|
| 1 | +Welcome to your new TanStack app! |
| 2 | + |
| 3 | +# Getting Started |
| 4 | + |
| 5 | +To run this application: |
| 6 | + |
| 7 | +```bash |
| 8 | +pnpm install |
| 9 | +pnpm start |
| 10 | +``` |
| 11 | + |
| 12 | +# Building For Production |
| 13 | + |
| 14 | +To build this application for production: |
| 15 | + |
| 16 | +```bash |
| 17 | +pnpm build |
| 18 | +``` |
| 19 | + |
| 20 | +## Testing |
| 21 | + |
| 22 | +This project uses [Vitest](https://vitest.dev/) for testing. You can run the tests with: |
| 23 | + |
| 24 | +```bash |
| 25 | +pnpm test |
| 26 | +``` |
| 27 | + |
| 28 | +## Styling |
| 29 | + |
| 30 | +This project uses [Tailwind CSS](https://tailwindcss.com/) for styling. |
| 31 | + |
| 32 | +## Routing |
| 33 | + |
| 34 | +This project uses [TanStack Router](https://tanstack.com/router). The initial setup is a file based router. Which means that the routes are managed as files in `src/routes`. |
| 35 | + |
| 36 | +### Adding A Route |
| 37 | + |
| 38 | +To add a new route to your application just add another a new file in the `./src/routes` directory. |
| 39 | + |
| 40 | +TanStack will automatically generate the content of the route file for you. |
| 41 | + |
| 42 | +Now that you have two routes you can use a `Link` component to navigate between them. |
| 43 | + |
| 44 | +### Adding Links |
| 45 | + |
| 46 | +To use SPA (Single Page Application) navigation you will need to import the `Link` component from `@tanstack/react-router`. |
| 47 | + |
| 48 | +```tsx |
| 49 | +import { Link } from '@tanstack/react-router' |
| 50 | +``` |
| 51 | + |
| 52 | +Then anywhere in your JSX you can use it like so: |
| 53 | + |
| 54 | +```tsx |
| 55 | +<Link to="/about">About</Link> |
| 56 | +``` |
| 57 | + |
| 58 | +This will create a link that will navigate to the `/about` route. |
| 59 | + |
| 60 | +More information on the `Link` component can be found in the [Link documentation](https://tanstack.com/router/v1/docs/framework/react/api/router/linkComponent). |
| 61 | + |
| 62 | +### Using A Layout |
| 63 | + |
| 64 | +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 the routes. The route content will appear in the JSX where you use the `<Outlet />` component. |
| 65 | + |
| 66 | +Here is an example layout that includes a header: |
| 67 | + |
| 68 | +```tsx |
| 69 | +import { Outlet, createRootRoute } from '@tanstack/react-router' |
| 70 | +import { TanStackRouterDevtools } from '@tanstack/react-router-devtools' |
| 71 | + |
| 72 | +import { Link } from '@tanstack/react-router' |
| 73 | + |
| 74 | +export const Route = createRootRoute({ |
| 75 | + component: () => ( |
| 76 | + <> |
| 77 | + <header> |
| 78 | + <nav> |
| 79 | + <Link to="/">Home</Link> |
| 80 | + <Link to="/about">About</Link> |
| 81 | + </nav> |
| 82 | + </header> |
| 83 | + <Outlet /> |
| 84 | + <TanStackRouterDevtools /> |
| 85 | + </> |
| 86 | + ), |
| 87 | +}) |
| 88 | +``` |
| 89 | + |
| 90 | +The `<TanStackRouterDevtools />` component is not required so you can remove it if you don't want it in your layout. |
| 91 | + |
| 92 | +More information on layouts can be found in the [Layouts documentation](https://tanstack.com/router/latest/docs/framework/react/guide/routing-concepts#layouts). |
| 93 | + |
| 94 | +## Data Fetching |
| 95 | + |
| 96 | +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. |
| 97 | + |
| 98 | +For example: |
| 99 | + |
| 100 | +```tsx |
| 101 | +const peopleRoute = createRoute({ |
| 102 | + getParentRoute: () => rootRoute, |
| 103 | + path: '/people', |
| 104 | + loader: async () => { |
| 105 | + const response = await fetch('https://swapi.dev/api/people') |
| 106 | + return response.json() as Promise<{ |
| 107 | + results: { |
| 108 | + name: string |
| 109 | + }[] |
| 110 | + }> |
| 111 | + }, |
| 112 | + component: () => { |
| 113 | + const data = peopleRoute.useLoaderData() |
| 114 | + return ( |
| 115 | + <ul> |
| 116 | + {data.results.map((person) => ( |
| 117 | + <li key={person.name}>{person.name}</li> |
| 118 | + ))} |
| 119 | + </ul> |
| 120 | + ) |
| 121 | + }, |
| 122 | +}) |
| 123 | +``` |
| 124 | + |
| 125 | +Loaders simplify your data fetching logic dramatically. Check out more information in the [Loader documentation](https://tanstack.com/router/latest/docs/framework/react/guide/data-loading#loader-parameters). |
| 126 | + |
| 127 | +### React-Query |
| 128 | + |
| 129 | +React-Query is an excellent addition or alternative to route loading and integrating it into you application is a breeze. |
| 130 | + |
| 131 | +First add your dependencies: |
| 132 | + |
| 133 | +```bash |
