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

#

To hide the default language (in your case, de) from the URL while still supporting both en and de, you should:

Store your default language pages directly in src/pages/ (not in a /de/ subfolder).
Store your other language(s) in their own subfolders (e.g., /en/).
Configure Astro i18n with prefixDefaultLocale: false so that only non-default languages get a prefix in the URL.

Your folder structure should look like:

src/
  pages/
    about.astro         // German (default)
    index.astro         // German (default)
    en/
      about.astro       // English
      index.astro       // English

Your astro.config.mjs should include:

import { defineConfig } from "astro/config";
export default defineConfig({
  i18n: {
    locales: ["de", "en"],
    defaultLocale: "de",
    routing: {
      prefixDefaultLocale: false
    }
  }
});

With this setup:

URLs like /about and / will serve the default language (de).
URLs like /en/about and /en/ will serve English.

This is the recommended approach for hiding the default language from the URL in Astro’s built-in i18n system [Configure i18n routing].

If you are using custom helpers for navigation, ensure that your path generation logic also respects this setup, so that links for the default language do not include the /de prefix [Hide default language in the URL].

Let me know if you need an example of the helper function for generating URLs!

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

#

Given your folder structure:

src/
  pages/
    [lang]/
      index.astro
      [...slug].astro

and your requirement to hide the default language (de) from the URL, the knowledge sources indicate that Astro’s built-in i18n routing expects you to use a static folder structure for hiding the default locale from the URL. Specifically, you should place the default language pages directly in src/pages/ (not in a [lang] dynamic route), and only use subfolders (or dynamic routes) for non-default languages [Configure i18n routing][Hide default language in the URL].

With your current dynamic [lang] folder structure, Astro will always expect a language prefix in the URL, even for the default language. This means /de/ will appear in the URL for German, and /en/ for English.

To hide the default language from the URL:

Do not use a dynamic [lang] folder for the default language.
Place your default language pages (German) directly in src/pages/.
Use a subfolder (or dynamic route) only for the non-default language(s).

Example structure:

src/
  pages/
    index.astro         // German (default)
    [...slug].astro     // German (default)
    en/
      index.astro       // English
      [...slug].astro   // English

Astro config:

import { defineConfig } from "astro/config";
export default defineConfig({
  i18n: {
    locales: ["de", "en"],
    defaultLocale: "de",
    routing: {
      prefixDefaultLocale: false
    }
  }
});

Result:

/ and /foo → German (default)
/en/ and /en/foo → English

#

Summary:
With a [lang] dynamic route, you cannot hide the default language from the URL using Astro’s built-in i18n. You must use static routing for the default language at the root of src/pages/ to achieve this [Hide default language in the URL][routing: prefixDefaultLocale].

If you need fully dynamic language routing and want to hide the default language, you would have to implement custom routing logic, but the knowledge sources do not provide a supported way to do this with `[lang]` dynamic routes.

With your current folder structure:

src/
  pages/
    [lang]/
      index.astro
      [...slug].astro
    index.astro

Astro’s built-in i18n routing does not support hiding the default language from the URL when using a dynamic [lang] route. The knowledge sources specify that to hide the default language (e.g., de) from the URL, you must place your default language pages directly at the root of src/pages/ and only use subfolders (or dynamic routes) for non-default languages. Using a [lang] dynamic route will always require a language prefix in the URL, even for the default language [Hide default language in the URL][prefixDefaultLocale].

To achieve hidden default language URLs:

Place your German (default) pages at the root:
src/pages/index.astro and src/pages/[...slug].astro
Place your English pages in a subfolder:
src/pages/en/index.astro and src/pages/en/[...slug].astro
Set prefixDefaultLocale: false in your Astro config.

Resulting URLs:

/ and /foo → German (default)
/en/ and /en/foo → English

With your current `[lang]` dynamic route, this is not possible using Astro’s built-in i18n features.
If you need this behavior, you must restructure your pages as described above [Hide default language in the URL].

