#NestJS

Has anyone found a way to use both GraphQL Shield and dataloaders at the same time while using Apollo Server and NestJS?

I recently found that because I have asynchronous calls being made in some of my shield rules, it's causing my dataloader batch functions to be called multiple times, when they should only be called once, which leaves me with the N+1 problem across my entire app.

I believe this is due to how dataloader requires that all of the batch function calls occur during the same event loop "tick", and the async calls in my shield rules are preventing this.

Here's where I asked the question on reddit

Optimize Your Nest.js App Performance With These Practices

In the modern era of rapid technological advancement, users tend to lose interest in using an application if it doesn’t load quickly. Since there are multiple alternatives available for each app, users are more likely to switch to another app if you don’t optimize your app.

A survey shows that if an app takes longer than three seconds to load, the probability of losing users increases by 40%. The optimization of an app is an essential factor that plays a critical role in the app’s success.

Nest.JS applications come equipped with a wide range of tools that developers can leverage. In this article, we will be exploring ways in which you can enhance your Nest.JS app’s performance by optimizing it effectively.

What is Nest.JS?

Nest.JS ranks among the popular JavaScript frameworks in 2023 that offer a robust set of tools for creating server-side applications, and native support for TypeScript elevates the development process to a higher level.

You can use Nest JS to develop sophisticated, high-performing, and scalable server-side applications. It provides you with a modular structure which makes it easier to organize the code. Additionally, it comes equipped with a range of tools and plugins that you can use to optimize your app. However, the overall performance of the application ultimately depends on the level of effort put in by the developer.

Here are some practices that can help you optimize your NestJS application to improve its performance and efficiency.

1. Implement Caching

Caching refers to the process of temporarily storing frequently accessed data in high-speed storage — cache memory. By activating caching, you can reduce the data retrieval time. Here’s how you can implement caching in your application.

Install Cache-Manager: NestJS provides a solution for implementing caching using cache-manager. To install it, run the following command:

$ npm install @nestjs/cache-manager cache-manager

This cache manager offers a unified interface that supports various cache storage providers beyond just the default in-memory option.

To enable in-memory caching, run the following command:

import { Module } from '@nestjs/common';

import { CacheModule } from '@nestjs/cache-manager';

import { AppController } from './app.controller';

@Module({

imports: [CacheModule.register()],

controllers: [AppController],

})

export class AppModule {}

To learn more about caching, you can explore additional resources and consider switching to alternative service providers.

2. Choose Appropriate Dependency Injection Library

Nest.JS provides developers with the sweet nectar of dependency injection. This design pattern allows for a more maintainable codebase by injecting dependencies as needed. But this blessing can also turn sour if not used properly, leading to sluggish application performance.

NestJS provides built-in support for dependency injection (DI), but it also allows you to use other DI libraries if you prefer. There are several popular DI libraries that are compatible with NestJS, including:

InversifyJS: InversifyJS is a powerful and flexible DI library that supports advanced features such as constructor parameter injection and named dependencies. It has a large community and well-documented resources for developers. You can use it with NestJS by installing the `@nestjs/inject` package and importing the `InversifyAdapter` from it.

Awilix: Awilix is a lightweight DI library that emphasizes simplicity and ease of use. It has a simple API and supports many of the same features as other DI libraries, such as constructor injection and property injection. You can use Awilix with NestJS by installing the `awilix` package and using the `awilix-express` integration library.

TypeDI: TypeDI provides a simple and intuitive API for defining and injecting dependencies. You can use TypeDI with NestJS by installing the `typedi` package and importing the `TypeDIAdapter` from the `@nestjs-typeorm` package.

tsyringe: tsyringe is a lightweight and flexible DI library that supports many advanced features such as circular dependencies and conditional injection. It has a simple and intuitive API, and you can find comprehensive documentation to work with the tsyringe. To use tsyringe with NestJS, you can install the `tsyringe` package and importing the `TsyringeAdapter` from the `@nestjs-modules/injection` package.

If you’re just getting started with NestJS and don’t have any particular requirements, the built-in DI system is a good choice as it is lightweight and easy to use.

3. Use Compression

The more code you have, the slower application will become. Therefore to prevent your app performance from getting bogged down by heavy code, you can use various compression techniques available to reduce the size of HTTP responses, JavaScript, and CSS files.

This technique includes Gzip, deflate, and Brotli compression. These tools or techniques can help you reduce the weight of your code, which will result in improved performance.

To use compression in NestJS, you can take the following steps:

1. Install the compression package:

npm install --save compression

2. Import the CompressionMiddleware from compression:

import * as compression from 'compression';

import { NestFactory } from '@nestjs/core';

import { AppModule } from './app.module';

async function bootstrap() {

const app = await NestFactory.create(AppModule);

// Use the compression middleware

app.use(compression());

await app.listen(3000);

}

bootstrap();

This file imports the compression middleware and adds it to the application using the app.use() method.

By default, the compression() middleware will use the gzip compression algorithm. You can also pass in options to customize the behavior of the middleware, such as the threshold at which responses will be compressed, using the following syntax:

app.use(compression({

threshold: 512 // set the threshold to 512 bytes

}));

With compression enabled, responses from your Nest.JS application will be compressed before they are sent to the client, reducing the amount of data that needs to be transferred over the network and improving performance.

4. Optimize database queries

You can enhance your app’s performance by optimizing your database queries. One effective method is to minimize the number of queries by utilizing query batching and compatible ORM frameworks that enable streaming and enhance the overall database process. Rather than retrieving all available data, reducing the amount of data fetched can also minimize the workload on the database and optimize its operations.

5. Revamp your Algorithm

To optimize an app’s performance, it’s essential to fine-tune its algorithm, which entails creating a series of instructions that direct the code on how to operate.

The algorithm’s defined steps have a direct impact on the app’s performance, as they dictate the optimal times and conditions for the code to perform specific tasks.

Evaluating the algorithm’s optimization level is critical to enhancing the app’s overall performance, as it informs the code when to execute particular tasks and when not to, enabling it to work more efficiently. Essentially, the algorithm acts as a roadmap for the code, guiding it on how to function for optimal efficiency.
