To create a custom Vue build, first prepare the development environment, including installing Node.js, npm and cloning the official repository; secondly, modify the source code in the src directory according to the needs, such as deleting modules or adding instructions; then configure the build options in scripts/config.js, use Rollup to package and add plug-ins such as terser compression; finally execute the npm run build build and publish it to a private CDN or npm registry. 1. Prepare the development environment: install Node.js, npm, clone the official Vue repository and install the dependencies. 2. Modify the source code: adjust the core logic, add and delete modules or add built-in instructions in the src directory. 3. Configure the build output: Edit the config.js file, select the packaging format, crop the module and add the compression plug-in. 4. Execute build and release: Run the build command, upload the file generated by dist to the CDN or npm registry as needed and update the documentation description.
You may have used the default build version of Vue, but sometimes you need to customize the build to meet specific needs, such as reducing volume, integrating special features, or adapting to certain older systems. At this time, you need to create a custom Vue build by yourself.
1. Prepare for the development environment
To start building your own version of Vue, you must first make sure that Node.js and npm (or yarn, pnpm) are installed in the local environment. Then clone the official repository from GitHub:
git clone https://github.com/vuejs/vue.git cd vue
Next install the dependencies:
npm install
Once this step is complete, you have all the tools and libraries you need to build.
- Make sure your Git is configured correctly, so as to facilitate subsequent submissions and modifications.
- It is recommended to use VS Code or WebStorm to edit the source code, which is more convenient to debug.
- If you just want to change something, you can first find the corresponding file in the
src
directory without having to build the configuration.
2. Modify the source code to meet customization needs
Vue has clear source code structure, and the main codes are all in src/
directory. You can modify the core logic according to your needs, add plug-in entry points, or delete unused modules.
For example, if you want to remove the warnings that are not supported by ES5 in Vue, you can directly delete the relevant prompt code; or if you want to build a common command (such as v-focus
), you can add it during the compilation stage.
- It is best to run the test before modifying:
npm run test
- It is recommended to use feature branches to make changes to avoid polluting the main branches.
- If it is used in a production environment, be sure to do a full test
3. Configure the build output options
Vue is packaged using Rollup and build configurations are in scripts/config.js
. You can define different build goals here, such as only the runtime version, the full version with the compiler, or the UMD format, etc.
For example, if you want to generate a compressed .min.js
file, you can add the terser
compression tool to the rollup plugin:
import { terser } from 'rollup-plugin-terser' // Add plugins to the corresponding configuration: [ // Other plugins... terser() ]
- Supports multiple formats (umd, esm, cjs), select on demand
- Different entry files can be specified to realize module cropping
- The build results will be placed in
dist/
directory
4. Execute build and publish
When everything is ready, execute the build command:
npm run build
After the build is complete, you will see multiple version files generated in dist/
directory. If you plan to share with the team or publish publicly, you can call the tag and push it to the remote repository, or publish it to a private npm registry.
- The built file naming is recommended with the version number or purpose identifier.
- If used in the company's internal project, it can be uploaded to a private CDN to speed up access
- Remember to update README or CHANGELOG before publishing to indicate the changes
Basically these steps. Although the whole process seems a bit complicated, as long as you get familiar with it once, it will be very quick to adjust it in the future.

HeadlessUIinVue refers to a library of UI components that provide no preset styles and only contains core logic and behavior. Its features include: 1. No style restrictions, developers can customize the design; 2. Focus on barrier-free and interactive logic, such as keyboard navigation, state management, etc.; 3. Support Vue framework integration, exposing the control interface through combinable functions or components. Reasons for use include: maintaining design consistency, built-in accessibility, strong component reusability, and lightweight library size. In practical applications, developers need to write HTML and CSS themselves. For example, when building a drop-down menu, the library handles state and interaction, while developers decide on visual presentation. Mainstream libraries include HeadlessUI and RadixVue for TailwindLabs, suitable for

In Vue3, there are three ways to monitor nested properties using the watch function: 1. Use the getter function to accurately monitor specific nested paths, such as watch(()=>someObject.nested.property,callback); 2. Add the {deep:true} option to deeply monitor changes within the entire object, which is suitable for situations where the structure is complex and does not care about which property changes; 3. Return an array in the getter to listen to multiple nested values ??at the same time, which can be used in combination with deep:true; in addition, if ref is used, the nested properties in its .value need to be tracked through getter.

Building a Vue component library requires designing the structure around the business scenario and following the complete process of development, testing and release. 1. The structural design should be classified according to functional modules, including basic components, layout components and business components; 2. Use SCSS or CSS variables to unify the theme and style; 3. Unify the naming specifications and introduce ESLint and Prettier to ensure the consistent code style; 4. Display the usage of components on the supporting document site; 5. Use Vite and other tools to package as NPM packages and configure rollupOptions; 6. Follow the semver specification to manage versions and changelogs when publishing.

Vue3 has improved in many key aspects compared to Vue2. 1.Composition API provides a more flexible logical organization method, allowing centralized management of related logic, while still supporting Vue2's Options API; 2. Better performance and smaller package size, the core library is reduced by about 30%, the rendering speed is faster and supports better tree shake optimization; 3. The responsive system uses ES6Proxy to solve the problem of unable to automatically track attribute addition and deletion in Vue2, making the responsive mechanism more natural and consistent; 4. Built-in better support for TypeScript, support multiple node fragments and custom renderer API, improving flexibility and future adaptability. Overall, Vue3 is a smooth upgrade to Vue2,

? in regular expressions are used to convert greedy matches to non-greedy, achieving more accurate matches. 1. It makes the content as little as possible to match as little as possible to avoid mismatch across tags or fields; 2. It is often used in scenarios such as HTML parsing, log analysis, URL extraction, etc. that require precise control of the scope; 3. When using it, it is necessary to note that not all quantifiers are applicable. Some tools need to manually enable non-greedy mode, and complex structures need to be combined with grouping and assertions to ensure accuracy. Mastering this technique can significantly improve text processing efficiency.

Deploying Vue applications to production environments requires optimization of performance, ensuring stability and improving loading speed. 1. Use VueCLI or Vite to build a production version, generate a dist directory and set the correct environment variables; 2. If you use VueRouter's history mode, you need to configure the server to fallback to index.html; 3. Deploy the dist directory to Nginx/Apache, Netlify/Vercel or combine CDN acceleration; 4. Enable Gzip compression and browser caching strategies to optimize loading; 5. Implement lazy loading components, introduce UI libraries on demand, enable HTTPS, prevent XSS attacks, add CSP headers, and restrict third-party SDK domain names to enhance security.
