Caching information in Redis on NestJS
Publication date: 2024-11-20
Each frontend request to the backend requests user profile information from the database, this creates an additional load on the database and increases the backend response time, to speed up such requests, you can cache the database response.
In this post, I will connect Redis to the project and set up data caching via @nestjs-mod/cache-manager.
The project can be run in Docker Compose and Kubernetes.
1. Install additional libraries
Install JS-client and NestJS-module for working with cache-manager and Redis.
Commands
npm install --save redis cache-manager-redis-yet cache-manager @nestjs-mod/cache-manager
$ 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

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. Connecting new modules to the backend
Updating the file 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. We are starting the generation of additional code for the infrastructure
Commands
npm run docs:infrastructure
After running, a new service server-redis will appear in the docker-compose file and a new environment variable SERVER_REDIS_URL will appear in the environment variable, which needs to be filled.
Updated file 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: '${SERVER_REDIS_REDIS_IO_THREADS_DO_READS}'
healthcheck:
test:
- 'CMD-SHELL'
- 'redis-cli ping | grep PONG'
interval: '5s'
timeout: '5s'
retries: 5
tty: true
restart: 'always'
Updating the file .env
# ...
SERVER_REDIS_URL=redis://:CHmeOQrZWUHwgahrfzsrzuREOxgAENsC@localhost:6379
We re-run the generation of additional code for the infrastructure to generate additional environment variables.
Commands
npm run docs:infrastructure
Updated file apps/server/docker-compose-prod.yml
server-redis:
image: 'bitnami/redis:7.4.1'
container_name: 'server-redis'
volumes:
- 'server-redis-volume:/bitnami/redis/data'
ports:
- '6379:6379'
networks:
- 'server-network'
environment:
REDIS_DATABASE: '${SERVER_REDIS_REDIS_DATABASE}'
REDIS_PASSWORD: '${SERVER_REDIS_REDIS_PASSWORD}'
REDIS_DISABLE_COMMANDS: '${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 --no-auth-warning -a $$REDIS_PASSWORD ping | grep PONG'
interval: '5s'
timeout: '5s'
retries: 5
tty: true
restart: 'always'
4. We launch the infrastructure with applications in development mode and check it through E2E tests
Commands
npm run pm2-full:dev:start
npm run pm2-full:dev:test:e2e
5. Adding a caching service to the WebhookModule
Creating a file 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}`;
}
}
User data is cached for 15 seconds, the caching time is set through the module configuration.
Updating the file 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;
}
// ...
In WebhookGuard we replace receiving data via ORM with receiving data from the keying service.
Updating the file 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);
}
}
//...
}
In the controller with user modification methods, we add a call to invalidate the cache when changing and deleting a user.
Updating the file 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' };
}
//...
}
Connect the caching service to the WebhookModule.
Updating the file libs/core/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,
],
//...
});

Conclusion
This post shows a simple way to cache and invalidate a cache. If there are more entities and data to cache, then you need to think of another way to cache and invalidate in order to write less code.
Plans
In the next post I will add getting server time via WebSockets and displaying it in an Angular application...
