Hi @cyan timber. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
To get the title from a markdown file in Astro, you can use the data property of an entry. The data property contains the frontmatter of your markdown file. Here's an example of how you can do this:
---import { getCollection } from 'astro:content';
export async function getStaticPaths() {
const blogEntries = await getCollection('posts');
return blogEntries.map(entry => ({
params: { slug: entry.slug },
props: { entry },
}));
}
const { entry } = Astro.props;
const { Content } = await entry.render();
---
<h1>{entry.data.title}</h1>
<Content />
In this example, entry.data.title will give you the title from the frontmatter of your markdown file. The getCollection function is used to get all entries from the 'posts' collection, and for each entry, a page is generated with the slug as a parameter and the entry as a prop. The title is then accessed from the entry's data.
Please note that this example assumes that your markdown files are part of a content collection in Astro and that they have a title field in their frontmatter.

@lilac rapids how to get the metadata from a single markdown file
lilac rapidsBOT
Let me check the knowledge base for you. One moment! :books:
To get the metadata (frontmatter) from a single markdown file in Astro, you can use the import statement. Here's an example of how you can do this:
---import * as myPost from '../pages/post/my-post.md';---
<h1>{myPost.frontmatter.title}</h1>
<p>Written by: {myPost.frontmatter.author}</p>
In this example, myPost.frontmatter.title and myPost.frontmatter.author will give you the title and author from the frontmatter of your markdown file respectively.
Please note that this example assumes that your markdown file has a title and author field in its frontmatter.

@lilac rapids how to use astro remote
lilac rapidsBOT
Let me check the knowledge base for you. One moment! :books:
Astro provides a --remote flag that allows you to connect to your hosted Studio database. This flag is used when running the dev or build commands and is particularly useful for production deploys, as it provides both readable and writable access to your Studio database.
Here's how you can use it:
# Build with a remote connection
astro build --remote
# Develop with a remote connection
astro dev --remote
Please be careful when using --remote in development, as it connects to a live production database, and all inserts, updates, or deletions will be persisted.
To use a remote connection, you will need an app token to authenticate with Studio. You can create an app token from your Studio project dashboard by navigating to the Settings tab and selecting Tokens. Once you have the token, apply it as an environment variable / environment secret in your deployment platform using the name ASTRO_STUDIO_APP_TOKEN.
When you’re ready to deploy, you can configure your build command to connect with Studio using the --remote flag. For example, in your project’s package.json, you can set the build script like this:
{ "scripts": { "build": "astro build --remote" }}

@lilac rapids how to generate a table of contents from import markdown file
lilac rapidsBOT
Let me check the knowledge base for you. One moment! :books:
To generate a table of contents from an imported markdown file in Astro, you can use the remark-toc plugin. This plugin auto-generates a table of contents from your markdown headings.
First, you need to install the plugin:
npm install remark-toc
Then, you can add it to your Astro configuration:
import { defineConfig } from 'astro/config';
import remarkToc from 'remark-toc';
export default defineConfig({
markdown: {
remarkPlugins: [remarkToc],
},
});
By default, remarkToc requires a "ToC" or "Table of Contents" heading (case-insensitive) on the page to show the table of contents.
Please note that this will apply to all markdown and MDX files in your Astro project. If you want to apply it to a specific markdown file, you would need to process that file with remark-toc separately.

@lilac rapids generate toc from imported markdown in starlight
lilac rapidsBOT
Let me check the knowledge base for you. One moment! :books:
In Starlight, the framework automatically generates a table of contents from your markdown headings. The page title is used as a top-level heading and an "Overview" heading is included at the top of each page's table of contents.
For example, if you have a markdown file with the following content:
---
title: My page of content
description: How to use Starlight's built-in anchor links
---
## Introduction
I can link to **my conclusion** (#conclusion) lower on the same page.
## Conclusion
Starlight will automatically generate a table of contents with "Introduction" and "Conclusion" as entries.
You can also customize the heading levels to be included in the table of contents by setting the tableOfContents field in the frontmatter of your markdown file:
---
title: Page with only H2s in the table of contents
tableOfContents:
minHeadingLevel: 2
maxHeadingLevel: 2
---
In this example, only H2 headings will be included in the table of contents.

@lilac rapids how to pass table of contents as props
lilac rapidsBOT
Let me check the knowledge base for you. One moment! :books:
In Astro, you can pass the table of contents as props to a component. However, the specific method to do this would depend on the structure of your project and how you're generating the table of contents.
For instance, if you're using Starlight, it provides a headings prop that contains an array of all Markdown headings extracted from the current page. You can pass this prop to a component to create a table of contents. Here's an example:
---
import TableOfContents from '../components/TableOfContents.astro';
const { headings } = Astro.props;
---
<TableOfContents headings={headings} />
In this example, TableOfContents is a component that takes a headings prop and generates a table of contents. The headings prop is an array of objects, each with a depth (the heading level), slug (the heading ID), and text (the heading text).
Please note that this example assumes that you have a TableOfContents component that can generate a table of contents from an array of headings.

