When using Composer in a production environment, you need to pay attention to safety, stability and performance. 1. Use composerinstall-no-dev to reduce unnecessary development dependencies and reduce online environment risks; 2. Always submit and rely on composer.lock files to ensure version consistency, and avoid using updates during deployment; 3. Optional configuration platform-check=false ignores platform differences warnings, which is suitable for building packaging scenarios; 4. Enable APCU to accelerate automatic loading to improve performance, especially suitable for high concurrency services, while paying attention to namespace uniqueness to avoid cache conflicts.

The rise of meme coins reflects the key role of community power and social media influence in the cryptocurrency market. 1. Dogecoin was originally a satirical joke and was born in 2013; 2. Driven by tweets from celebrities such as Elon Musk, the attention soared; 3. The market value once reached tens of billions of dollars, becoming a mainstream digital asset. Shiba Inu Coin is positioned as a "dogcoin killer" and has rapidly risen through community-driven strategies, building a decentralized exchange ShibaSwap, and relies on low-priced units to attract a large number of users to participate. Its success also depends on circulation guarantees on mainstream platforms such as Binance, Coinbase, and OKX. The core driving forces of meme coins include: 1. Viral transmission mechanism, rapid spread of information; 2. Enhanced sense of community belonging

To install the Composer plug-in, please first confirm that Composer is installed and the composer.json file exists, and then follow the following steps: 1. Make sure that Composer has been installed and created composer.json; 2. Search and copy the required plug-in name on Packagist; 3.

Verify whether the plug-in is effective and check compatibility and configuration. Follow these steps to correctly install the Composer plug-in.

Methods to manage database state in Laravel tests include using RefreshDatabase, selective seeding of data, careful use of transactions, and manual cleaning if necessary. 1. Use RefreshDatabasetrait to automatically migrate the database structure to ensure that each test is based on a clean database; 2. Use specific seeds to fill the necessary data and generate dynamic data in combination with the model factory; 3. Use DatabaseTransactionstrait to roll back the test changes, but pay attention to its limitations; 4. Manually truncate the table or reseed the database when it cannot be automatically cleaned. These methods are flexibly selected according to the type of test and environment to ensure the reliability and efficiency of the test.

The "reverse reference" in the currency circle, as the name suggests, refers to those reference objects whose views or operations are often opposite to the actual market trend. When such people or groups are extremely optimistic, the market may face a decline; when they are extremely pessimistic, the market may instead rebound. This is not to say that these people deliberately provide wrong signals, but that their judgments may deviate from the mainstream trends in the market, or that their operating behavior happens to be a catalyst for market reversal in a specific situation.

Laravel performance optimization can improve application efficiency through four core directions. 1. Use the cache mechanism to reduce duplicate queries, store infrequently changing data through Cache::remember() and other methods to reduce database access frequency; 2. Optimize database from the model to query statements, avoid N 1 queries, specifying field queries, adding indexes, paging processing and reading and writing separation, and reduce bottlenecks; 3. Use time-consuming operations such as email sending and file exporting to queue asynchronous processing, use Supervisor to manage workers and set up retry mechanisms; 4. Use middleware and service providers reasonably to avoid complex logic and unnecessary initialization code, and delay loading of services to improve startup efficiency.

To add dependencies to composer.json, the most common method is to use the composerrequire command, followed by manually editing the composer.json file. 1. Use composerrequiredor/package to automatically add the latest stable version dependencies and install them; 2. You can specify the version such as composerrequiredor/package: 1.2.3 or use the constraint character such as ^2.0; 3. This command will synchronize the update of composer.json and composer.lock and automatically handle the dependencies; 4. Manually edit suitable for batch addition or template projects, you need to maintain the version yourself and run c
