CustomApplication (Lightning App) Metadata Specification

Overview

Custom applications (Lightning Apps) that group tabs and functionality to provide a focused user experience for specific business processes. Always configured for Lightning Experience.

Purpose

• Organize related functionality into focused applications
• Group tabs and components for specific user roles
• Provide tailored user experiences
• Control access to specific features and data
• Use Standard navigation for general business applications or Console navigation for specialized service/support workflows requiring multi-tab workspaces
• Create professional, branded application identity with custom colors and branding
• Override standard actions with custom Lightning pages for enhanced user experience
• Enable profile-specific experiences through profile action overrides

Application Configuration

Navigation Type Selection (CRITICAL)

Decision Criteria for navType:

Choose "Standard" (DEFAULT) for:

• General business applications and most workflows
• Single-record focus or linear navigation patterns
• Standard tab-based navigation is sufficient

Choose "Console" ONLY when workflow requires:

• Managing multiple related records simultaneously in split-view
• Multi-tab workspace for handling complex, interconnected data
• Contextual information from multiple sources visible at once
• Examples: customer service operations, support desks, call centers

When in doubt: Default to "Standard" for most general business use cases

Navigation Settings

• isNavAutoTempTabsDisabled: Controls automatic temporary tab creation
• isNavPersonalizationDisabled: Controls user personalization features
• isNavTabPersistenceDisabled: Controls tab persistence across sessions

Tab Management

• tabs: Array of tab names to include in the application

Branding (HIGHLY RECOMMENDED - DO NOT SKIP)

IMPORTANT: Provide branding configuration to create a professional, visually distinct application identity.

• brand.headerColor: Header bar color in hex format (e.g., "#0070D2") - RECOMMENDED
• brand.shouldOverrideOrgTheme: Override organization theme (true/false) - Default: false
• brand.footerColor: Footer color in hex format

Action Overrides (CRITICAL - DO NOT SKIP)

IMPORTANT: Action overrides MUST be created for every custom object tab that has a record page generated by flexipage expert.

• actionOverrides.actionName: Action to override ("View" or "Tab")
• actionOverrides.content: Page/component name (FlexiPage, Visualforce, Lightning component)
  • For "View" action: Reference record pages generated by flexipage expert

• actionOverrides.formFactor: Device type ("Large" or "Small")
• actionOverrides.type: Override type ("Default", "Visualforce", "Flexipage", "LightningComponent", "Scontrol")
  • Recommended: Use "Flexipage" for Lightning record/home pages generated by flexipage expert
• actionOverrides.pageOrSobjectType: Object API name the override applies to
• actionOverrides.comment: Optional description (max 1000 characters)
  • Auto-generated comment: "Action override created by Lightning App Builder during activation."
• actionOverrides.skipRecordTypeSelect: Skip record type selection (default: false)

Profile Action Overrides

• profileActionOverrides.actionName: Action to override ("View" or "Tab")
• profileActionOverrides.content: Page/component name
  • For "View" action: Reference profile-specific record pages generated by flexipage expert
  • For "Tab" action: Reference profile-specific home pages generated by flexipage expert

Best Practices

• Always use Lightning UI: Set uiType to "Lightning" for modern apps

• Use clear, descriptive application names
• Group related functionality logically
• Consider different user roles and needs
• Test across different device types
• Ensure proper permissions and access control
• Provide meaningful descriptions for users
• Follow consistent naming conventions
• Always configure branding: Set headerColor to create professional application identity
• Use accessible brand colors: Ensure hex colors have sufficient contrast (WCAG AA compliant)
• Configure utility bars: Add useful quick-access tools for users
• Leverage action overrides: Customize page layouts for specific objects using FlexiPages from flexipage expert
• Use profile overrides: Provide role-specific experiences by referencing different flexipage expert generated pages per profile
