We’ve updated the logic for automatic OG image generation, making it even more reliable and efficient. Besides, it now supports special characters in post titles, ensuring accurate, flexible and eye-catching social media previews.

SITE.ogImage is now optional. If it is not specified, AstroPaper will automatically generate an OG image using SITE.title, SITE.desc and

Upgrade to AstroPaper v3

This section is only for those who want to upgrade AstroPaper v3 from the older versions.

This section will help you migrate from AstroPaper v2 to AstroPaper v3.

Before reading the rest of the section, you might also want to check this article for upgrading dependencies and AstroPaper.

In this release, a lot of changes have been made_ replacing old Astro APIs with newer APIs, bug fixes, new features etc. Thus, if you are someone who didn’t make customization very much, you should follow this approach.

Step 1: Keep all your updated files

It’s important to keep all the files which have been already updated. These files include

/* file: /src/styles/base.css */
@layer base {
  /* Other Codes */
  ::-webkit-scrollbar-thumb:hover {
    @apply bg-skin-card-muted;

  /* Old code
  code {
    white-space: pre;
    overflow: scroll;

  /* New code */
  blockquote {
    word-wrap: break-word;
  pre > code {
    white-space: pre;

@layer components {
  /* other codes */

Step 1: Replace everything else with AstroPaper v3

In this step, replace everything_ except above files/directories (plus your customized files/directories)_ with AstroPaper v3.

Step 3: Schema Updates

Keep in mind that /src/content/_schemas.ts has been replaced with /src/content/config.ts.

Besides, there is no longer BlogFrontmatter type exported from /src/content/config.ts.

Therefore, all the BlogFrontmatter type inside files need to be updated with CollectionEntry<"blog">["data"].

For example: src/components/Card.tsx

// AstroPaper v2
import type { BlogFrontmatter } from "@content/_schemas";

export interface Props {
  href?: string;
  frontmatter: BlogFrontmatter;
  secHeading?: boolean;
// AstroPaper v3
import type { CollectionEntry } from "astro:content";

export interface Props {
  href?: string;
  frontmatter: CollectionEntry<"blog">["data"];
  secHeading?: boolean;

Option 2: Upgrade using Git

This approach is not recommended for most users. You should do the “Option 1” if you can. Only do this if you know how to resolve merge conflicts and you know what you’re doing.

Actually, I’ve already written a blog post for this case and you can check out here.
