From 7a1329e1a48a9a0d6a872aa46d2fee98a135b688 Mon Sep 17 00:00:00 2001 From: Matthew Raymer Date: Wed, 11 Jun 2025 08:40:33 +0000 Subject: [PATCH] feat: enhance file save and share with location selection options - Add enhanced writeAndShareFile method with flexible save options - Support save to Downloads folder (Android) and Documents (iOS) - Add framework for file picker location selection - Improve error handling with detailed result objects - Update PlatformService interface for new options - Add writeFile method for basic app storage operations - Update DataExportSection to use enhanced API with location selection - Maintain backward compatibility with existing implementations - Add comprehensive logging for debugging and monitoring This provides users with better control over where files are saved while maintaining the existing share functionality and adding multiple fallback strategies for improved reliability. --- .gitignore | 1 + src/components/DataExportSection.vue | 17 +- src/services/PlatformService.ts | 13 +- .../platforms/CapacitorPlatformService.ts | 358 +++++++++--------- 4 files changed, 213 insertions(+), 176 deletions(-) diff --git a/.gitignore b/.gitignore index 937ac99f..0a444b8b 100644 --- a/.gitignore +++ b/.gitignore @@ -21,6 +21,7 @@ npm-debug.log* yarn-debug.log* yarn-error.log* pnpm-debug.log* +android/app/src/main/res/ # Editor directories and files .idea diff --git a/src/components/DataExportSection.vue b/src/components/DataExportSection.vue index 842b2201..858742d8 100644 --- a/src/components/DataExportSection.vue +++ b/src/components/DataExportSection.vue @@ -162,8 +162,21 @@ export default class DataExportSection extends Vue { downloadAnchor.click(); setTimeout(() => URL.revokeObjectURL(this.downloadUrl), 1000); } else if (this.platformCapabilities.hasFileSystem) { - // Native platform: Write to app directory - await this.platformService.writeAndShareFile(fileName, jsonStr); + // Native platform: Write to app directory with enhanced options + const result = await this.platformService.writeAndShareFile( + fileName, + jsonStr, + { + allowLocationSelection: true, + saveToDownloads: false, + mimeType: "application/json" + } + ); + + // Handle the result + if (!result.saved) { + throw new Error(result.error || "Failed to save file"); + } } else { throw new Error("This platform does not support file downloads."); } diff --git a/src/services/PlatformService.ts b/src/services/PlatformService.ts index 78fc5192..52e22b80 100644 --- a/src/services/PlatformService.ts +++ b/src/services/PlatformService.ts @@ -65,9 +65,18 @@ export interface PlatformService { * Writes content to a file at the specified path and shares it. * @param fileName - The filename of the file to write * @param content - The content to write to the file - * @returns Promise that resolves when the write is complete + * @param options - Optional parameters for file saving behavior + * @returns Promise that resolves to save/share result */ - writeAndShareFile(fileName: string, content: string): Promise; + writeAndShareFile( + fileName: string, + content: string, + options?: { + allowLocationSelection?: boolean; + saveToDownloads?: boolean; + mimeType?: string; + } + ): Promise<{ saved: boolean; uri?: string; shared: boolean; error?: string }>; /** * Deletes a file at the specified path. diff --git a/src/services/platforms/CapacitorPlatformService.ts b/src/services/platforms/CapacitorPlatformService.ts index 26bef6f8..55e2e62b 100644 --- a/src/services/platforms/CapacitorPlatformService.ts +++ b/src/services/platforms/CapacitorPlatformService.ts @@ -41,7 +41,7 @@ interface QueuedOperation { */ export class CapacitorPlatformService implements PlatformService { /** Current camera direction */ - private currentDirection: CameraDirection = "BACK"; + private currentDirection: CameraDirection = "BACK" as CameraDirection; private sqlite: SQLiteConnection; private db: SQLiteDBConnection | null = null; @@ -379,213 +379,169 @@ export class CapacitorPlatformService implements PlatformService { } /** - * Writes content to a file in the app's safe storage and offers sharing. - * - * Platform-specific behavior: - * - Saves to app's Documents directory - * - Offers sharing functionality to move file elsewhere - * - * The method handles: - * 1.
