Learning objectives

  • Master advanced Webpack configurations to optimize enterprise performance
  • Develop code splitting and lazy loading strategies in professional certifying projects
  • Design custom build pipelines integrating plugins and loaders for expert skills
  • Implement caching and tree shaking techniques to reduce bundle sizes
  • Optimize Webpack deployments for scalable applications in professional training
  • Integrate Webpack into DevOps workflows for increased team productivity

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.

  • Organizations that don't train their talents on key topics see their competitiveness drop.

  • Every quarter without training is a gap widening with competitors who invest.

  • The cost of inaction quickly exceeds that of well-targeted training.

Program

Module 1Webpack Configuration: Advanced Architectures and Initial Optimization (Essential Plugins, Production Modes)

Discover advanced Webpack configurations for complex projects, by installing and setting up multiple entry points, optimized output, and custom resolve rules, through practical exercises on a real frontend project. Integrate loaders for Babel and PostCSS, test live the impacts on build time, produce a first performant bundle with a detailed stats report, and apply to web geomatics use cases.

Module 2Webpack Code Splitting: Dynamic Imports and Intelligent Chunks (Analytical Tools, Runtime Performance)

Dive into Webpack code splitting to accelerate application loading. Configure magic comments and SplitChunksPlugin on concrete examples, simulate lazy loading with React Router, analyze bundles using webpack-bundle-analyzer, optimize for mobile via preloading, generate shared chunks for common libraries, apply to interactive GIS dashboards, and measure loading time gains in seconds.

Module 3Webpack Plugins and Loaders: Extreme Customization (Tree Shaking, Advanced Minification, Third-Party Integrations)

Explore the Webpack plugins ecosystem for expert customization. Implement TerserPlugin for aggressive minification and ES module tree shaking, integrate HtmlWebpackPlugin and DefinePlugin for environments, test on multi-entry projects with hot module replacement, optimize assets via image-webpack-loader, deploy to test servers, analyze security and compatibility, and produce production-ready deliverables in a professional context.

Module 4Webpack Deployment and Monitoring: CI/CD, Caching, and Scaling (webpack-dev-server, Advanced Metrics)

Finalize with production Webpack deployments. Configure webpack-dev-server for proxying and HMR, integrate with GitHub Actions for CI/CD pipelines, enable persistent caching via cache-loader, monitor with speed-measure-webpack-plugin, test scalability on large apps, generate Lighthouse reports for performance audits, apply to certifying enterprise workflows, and conclude with a deliverable capstone project.

Evaluation method

  • Daily technical quizzes on Webpack configurations
  • Practical projects evaluated by expert trainers
  • Final case study with personalized feedback

Learning method

  • Practical exercises on real Webpack projects
  • Live coding sessions in interactive remote format
  • Replay videos and post-training resources
  • Pedagogical support 1 month after training

Methods, materials and delivery

The Training Webpack - Optimizing Bundles for Performant Apps program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training Webpack - Optimizing Bundles for Performant Apps program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Training Webpack - Optimizing Bundles for Performant Apps program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Learni programs are available inter-company and intra-company, onsite or remote. Enrollments are possible up to 48 business hours before the program starts. Our programs are eligible for corporate funding paths. Contact us to discuss your training project and funding options.

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.

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.
