+# 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.
