Detect if a javascript file is uglified

How?

We use Mean Identify Length measure. For one handwriting javascript file, the average length of identifiers MUST bigger than it of an uglified one.

E.g.,

• The mean identify length of react.development.js is 10.8
• The mean identify length of the minimized version react.production.js is 1.7, which is much more smaller than before.

We set the threshold value default to 3, detecting whether a javascript file is uglified.

Installing

npm install is-uglified

Usage

import isUglified from 'is-uglified';

isUglified('local_file_to_detect.js') // get result;
