Webpack can convert multiple static resources js, css and less into a static file, and reduces page requests. That is, Webpack analyzes the project structure, finds out the development language (Scss, TypeScript, etc.) that the JavaScript module and some other browsers cannot directly run, and converts and packages the development language into a suitable format for the browser to use. However, when the existing webpack imports a file, the webpack searches for corresponding directories from an upper level in sequence according to the imported file, and after a project is large, the performance consumption and the click feeling are obvious. For example, in the field of education, the operation of importing files by webpack is very common, so a scheme for improving the retrieval speed is urgently needed.

Detailed Description
The present invention provides a method for improving search speed based on an educational system and an electronic device, and the present invention is further described in detail below in order to make the purpose, technical solution and effect of the present invention clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for increasing a search speed according to a preferred embodiment of the present invention, which includes the steps of:
s1, reading the converter configuration of the module packer in advance, and setting file matching information through the converter configuration;
s2, designating the folder directory of the third party library as the folder under the root directory, and designating the priority matching entry file of the third party library as main.
The method adds a plurality of optimized query modes for the imported file, skips some additional recursive analysis operations, and reduces the pause feeling of the card and the performance consumption. And meanwhile, a matched folder is designated, the matching range is narrowed, and the purpose of optimizing the performance, namely the purpose of improving the retrieval speed of the module packer is achieved.
In step S1, the converter configuration of the module packer is read first. The file matching information is set by the converter configuration.
The setting of the file matching information specifically comprises setting a cacheDirectory option of the converter, enabling the converter to support cache conversion, and modifying an include parameter of the converter to narrow a matching range.
The converter is a loader (or a loader), and the loader is used for converting the source code of the module, so that the file is preprocessed when the module is imported or "loaded". loaders are similar to "tasks" in other build tools and provide a powerful way to handle front-end build steps.
For example, vue-loader is a Webpack loader that can convert Vue components written in a specified format into JavaScript modules.
The characteristics of the loader are: the loaders can be connected in series and applied to pipeline resources, the last loader returns javascript, and other loaders can return any format (transmitted to the next loader); loaders can be synchronous or asynchronous; loaders run under nodejs and can be used as all possible loader acceptance parameters for configuration; loaders can bind to extension/RegExps configurations; loaders can publish and install normal modules at npm, one at a time; loaders can access configuration plugins besides loaders to give loaders more features; loaders may release any additional files.
The loader mainly comprises: loader for preprocessing and loader for js processing. Wherein the preprocessed loader comprises: the css-loader can solve the problems of path reference and the like in the css; style-loader, which can dynamically write the style into cs; sass-loader, scss compiler; less-loader, less compiler; postcss-loader, scss reprocessing.
The loader processed by js mainly comprises the following steps: babel-loader, which can convert ES6 code; jsx-loader can recognize jsx syntax in js
Other loader loaders mainly include: the url-loader is used for processing an npm install-save-dev url-loader; the file-loader is used for loading an npm instance-save-dev file-loader; the json-loader is used for json processing npm install-save-dev json-loader; raw-loader for html processing npm install-save-dev raw-loader
loaders is an array, each object in the array uses a regular expression, and a pairing scheme is corresponding to the regular expression. The loader is used for loading different files into the js file, for example, the url-loader is used for loading the png/jpg format picture file in js; the css/style loader is used for loading css files; the less-loader compiles less into cs files; different processors pass! Separated and connected in series.
The cacheDirectory option of the converter is set because the cache is performed in the loader conversion process, the cache is read before each conversion, and if the cache result exists, the cache result is directly fetched without extra repeated calculation.
The cacheDirectory default is false. If this parameter is set, the converted result will be buffered.
When webpack is compiled again, it will first try to read the translation result (i.e. the cached result) from the cache, thereby avoiding wasting resources.
If the value is null (loader: 'babel-loader directory'), the loader will use the system default temporary file directory.
And modifying the include parameter of the converter to narrow the matching range so as to only match the specified folder, but directly ignore other folders, narrow the matching range and accelerate the matching speed. Files (folders) which have to be processed can be added through an include parameter, and files (folders) which do not need to be processed can be shielded through an include parameter.
In addition, setting the file matching information further includes removing the multi-file matching configuration. For example, in the case of a match jsx, if there is no jsx file, then only js needs to be matched, thus removing jsx the compatible settings of the match.
In the step S2, the folder directory of the third party library is designated as the folder under the root directory, and the priority matching entry file of the third party library is designated as main.
Modules, in particular, specify the folder directory of the third party library as the folder under the root directory by configuring the reset. Thus, when the third-party module is loaded, the folder under the root directory can be directly searched without extra query time.
Modules are directories that should be searched when telling the webpack resolution module. Both absolute and relative paths can be used, but there is also a difference: by looking at the current directory and ancestor paths (i.e./Node _ modules,./Node _ modules, etc.), the relative paths will be looked up in a manner similar to Node looking up 'Node _ modules'. Using absolute paths, only a given directory will be searched.
The method comprises the steps that the prior matching entry file of the third-party library is designated as main.js, so when the third-party module is loaded, the webpack can find the main.js preferentially, the file is tried to be matched as the entry file, the module is loaded if the matching is successful, the real entry file is continuously and recursively inquired if the matching is failed, and a great deal of time can be saved by adopting the method because most of the entry files of the third-party library are main.js. Js is the entry provided to webpack, which packages the files used to retrieve by main. Js, for example, imported vue, then webpack would find vue files to pack.
Further, the step S2 further includes: suffixes are omitted when modules that import the same suffix are provided.
Further, the step S2 further includes: the arrangement is such that the matching is performed using a relatively short suffix at the matching module. For example, for js and json, js matching can be used directly, and when a module is introduced, js and json are not introduced, but directly introduced, so that repeated matching is not caused during matching, and the matching time is reduced.
Further, the step S2 further includes: setting to not parse a predetermined third party library.
Some third party libraries are already mature, such as exact. js and jquery. js, and compressed files do not use modularization, so webpack requires additional parsing time, sets it to be unresolved, and reads the file directly by the browser, thereby reducing the additional parsing time.
Act is a JAVASCRIPT library used to construct user interfaces. React is mainly used to construct UIs, and many consider React as V (view) in MVC. The act originates from the Facebook's internal project, is used to set up the Instagram's website, and is sourced 5 months in 2013. The act has higher performance and the code logic is very simple, and more people have started to pay attention to and use the act.
jquery is a fast, compact JavaScript frame, which is another excellent JavaScript code base (or JavaScript frame) after Prototype. The aim of jQuery design is "write Less, Do More", i.e. advocate writing Less code and doing More. The method encapsulates functional codes commonly used by JavaScript, provides a simple JavaScript design mode, and optimizes html document operation, event processing, animation design and Ajax interaction. The core characteristics of jQuery can be summarized as: the multifunctional interface has unique chain grammar and short and clear multifunction; the CSS selector is efficient and flexible, and the CSS selector can be expanded; the method has a convenient plug-in extension mechanism and abundant plug-ins. The jQuery is compatible with various mainstream browsers, such as IE 6.0+, FF 1.5+, Safari 2.0+, Opera 9.0+, and the like.
