🎨 About This Theme

My link in bio Astro website is a clean, professional theme designed for creators, entrepreneurs, and professionals who want a centralised hub for their online presence. The theme focuses on simplicity, performance, and customisation.

I built it because I wanted a really fast and fun bio link that sends people to my social accounts, websites and blog posts.

You'd click a link in bio on Instagram and between the social media app's in-built browser being slow, internet being slow, and everything just being harder, the page would also be slow.

I built this to be fast, not just fast loading, but fast to get into and then equally as fast to get out of. There's no blog collections, no tracking, minimal scripting and CSS, and people smarter than me could probably make it faster.

Obviously the design is a bit esoteric. I was trying to make something different and weird and found inspiration in shopping recipets, takeaway menues, and the web of old.

SiteConfig.json Customisation Guide

This guide will help you customise the siteConfig.json file to personalise your link-in-bio website. The configuration file controls all the content and settings for your personal website.

Required Assets

Before customising the config, make sure you have:

• Profile Picture: Replace /src/assets/profile-picture.webp with your own image (keep the same filename)

Configuration Sections

The theme is configured through the src/siteConfig.json file. Here's what you can customise:

1. Basic Information

{
  "name": "Your Full Name",
  "bio": "A short bio that appears prominently on your site and is also used as the meta-description. Keep it to 110-160 characters.",
  "url": "https://yourdomain.com"
}

Fields to customise:

• name: Your full name as you want it displayed
• bio: A brief, engaging description of yourself (1-2 sentences, 110-160 characters.)
• url: Your website's primary URL

2. About Section

"about": {
  "title": "About [Your Name]",
  "content": "A longer description of who you are, what you do, and what makes you unique. This appears in a dedicated about section."
}

Customisation tips:

• Keep the title format consistent: "About [Your Name]"
• Write 2-3 sentences that capture your personality and work
• Use a conversational tone that matches your brand
• This is displayed towards the bottom of the page and can be a more in-depth bio.

3. Contact Information

"contact": {
  "email": "your@email.com",
  "ctaTitle": "GET IN TOUCH!"
}

Fields to customise:

• email: Your primary contact email
• ctaTitle: Call-to-action text for contact button (keep it energetic!)

4. Profile Picture

"profilePicture": "/profile-picture.webp"

To customise:

1. Replace the file at /src/assets/profile-picture.webp with your image
2. Keep the same filename and format (.webp recommended for performance)
3. Recommended size: 256x256px, square aspect ratio

5. Footer Barcode (Optional)

"footer": {
  "barcode": {
    "src": "/barcode.png",
    "alt": "Barcode",
    "width": 200,
    "height": 50
  }
}

To customise:

• Replace /public/barcode.png with your own image, or
• barcodesinc.com/generator is what I used to generate mine.

6. Recent Posts (RSS Feeds)

"recentPosts": {
  "enabled": true,
  "count": 30,
  "feeds": [
    "https://yourblog.com/rss",
    "https://anotherblog.com/feed.xml"
  ]
}

To customise:

• Set enabled to false if you don't want to show recent posts
• Adjust count for how many posts from across the feeds, in total, to display
• Replace the feeds array with your own RSS feed URLs
• Remove feeds you don't want to include

7. Social Media Icons

"iconLinks": [
  {
    "icon": "simple-icons:instagram",
    "url": "https://instagram.com/yourusername"
  },
  {
    "icon": "simple-icons:youtube",
    "url": "https://youtube.com/@yourusername"
  }
]

Available icons: Check the /src/icons/ folder for available icons, or use Simple Icons format (simple-icons:platform)

To customise:

• Replace URLs with your own social media profiles
• Add or remove platforms as needed
• For custom icons, add the SVG file to /src/icons/ and reference by filename

8. Custom Links

"customLinks": [
  {
    "title": "🚀 My Main Project",
    "url": "https://yourproject.com"
  },
  {
    "title": "📝 My Blog",
    "url": "https://yourblog.com"
  }
]

customisation tips:

• Use emojis to make links more visually appealing
• Order links by importance (most important first)
• Keep titles concise but descriptive

9. Referral Links (Optional)

"referralLinks": [
  {
    "title": "10% off Service Name",
    "url": "https://service.com/ref/yourcode"
  }
]

To customise:

• Add your referral links for services you recommend
• Include the discount/benefit in the title
• Remove this section entirely if you don't want referral links
• these links are published on the save.astro page at /save

Tips for Success

• Update site URL in astro.config.mjs: in the root of the project update the site URL in astro.config.mjs - all other config happens in the src/siteConfig.json file

• Keep it authentic: Write in your own voice

• Test locally: Make sure your JSON is valid

• Optimise images: Use WebP format for better performance

• Update regularly: Keep your links and information current

• Automated RSS Updates: To keep your RSS feeds fresh while maintaining a static, fast website, you can set up automated rebuilds using Cloudflare Pages deploy hooks triggered by GitHub Actions. Here's how:

  1. Set up Cloudflare Pages Deploy Hook:

     • Go to your Cloudflare Pages dashboard
     • Navigate to your project settings
     • Find "Build & deployments" → "Deploy hooks"
     • Create a new deploy hook and copy the webhook URL

  2. Configure GitHub Secrets:

     • In your GitHub repository, go to Settings → Secrets and variables → Actions
     • Add a new repository secret named CF_PAGES_WEBHOOK_URL
     • Paste your Cloudflare deploy hook URL as the value

  3. Customise the Schedule:

     • Edit the cron schedule in /.github/workflows/scheduled-rss-build.yml
     • The current setup rebuilds 3 times daily (6 AM, 2 PM, 10 PM Hobart time)
     • Adjust the cron expressions to match your preferred update frequency

  This approach keeps your site static and lightning-fast while ensuring RSS content stays current without manual intervention.

  There's a high chance you're smarter than me and you can find a better way to do this. I'm considering building the webhook call into my other blogs publishing process, so this page only builds when I publish a post.
