detective

find all calls to require() by walking the AST


example

strings

strings_src.js:

`` js
var a = require('a');
var b = require('b');
var c = require('c');
`

strings.js:

` js
var detective = require('detective');
var fs = require('fs');

var src = fs.readFileSync(__dirname + '/strings_src.js');
var requires = detective(src);
console.dir(requires);
`

output:

`
$ node examples/strings.js
[ 'a', 'b', 'c' ]
`

methods

` js
var detective = require('detective');
`

detective(src, opts)

Give some source body src, return an array of all the require() calls with
string arguments.

The options parameter opts is passed along to detective.find().

var found = detective.find(src, opts)

Give some source body src, return found with:

* found.strings - an array of each string found in a require()
* found.expressions - an array of each stringified expression found in a
require() call
* found.nodes (when opts.nodes === true) - an array of AST nodes for each
argument found in a require() call

Optionally:

* opts.word - specify a different function name instead of "require"
* opts.nodes - when true, populate found.nodes
* opts.isRequire(node) - a function returning whether an AST CallExpression
node is a require call
* opts.parse - supply options directly to
acorn with some support for esprima-style
options range and loc
* opts.ecmaVersion - default: 9

install

With npm do:

`
npm install detective
``
