Build with production, code segmentation, externally load large libraries, adopt lightweight alternatives, analyze packaging volumes, optimize static resources, enable compression, ensure tree shake optimization, upgrade Vue3 and use Pinia to significantly reduce the packaging volume of Vue apps. 1. Use Vue production version to reduce the volume by more than 50%; 2. Use dynamic import to realize routes and component lazy loading; 3. Introduce lodash, moment and other libraries through CDN and externalize; 4. Use date-fns and dayjs to replace moment, and introduce lodash functions as needed; 5. Use report or visualizer to analyze dependency size; 6. Transfer image to WebP, compress, lazy loading and use srcset reasonably; 7

To create an HTML5 nested list, one list needs to be placed into the elements of another list. 1. It can be used or used as an outer and inner list, supporting mixed types; 2. The inner list must be nested directly inside the tag and cannot be placed outside; 3. All tags must be closed correctly to keep the structure valid; 4. The browser will automatically indent the nested list, and can also customize the style through CSS.

First, you should update Google Chrome, 1. Update Chrome to fix potential vulnerabilities; 2. Disable or remove extensions that cause problems; 3. Clear browsing data and caches to prevent data corruption; 4. Turn off hardware acceleration to avoid GPU driver conflicts; 5. Run Chrome cleaning tool to scan interfere with software; 6. Check and eliminate conflicting programs such as antivirus software; 7. Reset Chrome settings to restore default configuration; 8. Create new user configuration files to troubleshoot configuration corruption; 9. Run memory diagnosis to detect hardware problems such as RAM; 10. Finally, reinstall Chrome to ensure a clean environment. Most problems are caused by software. Hardware problems are rare but need to be investigated. Finally, STATUS_ACCESS_VIOL can be solved.

Integrated testing using SQLite in-memory databases can achieve a fast, isolated and real SQL behavior test environment; 2. Running real database containers (such as PostgreSQL) with Testcontainers can improve the authenticity of production environment simulations, but increase complexity and runtime; 3. The business logic test can be completely isolated through interface abstraction and injection simulation, which is suitable for scenarios that focus on logic rather than data persistence behavior; the choice plan should be based on the test depth: SQLite is used for data access logic, Testcontainers is used for query accuracy, and business logic is used for interface simulation.

First check the fault module, 1. Record the name of the fault module displayed on the blue screen. If it is a third-party driver such as antivirus software or graphics card driver, it is the focus of suspicion; 2. Update or roll back the graphics card, network card, antivirus software and other drivers, and priority is given to downloading the latest version from the manufacturer's official website; 3. Install all Windows system updates to repair known compatibility issues; 4. Run command prompt as an administrator to execute sfc/scannow and DISM/Online/Cleanup-Image/RestoreHealth to repair system files; 5. Run mdsched.exe to detect memory errors, and use CrystalDiskInfo to check hard disk health and system temperature; 6. Temporarily disable or uninstall

To resolve the "Yourconnectionisnotprivate" error, you should first manually enter http://192.168.1.1 to force the use of the HTTP protocol, because most home routers only support HTTP or use self-signed SSL certificates that the browser does not trust; 1. First try to enter http://192.168.1.1 directly in the address bar instead of https; 2. Clear the browser HSTS settings, enter chrome://net-internals/#hsts, and delete the security policy of 192.168.1.1; 3. Use privacy mode or change the browser to troubleshoot cache issues; 4. Check whether the router settings support disabling HT.

Go supports the core concept of functional programming, but requires manual implementation of some features. 1. Functions are first-class citizens and can be passed and returned as parameters, such as the higher-order function applyOperation; 2. Support anonymous functions and closures, such as counter functions maintain state through closures; 3. Do not force immutability, but can avoid modifying the original data by returning a new instance, such as the Move method returns a new Point; 4. Pure functions can be written, such as the add function has no side effects, improving testability; 5. Function combinations require custom compose functions because there are no built-in operators; 6. It is recommended to reduce side effects, such as avoiding modifying global variables, separate I/O logic from pure logic; 7. Support recursion, such as fac

To make the USB flash drive work normally on both macOS and Windows, you should select the exFAT file system. 1. Use "Disk Tools" on Mac, select the USB flash drive, format it as exFAT, and select MBR for the partition plan; 2. On Windows, you can right-click the USB flash drive to select formatting, select exFAT in the file system and check Quick format; 3. After formatting, you need to test the read and write function in both systems; pay attention to backing up the data before operation, because the formatting will clear all content, and finally achieve seamless cross-platform use.

Restart the computer and try again to solve the update timeout problem caused by temporary failures; 2. Run the Windows Update Troubleshooting Tool to automatically detect and fix common problems; 3. Restart Windows Update, BITS and encryption services to resolve service stuck or conflicts; 4. Rename the SoftwareDistribution folder to clear the damaged update cache; 5. Check the network connection to ensure stability and turn off the proxy or VPN; 6. Perform a clean boot to eliminate third-party software interference; 7. Update the network driver to ensure normal network communication. Usually, the 0x800705b4 error can be solved through the above steps, so that Windows updates can be restored to normal.

Object slicing occurs when the derived class object is passed or assigned to the base class object by a value, resulting in the loss of derived class members; 1. When the function parameter is the base class value type, passing the derived class object will trigger the slice, copying only the base class part; 2. Use pointers or references (such as constAnimal&) to avoid slicing, retaining the complete object type and virtual function behavior; 3. After slicing, the object type becomes a base class, and even if the virtual function exists, the derived class behavior cannot be restored; 4. Polymorphism should always be used with pointers or references to avoid value transfer. The correct way is to pass the object through references, thereby retaining the derived class information intact and calling the rewrite function correctly.

In JavaScript, modular development is implemented through export and import. 1. Use naming export to export multiple values, such as exportconstadd=(a,b)=>a b; 2. Use default export to export to export only one value, such as exportdefaultsayHello; 3. When importing, use curly export to export and keep the name consistent, such as import{add}from'./math.js'; 4. Default export to import does not require curly braces and can customize the name, such as importgreetfrom'./greeting.js'; 5. You can import both default and named exports, such as importg

To run the Docker container in background mode, you need to use the -d flag: 1. Use the dockerrun-d\ command, such as dockerrun-dnginx; 2. Ensure that the container has a continuous running process, otherwise it will exit immediately, and you can use the loop command to keep running; 3. Map the ports through the -p flag, such as dockerrun-d-p8080:80nginx to access the service; 4. Use --name to specify the container name for easier subsequent management, such as dockerrun-d-namemy-web-servernginx; 5. Use dockerlogs, dockerps, and dockerstop to view the log, status and control
