CODE SNIPPETS FOR IMMEDIATE USE

1. Fetch GitHub Activity (Last 24h)

// lib/github-activity.ts
import { Octokit } from "octokit";
 
interface ActivityData {
  commits: any[];
  pullRequests: any[];
  issues: any[];
}
 
export async function get24hActivity(
  owner: string,
  repo: string,
  token: string
): Promise<ActivityData> {
  const octokit = new Octokit({ auth: token });
  const since = new Date(Date.now() - 24 * 60 * 60 * 1000).toISOString();
 
  try {
    const [commits, pullRequests, issues] = await Promise.all([
      octokit.rest.repos.listCommits({
        owner,
        repo,
        since,
        per_page: 100,
      }),
      octokit.rest.pulls.list({
        owner,
        repo,
        state: "all",
        sort: "updated",
        direction: "desc",
        per_page: 100,
      }),
      octokit.rest.issues.listForRepo({
        owner,
        repo,
        since,
        per_page: 100,
      }),
    ]);
 
    // Filter PRs updated in last 24h
    const recentPRs = pullRequests.data.filter(
      (pr) => new Date(pr.updated_at) > new Date(since)
    );
 
    return {
      commits: commits.data,
      pullRequests: recentPRs,
      issues: issues.data,
    };
  } catch (error) {
    console.error("GitHub API error:", error);
    throw error;
  }
}

2. Generate AI Summary with Claude

// lib/summarize.ts
import Anthropic from "@anthropic-ai/sdk";
 
interface SummaryInput {
  commits: any[];
  pullRequests: any[];
  issues: any[];
}
 
export async function generateDailyDigest(
  data: SummaryInput
): Promise<string> {
  const anthropic = new Anthropic({
    apiKey: process.env.ANTHROPIC_API_KEY,
  });
 
  const commitSummary = data.commits
    .map((c) => `- ${c.commit.message} (by ${c.commit.author.name})`)
    .join("\n");
 
  const prSummary = data.pullRequests
    .map((pr) => `- ${pr.title} (#${pr.number}) - ${pr.state}`)
    .join("\n");
 
  const issueSummary = data.issues
    .map((i) => `- ${i.title} (#${i.number}) - ${i.state}`)
    .join("\n");
 
  const prompt = `You are a technical writer creating a daily development digest.
 
COMMITS (last 24h):
${commitSummary || "No commits"}
 
PULL REQUESTS (updated last 24h):
${prSummary || "No pull requests"}
 
ISSUES (created/updated last 24h):
${issueSummary || "No issues"}
 
Generate a concise daily digest with:
1. Highlights (max 3 key points)
2. Key Changes (categorized: features, bugs, refactors)
3. Metrics (number of commits, PRs, issues)
4. Action Items (if any blockers or urgent reviews)
 
Keep it positive, concise, and actionable. Use bullet points.`;
 
  const message = await anthropic.messages.create({
    model: "claude-sonnet-4-20250514",
    max_tokens: 1024,
    messages: [{ role: "user", content: prompt }],
  });
 
  return message.content[0].text;
}

3. Send Email Digest with Resend

// lib/send-email.ts
import { Resend } from "resend";
 
const resend = new Resend(process.env.RESEND_API_KEY);
 
interface EmailOptions {
  to: string;
  subject: string;
  summary: string;
  repoName: string;
}
 
export async function sendDigestEmail(options: EmailOptions) {
  const html = `
<!DOCTYPE html>
<html>
<head>
  <style>
    body { font-family: -apple-system, BlinkMacSystemFont, 'Segoe UI', sans-serif; }
    .container { max-width: 600px; margin: 0 auto; padding: 20px; }
    .header { background: #24292e; color: white; padding: 20px; border-radius: 8px 8px 0 0; }
    .content { background: #f6f8fa; padding: 20px; border-radius: 0 0 8px 8px; }
    .summary { white-space: pre-wrap; line-height: 1.6; }
    .footer { margin-top: 20px; font-size: 12px; color: #666; }
  </style>
</head>
<body>
  <div class="container">
    <div class="header">
      <h1>Daily Dev Digest</h1>
      <p>${options.repoName}</p>
    </div>
    <div class="content">
      <div class="summary">${options.summary}</div>
    </div>
    <div class="footer">
      <p>Powered by Your App | <a href="#">Unsubscribe</a></p>
    </div>
  </div>
</body>
</html>
  `;
 
  try {
    const { data, error } = await resend.emails.send({
      from: "digest@yourdomain.com",
      to: options.to,
      subject: options.subject,
      html,
    });
 
    if (error) {
      throw error;
    }
 
    return data;
  } catch (error) {
    console.error("Email sending error:", error);
    throw error;
  }
}

