html from api

Hello, I need to load an HTML from the API and display it directly. I now have a kind of solution, but it does not work properly because this API does not require authentication. What is the best way to do this?

'/my/ticket/**': {
      appMiddleware: 'auth',
      proxy: {
        to: process.env.API_URL + '/api/tickets/**',
        headers: {
          'Authorization': 'Bearer X'
        }
      }
    },

'/my/ticket/**': {
      appMiddleware: 'auth',
      proxy: {
        to: process.env.API_URL + '/api/tickets/**',
        headers: {
          'Authorization': 'Bearer X'
        }
      }
    },

Hi @Moritz Walter. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To load HTML from an API and display it directly in Nuxt, while handling authentication, there are a few approaches you can consider. Based on the information provided in the knowledge sources, here's a recommended solution: 1. Create a custom API endpoint in your Nuxt server to proxy the request to the external API. This allows you to handle authentication and avoid CORS issues. 2. Use useFetch or $fetch in your component to fetch the HTML from your custom endpoint. Here's how you can implement this: 1. Create a server route to proxy the API request:

// server/api/ticket/[id].ts
export default defineEventHandler(async (event) => {
  const config = useRuntimeConfig()
  const id = event.context.params.id

  // You can handle authentication here if needed
  const token = 'Your_Auth_Token'

  const response = await $fetch(`${config.apiUrl}/api/tickets/${id}`, {
    headers: {
      'Authorization': `Bearer ${token}`
    }
  })

  return response
})

// server/api/ticket/[id].ts
export default defineEventHandler(async (event) => {
  const config = useRuntimeConfig()
  const id = event.context.params.id

  // You can handle authentication here if needed
  const token = 'Your_Auth_Token'

  const response = await $fetch(`${config.apiUrl}/api/tickets/${id}`, {
    headers: {
      'Authorization': `Bearer ${token}`
    }
  })

  return response
})

2. In your component, use useFetch to get the HTML:

<template>
  <div v-if="pending">Loading...</div>
  <div v-else-if="error">Error: {{ error }}</div>
  <div v-else v-html="data"></div>
</template>

<script setup>
const route = useRoute()
const { data, pending, error } = await useFetch(`/api/ticket/${route.params.id}`)
</script>

<template>
  <div v-if="pending">Loading...</div>
  <div v-else-if="error">Error: {{ error }}</div>
  <div v-else v-html="data"></div>
</template>

<script setup>
const route = useRoute()
const { data, pending, error } = await useFetch(`/api/ticket/${route.params.id}`)
</script>

This approach has several advantages: 1. It keeps your API credentials secure on the server-side. 2. It avoids CORS issues since the request to the external API is made from your server. 3. It uses Nuxt's built-in useFetch composable, which handles SSR correctly Docs > Getting-started > Data fetching (https://nuxt.com/docs/getting-started/data-fetching#the-need-for-usefetch-and-useasyncdata). Remember to sanitize the HTML content if it's from an untrusted source to prevent XSS attacks. For authentication, you can use a more robust solution like the auth middleware you mentioned. You can create a plugin to handle authentication and add the token to all requests:

// plugins/api.ts
export default defineNuxtPlugin((nuxtApp) => {
  const { session } = useUserSession()

  const api = $fetch.create({
    baseURL: '<https://api.nuxt.com',>
    onRequest({ options }) {
      if (session.value?.token) {
        options.headers.set('Authorization', `Bearer ${session.value?.token}`)
      }
    }
  })

  return {
    provide: {
      api
    }
  }
})

// plugins/api.ts
export default defineNuxtPlugin((nuxtApp) => {
  const { session } = useUserSession()

  const api = $fetch.create({
    baseURL: '<https://api.nuxt.com',>
    onRequest({ options }) {
      if (session.value?.token) {
        options.headers.set('Authorization', `Bearer ${session.value?.token}`)
      }
    }
  })

  return {
    provide: {
      api
    }
  }
})

This plugin can be used in your server routes to make authenticated requests to your external API Docs > Guide > Recipes > Custom useFetch (https://nuxt.com/docs/guide/recipes/custom-usefetch#custom-fetch). By using this approach, you can securely fetch HTML from your API and display it in your Nuxt application while handling authentication properly. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how i can use the plugin in the server route?

kapa.ai•3w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To use the plugin in a server route in Nuxt 3, you need to access it through the event object. However, it's important to note that plugins are primarily designed for use in the Vue part of your Nuxt app, not in the server routes. That being said, there is a way to access the runtime config in server routes, which can be used to achieve a similar result. Here's how you can modify your server route to use the runtime config for API calls: 1. First, update your nuxt.config.ts to include the necessary runtime config:

export default defineNuxtConfig({
  runtimeConfig: {
    apiSecret: process.env.API_SECRET,
    public: {
      apiBase: process.env.API_BASE
    }
  }
})

export default defineNuxtConfig({
  runtimeConfig: {
    apiSecret: process.env.API_SECRET,
    public: {
      apiBase: process.env.API_BASE
    }
  }
})

2. Then, in your server route, you can use the useRuntimeConfig() function to access these values:

// server/api/ticket/[id].ts
export default defineEventHandler(async (event) => {
  const config = useRuntimeConfig()
  const id = event.context.params.id

  // Use the runtime config for the API base and secret
  const response = await $fetch(`${config.public.apiBase}/api/tickets/${id}`, {
    headers: {
      'Authorization': `Bearer ${config.apiSecret}`
    }
  })

  return response
})

