## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 4872, "days_push": 1367, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A collection of front-end coding specifications from Baidu's EFE team, covering JavaScript, HTML, CSS, Less, React, JSON data transfer, module loading, package and directory structure standards. It is primarily a set of written style guides rather than executable software, with the companion FECS tool providing automated linting.

## Use cases
- standardize JavaScript coding style across a team
- define HTML and CSS conventions for a project
- set up project directory and package structure guidelines
- adopt a JSON data transfer standard for APIs
- review React code against a written style guide
- find a linting tool that enforces these specs

## When to choose
- you want a battle-tested, opinionated set of front-end coding standards
- your team reads Chinese and wants detailed style guides
- you need conventions for module loading and package structure in legacy JS projects

## When to avoid
- you need executable linting only - use FECS or ESLint directly
- you require English-language documentation
- you need actively updated standards for modern frameworks beyond the draft React guide

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, linter
- domain: web-development, frontend, developer-tools, documentation
- platform: cross-platform
- tags: style-guide, coding-standards, javascript, html, css, less, react, chinese
