SF Explorer is built on a generic ERP service abstraction that decouples business logic from Salesforce-specific implementation, enabling extensibility to other platforms (SAP, Dynamics, Marketing Cloud) without rewriting the UI.
┌─────────────────────────────────────────────────────┐
│ Generic Framework Layer │
│ (Business logic, UI components, caching, routing) │
├─────────────────────────────────────────────────────┤
│ ERPService Interface │

└─────────────────────────────────────────────────────┘
Key Benefits:
- 🔄 Testability: Mock the
ERPServiceinterface for unit tests without Salesforce - 🚀 Extensibility: Add SAP/Dynamics support by implementing the same interface
- 🧩 Separation of concerns: UI depends on interface, not concrete implementations
- 🔮 Future-proof: Salesforce API changes stay contained in one place
The ERPService interface provides a universal contract:

Responsibilities:
- Data fetching from Salesforce APIs (REST, SOAP, Tooling, Metadata)
- Business logic and validation
- SOQL query construction and execution
- Metadata management and caching
- State management
- Data transformation
Pattern:
// Example: Salesforce/model/Security/Profile/index.tsx
export default class Profile extends SObject {
// Type-safe field declarations
declare Name: string
declare Description: string
declare UserLicense: string
// Business logic: fetch and normalize metadata
async loadMetadata(): Promise<void> {
const metadata = await this.session.metadataRead('Profile', this.Name)
this.Metadata = normalizeProfileMetadata(metadata)
}
// Data fetching: query related permission sets
async getPermissionSets(): Promise<PermissionSet[]> {
return this.session.soql<PermissionSet>(
`SELECT Id, Name FROM PermissionSet WHERE ProfileId = '${this.Id}'`
).then(r => r.records)
}
// Initialization lifecycle
async init(options?: any): Promise<SObject> {
await super.init(options)
await this.loadMetadata()
return this
}
// View binding: render UI component
Component({ item, options }: ComponentProps): JSX.Element {
return <DefaultView item={item} options={options} />
}
}Key Features:
- Extends
SObjectbase class from Framework (generic ERP abstraction) - TypeScript type definitions for fields (strict type safety)
- Metadata normalization (handles inconsistent XML structures)
- SOQL query builders with type parameters
- Async initialization patterns (lifecycle hooks)
- Dependency injection via Model Provider system (no circular imports)
Responsibilities:
- React component rendering
- User interface state management (useState, useEffect)
- User interactions and event handling
- Data visualization (tables, charts, graphs)
- Layout and styling (SLDS components)
Pattern:
// Example: Salesforce/view/Security/Profile/DefaultView.tsx
import type Profile from "Salesforce/model/Security/Profile"
import type PermissionSet from "Salesforce/model/Security/PermissionSet"
import WithLoading from "Framework/utils/withLoading"
function ProfileViewComponent({ item }: { item: Profile }) {
// UI state
const [activeTab, setActiveTab] = useState('permissions')
const [permissionSets, setPermissionSets] = useState<PermissionSet[]>([])
// Fetch related data
useEffect(() => {
item.getPermissionSets().then(setPermissionSets)
}, [item.Id])
// Event handlers
const handleTabChange = (tab: string) => {
setActiveTab(tab)
}
// Render UI
return (
<SLDSAccordion title={item.Name}>
<Tabs value={activeTab} onChange={handleTabChange}>
<Tab label="Permissions">
{/* Permission matrix */}
</Tab>
<Tab label="Related">
{permissionSets.length} Permission Sets
</Tab>
</Tabs>
</SLDSAccordion>
)
}
// Export with loading HOC (handles async init)
export const DefaultView = WithLoading(ProfileViewComponent)Key Features:
- Type-safe props with model types (imports model as
typeonly) WithLoadingHOC for async data handling (manages loading/error states)- SLDS (Salesforce Lightning Design System) components for consistency
- Material React Table for advanced data grids (sorting, filtering, pagination)
- Monaco Editor for syntax-highlighted code editing (Apex, SOQL, JSON)
- No business logic in views (all logic in model layer)
To avoid circular imports between models, views, and services, we use a Model Provider registry:
// Framework/services/ModelProvider.ts
const modelProviders = new Map<string, () => Promise<typeof SObject>>()
export function registerModelProvider(
name: string,
loader: () => Promise<typeof SObject>
) {
modelProviders.set(name, loader)
}
export async function getModel(name: string) {
const provider = modelProviders.get(name)
if (!provider) return undefined
return await provider() // Lazy-load model on demand
}Usage in Agentforce:
// Agentforce/services/AgentforceModelProvider.ts
registerModelProvider('GenAiPlannerDefinition', async () => {
const { default: GenAiPlannerDefinition } = await import(
'Agentforce/model/GenAiPlannerDefinition'
)
return GenAiPlannerDefinition
})Usage in SalesforceService:
// SalesforceService delegates to Model Providers for extensibility
async getModel(name: string) {
// Try core Salesforce models first
const coreModel = getModel(name)
if (coreModel) return coreModel
// Try Model Providers for extended models (Agentforce, DataCloud)
return await getModelFromProviders(name)
}Result: Zero circular dependencies across 295 files (verified).
// In model file (Salesforce/model/Security/Profile/index.tsx)
import { DefaultView } from "Salesforce/view/Security/Profile/DefaultView"// In view file (Salesforce/view/Security/Profile/DefaultView.tsx)
import type Profile from "Salesforce/model/Security/Profile"// Always use absolute paths
import type User from "Salesforce/model/Security/User"
import type PermissionSet from "Salesforce/model/Security/PermissionSet"Rules:
- ✅ Always use absolute paths starting with
Salesforce/ - ✅ Import types from model layer using
typekeyword - ❌ Never use relative paths (
./,../) - ❌ No circular dependencies between model and view
Verified: See Circular Dependency Analysis - Zero circular dependencies confirmed across 295 files.
SF Explorer implements a smart caching layer that survives component unmounts and page reloads:
// Framework/connector/sessionCache.ts
export class SessionCache {
private memoryCache = new Map<string, any>()
async getOrFetch<T>(
key: string,
fetcher: () => Promise<T>,
options?: {
persist?: boolean // Store in IndexedDB
persistExpiryDays?: number // TTL for IndexedDB cache
serialize?: (data: T) => unknown
deserialize?: (data: unknown) => T
}
): Promise<T> {
// 1. Check in-memory cache (fast)
const cached = this.memoryCache.get(key)
if (cached) return cached
// 2. Check IndexedDB if persist=true (survives reload)
if (options?.persist) {
const persisted = await this.getFromIndexedDB(key)
if (persisted && !this.isExpired(persisted)) {
const deserialized = options.deserialize
? options.deserialize(persisted.data)
: persisted.data
this.memoryCache.set(key, deserialized)
return deserialized
}
}
// 3. Fetch from API and cache both tiers
const fresh = await fetcher()
this.memoryCache.set(key, fresh)
if (options?.persist) {
const serialized = options.serialize ? options.serialize(fresh) : fresh
await this.saveToIndexedDB(key, serialized, options.persistExpiryDays)
}
return fresh
}
}Usage in SalesforceService:
// Fetch bots with persistent caching (survives page reload)
const bots = await service.cacheGetOrFetch(
'AGENTFORCE_BOTS',
() => service.search<BotDefinition>('SELECT Id, Name FROM BotDefinition'),
{
persist: true,
persistExpiryDays: 1,
serialize: (bots) => bots.map(b => b.toSnapshot()),
deserialize: (snapshots) => snapshots.map(BotDefinition.fromSnapshot)
}
)Benefits:
- 🚀 80-90% reduction in Salesforce API calls (critical for orgs with API limits)
- ⚡ Sub-second load times for cached data (instant UI rendering)
- 💾 Survives page reloads (IndexedDB persists across sessions)
- 🔄 Smart invalidation (by key, prefix, or TTL expiry)
- 🧪 Testable (mock the cache for unit tests)

