Why this program matters

  • Companies that ignore Bun lose development speed.

  • Studies show 30 to 50 percent gains in build performance.

  • Without these skills, JavaScript projects accumulate technical debt and high costs.

  • Developers risk obsolescence against competitors already adopting these tools.

  • Act now to secure your professional advantage.

Bun curriculum: 4 modules over 4 days

Module 1 : Theme: Discovery and installation of Bun (CLI tools, configuration, first scripts)

Participants explore Bun in depth, install the runtime and examine its integrated tools. They perform practical configuration exercises, compare performance with Node.js and create basic scripts. Real-world business cases illustrate speed gains. Deliverables include a functional Bun environment and a simple first project.

Module 2 : Theme: Advanced bundling and execution with Bun (TypeScript, modules, optimizations)

This day focuses on Bun's integrated bundler for complex TypeScript projects. Learners configure optimized builds, manage dependencies and test real-world scenarios. Practical exercises include migrating existing modules. Business cases demonstrate reduced build times. Deliverables are production-ready bundles.

Module 3 : Theme: Bun and Next.js integration (server, API, professional deployment)

Focus on integrating Bun with Next.js for modern web applications. Participants develop high-performance APIs, configure the server and perform integration tests. Practical work includes deployment and optimization exercises. Concrete cases show latency improvements. Deliverables include a functional Next.js application running on Bun.

Module 4 : Theme: Bun testing, security and certification (tools, audits, final projects)

The final day covers Bun's native testing, dependency security and audits. Learners finalize a professional project, present their deliverables and complete a practical assessment. Business cases highlight avoided risks. Deliverables include a comprehensive report and an internal skills certification.

Our method

How Learni guarantees the quality of your Bun training

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.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

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.
Step 3

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.
Step 4

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.
