#Getting the base path at build time without importing the entire config.

Is it possible for me to get my base path at build time without having to import the entire configuration? I am using this in a TSX component, which is placed inside a .astro component.

Hi @worthy ridge. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Yes, you can get your base path at build time without importing the entire configuration. Astro exposes the base path via the environment variable import.meta.env.BASE_URL, which is determined by your base config option. This variable is available in your components, including TSX components, and you do not need to import the full config to access it:

const basePath = import.meta.env.BASE_URL;

You can use this directly in your TSX component, even when it is used inside a .astro component. This approach is recommended for accessing the base path at build time in both server and client code, as long as you are not inside the Astro config file itself (where .env files are not loaded) Using environment variables Default environment variables.

If you need more type safety or IntelliSense, you can also extend the ImportMetaEnv interface in a src/env.d.ts file, but this is optional for basic usage.

@lilac arch I'm getting this error in my Astro config as well:

Cannot find module 'astro/config' or its corresponding type declarations.
There are types at 'c:/Users/KT/git/KTrain5169/neuro-sdk-docs/node_modules/astro/dist/config/entrypoint.d.ts', but this result could not be resolved under your current 'moduleResolution' setting. Consider updating to 'node16', 'nodenext', or 'bundler'.ts(2307)

Let me check the knowledge base for you again. One moment! :books:

The error message you are seeing:

Cannot find module 'astro/config' or its corresponding type declarations.
There are types at ... but this result could not be resolved under your current 'moduleResolution' setting. Consider updating to 'node16', 'nodenext', or 'bundler'.ts(2307)

suggests that your TypeScript configuration's moduleResolution setting is not compatible with how Astro exposes its types.

Solution:
Update your tsconfig.json to use a compatible moduleResolution setting, such as "node16", "nodenext", or "bundler". For example:

{
  "compilerOptions": {
    "moduleResolution": "node16"
  }
}

This change aligns with how Astro's types are structured and should resolve the import error for astro/config TypeScript Guide.

If you are using one of Astro's provided tsconfig templates (base, strict, or strictest), they already include the recommended settings. You can extend one of these templates in your tsconfig.json:

{
  "extends": "astro/tsconfigs/base"
}

For more details, see the TypeScript setup guide.

@lilac arch Also, how do I apply a site-wide banner in Starlight?

lilac archBOT
#

Let me check the knowledge base for you again. One moment! :books:

#

To apply a site-wide banner in Starlight, you can use the banner frontmatter field in your Markdown or MDX files. However, based on the knowledge sources, the banner field is applied per page by adding it to the frontmatter of each page:

---
title: Page with a banner
banner:
  content: |
    We just launched something cool!
    <a href="<https://example.com">Check> it out</a>
---

This will display an announcement banner at the top of that specific page Banner frontmatter reference.

Site-wide banner:
The knowledge sources do not explicitly mention a built-in way to apply a banner globally to all pages at once. To achieve a site-wide banner, you would need to add the banner frontmatter to each page individually, or consider overriding the Banner component to inject your desired content globally. However, the exact steps for a global override are not detailed in the provided sources.

If you need a truly global banner, you may want to look into overriding the Banner component, but the knowledge sources do not provide a step-by-step guide for this approach.

In summary:

  • Use the banner frontmatter for per-page banners.
  • For a site-wide banner, the knowledge sources do not provide a direct, built-in method. You may need to use component overrides, but details are not included in the sources provided.

@lilac arch one more question: how do I enable embeds on my Starlight site?

lilac archBOT
#

Let me check the knowledge base for you again. One moment! :books:

#

I'm sorry, but the knowledge sources do not explicitly mention how to enable or configure embeds on a Starlight site. While there are references to using components (including for things like YouTube embeds) in Starlight documentation, there are no detailed instructions or official guidance in the provided sources about enabling a general "embed" feature or plugin for Starlight sites.

If you are looking to embed specific content (like videos or social posts), you may be able to use Astro or Starlight components within your Markdown, MDX, or Markdoc files, as described in the Using components guide. However, for a dedicated "embeds" feature or plugin, the knowledge sources do not provide enough information to give a confident answer.
