Question

使用以下代码：

<svelte:head>
    <script type='application/ld+json'>
    {
    "@context": "https://schema.org",
    "@type": "Organization",
    "url": "https://filestar.com",
    "logo": "https://filestar.com/logo-512.png"
    }
    </script>
</svelte:head>

获得：

[svelte-preprocess] Error transforming 'ld+json'.

Message:
Cannot find module './transformers/ld+json'

Stack:

    at Promise.resolve.then (C:\Repos\Filestar-Website\web-vnext\node_modules\svelte-preprocess\dist\utils.js:112:61)

我尝试了这个github线程中的建议，结果相同：https://github.com/sveltejs/svelte/issues/2438

对于在此着陆的任何人，Rich's answer会为您指出正确的资源。

使用Sapper对我有用的是

// rollup.config.js
// ...
import sveltePreprocess from 'svelte-preprocess';

const preprocess = sveltePreprocess({
  preserve: ['ld+json'],
  // ...
});

export default {
  client: {
    plugins: [
      svelte({
        preprocess,
        // ...
      }),
  },
  server: {
    plugins: [
      svelte({
        preprocess,
        // ...
      }),
    ],
  },
};

<!-- index.svelte -->
<script>
  let jsonld = {
    "@context": "http://schema.org",
    "@type": "...",
    "...": "..."
  };
  jsonld = JSON.stringify(jsonld);
</script>

<svelte:head>
  {@html `<script type="application/ld+json">${jsonld}</script>`}
</svelte:head>

附加说明：使用prettier和prettier-plugin-svelte，svelte组件会得到不需要的更改。执行以下操作可以解决我的问题。

<!-- index.svelte -->
<script>
  let jsonld = {
    "@context": "http://schema.org",
    "@type": "...",
    "...": "..."
  };
  jsonld = JSON.stringify(jsonld);
  let jsonldScript = `<script type="application/ld+json">${jsonld +
    "<"}/script>`;
</script>

<svelte:head>
  {@html jsonldScript}
</svelte:head>

Answer 2

看起来与svelte-preprocess有关。尝试添加preserve: ['ld+json'] option。

Answer 3

根据this comment，这是另一种方法。

<script>
  const schema = {
    "@context": "https://schema.org",
    "@type": "Organization",
    "url": "https://filestar.com",
    "logo": "https://filestar.com/logo-512.png"
  }
</script>

<svelte:head>
  {@html 
    `
    <script type="application/ld+json">
      ${JSON.stringify(schema)}
    </script>
    `
  }
</svelte:head>

苗条：application / ld + json
