The entire process happens in the browser for maximum security. + +## Key Components + +### 1. NVS Partition Builder (`src/nvs-partition-builder.ts`) +- **Purpose**: Builds ESP32 NVS binary partitions from key-value pairs +- **Format**: Implements ESP-IDF NVS partition format specification +- **Features**: + - CRC32 checksum calculation for data integrity + - Support for multiple data types (u8, u16, u32, string, blob) + - Page-aligned output (4096-byte pages) + - Namespace support for organizing entries + - Multi-page support for larger datasets + - **Struct packing for ESPHome compatibility** + - Numeric key support (ESPHome preferences API) + +**Key Functions**: +- `buildNVSPartition(entries, size)` - Main builder function +- `buildESPHomeWiFiNVS(ssid, password, hash)` - ESPHome WiFi credentials with correct struct format +- `packStruct(fields)` - Pack multiple values into binary struct (C struct layout) + +### 2. Manifest Extensions (`src/const.ts`) +New TypeScript interfaces added: + +```typescript +interface CustomFormField { + name: string; // Unique field identifier + label: string; // Display label + type: "text" | "password" | "number" | "checkbox"; + required?: boolean; // Validation flag + defaultValue?: string | number | boolean; + placeholder?: string; +} + +interface NVSPartitionConfig { + offset: number; // Flash address for partition + size?: number; // Partition size (default: 12288) + namespace: string; // NVS namespace + + // Option 1: Struct-based storage (ESPHome compatible) + struct?: { + key: number; // Numeric key (hash) + fields: Array<{ + name: string; // Form field name + type: "u8" | "u16" | "u32" | "string"; + maxLength?: number; // For string: fixed buffer size + }>; + }; + + // Option 2: Individual field storage + fields?: Array<{ + name: string; // Form field name to map + key: string; // NVS key name + type: "u8" | "u16" | "u32" | "string"; + }>; +} +``` + +**Important**: ESPHome uses `struct` mode with numeric keys, not `fields` mode. + +### 3. Configuration UI (`src/install-dialog.ts`) +- **New State**: `CONFIGURATION` - Shows configuration form +- **Flow Integration**: Seamlessly integrates with existing install flow +- **Validation**: Required field validation with error messages +- **Form Rendering**: Uses existing Material Design components + +**User Flow**: +1. User clicks "Install" from dashboard +2. If `customFields` defined → Show configuration form +3. User fills in configuration values +4. (Optional) Erase confirmation if `new_install_prompt_erase` is true +5. Confirmation dialog +6. NVS partition built from form values +7. Firmware + NVS flashed together + +### 4. Flash Integration (`src/flash.ts`) +- Modified `flash()` function to accept optional `nvsData` parameter +- NVS partition added to file array at specified offset +- Flashed using same esptool-js process as firmware + +## Security Features +✅ **No server communication**: All processing happens in browser +✅ **No credential exposure**: Data never leaves user's device +✅ **Direct device write**: NVS written via Web Serial API +✅ **No intermediate storage**: Form data cleared after flash +✅ **CodeQL validated**: No security vulnerabilities detected + +## Compatibility + +### Browser Support +- Chrome 89+ +- Edge 89+ +- Opera 76+ +- (Requires Web Serial API support) + +### ESP32 Support +- ESP32 +- ESP32-S2 +- ESP32-S3 +- ESP32-C3 +- ESP32-C6 +- Other ESP32 variants with NVS support + +## Usage Example + +### Manifest Configuration (ESPHome WiFi) +```json +{ + "name": "ESPHome Device", + "version": "1.0.0", + "customFields": [ + { + "name": "wifi_ssid", + "label": "WiFi SSID", + "type": "text", + "required": true + }, + { + "name": "wifi_password", + "label": "WiFi Password", + "type": "password", + "required": true + } + ], + "nvsPartition": { + "offset": 36864, + "namespace": "esphome", + "struct": { + "key": 88491487, + "fields": [ + { "name": "wifi_ssid", "type": "string", "maxLength": 33 }, + { "name": "wifi_password", "type": "string", "maxLength": 65 } + ] + } + }, + "builds": [...] +} +``` + +### Firmware Integration (ESPHome Example) +```cpp +// Firmware reads from NVS using ESPHome preferences API: +#include "esphome/core/preferences.h" + +struct SavedWifiSettings { + char ssid[33]; + char password[65]; +} PACKED; + +uint32_t hash = App.get_config_version_hash(); // or use 88491487 +auto pref = global_preferences->make_preference(hash, true); + +SavedWifiSettings settings; +if (pref.load(&settings)) { + // Use settings.ssid and settings.password + ESP_LOGD(TAG, "Loaded WiFi settings: %s", settings.ssid); +} +``` + +### Alternative: Individual Field Storage +```json +{ + "nvsPartition": { + "offset": 36864, + "namespace": "config", + "fields": [ + { "name": "wifi_ssid", "key": "ssid", "type": "string" }, + { "name": "wifi_password", "key": "password", "type": "string" } + ] + } +} +``` + +This mode stores each field separately (not ESPHome compatible). + +## Testing + +### Unit Tests (test-nvs.html) +- Test 1: Simple NVS partition with basic types +- Test 2: ESPHome WiFi credentials (legacy individual fields) +- Test 3: Multi-field configuration +- Test 4: ESPHome WiFi struct (correct format with numeric key) +- Test 5: Binary struct packing + +### Integration Testing +Requires physical ESP32 device: +1.

NVS Partition Builder Test

+

This page tests the NVS partition builder functionality without requiring hardware.

+ +
+

Test 1: Build Simple NVS Partition

+ +
+
+ +
+

Test 2: Build ESPHome WiFi Partition

+ +
+
+ +
+

Test 3: Build Multi-Field Configuration

+ +
+
+ +
+

Test 4: Build ESPHome WiFi Struct (Correct Format)

+ +
+
+ +
+

Test 5: Pack Binary Struct

+ +
+
+ +
+

Interactive Test: ESPHome WiFi Configuration

+

Try the configuration form with ESPHome WiFi struct format:

+ + Test ESPHome WiFi Form + +

+ This uses the correct ESPHome struct format with numeric key. +

+
+ +
+

Interactive Test: Custom Configuration

+

Try the configuration form with individual field storage:

+ + Test Configuration Form + +

+ Note: You'll need an ESP32 device connected to test the actual flashing. + The form will work without hardware to demonstrate the UI. + Run script/develop to start the dev server, then open http://localhost:5001/test-nvs.html +
