# mini-unassert

a small and fast unassert transform

[![npm][npm-image]][npm-url]

[![travis][travis-image]][travis-url]

[![standard][standard-image]][standard-url]

It transforms `assert` calls to `void` expressions. Use a minifier like [terser](https://github.com/fabiosantoscode/terser) to completely remove them.

Input:

```js

var assert = require('assert')

assert(true)

assert.equal(typeof x, 'string')

assert(sideEffectCall())

assert.throws(function () {})

```

Output:

```js

;

void (true)

void (typeof x, 'string')

void (sideEffectCall())

void (function () {})

```

After minification:

```js

sideEffectCall();

```

## Install

```

npm install mini-unassert

```

## Usage

It works as a stream and as a browserify transform.

```js

var unassert = require('mini-unassert')

fs.createReadStream('file.js')

  .pipe(unassert({ modules: ['assert', 'power-assert', 'nanoassert'] }))

  .pipe(fs.createWriteStream('file.unassert.js'))

```

```js

browserify -g mini-unassert -g uglifyify

```

## API

### `stream = unassert(opts={})`

Create a stream that replaces assert calls with `void` expressions.

* `opts.modules` is an array of assertion module names, defaulting to `['assert']`.

### `b.transform(unassert, opts={})`

Add `unassert` as a browserify transform. `b` is an instance of browserify.

* Set `opts.global` to run it on all files, including dependencies in node_modules. (recommended)

* `opts.modules` is an array of assertion module names, defaulting to `['assert']`.
