🪝 Git Hooks

This project uses Husky and lint-staged for automatic code quality checks.

Pre-commit

Automatically runs lint and format checks on staged files:

• *.ts, *.tsx, *.js, *.jsx → Biome lint + format check with auto-fix
• *.json, *.css, *.md → Biome format check with auto-fix

Pre-push

Runs full project validation before push:

1. TypeScript type check
2. Lint check
3. Test execution

Push is blocked if any check fails.

🔄 CI/CD

GitHub Actions automatically runs CI pipeline on push or PR to main, dev, epic/** branches.

🎨 Styling

This project uses Tailwind CSS for styling.

🛣️ Routing

This project uses TanStack Router. The initial setup is a file based router, which means routes are managed as files in src/routes.

Adding A Route

To add a new route to your application, just add a new file in the ./src/routes directory.

TanStack will automatically generate the content of the route file for you.

Now that you have two routes you can use a Link component to navigate between them.

Adding Links

To use SPA (Single Page Application) navigation, import the Link component from @tanstack/react-router.

import{Link}from"@tanstack/react-router";

Then anywhere in your JSX you can use it like so:

<Linkto="/about">About</Link>

This will create a link that will navigate to the /about route.

More information on the Link component can be found in the Link documentation.

Using A Layout

In the File Based Routing setup, the layout is located in src/routes/__root.tsx. Anything you add to the root route will appear in all routes. The route content will appear in the JSX where you use the <Outlet /> component.

Here is an example layout that includes a header:

import{Outlet,createRootRoute}from"@tanstack/react-router";import{TanStackRouterDevtools}from"@tanstack/react-router-devtools";import{Link}from"@tanstack/react-router";exportconstRoute=createRootRoute({component: ()=>(<><header><nav><Linkto="/">Home</Link><Linkto="/about">About</Link></nav></header><Outlet/><TanStackRouterDevtools/></>),});

The <TanStackRouterDevtools /> component is not required, so you can remove it if you don't want it in your layout.

More information on layouts can be found in the Layouts documentation.

📡 Data Fetching

There are multiple ways to fetch data in your application. You can use TanStack Query to fetch data from a server. But you can also use the loader functionality built into TanStack Router to load the data for a route before it's rendered.

For example:

constpeopleRoute=createRoute({getParentRoute: ()=>rootRoute,path: "/people",loader: async()=>{constresponse=awaitfetch("https://swapi.dev/api/people");returnresponse.json()asPromise<{results: {name: string;}[];}>;},component: ()=>{constdata=peopleRoute.useLoaderData();return(<ul>{data.results.map((person)=>(<likey={person.name}>{person.name}</li>))}</ul>);},});

Loaders simplify your data fetching logic dramatically. Check out more information in the Loader documentation.

React-Query

React-Query is an excellent addition or alternative to route loading and integrating it into your application is a breeze.

First add your dependencies:

bun install @tanstack/react-query @tanstack/react-query-devtools

Next, create a query client and provider. We recommend putting those in main.tsx.

import{QueryClient,QueryClientProvider}from"@tanstack/react-query";// ...constqueryClient=newQueryClient();// ...if(!rootElement.innerHTML){constroot=ReactDOM.createRoot(rootElement);root.render(<QueryClientProviderclient={queryClient}><RouterProviderrouter={router}/></QueryClientProvider>);}

You can also add TanStack Query Devtools to the root route (optional).

import{ReactQueryDevtools}from"@tanstack/react-query-devtools";constrootRoute=createRootRoute({component: ()=>(<><Outlet/><ReactQueryDevtoolsbuttonPosition="top-right"/><TanStackRouterDevtools/></>),});

Now you can use useQuery to fetch your data.

import{useQuery}from"@tanstack/react-query";import"./App.css";functionApp(){const{ data }=useQuery({queryKey: ["people"],queryFn: ()=>fetch("https://swapi.dev/api/people").then((res)=>res.json()).then((data)=>data.resultsas{name: string}[]),initialData: [],});return(<div><ul>{data.map((person)=>(<likey={person.name}>{person.name}</li>))}</ul></div>);}exportdefaultApp;

You can find out everything you need to know on how to use React-Query in the React-Query documentation.

🗃️ State Management

Another common requirement for React applications is state management. There are many options for state management in React. TanStack Store provides a great starting point for your project.

First you need to add TanStack Store as a dependency:

bun install @tanstack/store

Now let's create a simple counter in the src/App.tsx file as a demonstration.

import{useStore}from"@tanstack/react-store";import{Store}from"@tanstack/store";import"./App.css";constcountStore=newStore(0);functionApp(){constcount=useStore(countStore);return(<div><buttononClick={()=>countStore.setState((n)=>n+1)}>
Increment - {count}</button></div>);}exportdefaultApp;

One of the many nice features of TanStack Store is the ability to derive state from other state. That derived state will update when the base state updates.

Let's check this out by doubling the count using derived state.

import{useStore}from"@tanstack/react-store";import{Store,Derived}from"@tanstack/store";import"./App.css";constcountStore=newStore(0);constdoubledStore=newDerived({fn: ()=>countStore.state*2,deps: [countStore],});doubledStore.mount();functionApp(){constcount=useStore(countStore);constdoubledCount=useStore(doubledStore);return(<div><buttononClick={()=>countStore.setState((n)=>n+1)}>
Increment - {count}</button><div>Doubled - {doubledCount}</div></div>);}exportdefaultApp;

We use the Derived class to create a new store that is derived from another store. The Derived class has a mount method that will start the derived store updating.

Once we've created the derived store we can use it in the App component just like we would any other store using the useStore hook.

You can find out everything you need to know on how to use TanStack Store in the TanStack Store documentation.

📁 Demo Files

Files prefixed with demo can be safely deleted. They are there to provide a starting point for you to play around with the features you've installed.
