Program
Module 1Theme: Introduction to Bun and First Steps (installation, configuration, simple scripts)
Participants discover Bun as a modern JavaScript runtime. They install the environment, explore basic commands and run their first scripts. Practical exercises include creating simple files, managing dependencies and comparing with Node. Each learner leaves with an initial functional project ready to evolve.
Module 2Theme: Development with Bun and TypeScript Integration (tools, APIs, tests)
This day deepens the creation of APIs and modules with Bun. Learners configure TypeScript natively, use the built-in APIs and write automated tests. Real-world business cases allow them to manipulate data and structure clean code. They deliver a documented mini-API project.
Module 3Theme: Bundling and Performance with Bun and Next.js (builds, optimization)
Participants master Bun's integrated bundler to generate fast builds. They integrate Next.js, optimize assets and measure speed gains. Practical exercises cover local deployment and performance analysis. The deliverable is an optimized Next.js application using Bun.
Module 4Theme: Professional Deployment and Bun Best Practices (workflows, security)
The final day covers production deployment, environment variable management and security best practices. Learners finalize a complete project, conduct code reviews and present their solutions. They receive guidance to apply these skills directly in their company.

Our method
Training quality, guaranteed at every step
Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
