| 1 | +# Create Login Page |
| 2 | + |
| 3 | +Welcome to the tutorial! We will build a compact yet feature-rich login page component, teaching you how to quickly create a login page component. |
| 4 | + |
| 5 | +## Step 1: Create the Login Page Container |
| 6 | + |
| 7 | +```tsx |
| 8 | +import { FC, PropsWithChildren } from 'react'; |
| 9 | +import { Render, Provider, Container } from 'react-login-page'; |
| 10 | + |
| 11 | +const RenderLogin = () => { |
| 12 | + return ( |
| 13 | + <Render> |
| 14 | + <div className="login-page-example-wrapper"> </div> |
| 15 | + </Render> |
| 16 | + ); |
| 17 | +}; |
| 18 | + |
| 19 | +const LoginPage: FC<PropsWithChildren<React.HTMLAttributes<HTMLDivElement>>> = ({ |
| 20 | + children, |
| 21 | + className, |
| 22 | + ...divProps |
| 23 | +}) => { |
| 24 | + return ( |
| 25 | + <Provider> |
| 26 | + <Container {...divProps} className={`login-page-example ${className || ''}`}> |
| 27 | + <RenderLogin /> |
| 28 | + {children} |
| 29 | + </Container> |
| 30 | + </Provider> |
| 31 | + ); |
| 32 | +}; |
| 33 | + |
| 34 | +type LoginComponent = FC<PropsWithChildren<React.HTMLAttributes<HTMLDivElement>>> & {}; |
| 35 | +const Login = LoginPage as LoginComponent; |
| 36 | +Login.displayName = 'LoginExamplePage'; |
| 37 | + |
| 38 | +export default Login; |
| 39 | +``` |
| 40 | + |
| 41 | +In the example above, we defined an empty `Login` component. The `<Provider>` component is used for data collection, and the layout is placed inside the `<Container>` component, which wraps a `div` around the content to be rendered. The `<Render>` component provides a flexible API to help render the component layout. |
| 42 | + |
| 43 | +## Step 2: Define a `Title` Component |
| 44 | + |
| 45 | +```tsx |
| 46 | +import { PropsWithChildren } from 'react'; |
| 47 | +import { Block, BlockProps, BlockTagType } from 'react-login-page'; |
| 48 | + |
| 49 | +export const Title = <T extends BlockTagType>(props: PropsWithChildren<Partial<BlockProps<T>>>) => { |
| 50 | + const { keyname = 'title', ...elmProps } = props; |
| 51 | + if (!elmProps.children) { |
| 52 | + elmProps.children = 'Login'; |
| 53 | + } |
| 54 | + return <Block {...elmProps} keyname={keyname} />; |
| 55 | +}; |
| 56 | + |
| 57 | +Title.displayName = 'ExampleLogin.Title'; |
| 58 | +``` |
| 59 | + |
| 60 | +When using the `<Title>` component, we need to write the display logic. The `keyname` defined in the `<Title>` component is very important, as we need it when displaying the component. Its purpose is to give your component a name, and determine its position based on the name when displaying it. |
| 61 | + |
| 62 | +```tsx |
| 63 | +import { Render, useStore } from 'react-login-page'; |
| 64 | + |
| 65 | +const RenderLogin = () => { |
| 66 | + const { blocks = {} } = useStore(); |
| 67 | + return ( |
| 68 | + <Render> |
| 69 | + <div className="login-page-example-wrapper"> |
| 70 | + <h2>{blocks.title}</h2> |
| 71 | + </div> |
| 72 | + </Render> |
| 73 | + ); |
| 74 | +}; |
| 75 | +``` |
| 76 | + |
| 77 | +If you need to display the `<Title>` component by default, you should add it to the `<Provider>` component by default. |
| 78 | + |
| 79 | +```tsx |
| 80 | +<Provider> |
| 81 | + <Title>Example Title</Title> |
| 82 | +</Provider> |
