Why is Fastify faster than Express?
Fastify provides full encapsulation for plug-ins, automatically parses JSON with relatively faster rendering, and provides quick routing. Among other benefits, Fastify also has a cleaner syntax for writing async code in controllers. Express, however, has a stronger user base with plenty of documentation available.
Conclusion. Fastify is around 20% faster than Express in almost every request. The only exception is a request with an empty response (possible due to an issue with a code).
Fastify is built as a general-purpose web framework, but it shines when building extremely fast HTTP APIs that use JSON as the data format. These are extremely common in both web and mobile software architectures, so Fastify could improve the throughput of the majority of applications.
The key difference between Koa and Express is how they handle middleware. Express includes routing and templates in the application framework. Koa, on the other hand, requires modules for these features, therefore making it more modular or customizable.
Nest offers a ready-to-use application architecture using controllers, providers, and modules. This enables developers and teams create applications that are simple to test and maintain. Express does not require a specific structure, which can provide flexibility for small or one-person development teams.
As we can see fastify is consistently faster than express by 2 - 3 seconds. By average, we can calculate that fastify needs 6.27 seconds while express need 8.6 seconds. Fastify is the winner with 27.3% faster.
1. Fastest Train in India 2019: Vande Bharat Express - Train 18 (22439), Max Speed- 180 km/h. With a top speed of 180 km/hr, the super-fast train is functioned to run at 160 km/hr on the train tracks for safety purposes.
Fastify is a web framework highly focused on providing the best developer experience with the least overhead and a powerful plugin architecture. It is one of the fastest web frameworks in town. Fastify is twice as fast as Express.
The Fastify module exports a factory function that is used to create new Fastify server instances. This factory function accepts an options object which is used to customize the resulting instance. This document describes the properties available in that options object. Factory. http2.
By default, Nest makes use of the Express framework. As mentioned earlier, Nest also provides compatibility with other libraries such as, for example, Fastify.
Is Express the best framework?
In fact, it's quite suitable for almost any kind of web and mobile application development from small to large scale. For development teams at beginner levels, Express is the best choice since there's outstanding community support available for this framework.
Express augments and extends the the native NodeJS req and res objects. Koa replaces them entirely with a Context object ctx . The Context object has ctx. request and ctx.
koa is incompatible with express middleware.
Nest extends Node. js frameworks like Express or Fastify adding modular organization and a wide range of other libraries to take care of repetitive tasks. It's open-source, uses TypeScript, and is a very versatile Node. js framework for building backend systems.
In addition to traditional (sometimes called monolithic) application architectures, Nest natively supports the microservice architectural style of development.
Performance is one of the key features of any good framework, and NestJS is a big hit among developers when it comes to performance. Since NestJS integrates with Node. js and modules like Express and Fastify, it can quadruple developers' productivity and application performance while saving time.
To validate incoming requests, Fastify uses JSON Schema. This example shows how to pass an options object to the route, which accepts a schema key that contains all of the schemas for route, body , querystring , params , and headers . Read Validation and Serialization to learn more.
restify is a node. js module purpose built to create REST web services in Node. restify makes lots of the hard problems of building such a service, like versioning, error handling and content-negotiation easier.
MERN stack is a collection of technologies that enables faster application development. It is used by developers worldwide. The main purpose of using MERN stack is to develop apps using JavaScript only. This is because the four technologies that make up the technology stack are all JS-based.
Mail trains are kind of same as express trains and generally have less average speed and have more stoppages. Maharashtra Sampark Kranti Express is the fastest Mail Express train in India. Express and Mail train number starts with 1xxxx or 2xxxx and average speed is below 50 km/h.
Which train is fast mail or express?
Regular Express rail service of India are known as Mail Express Trainsrun express where there is overlapping local train service available, and run local at the tail ends of the line. An express train is one where the average speed, excluding halts, is greater than 36 kmph.
direct or fast, especially making few or no intermediate stops: an express train; an express elevator. used for direct or high-speed travel: an express highway.
Train Numbers starting with first two digits as 12 or 22 are super fast trains. Remaining are express trains.
