Apr 01, 2025 am 07:36 AMStreamline Composer dependencies: Excluding development dependencies in production environment
In PHP project development, Composer is an indispensable dependency management tool. We often list development tools and libraries in the require-dev
section, but in production environments, these libraries are usually redundant. This article will explain how to avoid loading these development dependencies in a production environment, thereby optimizing project size and deployment efficiency.
Problem: Development dependencies are mistakenly entered into production environment
Suppose your composer.json
file contains the following dependencies:
{ "require": { "php": ">=5.6", "baidu/aip-sdk": "^2.2" }, "require-dev": { "dealerdirect/phpcodesniffer-composer-installer": "^0.7.0", "php-parallel-lint/php-parallel-lint": "^1.2.0" } }
dealerdirect/phpcodesniffer-composer-installer
and php-parallel-lint/php-parallel-lint
are only used for code inspection and other work in the development stage, but they are also installed in the vendor
directory, increasing the project size. How to install only the dependencies required by the production environment?
Solution: Accurate installation, optimized loading
To install only production environment dependencies and optimize the autoloader, use the following Composer command:
composer install --no-dev --optimize-autoloader
The --no-dev
option instructs Composer to ignore dependencies in require-dev
and install only dependencies listed in require
section. --optimize-autoloader
option optimizes the automatic loader to improve application loading speed. After executing this command, your vendor
directory will only contain the necessary production dependencies, thereby reducing the project size.

The duration of the airdrop dividend is uncertain, but the LayerZero, StarkNet and ZK ecosystems still have long-term value. 1. LayerZero achieves cross-chain interoperability through lightweight protocols; 2. StarkNet provides efficient and low-cost Ethereum L2 expansion solutions based on ZK-STARKs technology; 3. ZK ecosystem (such as zkSync, Scroll, etc.) expands the application of zero-knowledge proof in scaling and privacy protection; 4. Participation methods include the use of bridging tools, interactive DApps, participating test networks, pledged assets, etc., aiming to experience the next generation of blockchain infrastructure in advance and strive for potential airdrop opportunities.

Ordinary investors can discover potential tokens by tracking "smart money", which are high-profit addresses, and paying attention to their trends can provide leading indicators. 1. Use tools such as Nansen and Arkham Intelligence to analyze the data on the chain to view the buying and holdings of smart money; 2. Use Dune Analytics to obtain community-created dashboards to monitor the flow of funds; 3. Follow platforms such as Lookonchain to obtain real-time intelligence. Recently, Cangming Money is planning to re-polize LRT track, DePIN project, modular ecosystem and RWA protocol. For example, a certain LRT protocol has obtained a large amount of early deposits, a certain DePIN project has been accumulated continuously, a certain game public chain has been supported by the industry treasury, and a certain RWA protocol has attracted institutions to enter.

The coordinated rise of Bitcoin, Chainlink and RWA marks the shift toward institutional narrative dominance in the crypto market. Bitcoin, as a macro hedging asset allocated by institutions, provides a stable foundation for the market; Chainlink has become a key bridge connecting the reality and the digital world through oracle and cross-chain technology; RWA provides a compliance path for traditional capital entry. The three jointly built a complete logical closed loop of institutional entry: 1) allocate BTC to stabilize the balance sheet; 2) expand on-chain asset management through RWA; 3) rely on Chainlink to build underlying infrastructure, indicating that the market has entered a new stage driven by real demand.

Yes, Web3 infrastructure is exploding expectations as demand for AI heats up. Filecoin integrates computing power through the "Compute over Data" plan to support AI data processing and training; Render Network provides distributed GPU computing power to serve AIGC graph rendering; Arweave supports AI model weights and data traceability with permanent storage characteristics; the three are combining technology upgrades and ecological capital promotion, and are moving from the edge to the underlying core of AI.

Dogecoin, Pepe and Brett are leading the meme coin craze. Dogecoin (DOGE) is the originator, firmly ranked first in the market value list, Pepe (PEPE) has achieved hundreds of times increase with its social geek culture, and Brett (BRETT) has become popular with its unique visual style as a new star in Base chain; the three were issued in 2013, 2023 and 2024 respectively. Technically, Dogecoin is based on Litecoin, Pepe and Brett are ERC-20 tokens, and the latter relies on the Base chain to improve efficiency. In terms of community, DOGE Twitter fans have exceeded 3 million, Pepe Reddit is leading in activity, Brett's popularity in Base chain, and DOGE has logged in on the platform.

Crypto market value exceeded US$3 trillion, and funds mainly bet on seven major sectors. 1. Artificial Intelligence (AI) Blockchain: Popular currencies include FET, RNDR, AGIX, Binance and OKX launch related trading pairs and activities, funds bet on AI and decentralized computing power and data integration; 2. Layer2 and modular blockchain: ARB, OP, ZK series, TIA are attracting attention, HTX launches modular assets and provides commission rebates, funds are optimistic about their support for DeFi and GameFi; 3. RWA (real world assets): ONDO, POLYX, XDC and other related assets, OKX adds an RWA zone, and funds are expected to migrate on traditional financial chains; 4. Public chain and platform coins: SOL, BNB, HT, OKB are strong

The most popular tracks for new funds currently include re-staking ecosystems, integration of AI and Crypto, revival of the Bitcoin ecosystem and DePIN. 1) The re-staking protocol represented by EigenLayer improves capital efficiency and absorbs a large amount of long-term capital; 2) The combination of AI and blockchain has spawned decentralized computing power and data projects such as Render, Akash, Fetch.ai, etc.; 3) The Bitcoin ecosystem expands application scenarios through Ordinals, BRC-20 and Runes protocols to activate silent funds; 4) DePIN builds a realistic infrastructure through token incentives to attract the attention of industrial capital.

Yes, the altcoin rebound may indicate that a new bull market has begun, but entry should be cautious. 1. Market sentiment has recovered, and the trading volume of altcoins on platforms such as Binance, Ouyi, and Huobi has surged, and funds have flowed into the AI, Layer2, and GameFi sectors; 2. The counterfeit rebound shows the characteristics of the early bull market, Bitcoin has stabilized, hot spot rotation has accelerated, and new projects have frequently been launched; 3. Whether to enter the market needs to be judged based on investment strategy: long-term investors can gradually build positions in leading projects, short-term traders can pay attention to opportunities in active currency bands, and try new coins in small positions to avoid chasing highs; 4. In the future, we need to observe whether Bitcoin can break through the previous high, the flow of funds on the three major platforms, the Fed's policies and on-chain activity and other key indicators to judge the sustainability of the market.
