HOW

ゴール: Parse multi-environment configuration sections, load environment configurations, and query Node.js versions with browserslist
パッケージ: browserslist 4.28.8
シンボル: browserslist.findConfig
browserslist.loadConfig
browserslist.nodeVersions
browserslist.parseConfig
環境: node 22.23.2
作成日: 2026-08-24T20:19:22Z

browserslist.parseConfig(configString) parses multi-environment config text into section maps, stripping comments and empty lines
browserslist.parseConfig('') on empty or comment-only string returns an object with an empty defaults array
browserslist.findConfig(dir) discovers .browserslistrc files and returns structured section mappings
browserslist.findConfig(dir) discovers package.json browserslist array configurations and wraps them under defaults
browserslist.findConfig(dir) returns undefined when no configuration file exists in the directory tree
browserslist.loadConfig({ path, env }) selects queries for the specified environment, defaulting to production
browserslist.loadConfig({ path, env }) falls back to the defaults section when an unknown environment is requested
browserslist(null, { path, env }) resolves target browsers directly from discovered configuration files
browserslist.nodeVersions exposes an array of all known Node.js release versions used for node query resolution
