Precinct
Unleash the detectives
npm install --save precinct
Uses the appropriate detective to find the dependencies of a file or its AST.
Supports:
- JavaScript modules: AMD, CommonJS, and ES6.
- Typescript
- CSS Preprocessors: Sass, Stylus, and Less
- CSS (PostCSS)
Usage
var precinct = require('precinct');
var content = fs.readFileSync('myFile.js', 'utf8');
// Pass in a file's content or an AST
var deps = precinct(content);
You may pass options (to individual detectives) based on the module type via an optional second object argument `detective(content, options), for example:
Example call: precinct(content, { amd: { skipLazyLoaded: true } });
- The supported module type prefixes are
amd
,commonjs
,css
,es6
,less
,sass
,scss
,stylus
,ts
,tsx
Current options:
amd.skipLazyLoaded
: tells the AMD detective to omit lazy-loaded dependencies (i.e., inner requires).es6.mixedImports
: allows for all dependencies to be fetched from a file that contains both CJS and ES6 imports.
- Note: This will work for any file format that contains an es6 import.
css.url
: tells the CSS detective to includeurl()
references to images, fonts, etc.
Finding non-JavaScript (ex: Sass and Stylus) dependencies:
var content = fs.readFileSync('styles.scss', 'utf8');
var deps = precinct(content, { type: 'sass' });
var deps2 = precinct(content, { type: 'stylus' });
Or, if you just want to pass in a filepath and get the dependencies:
var paperwork = require('precinct').paperwork;
var deps = paperwork('myFile.js');
var deps2 = paperwork('styles.scss');
precinct.paperwork(filename, options)
Supported options:
includeCore
: (default: true) set tofalse
to exclude core Node dependencies from the list of dependencies.fileSystem
: (default: undefined) set to an alternativefs
implementation that will be used to read the file path.- You may also pass detective-specific configuration like you would to
precinct(content, options)
.
CLI