| 134 | +pnpm add @tanstack/react-query @tanstack/react-query-devtools |
| 135 | +``` |
| 136 | + |
| 137 | +Next we'll need to create a query client and provider. We recommend putting those in `main.tsx`. |
| 138 | + |
| 139 | +```tsx |
| 140 | +import { QueryClient, QueryClientProvider } from '@tanstack/react-query' |
| 141 | + |
| 142 | +// ... |
| 143 | + |
| 144 | +const queryClient = new QueryClient() |
| 145 | + |
| 146 | +// ... |
| 147 | + |
| 148 | +if (!rootElement.innerHTML) { |
| 149 | + const root = ReactDOM.createRoot(rootElement) |
| 150 | + |
| 151 | + root.render( |
| 152 | + <QueryClientProvider client={queryClient}> |
| 153 | + <RouterProvider router={router} /> |
| 154 | + </QueryClientProvider>, |
| 155 | + ) |
| 156 | +} |
| 157 | +``` |
| 158 | + |
| 159 | +You can also add TanStack Query Devtools to the root route (optional). |
| 160 | + |
| 161 | +```tsx |
| 162 | +import { ReactQueryDevtools } from '@tanstack/react-query-devtools' |
| 163 | + |
| 164 | +const rootRoute = createRootRoute({ |
| 165 | + component: () => ( |
| 166 | + <> |
| 167 | + <Outlet /> |
| 168 | + <ReactQueryDevtools buttonPosition="top-right" /> |
| 169 | + <TanStackRouterDevtools /> |
| 170 | + </> |
| 171 | + ), |
| 172 | +}) |
| 173 | +``` |
| 174 | + |
| 175 | +Now you can use `useQuery` to fetch your data. |
| 176 | + |
| 177 | +```tsx |
| 178 | +import { useQuery } from '@tanstack/react-query' |
| 179 | + |
| 180 | +import './App.css' |
| 181 | + |
| 182 | +function App() { |
| 183 | + const { data } = useQuery({ |
| 184 | + queryKey: ['people'], |
| 185 | + queryFn: () => |
| 186 | + fetch('https://swapi.dev/api/people') |
| 187 | + .then((res) => res.json()) |
| 188 | + .then((data) => data.results as { name: string }[]), |
| 189 | + initialData: [], |
| 190 | + }) |
| 191 | + |
| 192 | + return ( |
| 193 | + <div> |
| 194 | + <ul> |
| 195 | + {data.map((person) => ( |
| 196 | + <li key={person.name}>{person.name}</li> |
| 197 | + ))} |
| 198 | + </ul> |
| 199 | + </div> |
| 200 | + ) |
| 201 | +} |
| 202 | + |
| 203 | +export default App |
| 204 | +``` |
| 205 | + |
| 206 | +You can find out everything you need to know on how to use React-Query in the [React-Query documentation](https://tanstack.com/query/latest/docs/framework/react/overview). |
| 207 | + |
| 208 | +## State Management |
| 209 | + |
| 210 | +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. |
| 211 | + |
| 212 | +First you need to add TanStack Store as a dependency: |
| 213 | + |
| 214 | +```bash |
| 215 | +pnpm add @tanstack/store |
| 216 | +``` |
| 217 | + |
| 218 | +Now let's create a simple counter in the `src/App.tsx` file as a demonstration. |
| 219 | + |
| 220 | +```tsx |
| 221 | +import { useStore } from '@tanstack/react-store' |
| 222 | +import { Store } from '@tanstack/store' |
| 223 | +import './App.css' |
| 224 | + |
| 225 | +const countStore = new Store(0) |
| 226 | + |
| 227 | +function App() { |
| 228 | + const count = useStore(countStore) |
| 229 | + return ( |
| 230 | + <div> |
| 231 | + <button onClick={() => countStore.setState((n) => n + 1)}> |
| 232 | + Increment - {count} |
| 233 | + </button> |
| 234 | + </div> |
| 235 | + ) |
| 236 | +} |
| 237 | + |
| 238 | +export default App |
| 239 | +``` |
| 240 | + |
| 241 | +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. |
| 242 | + |
| 243 | +Let's check this out by doubling the count using derived state. |
| 244 | + |
| 245 | +```tsx |
| 246 | +import { useStore } from '@tanstack/react-store' |
| 247 | +import { Store, Derived } from '@tanstack/store' |
| 248 | +import './App.css' |
| 249 | + |
| 250 | +const countStore = new Store(0) |
| 251 | + |
| 252 | +const doubledStore = new Derived({ |
| 253 | + fn: () => countStore.state * 2, |
| 254 | + deps: [countStore], |
| 255 | +}) |
| 256 | +doubledStore.mount() |
| 257 | + |
| 258 | +function App() { |
| 259 | + const count = useStore(countStore) |
| 260 | + const doubledCount = useStore(doubledStore) |
| 261 | + |
| 262 | + return ( |
| 263 | + <div> |
| 264 | + <button onClick={() => countStore.setState((n) => n + 1)}> |
| 265 | + Increment - {count} |
| 266 | + </button> |
| 267 | + <div>Doubled - {doubledCount}</div> |
| 268 | + </div> |
| 269 | + ) |
| 270 | +} |
| 271 | + |
| 272 | +export default App |
| 273 | +``` |
| 274 | + |
| 275 | +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. |
| 276 | + |
| 277 | +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. |
| 278 | + |
| 279 | +You can find out everything you need to know on how to use TanStack Store in the [TanStack Store documentation](https://tanstack.com/store/latest). |
