Function anti-shake is an optimization technique used to handle frequently triggered events. The implementation steps include: 1. Set a timer, clear the previous timer and reset the new timer every time the event is triggered; 2. If there is no new event trigger within the timer time, execute the defined function.

The steps to create a package in Laravel include: 1) Understanding the advantages of packages, such as modularity and reuse; 2) following Laravel naming and structural specifications; 3) creating a service provider using artisan command; 4) publishing configuration files correctly; 5) managing version control and publishing to Packagist; 6) performing rigorous testing; 7) writing detailed documentation; 8) ensuring compatibility with different Laravel versions.

Composer.json's autoload configuration is used to automatically load PHP classes, avoiding manual inclusion of files. Use the PSR-4 standard to map the namespace to a directory, such as "App\":"src/" means that the class under the App namespace is located in the src/ directory; classmap is used to scan specific directories to generate class maps, suitable for legacy code without namespace; files are used to load a specified file each time, suitable for function or constant definition files; after modifying the configuration, you need to run composerdump-autoload to generate an automatic loader, which can be used in the production environment --optimize or --classmap-

The digital asset market attracts global attention with its high volatility. In this environment, how to steadily capture returns has become the goal pursued by countless participants. Quantitative trading, with its dependence on data and algorithm-driven characteristics, is becoming a powerful tool to deal with market challenges. Especially in 2025, this time node full of infinite possibilities is combined with the powerful programming language Python to build an automated "brick-moving" strategy, that is, to use the tiny price spreads between different trading platforms for arbitrage, which is considered a potential way to achieve efficient and stable profits.

Packagist is Composer's default package repository for centralized management and discovery of PHP packages. It stores the metadata of the package instead of the code itself, allowing developers to define dependencies through composer.json and get the code from the source (such as GitHub) at installation time. Its core functions include: 1. Provide centralized package browsing and search; 2. Manage versions to meet dependency constraints; 3. Automatic updates are achieved through webhooks. While custom repositories can be configured to use Composer, Packagist simplifies the distribution process of public packages. The publishing package needs to be submitted to Packagist and set up a webhook, so that others can install it with one click through composerrequire.

To quickly get detailed information about a specific package in Composer, use the composershowvendor/package command. For example, composershowmonolog/monolog, which will display version, description, dependencies and other information; if you are not sure of the name, you can use some names to combine --platform to view platform requirements; add --name-only to simplify output; use -v to display more detailed content; support wildcard search, such as monolog/*.

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.
