic-type-checked
  • Install eslint-plugin-react and add plugin:react/recommended & plugin:react/jsx-runtime to the extends list
