Front‑End Development Standards and Best Practices

In this article the author, a front‑end specialist, introduces a systematic approach to front‑end development standards, starting with a realistic code‑review scenario and a sample function that can be optimized.

// 点击定位按钮，获取县市地址方法 const clickDw = function(type) { let dz // 地址列表 let dzTable = ['北京市'，'上海市', '广州市', '深圳市'] if(type === 1 || type === 2 || type === 3) { // do something return dz } else if(type === 4 || type === 5) { // do something return dz } else { // default return dz } }

The article then lists common team problems such as legacy code debt, pressure for speed over quality, lack of GitFlow, missing documentation, and communication gaps, explaining how these issues affect overall efficiency.

It defines a "standard" as any practice that improves maintainability, reduces understanding cost, lowers fault tolerance, and enhances scalability.

Benefits of adopting standards include consistent code, reduced development cost, higher team efficiency, lower communication overhead, personal growth, and better code‑review outcomes.

Front‑end naming conventions are covered with examples of bad and good practices. Sample file‑path naming:

usr/dev/document/front-end/project-vue3

Variable and function naming rules are illustrated with concise functions:

// 更新数据 function updateData(){ return {}; } // 获取用户信息 function getUserInfo{ return {} }

CSS naming guidelines are shown:

.heavy { font-weight: 800; } .important { color: red; }

The guide also discusses technology‑stack decisions (TypeScript vs JavaScript, Vue vs React, Less vs Sass, Vite vs Webpack) and explains the rationale behind the author’s choices.

Programming standards emphasize unified coding rules, automated tools (ESLint, Prettier, Stylelint) and provide a detailed Git workflow, focusing on feature‑branch flow and a strict commit message format:

<type>(<scope>): <subject> // 注意冒号 : 后有空格 // 如 feat(user): 增加用户中心的 xx 功能

Git commit types (feat, bug, fix, ui, docs, style, refactor, perf, release, deploy, test, chore, revert, build) are enumerated.

Further sections cover BFF design principles, front‑back collaboration processes, IDE configuration standards, testing categories (unit, integration, UI) with tool recommendations (Mocha, Jest, Vitest), browser compatibility considerations, and the importance of comprehensive documentation.

Finally, the article stresses the role of Code Review, providing guidelines for effective reviews, communication tone, and integration with automation tools, concluding that a well‑defined front‑end standardization effort boosts code quality, team harmony, and project success.
