extract-banner

Extract a banner comment from a string of javascript.

Install

Install with npm:

$ npm install extract-banner --save

Usage

Works for block and line comments.

var extract = require('extract-banner');

Heads up!: banner comments may be preceded by only whitespace and/or "use strict"; statements. Aside from those exceptions a banner comment must be the first thing in a string.

Example

var fs = require('fs');
var extract = require('extract-banner');
var str = fs.readFileSync('fixtures/banner.js', 'utf8');
var banner = extract(str);
