UnassertPlugin

A fuse-box plugin for unassert: Encourages programming with assertions by providing tools to compile them away.

Description

UnassertPlugin is a fuse-box plugin to remove assertions on production builds.

See unassert project for more documentation.

Installation

Install fusebox-unassert-plugin via npm:

$ npm install --save-dev fusebox-unassert-plugin

Usage

Setup

Import plugin

const { UnassertPlugin } = require("fusebox-unassert-plugin");

Inject into a chain

fuse.bundle("app").plugin(UnassertPlugin());

Or add it to the main config plugins list to make it available across bundles.

FuseBox.init({
  plugins: [UnassertPlugin()],
});

The plugin will parse source files (.js, .jsx, .ts, .tsx) into syntax trees by using esprima, and then re-generate JavaScript using escodegen. It is primarily intended for Quantum and uglified builds since the output will not have identical formatting to the input.

FuseBox.init({
  plugins: [
    ...
    this.isProduction && UnassertPlugin(),
    this.isProduction && QuantumPlugin({ uglify:true })
  ],
});

Options

You can pass unassert options, if not passed, default options (Same as unassert.defaultOptions()) will be used.
