js/css code dependency analyze.
Parse javascript/css code:
const analyze = require('dependency-analyze')
let jsCode = `
import './aaa.scss'
const xxx = require('bbb')
require.resolve('../ccc.js')
`
// result: [
// './aaa.scss',
// 'bbb',
// '../css.js'
// ]
analyze.parseJS(jsCode)
let cssCode = `
@import "aaa.scss", "bbb.scss", 'ccc.scss';
@import "./ddd.scss";
// @import "./eee.scss";
/* @import "./fff.scss" */
`
// result: [
// 'aaa.scss',
// 'bbb.scss',
// 'ccc.scss',
// './ddd.scss'
// ]
analyze.parseCSS(cssCode)
Parse js/css file:
const analyze = require('dependency-analyze')
// result: [
// 'dep1',
// 'dep2',
// ...
// ]
analyze.parse('path/to/some/js/file.js')
Parse a directory:
const analyze = require('dependency-analyze')
// result: {
// 'file.js': [
// 'dep1',
// 'dep2',
// ...
// ],
// 'file.css': [
// 'dep1.css',
// 'dep2.css',
// ...
// ],
// ...
// }
analyze.parse('path/to/some/dir')
analyze dependencies from content recursively.
const analyze = require('dependency-analyze')
// result: {
// '/path/to/mock/file.js', {
// deps: [{
// parent: '/path/to/mock/file.js',
// raw: 'react',
// name: 'react',
// module: 'react',
// file: null
// }, {
// parent: '/path/to/mock/file.js',
// raw: 'react-dom',
// name: 'react-dom',
// module: 'react-dom',
// file: null
// }, {
// parent: '/path/to/mock/file.js',
// raw: './src/index.jsx',
// name: './src/index.jsx',
// module: null,
// file: '/path/to/mock/src/index.jsx'
// }],
// modules: [
// 'react',
// 'react-dom'
// ],
// relatives: [
// '/path/to/mock/src/index.jsx'
// ],
// },
// '/path/to/mock/src/index.jsx': {
// deps: [ ... ],
// modules: [ ... ],
// relatives: [ ... ]
// },
// ...
// }
analyze.analyze({
file: '/path/to/mock/entry.js',
content: `
import React from "react";
import ReactDOM from "react-dom";
import "./src/index.jsx";
`
})
// or your can pass file (if file exists)
analyze.analyze('/path/to/real/entry.js')
// or multiple entries
// or your can pass file (if file exists)
analyze.analyze([
'/path/to/real/entry1.js',
'/path/to/real/entry2.js'
])
analyze.parseJS(content)
Parse js code and get it's dependencies.
content {String}
js code{Array}
an dependencies arrayanalyze.parseCSS(content)
Parse css (sass/less) code and get it's dependencies.
content {String}
css (sass/less) code{Array}
an dependencies arrayanalyze.parse(file[, matches])
Parse a file/directory, and get it's dependencies.
file {String}
file or dir pathmatches {String|Array}
minimatch rules (String
will be treat as a single rule)If matches
is specfied, the files under basedir (file
) will be filtered; otherwise all files except dot-started file (.xxx
, *nix hidden file) will be parsed.
{Array}
if file
is a File, then dependencies array will be return
{Object}
if file
is a directory, then a (file => dependencies) Object will be return, just like:
return {
'dir/index.js': [
'dep1',
'dep2',
...
],
'dir/index.css': [
'dep1',
'dep2',
...
]
}
analyze.analyze(entry[, options])
analyze dependencies of specified entry (eg. file path, file content, multiple files) recursively.
entry {Mixed}
type of entry
can be String
(file path) or Object
(file + content info), or multiple entries
{String}
the file path{Object}
the object of file and content { file: ..., content: ... }
{Array}
the array of file or file/content objectoptions {Object}
analyze options
{Number}
max recursive resolve depth (default is Infinity){Function}
custom resolve dep to standard format (e.g. ~xxx
=> xxx
){Function}
filter which deps can be resolved, will be invoked with (dep, currFile)
options.depResolve
will be invoked with params (dep, currFile, defaultResolve)
:
dep {String}
original dep stringcurrFile {String}
current file to resolvedefaultResolve {Function}
default dep resolve functionwill return a object like:
{
'/path/to/entry.js': {
deps: [{
parent: '/path/to/entry.js',
raw: 'react',
name: 'react',
module: 'react',
file: null,
}, ...],
modules: [
'react',
...
],
relatives: [
'/path/to/a.js',
...
]
}
}
dependency-analyze use different parser to parse code.
Use babylon to parse js code, these statements will be considered as a dependency:
import 'xxx'
require('xxx')
require.resolve('xxx')
Use RegExp to parse css code, @import
statement will be considered as a dependency.
Don't worry about @import
in css comments, they will be skipped
