Lesson 3: Apex Integration, Data, APIs, Advanced Patterns, and Testing
Lesson Overview
This lesson develops practical skills in apex integration, data, apis, advanced patterns, and testing for Salesforce Lightning Web Components (DEX602).
Topics Covered
Calling Apex with wire and imperative methods, serialization, parameters, and cacheable operations
SOQL, security, CRUD, FLS, sharing, error contracts, and bulk-aware server logic
Dynamic components concepts, reusable services, mixins, modules, and utility libraries
Third-party libraries, static resources, content security policy, and DOM ownership
Jest unit testing, mocks, DOM assertions, events, asynchronous behavior, and coverage
Integration, performance, and negative testing
Practical Activity
Configure or analyze a scenario involving calling apex with wire and imperative methods, serialization, parameters, and cacheable operations.
Build and validate an exercise covering soql, security, crud, fls, sharing, error contracts, and bulk-aware server logic and dynamic components concepts, reusable services, mixins, modules, and utility libraries.
Use tests, logs, reports, or documentation to verify integration, performance, and negative testing.
Key Takeaways
Explain calling apex with wire and imperative methods, serialization, parameters, and cacheable operations in the context of Salesforce Lightning Web Components (DEX602).
Apply practical methods for soql, security, crud, fls, sharing, error contracts, and bulk-aware server logic and dynamic components concepts, reusable services, mixins, modules, and utility libraries.
Test, document, and troubleshoot integration, performance, and negative testing.