Create Model Class:
Salesforce/model/CategoryName/ModelName/index.tsxexport default class ModelName extends SObject { // Define fields declare fieldName: string // Implement data fetching async loadMetadata(): Promise<void> { } // Render view Component({ item, options }): JSX.Element { return <DefaultView item={item} options={options} /> } }
-
Create View Component:
Salesforce/view/CategoryName/ModelName/DefaultView.tsximport type ModelName from "Salesforce/model/CategoryName/ModelName" import WithLoading from "Framework/utils/withLoading" function DefaultViewComponent({ item }: { item: ModelName }) { return <div>{/* Your UI */}</div> } export const DefaultView = WithLoading(DefaultViewComponent)
-
Register in EntityDefinition: Add metadata in
Framework/model/EntityDefinition/
- No
anytypes: Use proper TypeScript types (enforced by tsconfig strict mode) - SOQL Type Safety: Always provide type parameters for autocomplete + compile-time safety
// ❌ DON'T: Loses field types const results = await session.soql('SELECT Id, Name FROM Profile') // ✅ DO: Type-safe with autocomplete interface ProfileRecord { Id: string Name: string UserLicenseId: string } const results = await session.soql<ProfileRecord>( 'SELECT Id, Name, UserLicenseId FROM Profile' ) results.records.forEach(profile => { console.log(profile.Name.toUpperCase()) // ✅ TypeScript knows Name is string })
- Metadata Normalization: Use
metadataNormalizerto handle inconsistent XML structuresimport { createNormalizer, arrayField, booleanField } from 'Framework/utils/metadataNormalizer' // Salesforce returns arrays OR single objects - normalizer guarantees arrays export const normalizeProfileMetadata = createNormalizer({ fieldPermissions: arrayField(), // Always returns array classAccesses: arrayField(), userPermissions: booleanField(), // Converts string "true" → boolean }) const profile = await service.metadataRead('Profile', 'Admin') const normalized = normalizeProfileMetadata(profile) // Now: normalized.fieldPermissions is always FieldPermission[]

Since launching as a Chrome extension, SF Explorer has:
- 20,000+ active users across Chrome and Edge browsers
- 4.8★ average rating on Chrome Web Store
- Zero reported security issues (OAuth 2.0, no credential storage)
- 80-90% reduction in Salesforce API calls (two-tier caching)
- Sub-second load times for most metadata types (in-memory cache)
- 100% uptime (client-side architecture, no backend servers)
Why this architecture matters for enterprise applications:
-
Generic ERP Abstraction:
ERPServiceinterface makes SF Explorer extensible to other platforms (SAP, Dynamics) without rewriting the UI -
Strict Separation of Concerns: Model-View pattern eliminates circular dependencies and makes testing trivial
-
Type Safety is Non-Negotiable: TypeScript strict mode catches bugs at compile time, not in production
-
Cache Aggressively, Invalidate Carefully: Two-tier caching dramatically improves UX while respecting API limits
-
Dependency Injection > Direct Imports: Model Provider system keeps code decoupled and testable
-
Normalize Early: Metadata transformers hide Salesforce's inconsistent XML structures behind clean TypeScript interfaces
-
Design System Consistency: SLDS + Material UI gives users a familiar, accessible experience
