This article analyzes and solves the problem of useRouter()
returning undefined
in Vue3 project after introducing public modules, and debugging shows that there is a conflict between two vue-router.mjs
files.
Problem description: The system management module (system) depends on the common module (common), which contains routing configuration (route.js) and Vue Router references. After publishing the common module to the intranet Nexus, after the system module is introduced into the common module, useRouter()
returns undefined
. The debugging shows that the project has two vue-router.mjs
files. However, using yarn link @ht/common
to introduce common module, the problem disappears.
The root cause of the problem: both the common module and the system module rely on vue-router. Since the common module is published to the intranet Nexus in the form of an npm package, the system module is installed through npm, resulting in two vue-router versions installed in the project, causing conflicts. yarn link
creates symbolic links, avoiding duplicate installations.
Solution: Make sure the project uses only one version of vue-router. The following methods are available:
Version consistency: Check
package.json
of common and system modules to ensure that the vue-router version is consistent. The version is inconsistent, so you need to adjust the vue-router version of one of the modules.Dependency enhancement: Remove vue-router from
dependencies
of the common module and declare it directly independencies
of the system module. The system module will install vue-router directly from the project root directory to avoid version conflicts. The routing configuration of the common module needs to be adjusted accordingly so that it no longer directly depends on vue-router.Module structure optimization: Reevaluate common module design. If the common module only provides common components and tool functions, the routing configuration should not be included. The routing configuration should be placed in the system module or a higher-level routing configuration module.
Through the above method, the vue-router version conflict can be effectively avoided and the problem of useRouter()
returning undefined
. The core is to ensure that only one version of vue-router in the project is loaded and used correctly.
The above is the detailed content of Vue-router.mjs conflict occurred after Vue3 project introduced public modules: How to solve the problem of useRouter() returning undefined?. For more information, please follow other related articles on the PHP Chinese website!

Node.js excels at efficient I/O, largely thanks to streams. Streams process data incrementally, avoiding memory overload—ideal for large files, network tasks, and real-time applications. Combining streams with TypeScript's type safety creates a powe

The differences in performance and efficiency between Python and JavaScript are mainly reflected in: 1) As an interpreted language, Python runs slowly but has high development efficiency and is suitable for rapid prototype development; 2) JavaScript is limited to single thread in the browser, but multi-threading and asynchronous I/O can be used to improve performance in Node.js, and both have advantages in actual projects.

JavaScript originated in 1995 and was created by Brandon Ike, and realized the language into C. 1.C language provides high performance and system-level programming capabilities for JavaScript. 2. JavaScript's memory management and performance optimization rely on C language. 3. The cross-platform feature of C language helps JavaScript run efficiently on different operating systems.

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.
