Don't let this gap widen
Without Deno mastery, teams waste 50% of their time managing vulnerable dependencies the way they do with Node.js, exposing the company to 80% of npm breaches in 2024.
Unsecured scripts trigger incidents that cost an average of 15 000€ per breach.
In 2026, 65% of DevOps job postings require Deno, sidelining outdated profiles and blocking promotions.
Every quarter without Deno skills widens a fatal competitive gap against agile rivals.
Quick installation of Deno on various environments, creation of your first executable TypeScript script without complex configuration, exploration of the Deno CLI to import secure URL modules, practical exercises on enterprise automated tasks such as JSON file management, integrated unit tests with Deno test, production of a ready-to-use production script deliverable.
Deep dive into Deno's module system without package.json or node_modules, importing third-party libraries via URL for enhanced security, development of advanced scripts for IT automation such as secure web scraping or CSV data processing, exercises on configuring granular permissions, debugging with the Deno inspector, implementation of a red thread project script to analyze enterprise logs.
Building a performant HTTP server with the minimalist Oak framework, implementing RESTful APIs connected to databases like Deno KV, handling dynamic routes and secure middleware, practical exercises on real enterprise cases such as real-time dashboards via WebSockets, performance optimization with Deno workers, deployment of a functional and tested API prototype.
Preparation for deployment on Deno Deploy and compatible cloud platforms, configuration of CI/CD with GitHub Actions for automated builds, advanced application security with strict TypeScript types and permission audits, exercises on API scalability in enterprise settings, monitoring with integrated Deno tools, finalization of the red thread project with live deployment and complete team documentation.
