Package Exports

  • babel-plugin-minify-simplify

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (babel-plugin-minify-simplify) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

babel-plugin-minify-simplify

Simplifies code for minification by reducing statements into expressions and making expressions uniform where possible.

Example

Reduce statement into expression

In

function foo() {
  if (x) a();
}
function foo2() {
  if (x) a();
  else b();
}

Out

function foo() {
  x && a();
}
function foo2() {
  x ? a() : b();
}

Make expression as uniform as possible for better compressibility

In

undefined
foo['bar']
Number(foo)

Out

void 0
foo.bar
+foo
