Pull request overview

This PR converts social media syndication from Zapier to a custom GitHub Actions-based solution. The implementation automates posting blog content and link shares to multiple social platforms (LinkedIn, Mastodon, Twitter, Bluesky, Pinterest) using a combination of direct APIs and IFTTT webhooks. The workflow triggers after successful Netlify deployments via a GitHub repository dispatch event.

Key Changes:

GitHub Actions workflow with automated syndication to 5+ social platforms
Netlify plugin integration to trigger GitHub workflow on successful deploys
Smart caching system to prevent duplicate posts and only syndicate items published today
Feed enhancement to support custom social media text via twitter_text field

+	async ensureCacheDir() {
+		try {
+			await fs.mkdir(this.cacheDir, { recursive: true });
+		} catch (error) {
+			// Directory already exists or other error
+		}


The error handling silently ignores directory creation failures. If the directory creation fails for reasons other than "already exists" (e.g., permission issues), the error is swallowed. Consider logging the error or checking for specific error codes (e.g., EEXIST) to ensure only expected errors are ignored.

netlify.toml

+package = "netlify-plugin-github-dispatch"
+[plugins.inputs]
+repo = "aarongustafson/aaron-gustafson.com"
+token = "${GITHUB_ACCESS_TOKEN}"


The comment references GITHUB_ACCESS_TOKEN (line 27) but then suggests using either GITHUB_ACCESS_TOKEN or GITHUB_TOKEN (line 149 in SYNDICATION_SETUP.md). However, the actual Netlify function at .netlify/functions/syndicate-trigger.js uses GITHUB_TOKEN (line 43). This inconsistency will cause the integration to fail. Ensure all references use the same environment variable name.

Suggested change

token = "${GITHUB_ACCESS_TOKEN}"

token = "${GITHUB_TOKEN}"

+		const relatedUrl = link.external_url || link.url;
+
+		// Generate screenshot URL
+		const screenshotUrl = ContentProcessor.createScreenshotUrl(relatedUrl);


The screenshotUrl variable is generated but never used. It's created on line 71 but doesn't appear anywhere else in the function. Either remove this line if screenshots aren't needed for links, or pass it to the IFTTT webhooks or other platform integrations where it should be used.

+        run: |
+          npm install
+          # Install additional syndication dependencies
+          npm install axios cheerio html-to-text dotenv


Installing dependencies twice is inefficient. Line 46 runs npm install, and then line 48 installs axios cheerio html-to-text dotenv again. Since these packages are already in package.json (axios, cheerio, html-to-text), the second install is redundant. Remove line 48 or only install packages not in package.json.

Suggested change

npm install axios cheerio html-to-text dotenv

+3. Or use alternative services like:
+   - [URLBox](https://urlbox.io/)
+   - [Bannerbear](https://www.bannerbear.com/)
+   - [Htmlcsstoimage](https://htmlcsstoimage.com/)


The service name should be capitalized properly as "HTML/CSS to Image" or match their branding. The current format "Htmlcsstoimage" looks like a typo or incorrect capitalization.

The fallback IFTTT calls (lines 134-137 and 173-179) don't have error handling. If the fallback also fails, it will cause an unhandled promise rejection. Consider wrapping these fallback calls in try-catch blocks and logging any failures, since they're meant to be backup mechanisms.

The sample github-dispatch Netlify function sends a repository dispatch event to GitHub using process.env.GITHUB_TOKEN but does not authenticate or verify that incoming requests actually originate from GitHub/Netlify. An attacker can directly call this public function endpoint and trigger arbitrary repository_dispatch events against your repo using your token, potentially abusing any workflows bound to that event. Add authentication to this function (for example, verify a shared secret or GitHub webhook signature before calling fetch, and reject requests that fail validation) so only trusted callers can trigger dispatches.
