SVG (ScalableVectorGraphics) is a text-based vector graphics format that can be directly embedded in HTML to achieve high-quality graphics display. 1.SVG is stored in XML format, and defines shapes, colors and positions through tags, and supports drawing of complex graphics such as circles, rectangles, and paths; 2. HTML can be embedded through inline code, tags, CSS background images, or other methods; 3. Compared with PNG or JPEG, SVG has the advantages of resolution irrelevance, small file size, strong editability, and support CSS and JavaScript interaction; 4. When using it, it is recommended to set width and height attributes, optimize accessibility, test cross-device compatibility, and use development tools for debugging.

nextTick is used in Vue to execute code after DOM update. When the data changes, Vue will not update the DOM immediately, but will put it in the queue and process it in the next event loop "tick". Therefore, if you need to access or operate the updated DOM, nextTick should be used; common scenarios include: accessing the updated DOM content, collaborating with third-party libraries that rely on the DOM state, and calculating based on the element size; its usage includes calling this.$nextTick as a component method, using it alone after import, and combining async/await; precautions include: avoiding excessive use, in most cases, no manual triggering is required, and a nextTick can capture multiple updates at a time.

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.

Managing environment variables in Vue applications requires specific rules and using .env files. First, only variables prefixed with VUE_APP_ will be exposed to the application; second, different environments correspond to different .env files, such as .env.development, .env.production, etc.; third, variables are injected during construction and cannot be changed at runtime. The specific steps include: 1. Create .env files in the project root directory; 2. Use the corresponding .env files according to the pattern, such as .env.staging; 3. Access variables through process.env in the code; 4. You can import the variables into config.js for unified management; 5. If you need multiple environments to support, you can use package
