Nestjs Search

職業

カテゴリ

NoSQL データベース

Organization

• Module: Encapsulate client in SearchModule.
• Abstraction: Create generic SearchService<T> helpers.
• indexDocument(id, body)
• search(query, filters)
• Mapping: Use class-transformer to map Entities to "Search Documents". Keep docs flatter than relational entities.

Testing

• E2E: not mock search engine in critical E2E flows.
• Docker: Spin up elasticsearch:8 container in test harness to verify indexing works.

Anti-Patterns

• No dual writes to DB + ES: Use event-driven or CDC pattern; dual writes risk partial failure inconsistency.
• No Elasticsearch for structured queries: Use DB indexes for filtering; ES for full-text and complex search.
• No ES mocks in E2E search tests: Spin up elasticsearch:8 container to verify indexing behavior accurately.3a:["$","$L42",null,{"content":"$43","frontMatter":{"name":"nestjs-search","description":"Integrate Elasticsearch and implement search index Sync patterns in NestJS.
