sharepost

What it does

On every publish, generates share URLs for Twitter/X, LinkedIn, WhatsApp, Bluesky, and email and writes them topost.data.metadata.shareUrls. ShipsShareButtons.astro with four variants. No third-party JavaScript, no tracking.

Install

Register

Open astro.config.mjs at the root of your Astro project. Import the plugin at the top, then add it to the pluginsarray of the emdash() integration - the one that sits inside Astro's top-level integrations array:

import { defineConfig } from "astro/config"
import emdash from "emdash/astro"
import { sharepostPlugin } from "@plugdash/sharepost"

export default defineConfig({
  integrations: [
    emdash({
      plugins: [
        sharepostPlugin({ via: "abhinavs" }),
      ],
    }),
  ],
})

The via option is your Twitter/X handle (without the @). It appears in the pre-filled tweet text.

Add the component

---
import ShareButtons from "@plugdash/sharepost/ShareButtons.astro"
---
<ShareButtons post={post} />
