babel-plugin-minify-flip-comparisons

Note: while this plugin doesn’t shorten the output in any way, it does optimize it for repetition-based compression algorithms such as gzip.

Example

const foo = a === 1;
if (bar !== null) {
  var baz = 0;
}

Out

const foo = 1 === a;
if (null !== bar) {
  var baz = 0;
}

npm install babel-plugin-minify-flip-comparisons --save-dev

  "plugins": ["minify-flip-comparisons"]
}

babel --plugins minify-flip-comparisons script.js

require("@babel/core").transform("code", {
  plugins: ["minify-flip-comparisons"]
});
