API

strip

Params

• input {String}: string from which to strip comments
• options {Object}: optional options, passed to extract-comments

• line {Boolean}: if false strip only block comments, default true
• block {Boolean}: if false strip only line comments, default true
• keepProtected {Boolean}: Keep ignored comments (e.g. /*! and //!)
• preserveNewlines {Boolean}: Preserve newlines after comments are stripped

• returns {String}: modified input

console.log(str);
// => 'const foo = "bar";'

.block

Strip only block comments.

Params

• input {String}: string from which to strip comments
• options {Object}: pass opts.keepProtected: true to keep ignored comments (e.g. /*!)
• returns {String}: modified string

Example

const strip = require('..');
const str = strip.block('const foo = "bar";// this is a comment\n /* me too */');
console.log(str);
// => 'const foo = "bar";// this is a comment'

.line
