Program
Bun curriculum: 4 modules over 4 days
Module 1 : Theme: Bun Installation and Benchmarking (CLI, Performance, Migration from Node)
Participants discover Bun installation and perform comparative benchmarks with Node.js on concrete use cases. They explore the CLI for dependency management, native TypeScript compatibility and migration scripts. Practical exercises allow evaluation of speed gains on existing Next.js projects and production of a detailed performance report.
Module 2 : Theme: Advanced Bundling and Execution with Bun (Runtime, Plugins, Next.js Integration)
This day focuses on Bun's integrated bundler and its plugins to optimize builds. Learners configure fast development environments, integrate Bun into Next.js applications and manage complex dependencies. Practical workshops include creating lightweight bundles and testing performance under real enterprise conditions.
Module 3 : Theme: Server APIs and Databases with Bun (HTTP, SQL, Advanced Security)
Experts learn to build high-performance HTTP servers with Bun and connect SQL databases. They implement advanced security measures, manage sessions and optimize queries. Professional use cases enable development of RESTful APIs and measurement of reduced latencies compared to traditional solutions.
Module 4 : Theme: Bun Deployment and Monitoring (CI/CD, Scaling, Observability)
The final day covers production deployment with Bun, integration into CI/CD pipelines and implementation of monitoring tools. Participants deploy Next.js applications on cloud infrastructures, configure alerts and optimize horizontal scaling. A final project delivers a complete architecture and a measurable optimization plan.
