如何查看一个 js, ts 文件模块的依赖树最近接手一个别人的页面，代码很是凌乱与庞杂，当我在增加功能时，发现我添加的模块与原有的模块有冲突，但不知道那个原有的模块在什么位置，就得到处找。但发现这种方式太笨拙了，网上也没有找到相应的工具，索性我就自己写了一个工具。项目地址：sdep。安装npm install sdep -g使用sdep [options] <file>常用命令行参数-q, –query <query>: 查找某个模块的依赖链（如：-q react）-r, –regular: 把 query 当作正则来匹配（如：-q ‘react|react-dom’ -r）-i, –ignore: 不显示 node_modules 里的文件使用的第三方库commander.jsnode-dependency-tree例子查看一个文件的依赖结构sdep example/index.jsexample/index.js├ example/css/css.css├ example/css/scss.scss├ example/css/less.less├ example/jsx.jsx| ├ node_modules/react/index.js| | ├ node_modules/react/cjs/react.production.min.js| | | └ node_modules/object-assign/index.js| | └ node_modules/react/cjs/react.development.js| | ├ node_modules/object-assign/index.js| | └ node_modules/prop-types/checkPropTypes.js| | └ node_modules/prop-types/lib/ReactPropTypesSecret.js| ├ node_modules/react-dom/index.js| | ├ node_modules/react-dom/cjs/react-dom.production.min.js| | | ├ node_modules/react/index.js| | | | ├ node_modules/react/cjs/react.production.min.js| | | | | └ node_modules/object-assign/index.js| | | | └ node_modules/react/cjs/react.development.js| | | | ├ node_modules/object-assign/index.js| | | | └ node_modules/prop-types/checkPropTypes.js| | | | └ node_modules/prop-types/lib/ReactPropTypesSecret.js| | | ├ node_modules/object-assign/index.js| | | └ node_modules/scheduler/index.js| | | ├ node_modules/scheduler/cjs/scheduler.production.min.js| | | └ node_modules/scheduler/cjs/scheduler.development.js| | └ node_modules/react-dom/cjs/react-dom.development.js| | ├ node_modules/react/index.js| | | ├ node_modules/react/cjs/react.production.min.js| | | | └ node_modules/object-assign/index.js| | | └ node_modules/react/cjs/react.development.js| | | ├ node_modules/object-assign/index.js| | | └ node_modules/prop-types/checkPropTypes.js| | | └ node_modules/prop-types/lib/ReactPropTypesSecret.js| | ├ node_modules/object-assign/index.js| | ├ node_modules/prop-types/checkPropTypes.js| | | └ node_modules/prop-types/lib/ReactPropTypesSecret.js| | ├ node_modules/scheduler/index.js| | | ├ node_modules/scheduler/cjs/scheduler.production.min.js| | | └ node_modules/scheduler/cjs/scheduler.development.js| | └ node_modules/scheduler/tracing.js| | ├ node_modules/scheduler/cjs/scheduler-tracing.production.min.js| | └ node_modules/scheduler/cjs/scheduler-tracing.development.js| └ example/wel.jsx| └ node_modules/react/index.js| ├ node_modules/react/cjs/react.production.min.js| | └ node_modules/object-assign/index.js| └ node_modules/react/cjs/react.development.js| ├ node_modules/object-assign/index.js| └ node_modules/prop-types/checkPropTypes.js| └ node_modules/prop-types/lib/ReactPropTypesSecret.js└ example/async/index.js └ example/async/index.css查看一个文件包含 react 的依赖链sdep example/index.js -q reactexample/index.js└ example/jsx.jsx └ node_modules/react/index.jsexample/index.js└ example/jsx.jsx └ node_modules/react-dom/index.jsexample/index.js└ example/jsx.jsx └ example/wel.jsx └ node_modules/react/index.js查看一个文件包含 less 或 scss 的依赖链sdep example/index.js -q ’less|scss’ -rexample/index.js└ example/css/scss.scssexample/index.js└ example/css/less.less后续更多博客，查看 https://github.com/senntyou/blogs作者：深予之 (@senntyou)版权声明：自由转载-非商用-非衍生-保持署名（创意共享3.0许可证）
