Предыдущая статья: Интеграция внешнего файлового сервера https://min.io в фулстек приложение на NestJS и Angular
На каждом фронтенд запросе к бэкенду запрашивается информация по профилю пользователя из базы данных, это создает дополнительную нагрузку на базу данных и увеличивает время ответа бэкенда, для ускорения подобных запросов можно кэшировать ответ базы данных.
В этом посте я подключу Redis к проекту и настрою кэширование данных через @nestjs-mod/cache-manager.
Проект можно запускать в Docker Compose и Kubernetes.
1. Устанавливаем дополнительные библиотеки
Устанавливаем JS-клиент и NestJS-модуль для работы с cache-manager и Redis.
Команды
npm install --save redis cache-manager-redis-yet cache-manager @nestjs-mod/cache-manager Вывод консоли
$ npm install --save redis cache-manager-redis-yet cache-manager @nestjs-mod/cache-manager npm warn deprecated cache-manager-redis-yet@5.1.5: With cache-manager v6 we now are using Keyv added 17 packages, removed 2 packages, and audited 2934 packages in 19s 360 packages are looking for funding run `npm fund` for details 41 vulnerabilities (19 low, 7 moderate, 15 high) To address issues that do not require attention, run: npm audit fix To address all issues possible (including breaking changes), run: npm audit fix --force Some issues need review, and may require choosing a different dependency. Run `npm audit` for details. 2. Подключаем новые модули в бэкенд
Обновляем файл apps/server/src/main.ts
import { DOCKER_COMPOSE_FILE, DockerCompose, DockerComposeAuthorizer, DockerComposeMinio, DockerComposePostgreSQL, } from '@nestjs-mod/docker-compose'; // ... import { MinioModule } from '@nestjs-mod/minio'; // ... import { ExecutionContext } from '@nestjs/common'; // ... bootstrapNestApplication({ modules: { // ... core: [ CacheManagerModule.forRoot({ staticConfiguration: { type: isInfrastructureMode() ? 'memory' : 'redis', }, }), ], infrastructure: [ DockerComposeMinio.forRoot({ staticConfiguration: { image: 'bitnami/minio:2024.11.7' }, }), ]} ); 3. Запускаем генерацию дополнительного кода по инфраструктуре
Команды
npm run docs:infrastructure После запуска в docker-compose-файле появится новый сервис server-redis и в переменной окружения появится новая переменная окружения SERVER_REDIS_URL, которую нужно заполнить.
Обновленный файл apps/server/docker-compose-prod.yml
server-redis: image: 'bitnami/redis:7.4.1' container_name: 'server-redis' volumes: - 'server-redis-volume:/bitnami/redis/data' ports: - '6379:6379' networks: - 'server-network' environment: REDIS_DISABLE_COMMANDS: '${SERVER_REDIS_REDIS_DISABLE_COMMANDS}' REDIS_IO_THREADS: '${SERVER_REDIS_REDIS_IO_THREADS}' REDIS_IO_THREADS_DO_READS: '${SERVER_REDIS_REDIS_IO_THREADS_DO_READS}' healthcheck: test: - 'CMD-SHELL' - 'redis-cli ping | grep PONG' interval: '5s' timeout: '5s' retries: 5 tty: true restart: 'always' Обновляем файл .env
# ... SERVER_REDIS_URL=redis://:CHmeOQrZWUHwgahrfzsrzuREOxgAENsC@localhost:6379 Повторно запускаем генерацию дополнительного кода по инфраструктуре, для генерации дополнительных переменных окружения.
Команды

