rocambole-strip-arbitrary

Strip arbitrary statements (e.g. console) from a rocambole AST

Note

This is based on sindresorhus/rocambole-strip-console and adds more parameters to allow arbitrary statements to be removed with an optional whitelist of properties to keep intact.

This is useful to e.g. strip console or log statements in production builds but keep .warn and .error statements in the code.

Install (from Github, not on NPM yet)

$ npm install --save berstend/rocambole-strip-arbitrary

Usage

var rocambole = require('rocambole');
var stripStatement = require('rocambole-strip-arbitrary');
 
rocambole.moonwalk('if (true) { console.log("foo"); }', function (node) {
    stripStatement(node, 'console', ['warn', 'error']);
}).toString();
//=> if (true) { void 0; }

To prevent any side-effects, console.* is replaced with void 0 instead of being removed. UglifyJS can later remove these void statements.
