Salesforce Component Quality Standards

Apply these checks to every LWC, Aura component, and Visualforce page you write or review.

Section 1 — LWC Quality Standards

Choose the right data access pattern before writing JavaScript controller code:

Use case	Pattern	Why
Read a single record reactively (follows navigation)	`@wire(getRecord, { recordId, fields })`	Lightning Data Service — cached, reactive
Standard CRUD form for a single object	`<lightning-record-form>` or `<lightning-record-edit-form>`	Built-in FLS, CRUD, and accessibility
Complex server query or filtered list	`@wire(apexMethodName, { param })` on a `cacheable=true` method	Allows caching; wire re-fires on param change
User-triggered action, DML, or non-cacheable server call	Imperative `apexMethodName(params).then(...).catch(...)`	Required for DML — wired methods cannot be `@AuraEnabled` without `cacheable=true`
Cross-component communication (no shared parent)	Lightning Message Service (LMS)	Decoupled, works across DOM boundaries
Multi-object graph relationships	GraphQL `@wire(gql, { query, variables })`	Single round-trip for complex related data
