Description

Technical Field

[0001] The present invention relates to the field of software development and automation tools, and in particular to the field of download optimization and acceleration technology for npm package managers. Background Art

[0002] npm is a package manager for Node.js (JavaScript runtime). It is an open source command-line tool for installing, updating, and managing Node.js modules. npm is the official module manager for Node.js. It allows users to download and install public Node.js modules from a centralized repository and integrate these modules into their own applications. npm allows users to download and install public Node.js modules from the npm repository. Modules can be quickly installed using the npm command. npm provides the ability to manage modules, including upgrading and deleting modules. npm allows developers to publish their own modules to the npm repository for other developers to use.

[0003] The technology based on npm source download dependency has the following main disadvantages:

[0004] (1) High configuration complexity: Existing systems often require users to manually configure multiple npm sources and manually switch between them when using them, which increases the user's operational complexity. Users need to understand the characteristics and stability of each source in order to make a reasonable choice.

[0005] (2) Insufficient intelligence: Although some existing systems provide intelligent switching functions, their evaluation mechanisms and switching logic may not be precise and flexible enough to fully adapt to complex network environments and user needs.

[0006] (3) Lack of unified management configuration: Most existing systems lack a unified management configuration. Users need to use multiple tools or command line interfaces to manage npm sources and download tasks, which increases the difficulty and complexity of management.

[0007] (4) High update and maintenance costs: The existing system needs to be updated and maintained regularly to ensure the stability and security of its functions. However, with the rapid development and changes in the npm ecosystem, the cost of updating and maintaining the system may continue to increase. Summary of the invention

[0008] The purpose of this invention is to mainly solve the problems that may be encountered in the process of downloading npm packages, such as single source, slow download speed, poor stability, etc., and to achieve a more efficient package download experience by automatically switching multiple npm sources. The system is equipped with automation and intelligent decision-making capabilities, and can automatically select the best npm source for downloading according to preset rules or real-time network conditions. The automation and intelligent features greatly reduce the user's operating burden and improve download efficiency.

[0009] The technical solution of the present invention is: a multi-source intelligent switching system based on npm package download, which designs a more accurate evaluation mechanism and a more flexible switching logic, by monitoring the average response time of each npm source to requests, including the first response time and the response time of subsequent requests. The speed of downloading packages from each source is detected in real time, measured in KB / s, and its stability is evaluated by recording indicators such as the availability and error rate of the source and outputting them to the console; the results of the source are dynamically evaluated according to the current network environment, the priority of the download task, and the weight value of each source, and the optimal source is dynamically selected for downloading. The system continuously monitors the performance of each source during the download process, and adjusts the switching strategy in real time according to the actual situation.

[0010] If the currently selected source has performance degradation or failure, the system will immediately switch to the alternative source to ensure that the download task is not affected. The system has a built-in efficient error handling and recovery mechanism that can quickly respond and try to recover or switch to a new source for downloading when encountering errors or abnormal situations. This is to adapt to complex network environments and user needs. Through network smoothness, network speed and other aspects of detection, the source selection is intelligent and automated.

[0011] The present invention can significantly improve the user experience in the npm package management process by intelligently switching strategies, optimizing download speed and stability, and providing user-friendly configuration and configuration options.

It improves the user's manual operation and time cost, improves the success rate and efficiency of download tasks, and enhances user satisfaction. The intelligent switching strategy can automatically select the best npm source for download according to the real-time network status and preset rules, effectively solving the problems of single source, slow download speed and poor stability. By monitoring the response time, download speed and stability of the source, the system can adjust the switching strategy in real time to ensure the efficient completion of the download task. By dynamically evaluating the performance of the source and the current network environment, the system can select the best download source to improve the download speed and stability. In addition, the system has a built-in efficient error handling and recovery mechanism, which can respond quickly and try to resume downloads when encountering abnormal situations, reduce the risk of download interruptions, and optimize download speed and stability. This system provides a simple and easy configuration method for users to conduct unified management and operation. This design reduces the difficulty and complexity of user management and improves management efficiency. Users can easily set the npm source download order, rules, and view download progress and log information. At the same time, the system also supports custom switching strategies, allowing users to flexibly configure according to their needs, improving the user experience.

[0014] By intelligently switching sources, the system of the present invention can also effectively avoid the problem of download interruption caused by single source failure. Although the system of the present invention is mainly oriented to automation and intelligence. The system of the present invention needs to provide a friendly configuration source file so that users can conveniently set the download order and rules, view download progress and log information, etc.

[0015] The present invention also aims to solve the following key technical problems: simplify the configuration process, provide a simple and easy-to-use configuration method, and easily add, delete and automatically switch npm sources according to rules, reducing the complexity of operation. Such as global installation path, cache path, personalized source address list and other information configuration.

[0016] The present invention improves the user experience in the process of npm package download management through intelligent switching strategy, optimization of download speed and stability, and provision of user-friendly configuration and configuration options. It improves the user's manual operation and time cost, improves the success rate and efficiency of download tasks, and enhances user satisfaction. The intelligent switching strategy can automatically select the best npm source for downloading according to the real-time network status and preset rules, effectively solving the problems of single source, slow download speed and poor stability. By monitoring the response time, download speed and stability of the source, the system can adjust the switching strategy in real time to ensure the efficient completion of the download task. By dynamically evaluating the performance of the source and the current network environment, the system can select the optimal download source to improve the download speed and stability. In addition, the system has a built-in efficient error handling and recovery mechanism, which can respond quickly and try to resume downloading when encountering abnormal situations, reduce the risk of download interruption, and optimize download speed and stability. The system of the present invention provides a simple and easy configuration method, which is convenient for users to carry out unified management and operation. This design reduces the management difficulty and complexity of users and improves management efficiency. Users can easily set the npm source download order, rules and view information such as download progress and logs.

[0017] The present invention improves the intelligence level: optimizes the system performance: improves the system architecture design, optimizes the resource allocation strategy, provides a fault-tolerant mechanism, and improves the reliability and availability of the system. Dynamically adjust the resource allocation strategy according to the current load and resource usage of the system. Increase resource investment during the peak period of download tasks to ensure the smooth progress of download tasks. Introduce a priority scheduling mechanism to allocate system resources according to the priority of download tasks. High-priority tasks can obtain more resource support, thereby completing the download faster. When an error occurs during the download process, the system should be able to automatically handle the error and attempt to retry. For example, when downloading from a certain source fails, the system can automatically switch to other sources for retrying. Provide a unified configuration: Develop a unified management configuration that integrates npm source management, download task monitoring, log viewing and other functions to facilitate users to perform unified management and operation.

[0018] Beneficial effects: 1) The present invention has a higher degree of intelligence. Compared with the prior art, it may only provide basic source switching functions and lacks intelligent evaluation mechanism and flexible switching logic.