Запускаем инфраструктуру с приложениями в режиме разработки и проверяем через E2E-тесты
Команды
npm run pm2-full:dev:start npm run pm2-full:dev:test:e2e 5. Добавляем сервис для кэширования в WebhookModule-модуль
Создаем файл libs\feature\webhook\src\lib\services\webhook-cache.service.ts
import { CacheManagerService } from '@nestjs-mod/cache-manager'; import { InjectPrismaClient } from '@nestjs-mod/prisma'; import { Injectable } from '@nestjs/common'; import { PrismaClient, WebhookUser } from '@prisma/webhook-client'; import { WEBHOOK_FEATURE } from '../webhook.constants'; import { WebhookConfiguration } from '../webhook.configuration'; @Injectable() export class WebhookCacheService { constructor( @InjectPrismaClient(WEBHOOK_FEATURE) private readonly prismaClient: PrismaClient, private readonly webhookConfiguration: WebhookConfiguration, private readonly cacheManagerService: CacheManagerService ) {} async clearCacheByExternalUserId(externalUserId: string) { const webhookUsers = await this.prismaClient.webhookUser.findMany({ where: { externalUserId }, }); for (const webhookUser of webhookUsers) { await this.cacheManagerService.del(this.getUserCacheKey(webhookUser)); } } async getCachedUserByExternalUserId(externalUserId: string, externalTenantId?: string) { const cached = await this.cacheManagerService.get<WebhookUser | null>( this.getUserCacheKey({ externalUserId, externalTenantId, }) ); if (cached) { return cached; } const user = await this.prismaClient.webhookUser.findFirst({ where: { externalUserId, ...(externalTenantId ? { externalTenantId } : {}), }, }); if (user) { await this.cacheManagerService.set(this.getUserCacheKey({ externalTenantId, externalUserId }), user, this.webhookConfiguration.cacheTTL); return user; } return null; } private getUserCacheKey({ externalTenantId, externalUserId }: { externalTenantId: string | undefined; externalUserId: string }): string { return `${externalTenantId}_${externalUserId}`; } } Данные по пользователю кэшируются на 15 секунд, время кэширования устанавливается через конфигурацию модуля.
Обновляем файл libs\feature\webhook\src\lib\webhook.configuration.ts
import { ConfigModel, ConfigModelProperty } from '@nestjs-mod/common'; import { WebhookEvent } from './types/webhook-event-object'; @ConfigModel() export class WebhookConfiguration { @ConfigModelProperty({ description: 'List of available events.', }) events!: WebhookEvent[]; @ConfigModelProperty({ description: 'TTL for cached data.', default: 15_000, }) cacheTTL?: number; } // ... В WebhookGuard заменяем получение данных через орм на получение данных из сервиса кэирования.
Обновляем файл libs\feature\webhook\src\lib\webhook.guard.ts
//... import { WebhookCacheService } from './services/webhook-cache.service'; @Injectable() export class WebhookGuard implements CanActivate { private logger = new Logger(WebhookGuard.name); constructor( //... private readonly webhookCacheService: WebhookCacheService ) {} //... private async tryGetOrCreateCurrentUserWithExternalUserId(req: WebhookRequest, externalTenantId: string | undefined, externalUserId: string) { if (!req.webhookUser) { if (!externalTenantId || !isUUID(externalTenantId)) { throw new WebhookError(WebhookErrorEnum.EXTERNAL_TENANT_ID_NOT_SET); } if (this.webhookEnvironments.autoCreateUser) { req.webhookUser = await this.webhookCacheService.getCachedUserByExternalUserId(externalUserId, externalTenantId); if (!req.webhookUser) { await this.prismaClient.webhookUser.create({ data: { externalTenantId, externalUserId, userRole: 'User' }, }); } } req.webhookUser = await this.webhookCacheService.getCachedUserByExternalUserId(externalUserId, externalTenantId); } } private async tryGetCurrentSuperAdminUserWithExternalUserId(req: WebhookRequest, externalUserId: string) { if (!req.webhookUser && this.webhookEnvironments.superAdminExternalUserId === externalUserId) { req.webhookUser = await this.webhookCacheService.getCachedUserByExternalUserId(externalUserId); } } //... } В контроллере с методами модификации пользователей добавляем вызов инвалидации кэша при изменении и удалении пользователя.
Обновляем файл libs\feature\webhook\src\lib\controllers\webhook-users.controller.ts
//... import { WebhookCacheService } from '../services/webhook-cache.service'; @ApiExtraModels(WebhookError) @ApiBadRequestResponse({ schema: { allOf: refs(WebhookError) }, }) @ApiTags('webhook') @CheckWebhookRole([WebhookRole.Admin]) @Controller('/webhook/users') export class WebhookUsersController { constructor( //... private readonly webhookCacheService: WebhookCacheService ) {} //... @Put(':id') @ApiOkResponse({ type: WebhookUserObject }) async updateOne(@CurrentWebhookExternalTenantId() externalTenantId: string, @CurrentWebhookUser() webhookUser: WebhookUser, @Param('id', new ParseUUIDPipe()) id: string, @Body() args: UpdateWebhookUserArgs) { const result = await this.prismaClient.webhookUser.update({ data: { ...args }, where: { id, ...this.webhookToolsService.externalTenantIdQuery(webhookUser, webhookUser.userRole === 'Admin' ? undefined : externalTenantId), }, }); await this.webhookCacheService.clearCacheByExternalUserId(webhookUser.externalUserId); return result; } @Delete(':id') @ApiOkResponse({ type: StatusResponse }) async deleteOne(@CurrentWebhookExternalTenantId() externalTenantId: string, @CurrentWebhookUser() webhookUser: WebhookUser, @Param('id', new ParseUUIDPipe()) id: string) { await this.prismaClient.webhookUser.delete({ where: { id, ...this.webhookToolsService.externalTenantIdQuery(webhookUser, webhookUser.userRole === 'Admin' ? undefined : externalTenantId), }, }); await this.webhookCacheService.clearCacheByExternalUserId(id); return { message: 'ok' }; } //... } Подключаем сервис кэшировнаия в модуль WebhookModule.
Обновляем файл libs/feature/webhook/src/lib/webhook.module.ts
//... import { CacheManagerModule } from '@nestjs-mod/cache-manager'; import { WebhookCacheService } from './services/webhook-cache.service'; export const { WebhookModule } = createNestModule({ moduleName: WEBHOOK_MODULE, moduleCategory: NestModuleCategory.feature, staticEnvironmentsModel: WebhookEnvironments, staticConfigurationModel: WebhookStaticConfiguration, configurationModel: WebhookConfiguration, imports: [ //... CacheManagerModule.forFeature({ featureModuleName: WEBHOOK_FEATURE, }), ], providers: [ //... WebhookCacheService, ], //... }); 6. Обновляем файлы и добавляем новые для запуска docker-compose и kubernetes
Полностью описывать изменения во всех файлах я не буду, их можно посмотреть по коммиту с изменениями для текущего поста, ниже просто добавлю обновленный docker-compose-full.yml и его файл с переменными окружения.
Обновляем файл .docker/docker-compose-full.yml

В данном посте показан простой способ кэширования и инвалидации кэша, если сущностей и данных для кэширования больше, то нужно продумывать иной способ кэширования и инвалидации, для того чтобы писать меньше кода.

В следующем посте я добавлю получение серверного времени через WebSockets и отображение его в Angular-приложении…
