webpack Core idea frame

Webpack is a module bundler for modern JavaScript applications. This article mainly introduces the core concepts of the Webpack framework (organizing knowledge points). Friends in need can refer to

What is webpack

webpack It is a packaging tool for front-end construction (not a library or framework). It can process and use various resources, such as JS (including JSX), coffee, css (including less/sass), images, etc. as modules.

1. Basic knowledge points

 1.1 webpack is a module packager for modern JavaScript applications (module bundler). When webpack processes an application, it recursively builds a dependency graph that contains every module the application needs, and then packages all these modules into one or more bundles.

1.2 The four core concepts of webpack:

1.2.1 entry: entry point, entry starting point (there can be multiple), webpack will start from this starting point to find out which The file is what the entry file depends on, so as to build an internal dependency graph and process it and output it to a file called bundles

 1.2.2 output (output): Specify the bundle file processed by the entry point The output path (path) and name (filename) of Packaging and other processing; webpack loader essentially converts all types of files into modules that can be directly referenced by the application's dependency graph. It has two goals:

   1.2.3.1 Use the test attribute to identify the corresponding Convertible files for loader

  1.2.3.2 Use the use attribute to convert these files so that they are added to the dependency graph and eventually added to the bundle

  If you want to use webpack When defining loader in the configuration, it must be defined in module.rules instead of rules

 1.2.4 plugins: from packaging optimization and compression to redefining variables in the environment. The plug-in interface is extremely powerful and can handle a variety of tasks

  To use a plug-in, you only need to require() it and then add it to the plugins array. Most plugins can be customized through options. You can also use the same plug-in multiple times for different purposes in a configuration file. In this case, you need to create an instance of it by using the new operator.

    Webpack provides many plugins available out of the box! Check the plug-in list for more information. For more detailed pictures and texts, please refer to the official documentation https://doc.webpack-china.org/concepts/.

How to evaluate the cost-effectiveness of commercial support for Java frameworks How to evaluate the cost-effectiveness of commercial support for Java frameworks Jun 05, 2024 pm 05:25 PM

Evaluating the cost/performance of commercial support for a Java framework involves the following steps: Determine the required level of assurance and service level agreement (SLA) guarantees. The experience and expertise of the research support team. Consider additional services such as upgrades, troubleshooting, and performance optimization. Weigh business support costs against risk mitigation and increased efficiency.

How does the learning curve of PHP frameworks compare to other language frameworks? How does the learning curve of PHP frameworks compare to other language frameworks? Jun 06, 2024 pm 12:41 PM

The learning curve of a PHP framework depends on language proficiency, framework complexity, documentation quality, and community support. The learning curve of PHP frameworks is higher when compared to Python frameworks and lower when compared to Ruby frameworks. Compared to Java frameworks, PHP frameworks have a moderate learning curve but a shorter time to get started.

How do the lightweight options of PHP frameworks affect application performance? How do the lightweight options of PHP frameworks affect application performance? Jun 06, 2024 am 10:53 AM

The lightweight PHP framework improves application performance through small size and low resource consumption. Its features include: small size, fast startup, low memory usage, improved response speed and throughput, and reduced resource consumption. Practical case: SlimFramework creates REST API, only 500KB, high responsiveness and high throughput

Performance comparison of Java frameworks Performance comparison of Java frameworks Jun 04, 2024 pm 03:56 PM

According to benchmarks, for small, high-performance applications, Quarkus (fast startup, low memory) or Micronaut (TechEmpower excellent) are ideal choices. SpringBoot is suitable for large, full-stack applications, but has slightly slower startup times and memory usage.

Golang framework documentation best practices Golang framework documentation best practices Jun 04, 2024 pm 05:00 PM

Writing clear and comprehensive documentation is crucial for the Golang framework. Best practices include following an established documentation style, such as Google's Go Coding Style Guide. Use a clear organizational structure, including headings, subheadings, and lists, and provide navigation. Provides comprehensive and accurate information, including getting started guides, API references, and concepts. Use code examples to illustrate concepts and usage. Keep documentation updated, track changes and document new features. Provide support and community resources such as GitHub issues and forums. Create practical examples, such as API documentation.

How to choose the best golang framework for different application scenarios How to choose the best golang framework for different application scenarios Jun 05, 2024 pm 04:05 PM

Choose the best Go framework based on application scenarios: consider application type, language features, performance requirements, and ecosystem. Common Go frameworks: Gin (Web application), Echo (Web service), Fiber (high throughput), gorm (ORM), fasthttp (speed). Practical case: building REST API (Fiber) and interacting with the database (gorm). Choose a framework: choose fasthttp for key performance, Gin/Echo for flexible web applications, and gorm for database interaction.

What are the common misunderstandings in the learning process of Golang framework? What are the common misunderstandings in the learning process of Golang framework? Jun 05, 2024 pm 09:59 PM

There are five misunderstandings in Go framework learning: over-reliance on the framework and limited flexibility. If you don’t follow the framework conventions, the code will be difficult to maintain. Using outdated libraries can cause security and compatibility issues. Excessive use of packages obfuscates code structure. Ignoring error handling leads to unexpected behavior and crashes.