// server/api/ticket/[id].ts
export default defineEventHandler(async (event) => {
  const config = useRuntimeConfig()
  const id = event.context.params.id

  // Use the runtime config for the API base and secret
  const response = await $fetch(`${config.public.apiBase}/api/tickets/${id}`, {
    headers: {
      'Authorization': `Bearer ${config.apiSecret}`
    }
  })

  return response
})

This approach allows you to securely use your API credentials in server routes without exposing them to the client side. If you specifically need to use the plugin's functionality in a server route, you might consider moving that logic to a separate utility function that can be imported and used in both the plugin and the server route. For example:

// utils/api.ts
export const createApiInstance = (baseURL: string, getToken: () => string | null) => {
  return $fetch.create({
    baseURL,
    onRequest({ options }) {
      const token = getToken()
      if (token) {
        options.headers.set('Authorization', `Bearer ${token}`)
      }
    }
  })
}

// utils/api.ts
export const createApiInstance = (baseURL: string, getToken: () => string | null) => {
  return $fetch.create({
    baseURL,
    onRequest({ options }) {
      const token = getToken()
      if (token) {
        options.headers.set('Authorization', `Bearer ${token}`)
      }
    }
  })
}

Then you can use this in both your plugin and server route:

// plugins/api.ts
export default defineNuxtPlugin((nuxtApp) => {
  const { session } = useUserSession()
  const config = useRuntimeConfig()

  const api = createApiInstance(config.public.apiBase, () => session.value?.token)

  return {
    provide: {
      api
    }
  }
})

// server/api/ticket/[id].ts
import { createApiInstance } from '~/utils/api'

export default defineEventHandler(async (event) => {
  const config = useRuntimeConfig()
  const id = event.context.params.id

  const api = createApiInstance(config.public.apiBase, () => config.apiSecret)

  const response = await api(`/api/tickets/${id}`)

  return response
})

// plugins/api.ts
export default defineNuxtPlugin((nuxtApp) => {
  const { session } = useUserSession()
  const config = useRuntimeConfig()

  const api = createApiInstance(config.public.apiBase, () => session.value?.token)

  return {
    provide: {
      api
    }
  }
})

// server/api/ticket/[id].ts
import { createApiInstance } from '~/utils/api'

export default defineEventHandler(async (event) => {
  const config = useRuntimeConfig()
  const id = event.context.params.id

  const api = createApiInstance(config.public.apiBase, () => config.apiSecret)

  const response = await api(`/api/tickets/${id}`)

  return response
})

This approach allows you to reuse the same API logic in both client-side and server-side code while keeping your secrets secure Docs > Guide > Directory-structure > server (https://nuxt.com/docs/guide/directory-structure/server#runtime-config). Remember, when working with server routes, it's crucial to keep security in mind and avoid exposing sensitive information to the client side. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai is there a way to fetch the full html from an api?

kapa.ai•3w ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Yes, there is a way to fetch the full HTML from an API in Nuxt 3. You can use the useFetch composable or the $fetch utility to make the request and retrieve the HTML content. Here's how you can do it: 1. Using useFetch:

<script setup>
const { data: htmlContent } = await useFetch('/api/your-html-endpoint')
</script>

<template>
  <div v-html="htmlContent"></div>
</template>

<script setup>
const { data: htmlContent } = await useFetch('/api/your-html-endpoint')
</script>

<template>
  <div v-html="htmlContent"></div>
</template>

2. Using $fetch:

<script setup>
const htmlContent = ref('')

onMounted(async () => {
  htmlContent.value = await $fetch('/api/your-html-endpoint')
})
</script>

<template>
  <div v-html="htmlContent"></div>
</template>

<script setup>
const htmlContent = ref('')

onMounted(async () => {
  htmlContent.value = await $fetch('/api/your-html-endpoint')
})
</script>

<template>
  <div v-html="htmlContent"></div>
</template>

Both useFetch and $fetch are built-in Nuxt utilities that handle isomorphic fetching, meaning they work correctly in both server-side rendering and client-side navigation scenarios Docs > Getting-started > Data fetching (https://nuxt.com/docs/getting-started/data-fetching#the-need-for-usefetch-and-useasyncdata). If you need to make the request from a server route (for example, to proxy an external API), you can do so like this:

// server/api/html-content.ts
export default defineEventHandler(async (event) => {
  const config = useRuntimeConfig()
  
  const htmlContent = await $fetch('<https://external-api.com/html-endpoint',> {
    headers: {
      // Add any necessary headers here
    }
  })

  return htmlContent
})

// server/api/html-content.ts
export default defineEventHandler(async (event) => {
  const config = useRuntimeConfig()
  
  const htmlContent = await $fetch('<https://external-api.com/html-endpoint',> {
    headers: {
      // Add any necessary headers here
    }
  })

  return htmlContent
})

Then, in your component, you would fetch from this server route:

<script setup>
const { data: htmlContent } = await useFetch('/api/html-content')
</script>

<template>
  <div v-html="htmlContent"></div>
</template>

<script setup>
const { data: htmlContent } = await useFetch('/api/html-content')
</script>

<template>
  <div v-html="htmlContent"></div>
</template>

Remember to be cautious when rendering HTML content from an API, especially if it's from an untrusted source. You should sanitize the HTML to prevent potential XSS attacks. Also, note that fetching and rendering full HTML pages within your Nuxt app might not always be the best approach for performance and SEO. It's often better to structure your data and render it using Vue components. However, if you need to display full HTML content from an API, the above methods will work.
