babel-plugin-class-display-name

After the creation of each class, the plugin manually sets the prototype.name to the class name. This means that after minification class errors still have the correct name.

Installation

$ npm install --dev @triptease/babel-plugin-transform-class-prototype-name

Usage

Via .babelrc (Recommended)

.babelrc

{
  "plugins": ["@triptease/babel-plugin-transform-class-prototype-name"]
}

Compilation

In

class CustomError extends Error {}

Out

class CustomError extends Error {}
CustomError.prototype.name = "CustomError";

After minification

class a extends Error {}
a.prototype.name = "CustomError";
