Is there a built in way or convention for converting a string (e.g. a post title) to a URL slug?

Convert String to URL slug

In Astro, every content entry generates a URL-friendly slug property from its file id when using type: 'content'. This slug is used to query the entry directly from your collection and is also useful when creating new pages and URLs from your content.
You can override an entry’s generated slug by adding your own slug property to the file frontmatter. This is similar to the “permalink” feature of other web frameworks. slug is a special, reserved property name that is not allowed in your custom collection schema and will not appear in your entry’s data property.
Here's an example of how you can define a custom slug in the frontmatter of your content file:
---
title: My Blog Post
slug: my-custom-slug/supports/slashes
---
Your blog post content here.
In this example, the URL for this blog post would end with /my-custom-slug/supports/slashes instead of the default slug generated from the file id.
Remember that content collection entries must have unique slugs. Duplicates are often caused by the slug frontmatter property. If you have multiple entries with the same slug, you will encounter a Duplicate content entry slug error.
For more information, you can refer to the Astro documentation on defining custom slugs (https://docs.astro.build/en/guides/content-collections#defining-custom-slugs) and the Astro API reference for the slug property (https://docs.astro.build/en/reference/api-reference#slug).

@halcyon merlin this for a tags page but the tag names aren't curated. so i can't use the file id. is there a different convention?

Let me check the knowledge base for you. One moment! :books:
Astro doesn't provide a built-in way to convert a string into a URL slug. However, you can create a function to convert your tag names into URL-friendly slugs. This function would typically convert the string to lowercase, replace spaces with hyphens, and remove any special characters.
Here's a simple example of how you might create such a function in JavaScript:
function createSlug(string) {
return string.toLowerCase().replace(/[^a-z0-9]+/g, '-').replace(/(^-|-$)/g, '');
}
You can then use this function to convert your tag names into slugs when creating links:
<BaseLayout pageTitle={pageTitle}>
<div class="tags">
{tags.map((tag) => (
<p class="tag"><a href={`/tags/${createSlug(tag)}`}>{tag}</a></p>
))}
</div>
</BaseLayout>
Please note that this is a simple example and might not cover all edge cases. You might want to use a library like slugify (https://www.npmjs.com/package/slugify) for more robust slug generation.

@halcyon merlin can you provide an example with slugify?

Sure, you can use the slugify function from the slugify package to convert a string into a URL-friendly slug. Here's an example of how you might use it:
First, install the slugify package in your project:
npm install slugify
Then, you can import the slugify function and use it to convert your tag names into slugs:
import slugify from 'slugify';
// ...
<BaseLayout pageTitle={{pageTitle}}>
<div class="tags">
{{tags.map((tag) => (
<p class="tag"><a href={{`/tags/${{slugify(tag, {lower: true})}}`}}>{{tag}}</a></p>
))}}
</div>
</BaseLayout>
In this example, the slugify function converts the tag name into a URL-friendly slug. The {lower: true} option makes the slug lowercase.
