description: How you can make AstroPaper theme absolutely yours.
---
AstroPaper is a highly customizable Astro blog theme. With AstroPaper, you can customize everything according to your personal taste. This article will explain how you can make some customizations easily in the config file.
## Table of contents
## Configuring SITE
The important configurations resides in `src/config.ts` file. Within that file, you'll see the `SITE` object where you can specify your website's main configurations.
During development, it's okay to leave `SITE.website` empty. But in production mode, you should specify your deployed url in `SITE.website` option since this will be used for canonical URL, social card URL etc.. which are important for SEO.
```js
// file: src/config.ts
export const SITE = {
website: "https://astro-paper.pages.dev/", // replace this with your deployed domain
author: "Sat Naing",
profile: "https://satnaing.dev/",
desc: "A minimal, responsive and SEO-friendly Astro blog theme.",
title: "AstroPaper",
ogImage: "astropaper-og.jpg",
lightAndDarkMode: true,
postPerIndex: 4,
postPerPage: 4,
scheduledPostMargin: 15 * 60 * 1000, // 15 minutes
showArchives: true,
showBackButton: true, // show back button in post detail
editPost: {
enabled: true,
text: "Suggest Changes",
url: "https://github.com/satnaing/astro-paper/edit/main/",
},
dynamicOgImage: true, // enable automatic dynamic og-image generation
} as const;
```
Here are SITE configuration options
| Options | Description |
| --------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `website` | Your deployed website URL |
| `author` | Your name |
| `profile` | Your personal/portfolio website URL which is used for better SEO. Put `null` or empty string `""` if you don't have any. |
| `desc` | Your site description. Useful for SEO and social media sharing. |
| `title` | Your site name |
| `ogImage` | Your default OG image for the site. Useful for social media sharing. OG images can be an external image URL or they can be placed under `/public` directory. |
| `lightAndDarkMode` | Enable or disable `light & dark mode` for the website. If disabled, primary color scheme will be used. This option is enabled by default. |
| `postPerIndex` | The number of posts to be displayed at the home page under `Recent` section. |
| `postPerPage` | You can specify how many posts will be displayed in each posts page. (eg: if you set `SITE.postPerPage` to 3, each page will only show 3 posts per page) |
| `scheduledPostMargin` | In Production mode, posts with a future `pubDatetime` will not be visible. However, if a post's `pubDatetime` is within the next 15 minutes, it will be visible. You can set `scheduledPostMargin` if you don't like the default 15 minutes margin. |
| `showArchives` | Determines whether to display the `Archives` menu (positioned between the `About` and `Search` menus) and its corresponding page on the site. This option is set to `true` by default. |
| `showBackButton` | Determines whether to display the `Go back` button in each blog post. |
| `editPost` | This option allows users to suggest changes to a blog post by providing an edit link under blog post titles. This feature can be disabled by setting `SITE.editPost.enabled` to `false`. |
| `dynamicOgImage` | This option controls whether to [generate dynamic og-image](https://astro-paper.pages.dev/posts/dynamic-og-image-generation-in-astropaper-blog-posts/) if no `ogImage` is specified in the blog post frontmatter. If you have many blog posts, you might want to disable this feature. See the [trade-off](https://astro-paper.pages.dev/posts/dynamic-og-image-generation-in-astropaper-blog-posts/#trade-off) for more details. |
## Configuring locale
You can configure the default locale used for the build (e.g., date format in the post page), and for the rendering in browsers (e.g., date format in the search page). You can update locale in `src/constants.ts` file.
```js
// file: src/constants.ts
export const LOCALE = {
lang: "en", // html lang code. Set this empty and default will be "en"
langTag: ["en-EN"], // BCP 47 Language Tags. Set this empty [] to use the environment default
} as const;
```
`LOCALE.lang` will be used as HTML ISO Language code in ``. If you don't specify this, default fallback will be set to `en`.
`LOCALE.langTag` is used as [datetime locale](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString#locales). For this, you can specify an array of locales for fallback languages. Leave `LOCALE.langTag` empty `[]` to use the environment default at _build-_ and _run-time_.
## Configuring logo or title
Prior to AstroPaper v5, you can update your site name/logo in `LOGO_IMAGE` object inside `src/config.ts` file. However, in AstroPaper v5, this option has been removed in favor of Astro's built-in SVG and Image components.
There are 3 options you can do:
### Option 1: SITE title text
This is the easiest option. You just have to update `SITE.title` in `src/config.ts` file.
### Option 2: Astro's SVG component
You might want to use this option if you want to use an SVG logo.
- First add an SVG inside `src/assets` directory. (eg: `src/assets/dummy-logo.svg`)
- Then import that SVG inside `src/components/Header.astro`
```astro
---
// other imports
import DummyLogo from "@/assets/dummy-logo.svg";
---
```
- Finally, replace `{SITE.title}` with imported logo.
```html
```
The best part of this approach is that you can customize your SVG styles as needed. In the example above, you can see how the SVG logo color can be inverted in dark mode.
### Option 3: Astro's Image component
If your logo is an image but not SVG, you can use Astro's Image component.
- Add your logo inside `src/assets` directory. (eg: `src/assets/dummy-logo.png`)
- Import `Image` and your logo in `src/components/Header.astro`
```astro
---
// other imports
import { Image } from "astro:assets";
import dummyLogo from "@/assets/dummy-logo.png";
---
```
- Then, replace `{SITE.title}` with imported logo.
```html
```
With this approach, you can still adjust your image's appearance using CSS classes. However, this might not always fit what you want. If you need to display different logo images based on light or dark mode, check how light/dark icons are handled inside the `Header.astro` component.
## Configuring social links
You can configure social links in `SOCIALS` object inside `src/constants.ts`.
```ts
export const SOCIALS = [
{
name: "Github",
href: "https://github.com/satnaing/astro-paper",
linkTitle: ` ${SITE.title} on Github`,
icon: IconGitHub,
},
{
name: "X",
href: "https://x.com/username",
linkTitle: `${SITE.title} on X`,
icon: IconBrandX,
},
{
name: "LinkedIn",
href: "https://www.linkedin.com/in/username/",
linkTitle: `${SITE.title} on LinkedIn`,
icon: IconLinkedin,
},
{
name: "Mail",
href: "mailto:yourmail@gmail.com",
linkTitle: `Send an email to ${SITE.title}`,
icon: IconMail,
},
] as const;
```
## Configuring share links
You can configure share links in `SHARE_LINKS` object inside `src/constants.ts`.
