# loose-envify
[![Build Status](https://travis-ci.org/zertosh/loose-envify.svg?branch=master)](https://travis-ci.org/zertosh/loose-envify)
Fast (and loose) selective `process.env` replacer using [js-tokens](https://github.com/lydell/js-tokens) instead of an AST. Works just like [envify](https://github.com/hughsk/envify) but much faster.
## Gotchas
* Doesn't handle broken syntax.
* Doesn't look inside embedded expressions in template strings.
- **this won't work:**
```js
console.log(`the current env is ${process.env.NODE_ENV}`);
```
* Doesn't replace oddly-spaced or oddly-commented expressions.
- **this won't work:**
```js
console.log(process./*won't*/env./*work*/NODE_ENV);
```
## Usage/Options
loose-envify has the exact same interface as [envify](https://github.com/hughsk/envify), including the CLI.
## Benchmark
```
envify:
$ for i in {1..5}; do node bench/bench.js 'envify'; done
