  • "Ask a senior developer anything" Twitter Space: Questions and answers
    The best resource I know of is Javascript.com for learning Javascript for the first time. It's made by Pluralsight which is a site that contains courses. - Source: dev.to / about 4 years ago

  • Connect Your Bedrock AgentCore Agent to Slack โ€” Without Writing the Slack Part
    Feature-wise, I feel Welt and welt-io both cover what they need to now. So the next step is growing the adapter lineup, and the current front-runner is Mastra (Strands' TypeScript SDK is also a candidate). - Source: dev.to / 20 days ago
  • Asqav now ships on npm. TypeScript agent governance is live
    The interesting frameworks for agents in TypeScript right now are Vercel AI SDK, LangChain.js, and Mastra. Each one gives you a tool-calling loop where the model picks an action, you execute it, and the result feeds back. None of them give you a tamper-evident record of what the agent actually did. - Source: dev.to / 3 months ago
  • Turning Weekly GitHub Activity Into Blog Posts on Notion + DEV.to
    I got tired of that blank moment. So I built DevNotion โ€” a 3-agent pipeline powered by Mastra that harvests my entire week of GitHub activity, narrates it into a first-person blog post using Gemini, and publishes it to Notion (as a planner-style page with structured tables) and DEV.to (as a draft article). Every Sunday, automatically, via GitHub Actions. - Source: dev.to / 4 months ago

  • My Mastra Agent Found a Production Bug in Five Minutes
    I stood up a Mastra workflow via Telegram, pointed it at my three Cloudflare Workers sites, and ran it. Within five minutes it flagged scriptThrewException errors on all three sites. Bots were hitting my media proxy endpoint, the Worker was crashing on every request, and my uptime monitor had been saying everything was fine for days. - Source: dev.to / 4 months ago