@lilac rapids import markdown and render it to html
lilac rapidsBOT
Let me check the knowledge base for you. One moment! :books:
In Astro, you can import a Markdown file and render it to HTML using the Content component. Here's an example of how you can do this:
---import {Content as MyPost} from '../posts/my-post.md';---
<MyPost />
In this example, MyPost is the Content component imported from a markdown file. When you use this component in your Astro file, it will render the markdown content as HTML.
You can also import and render MDX content, which allows you to use JSX-like syntax and import other components within your markdown. Here's an example:
---import {Content, components} from '../content.mdx';
import Heading from '../Heading.astro';---
<Content components={{...components, h1: Heading }} />
In this example, a custom h1 component is used for the # syntax in the MDX content.

@lilac rapids import markdown file and get headings
lilac rapidsBOT
Let me check the knowledge base for you. One moment! :books:
In Astro, you can import a Markdown file and get its headings using the getHeadings function. Here's an example of how you can do this:
---import * as myPost from '../pages/post/my-post.md';---
<h1>{{myPost.frontmatter.title}}</h1>
<ul>
{myPost.getHeadings().map(heading => (
<li><a href={`#${heading.slug}`}>{heading.text}</a></li>
))}
</ul>
In this example, myPost.getHeadings() returns an array of all headings (i.e., h1 to h6 elements) in the file. Each heading's slug corresponds to the generated ID for a given heading and can be used for anchor links. The map function is used to create a list item for each heading.
Please note that getHeadings is an async function, so if you're using it outside of the Astro component, you'll need to await its result.

@lilac rapids fix ```
const yolo = Astro.glob("/src/content/docs/glossary/*.md");
const test = yolo.map((file) => ({
depth: 2,
slug: file.title,
text: file.title,
}));
Let me check the knowledge base for you. One moment! :books:
The Astro.glob function is asynchronous, so you need to use the await keyword to get the result. Also, the title is located in the frontmatter of each file. Here's how you can fix your code:
---
const files = await Astro.glob("/src/content/docs/glossary/*.md");
const test = files.map((file) => ({
depth: 2,
slug: file.frontmatter.title,
text: file.frontmatter.title,
}));
---
In this example, await Astro.glob("/src/content/docs/glossary/*.md") returns an array of all markdown files in the specified directory. Each file's frontmatter.title is used for the slug and text fields.
Please note that this example assumes that your markdown files have a title field in their frontmatter.

Let me check the knowledge base for you. One moment! :books:
Your code seems to be correct in terms of syntax and logic. It imports markdown files from a directory, extracts the title and filename from each file, groups the files by the first letter of the title, and generates a table of contents and a list of links to the files.
However, there's a small mistake in the way you're accessing the filename object in the map function. The filename object doesn't have file and frontmatter properties. Instead, you should use filename.url to get the file path and filename.data.title to get the title. Here's the corrected code:
---
import StarlightPage from "@astrojs/starlight/components/StarlightPage.astro";
interface File {
fileBase: string;
title: string;
}
const importedFiles = await Astro.glob("/src/content/docs/glossary/*.md");
const files = importedFiles.map((filename) => {
const filePath = filename.url;
const fileBase = filePath.toString().split("/").pop()?.split(".").shift();
const title = filename.data.title;
return { fileBase, title };
});
const sections = files.reduce((acc: { [key: string]: File[] }, file: File) => {
const firstLetter = file.title.charAt(0).toUpperCase();
if (!acc[firstLetter]) {
acc[firstLetter] = [];
}
acc[firstLetter].push(file);
return acc;
}, {});
const headings = Object.entries(sections).map((section: [string, File[]]) => ({
depth: 2,
slug: section[0],
text: section[0],
}));
---<StarlightPage frontmatter={{ title: "Glossary" }} headings={headings}>
{
Object.entries(sections).map((section: [string, File[]]) => (
<>
<h2 id={section[0]}>{section[0]}</h2>
<ul>
{section[1].map((file: File) => (
<li>
<a href={"/qbittorrent-nox-static/glossary/" + file.fileBase}>
{file.title}
</a>
</li>
))}
</ul>
</>
))
}
</StarlightPage>
Please note that this example assumes that your markdown files have a `title` field in their frontmatter.
