nodejs 8.11 performance improvements

With the rapid development and widespread adoption of Node.js, and the pressure for more efficient performance, Node.js 8.11 has been released with some major performance improvements. These improvements cover improvements in the language itself, improvements in the V8 engine, and other improvements. In this article, we'll dive into the specifics of these performance improvements.

1. New JavaScript standard support

Node.js 8.11 adds a V8 engine version that supports all new features in ES2017 - V8 6.1. This means that using new ES2017 methods such as Object.values, Object.entries and String padding in Node.js does not require the use of third-party libraries.

At the same time, Node.js 8.11 also supports some new ECMAScript proposals, including asynchronous iterators and generator functions, which can make the process more readable and easier to maintain.

2. More efficient memory management

In Node.js 8.11, V8 provides new memory limits for 64-bit architectures. This can help Node.js run in larger-scale applications and handle larger memory requirements more efficiently. This means that Node.js can be more reliable and stable, and its predictability has also been improved during the "peak period" of client requests and the need to respond quickly.

3. Fast startup time

Node.js 8.11 makes application startup time faster by increasing require() speed and optimizing the module loading algorithm. Developers can see a 60% improvement in startup times, and in large-scale applications, fast startup times are critical. This improvement allows developers to focus more on the business logic and functionality of the application, rather than requiring users to wait for a long startup process.

4. Faster asynchronous processing

Node.js 8.11 adds the async_hooks API. This API enables custom asynchronous call chains to be quickly built. At the same time, it also provides a unified interface for listening to asynchronous events. This is a significant improvement for large-scale applications, helping developers build high-load applications quickly and efficiently, and achieve better controllability and stability.

5. Node.js CLI improvements

Node.js 8.11 has some better features and options built into npm, the most commonly used command in the CLI. One of the major improvements includes:

• Faster and more stable npm installation method
• Parallel and serial installation methods. This means increased application build speed and stability.
• Interactive installation command, users can better understand the operations and progress being performed
• The npm audit command provides a better way to find security vulnerabilities and recommend updating and upgrading dependent packages.

6. Other small improvements

In Node.js 8.11 and later versions, the platform has improved certain functions and APIs to improve Node.js code maintainability and reusability. The following are several small improvements related to this:

• Console panel improvements: Provides a better interface for observing monitoring and analyzing real-time logs.
• Better HTTP2 support: Node.js 8.11 and later versions provide better support for HTTP2 frameworks such as Cloudflare and Koa.
• SIGBREAK signal support: Supports Windows platform (the adapted Bash on Windows is not currently supported).

Some of the major improvements and updates listed above are actually just part of this Node.js 8.11 update. This also highlights the development team's efforts and commitment to continuously improve the Node.js platform. Whether you are a developer, business person, manager, etc., these improvements are beneficial, and they may be a decisive factor in improving the user experience of the application.

Summary

The performance improvements in Node.js 8.11 are optimized from the inside out to improve the functionality and performance of your applications. This article provides a brief overview of the important performance improvements in Node.js 8.11. Developers can use these improvements and features to build more effective applications faster and more reliably. These improvements and features will keep Node.js growing strongly among the developer community, making it one of the most popular development frameworks in the future.
