Why this program matters

Without Zod mastery, 75% of TypeScript applications crash on invalid data, causing 30 000€ in annual losses from debugging and fixes.
Teams lose 50% of development time to manual, error-prone validation, leaving SQL injections and XSS vulnerabilities widespread.
By 2026, 82% of backend and frontend job postings require Zod, making profiles obsolete and risking unemployment or forced retraining.
Competitors deploy secure APIs 3x faster, widening the competitiveness gap with sales leaking away.
Each invalid data incident costs 500€ on average, multiplied across e-commerce and SaaS traffic volumes.
Do not doom projects to avoidable vulnerabilities—build your skills with certified training now.

Program

Module 1Zod Fundamentals: Installation and First Schemas (npm, yarn, primitive examples)

Quick installation of Zod in a TypeScript project using npm or yarn, creating primitive schemas for strings, numbers, booleans, and dates, testing validation on user input data from forms, practical exercises with parse and safeParse for detailed errors, real enterprise cases for login input validation, generating readable failure reports, immediate instructor code review to build solid skills from day one.

Module 2Complex Zod Schemas: Objects, Arrays, Unions (nested structures and methods)

Defining nested object schemas with optional fields and discriminated unions, handling arrays, tuples, and maps with recursive validations, exercises integrating real JSON API data, refactoring existing code with robust Zod, practical enterprise cases for HTTP request payloads, using z.object and z.array native tools, automatic TypeScript type generation with infer, consolidating professional structured validation expertise.

Module 3Zod Transformations: Preprocess and Refinements (superRefine and Custom Effects)

Applying .transform for normalizing dates and custom formats, implementing .refine and .superRefine for complex business rules, exercises validating secure emails and passwords, integrating asynchronous effects with promises and databases, real enterprise cases for sanitizing user-generated data, method chaining for natural workflow, producing reusable validators for internal libraries, advanced mastery of enriched contextual errors.

Module 4Zod Integration with Frameworks: Node.js, React, Express (middlewares and hooks)

Configuring Zod middleware for Express route validation in REST and GraphQL APIs, integrating React hooks like useZodForm for dynamic forms, exercises on red thread projects for complete secure APIs, real-time runtime error debugging, enterprise cases migrating from Yup or Joi to modern Zod, performance optimization with lazy schemas, unit tests with Jest Zod matchers, deployment of reusable patterns for multidisciplinary teams, immediate value from certified skills.

Module 5Advanced Zod for Production: Optimization and Deployment (CI/CD, Error Monitoring)

Optimizing production schemas with bundling and tree-shaking in Vite or Webpack, integrating CI/CD with GitHub Actions for automated validation pipelines, monitoring errors with Sentry for Zod issues, exercises finalizing the red thread project with a validated API deployed on Vercel, pair programming code review for best practices, real enterprise cases scaling to 1M requests per day, generated schema documentation with OpenAPI, skills assessment and certification, outlook on future Zod evolutions.

Skills assessment methods

Assessment of skills acquired during the Training Zod - Professional TypeScript Schema Validation 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

Registration is possible up to 48 business hours before the start of training. All our programs are built for corporate L&D budgets and delivered onsite or remotely.

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.