No, you do not need to duplicate your default language (de) into a de/ folder if you want to hide the default language from the URL.

According to the Astro documentation, to hide the default language from the URL, you should:

Place your default language (German) pages directly in src/pages/ (e.g., src/pages/index.astro, src/pages/[...slug].astro).
Place your other language(s) (e.g., English) in their own subfolders (e.g., src/pages/en/index.astro, src/pages/en/[...slug].astro).
Set prefixDefaultLocale: false in your Astro config.

This way, URLs like / and /about will serve German, and /en/ and /en/about will serve English.
You do not need to create a src/pages/de/ folder or duplicate your German pages there. In fact, doing so would defeat the purpose of hiding the default language from the URL [Hide default language in the URL].

If you use a `[lang]` dynamic route, you cannot hide the default language from the URL. The default language must be at the root level, not inside a `[lang]` folder, to achieve this behavior.

woeful ironBOT Jul 16, 2025, 6:39 PM

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

#

If you configure Astro i18n with defaultLocale: "de" and prefixDefaultLocale: false, and organize your files as recommended (default language pages at the root, other languages in subfolders), then:

The URL / will serve the German (default) content.
The URL /de will not exist—there will be no /de route generated, unless you explicitly create a src/pages/de/ folder and files, which is not recommended if you want to hide the default language from the URL.

So, you will only have / for German, and /en for English. There will not be both /de and / for German unless you duplicate your content, which is not necessary and not recommended for this setup [Hide default language in the URL][prefixDefaultLocale].

If you see `/de` in your URLs, it means your structure or config is not set up as described above.

@woeful iron if i have data in content/pages/en
content/pages/de

how can i get oonly de folder data

woeful ironBOT Jul 17, 2025, 4:54 AM

#

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

#

To get only the data from the de folder (e.g., content/pages/de), you can use Astro Content Collections and filter by the language in your query.

Assuming your collection is set up like this:

src/
  content/
    pages/
      en/
        ... // English content
      de/
        ... // German content

And your src/content.config.ts defines the collection:

import { defineCollection, z } from 'astro:content';

const pages = defineCollection({
  schema: z.object({
    title: z.string(),
    // ...other fields
  }),
});

export const collections = { pages };

You can fetch only the German (de) entries like this:

import { getCollection } from 'astro:content';

const dePages = await getCollection('pages', (entry) => entry.id.startsWith('de/'));

This will return only the entries from the de folder within your pages collection. The id property includes the subfolder path, so filtering with startsWith('de/') selects only German content [getCollection()].

If your structure or schema is different, you may need to adjust the filter accordingly.

}),
});

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

#

Yes, your defineCollection configuration is valid for setting up a content collection for pages using Markdown files in src/content/pages. The glob loader with the pattern "**/[^_]*.md" will include all Markdown files (excluding those starting with _) in any subdirectory of src/content/pages. Your schema uses Zod to validate the frontmatter fields, which is the recommended approach [Defining the collection schema].

Here’s a breakdown:

const pages = defineCollection({
  loader: glob({ pattern: "**/[^_]*.md", base: "src/content/pages" }),
  schema: z.object({
    title: z.string(),
    slug: z.string(),
    metaTitle: z.string().optional(),
    metaDescription: z.string().optional(),
    description: z.string().optional(),
    canonicalUrl: z.string().optional(),
    ogImage: z.string().optional(),
    blocks: z.array(z.any()).optional(),
  }),
});

loader: Uses the glob loader to match all Markdown files (except those starting with _) in src/content/pages and its subfolders [glob() loader].
schema: Defines the expected frontmatter fields using Zod, which is required for type safety and validation [Defining the collection schema].

This setup will work for organizing and validating your page content as described in the Astro documentation.