4. GitHub Action for Daily Digest

# .github/workflows/daily-digest.yml
name: Daily Dev Digest
 
on:
  schedule:
    - cron: '0 9 * * *'  # 9 AM UTC daily
  workflow_dispatch:  # Allow manual trigger
 
jobs:
  generate-digest:
    runs-on: ubuntu-latest
 
    steps:
      - name: Checkout code
        uses: actions/checkout@v3
 
      - name: Setup Node.js
        uses: actions/setup-node@v3
        with:
          node-version: '18'
          cache: 'npm'
 
      - name: Install dependencies
        run: npm ci
 
      - name: Generate and send digest
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
          RESEND_API_KEY: ${{ secrets.RESEND_API_KEY }}
          RECIPIENT_EMAIL: ${{ secrets.DIGEST_EMAIL }}
        run: node scripts/generate-digest.js
 
      - name: Notify Slack on failure
        if: failure()
        uses: slackapi/slack-github-action@v1
        with:
          payload: |
            {
              "text": "Daily digest generation failed! Check workflow logs."
            }
        env:
          SLACK_WEBHOOK_URL: ${{ secrets.SLACK_WEBHOOK }}

5. API Route for Webhook (Next.js)

// app/api/webhook/github/route.ts
import { NextRequest, NextResponse } from "next/server";
import crypto from "crypto";
import { get24hActivity } from "@/lib/github-activity";
import { generateDailyDigest } from "@/lib/summarize";
 
function verifySignature(payload: string, signature: string): boolean {
  const secret = process.env.GITHUB_WEBHOOK_SECRET!;
  const hmac = crypto.createHmac("sha256", secret);
  const digest = "sha256=" + hmac.update(payload).digest("hex");
  return crypto.timingSafeEqual(Buffer.from(signature), Buffer.from(digest));
}
 
export async function POST(request: NextRequest) {
  const payload = await request.text();
  const signature = request.headers.get("x-hub-signature-256") || "";
 
  // Verify webhook signature
  if (!verifySignature(payload, signature)) {
    return NextResponse.json({ error: "Invalid signature" }, { status: 401 });
  }
 
  const body = JSON.parse(payload);
  const event = request.headers.get("x-github-event");
 
  console.log(`Received ${event} event for ${body.repository.full_name}`);
 
  // Handle different event types
  switch (event) {
    case "push":
      // Trigger digest generation
      console.log("Push event received, queuing digest generation");
      break;
 
    case "pull_request":
      console.log("PR event received:", body.action);
      break;
 
    default:
      console.log("Unhandled event type:", event);
  }
 
  return NextResponse.json({ received: true }, { status: 200 });
}

TROUBLESHOOTING COMMON ISSUES

GitHub API Rate Limits

Problem: Hitting 60 requests/hour (unauthenticated)

Solutions:

  1. Use GitHub App authentication (5000/hour)
  2. Implement Redis caching (cache for 1 hour)
  3. Use GraphQL instead of REST (fewer requests)
  4. Paginate efficiently (don’t fetch all data)

LLM Response Quality

Problem: Summaries are generic/unhelpful

Solutions:

  1. Improve prompt with examples (few-shot learning)
  2. Provide more context (repo description, recent trends)
  3. Use structured output (JSON mode)
  4. Fine-tune prompts based on user feedback

Email Deliverability

Problem: Emails going to spam

Solutions:

  1. Set up SPF, DKIM, DMARC records
  2. Use professional “from” address (not noreply@)
  3. Warm up email domain gradually
  4. Allow users to whitelist your domain
  5. Use Resend’s shared IP pool (better reputation)

Webhook Reliability

Problem: Missing events, duplicates

Solutions:

  1. Implement idempotency (track processed webhook IDs)
  2. Return 200 status quickly (process async)
  3. Retry logic with exponential backoff
  4. Log all webhooks for debugging
  5. Monitor webhook delivery in GitHub settings

SUCCESS STORIES TO EMULATE

1. GitHub Readme Stats (anuraghazra)

  • Result: 150k+ GitHub stars
  • Why successful: Solved real problem (showcase stats), super easy to use (just add URL to README)
  • Lesson: Make it ridiculously simple to get value

2. Flowdrafter (Product Hunt #1)

  • Result: Most upvoted product of the day
  • Why successful: Built with AI in hours, solved specific pain point, launched with story

  • Result: 500k+ users, acquired
  • Why successful: Content aggregation + community, Chrome extension (easy access)
  • Lesson: Distribution matters (meet users where they are)

NEXT STEPS (Start Now)

  1. Choose your product (DevWrapped or Multi-Repo Digest)
  2. Set up GitHub repo (public for build-in-public)
  3. Create project in Vercel (connect repo)
  4. Get API keys (GitHub App, Claude, Resend)
  5. Day 1 starts tomorrow - follow the sprint plan
  6. Tweet progress daily (#BuildInPublic)
  7. Launch on Day 6 with full force

Remember:

  • Ship fast, iterate faster
  • Talk to users constantly
  • Don’t overthink, just build
  • Viral ≠ perfect, viral = shareable + timely

Good luck building! 🚀
