html 助手

¥html Helper

html Helper 允许你使用名为 html 的标记在 JavaScript 模板字面量中编写 HTML。使用 raw()，内容将按原样渲染。你必须自己转义这些字符串。

¥The html Helper lets you write HTML in JavaScript template literal with a tag named html. Using raw(), the content will be rendered as is. You have to escape these strings by yourself.

导入

¥Import

import { Hono } from 'hono'
import { html, raw } from 'hono/html'

`html`

const app = new Hono()

app.get('/:username', (c) => {
  const { username } = c.req.param()
  return c.html(
    html`<!doctype html>
      <h1>Hello! ${username}!</h1>`
  )
})

将代码片段插入 JSX

¥Insert snippets into JSX

将内联脚本插入 JSX：

¥Insert the inline script into JSX:

tsx

app.get('/', (c) => {
  return c.html(
    <html>
      <head>
        <title>Test Site</title>
        {html`
          <script>
            // No need to use dangerouslySetInnerHTML.
            // If you write it here, it will not be escaped.
          </script>
        `}
      </head>
      <body>Hello!</body>
    </html>
  )
})

充当功能组件

¥Act as functional component

由于 html 返回 HtmlEscapedString，因此它可以充当功能齐全的组件而无需使用 JSX。

¥Since html returns an HtmlEscapedString, it can act as a fully functional component without using JSX.

使用 `html` 代替 `memo` 来加速进程

¥Use html to speed up the process instead of memo

typescript

const Footer = () => html`
  <footer>
    <address>My Address...</address>
  </footer>
`

接收 props 并嵌入值

¥Receives props and embeds values

typescript

interface SiteData {
  title: string
  description: string
  image: string
  children?: any
}
const Layout = (props: SiteData) => html`
<html>
<head>
  <meta charset="UTF-8">
  <title>${props.title}</title>
  <meta name="description" content="${props.description}">
  <head prefix="og: http://ogp.me/ns#">
  <meta property="og:type" content="article">
  <!-- More elements slow down JSX, but not template literals. -->
  <meta property="og:title" content="${props.title}">
  <meta property="og:image" content="${props.image}">
</head>
<body>
  ${props.children}
</body>
</html>
`

const Content = (props: { siteData: SiteData; name: string }) => (
  <Layout {...props.siteData}>
    <h1>Hello {props.name}</h1>
  </Layout>
)

app.get('/', (c) => {
  const props = {
    name: 'World',
    siteData: {
      title: 'Hello <> World',
      description: 'This is a description',
      image: 'https://example.com/image.png',
    },
  }
  return c.html(<Content {...props} />)
})

`raw()`

app.get('/', (c) => {
  const name = 'John &quot;Johnny&quot; Smith'
  return c.html(html`<p>I'm ${raw(name)}.</p>`)
})

提示

¥Tips

得益于这些库，Visual Studio Code 和 vim 还将模板字面量解释为 HTML，从而允许应用语法高亮和格式化。

¥Thanks to these libraries, Visual Studio Code and vim also interprets template literals as HTML, allowing syntax highlighting and formatting to be applied.