| 83 | +``` |
| 84 | + |
| 85 | +## Step 3: Define an `Input Box` Component |
| 86 | + |
| 87 | +```tsx |
| 88 | +import { FC } from 'react'; |
| 89 | +import { Input, InputProps } from 'react-login-page'; |
| 90 | + |
| 91 | +export const Username: FC<InputProps> = (props) => { |
| 92 | + const { keyname = 'username', name, ...elmProps } = props; |
| 93 | + return ( |
| 94 | + <Input placeholder="Username" spellCheck={false} {...elmProps} name={name || keyname} keyname={keyname || name} /> |
| 95 | + ); |
| 96 | +}; |
| 97 | + |
| 98 | +Username.displayName = 'LoginExamplePage.Username'; |
| 99 | +``` |
| 100 | + |
| 101 | +By default, you need to display the `<Username />` component, so add it to the `<Provider>` component. |
| 102 | + |
| 103 | +```tsx |
| 104 | +<Provider> |
| 105 | + <Username /> |
| 106 | +</Provider> |
| 107 | +``` |
| 108 | + |
| 109 | +## Step 4: Define a `Submit Button` Component |
| 110 | + |
| 111 | +```tsx |
| 112 | +import { FC } from 'react'; |
| 113 | +import { Button, ButtonProps } from 'react-login-page'; |
| 114 | + |
| 115 | +export const Submit: FC<ButtonProps> = (props) => { |
| 116 | + const { keyname = 'submit', ...elmProps } = props; |
| 117 | + if (!elmProps.children) { |
| 118 | + elmProps.children = 'Submit'; |
| 119 | + } |
| 120 | + return <Button type="submit" keyname={keyname} {...elmProps} />; |
| 121 | +}; |
| 122 | + |
| 123 | +Submit.displayName = 'LoginExamplePage.Submit'; |
| 124 | +``` |
| 125 | + |
| 126 | +By default, you need to display the `<Submit />` component, so add it to the `<Provider>` component. |
| 127 | + |
| 128 | +```tsx |
| 129 | +<Provider> |
| 130 | + <Submit /> |
| 131 | +</Provider> |
| 132 | +``` |
| 133 | + |
| 134 | +If you also need to display a `Reset Button` by default, you can add another one based on `<Submit />` in the `<Provider>` component: |
| 135 | + |
| 136 | +```tsx |
| 137 | +<Provider> |
| 138 | + <Submit /> |
| 139 | + <Submit keyname="resetBtn" type="reset"> |
| 140 | + Reset |
| 141 | + </Submit> |
| 142 | +</Provider> |
| 143 | +``` |
| 144 | + |
| 145 | +## Step 5: Provide a Point Component |
| 146 | + |
| 147 | +Defines [dot notation](https://legacy.reactjs.org/docs/jsx-in-depth.html#using-dot-notation-for-jsx-type) components. |
| 148 | + |
| 149 | +```tsx |
| 150 | +type LoginComponent = FC<PropsWithChildren<React.HTMLAttributes<HTMLDivElement>>> & { |
| 151 | + Title: typeof Title; |
| 152 | + Username: typeof Username; |
| 153 | + Submit: typeof Submit; |
| 154 | +}; |
| 155 | +const Login = LoginPage as LoginComponent; |
| 156 | + |
| 157 | +Login.displayName = 'LoginExamplePage'; |
| 158 | +Login.Title = Title; |
| 159 | +Login.Username = Username; |
| 160 | +Login.Submit = Submit; |
| 161 | + |
| 162 | +export default Login; |
| 163 | +``` |
| 164 | + |
| 165 | +## Using the Defined Component |
| 166 | + |
| 167 | +```tsx |
| 168 | +import LoginExample from '../login'; |
| 169 | + |
| 170 | +function Demo() { |
| 171 | + return <LoginExample />; |
| 172 | +} |
| 173 | +``` |
| 174 | + |
| 175 | +## Complete Example |
| 176 | + |
| 177 | +```tsx mdx:preview |

| 187 | + if (!elmProps.children) { |
| 188 | + elmProps.children = 'Login'; |

| 234 | + }); |
| 235 | + })} |
| 236 | + </section> |
