# 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.