@woeful iron Yes but still iam noit getting "en" and "de" in "id" and when i get the getcollection("pages") it only show pages for en

woeful ironBOT Jul 17, 2025, 5:02 AM

#

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

#

If you are not seeing "en" and "de" in the id when using getCollection("pages"), and only English pages are returned, the most likely cause is the way your files are organized or how the glob loader is configured.

According to the Astro documentation, the id for each entry is generated based on the file path relative to the base directory you specify in the glob loader. If your structure is:

src/
  content/
    pages/
      en/
        about.md
      de/
        about.md

And your loader is:

loader: glob({ pattern: "**/[^_]*.md", base: "src/content/pages" })

Then, the id for each entry should be:

en/about
de/about

If you are only seeing English pages, please check:

File Placement: Ensure your German files are actually in src/content/pages/de/ and not in a different location or with a leading underscore (which would be excluded by your pattern).
File Names: Make sure the German files do not start with an underscore (_), as your pattern excludes those.
Pattern and Base: Your pattern and base look correct for this structure, so if the files exist and match the pattern, they should be included.

If you have confirmed the above and still do not see the German entries, the knowledge sources do not provide further troubleshooting steps for this specific issue. You may want to double-check your project structure and file naming, as the described setup should work according to the documentation [Defining custom IDs][glob() loader].

If you need to filter only German entries, you can do:

#

const dePages = await getCollection('pages', (entry) => entry.id.startsWith('de/'));

as described in the documentation [Filtering collection queries].

If this still does not work, the knowledge sources do not contain enough information to diagnose further.

Given your directory structure:

src/content/pages/
├── de/
│   ├── contact.md
│   ├── ...
└── en/
    ├── contact.md
    ├── ...

and your defineCollection setup:

const pages = defineCollection({
  loader: glob({ pattern: "**/[^_]*.md", base: "src/content/pages" }),
  schema: z.object({
    // your schema fields
  }),
});

You should see both de/ and en/ in the id of each entry. For example, the id for src/content/pages/de/contact.md should be de/contact, and for src/content/pages/en/contact.md it should be en/contact [Defining custom IDs].

If you are only seeing English pages, please check the following based on the knowledge sources:

File Names:
Make sure none of your German files start with an underscore (_), as your pattern excludes those.
Pattern and Base:
Your pattern and base are correct for this structure. The pattern "**/[^_]*.md" will match all .md files in any subdirectory of src/content/pages that do not start with _ [glob() loader].
Querying the Collection:
When you use getCollection('pages'), you should get all entries from both de and en folders.
To get only German entries, use:
```
const dePages = await getCollection('pages', (entry) => entry.id.startsWith('de/'));
```
This will filter for only the German content [Filtering collection queries].

If you have confirmed all of the above and still do not see the German entries, the knowledge sources do not provide further troubleshooting steps for this specific issue. The described setup should work according to the official Astro documentation.

The error message you are seeing:

The argument 'path' must be a string, Uint8Array, or URL without null bytes. Received '/Users/amir/Documents/GitHub/i18n-decap/\x00astro-entry:/Users/amir/Documents/GitHub/i18n-decap/src/components/tsconfig.json'

does not appear in the official Astro error reference or troubleshooting documentation. The knowledge sources do not contain a direct explanation or solution for this specific error.

However, based on the Astro troubleshooting guide, such errors can sometimes be related to:

Incorrect import paths (e.g., importing a file that does not exist or has a typo in the path).
Attempting to import a non-component file (like tsconfig.json) as a module in your component.
Misconfiguration in your project structure or build process.

What you can check:

Ensure you are not importing tsconfig.json or any configuration file in your .astro or component files.
Double-check your import statements in LanguageSelector.astro and other related files for typos or incorrect paths.
Make sure your tsconfig.json is only in the root of your project and not inside src/components/.

If the issue persists after these checks, the knowledge sources do not provide enough information to give a more specific answer. You may want to consult the Astro community or open an issue on the Astro GitHub repository for further assistance.
