What is the usage of $on in vue

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.

1. The first choice for the Laravel MySQL Vue/React combination in the PHP development question and answer community is the first choice for Laravel MySQL Vue/React combination, due to its maturity in the ecosystem and high development efficiency; 2. High performance requires dependence on cache (Redis), database optimization, CDN and asynchronous queues; 3. Security must be done with input filtering, CSRF protection, HTTPS, password encryption and permission control; 4. Money optional advertising, member subscription, rewards, commissions, knowledge payment and other models, the core is to match community tone and user needs.

1. PHP mainly undertakes data collection, API communication, business rule processing, cache optimization and recommendation display in the AI content recommendation system, rather than directly performing complex model training; 2. The system collects user behavior and content data through PHP, calls back-end AI services (such as Python models) to obtain recommendation results, and uses Redis cache to improve performance; 3. Basic recommendation algorithms such as collaborative filtering or content similarity can implement lightweight logic in PHP, but large-scale computing still depends on professional AI services; 4. Optimization needs to pay attention to real-time, cold start, diversity and feedback closed loop, and challenges include high concurrency performance, model update stability, data compliance and recommendation interpretability. PHP needs to work together to build stable information, database and front-end.

When choosing a suitable PHP framework, you need to consider comprehensively according to project needs: Laravel is suitable for rapid development and provides EloquentORM and Blade template engines, which are convenient for database operation and dynamic form rendering; Symfony is more flexible and suitable for complex systems; CodeIgniter is lightweight and suitable for simple applications with high performance requirements. 2. To ensure the accuracy of AI models, we need to start with high-quality data training, reasonable selection of evaluation indicators (such as accuracy, recall, F1 value), regular performance evaluation and model tuning, and ensure code quality through unit testing and integration testing, while continuously monitoring the input data to prevent data drift. 3. Many measures are required to protect user privacy: encrypt and store sensitive data (such as AES

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.

1. The mainstream frameworks of PHP e-commerce backend include Laravel (fast development, strong ecology), Symfony (enterprise-level, stable structure), Yii (excellent performance, suitable for standardized modules); 2. The technology stack needs to be equipped with MySQL Redis cache, RabbitMQ/Kafka message queue, Nginx PHP-FPM, and front-end separation is considered; 3. High concurrency architecture should be layered and modular, database read and write separation/distributed database, accelerated with cache and CDN, asynchronous processing of tasks, sharing of load balancing and Session, gradually microservice, and establish a monitoring and alarm system; 4. Multiple monetization paths include product price difference or platform commission, site advertising, SaaS subscription, customized development and plug-in market, API connection
