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.
