From fecaa59a2a3acb9845a3b1559743ccaa39520ca4 Mon Sep 17 00:00:00 2001 From: Matthew Raymer Date: Wed, 2 Jul 2025 10:09:12 +0000 Subject: [PATCH] Enhance PlatformServiceMixin with utility methods and apply to TopMessage Add $getSettings, $getMergedSettings utilities with built-in error handling. Reduce TopMessage code by 57% while eliminating Vue property conflicts. --- src/components/TopMessage.vue | 111 ++++------------ src/utils/PlatformServiceMixin.ts | 213 +++++++++++++++++++++++++++--- 2 files changed, 217 insertions(+), 107 deletions(-) diff --git a/src/components/TopMessage.vue b/src/components/TopMessage.vue index 51e088e4..3c94f4ee 100644 --- a/src/components/TopMessage.vue +++ b/src/components/TopMessage.vue @@ -18,22 +18,19 @@ import { Component, Vue, Prop } from "vue-facing-decorator"; import { AppString, NotificationIface } from "../constants/app"; import { MASTER_SETTINGS_KEY } from "../db/tables/settings"; import { DEFAULT_ENDORSER_API_SERVER } from "../constants/app"; -import { - PlatformServiceMixin, - IPlatformServiceMixin, -} from "../utils/PlatformServiceMixin"; -import { mapColumnsToValues, parseJsonField } from "../db/databaseUtil"; +import { PlatformServiceMixin } from "../utils/PlatformServiceMixin"; @Component({ mixins: [PlatformServiceMixin], }) export default class TopMessage extends Vue { - // NOTE: This component uses PlatformServiceMixin which provides: - // - this.dbQuery(), this.dbExec(), this.dbGetOneRow() methods - // - this.platformService computed property - // - this.isCapacitor, this.isWeb, this.isElectron computed properties + // Enhanced PlatformServiceMixin provides: + // - this.$dbQuery(), this.$dbExec(), this.$dbGetOneRow() with built-in error handling + // - this.$getSettings(), this.$getMergedSettings() utility methods + // - this.$withTransaction() for safe database transactions + // - this.platformService, this.isCapacitor, this.isWeb, this.isElectron // - this.capabilities computed property - // TypeScript requires (this as any) for mixin methods due to compile-time limitations + // All methods use $ prefix following Vue conventions $notify!: (notification: NotificationIface, timeout?: number) => void; @@ -71,97 +68,37 @@ export default class TopMessage extends Vue { } /** - * Get settings for the active account using the platform service mixin. - * This demonstrates the concise mixin pattern with direct database access. + * Get settings for the active account using enhanced mixin utilities. + * Dramatically simplified using $getMergedSettings utility method. */ private async getActiveAccountSettings() { - // Declare defaultSettings outside try block for proper scope - let defaultSettings; - try { - // Get default settings first - defaultSettings = await this.getDefaultSettings(); - - // If no active DID, return defaults - if (!defaultSettings.activeDid) { - return defaultSettings; - } - - // Get account-specific settings using the mixin (much more concise!) - const result = await (this as any).dbQuery( - "SELECT * FROM settings WHERE accountDid = ?", - [defaultSettings.activeDid], - ); - - if (!result?.values?.length) { - return defaultSettings; - } - - // Map and filter settings - const overrideSettings = mapColumnsToValues( - result.columns, - result.values, - )[0] as any; - - const overrideSettingsFiltered = Object.fromEntries( - Object.entries(overrideSettings).filter(([_, v]) => v !== null), - ); - - // Merge settings - const settings = { ...defaultSettings, ...overrideSettingsFiltered }; - - // Handle searchBoxes parsing - if (settings.searchBoxes) { - settings.searchBoxes = parseJsonField(settings.searchBoxes, []); - } - - return settings; - } catch (error) { - console.error( - `Failed to retrieve account settings for ${defaultSettings?.activeDid}:`, - error, - ); - return ( - defaultSettings || { + // First get the default settings to find activeDid + const defaultSettings = await (this as any).$getSettings( + MASTER_SETTINGS_KEY, + { id: MASTER_SETTINGS_KEY, activeDid: undefined, apiServer: DEFAULT_ENDORSER_API_SERVER, - } + }, ); - } - } - /** - * Get default settings using the platform service mixin - */ - private async getDefaultSettings() { - try { - // Direct database access via mixin - no destructuring needed!
