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, es6, sass, stylus, less

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 include url() 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 to false to exclude core Node dependencies from the list of dependencies.
• fileSystem: (default: undefined) set to an alternative fs 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

Assumes a global install of npm install -g precinct

precinct [options] path/to/file
