# stream-via
Process each chunk of a stream via the supplied function. Useful for meddling inside a stream pipeline. Works in both string/Buffer and object modes.

## Synopsis

Replace all instances of the `a` character with `4`.

```js
const via = require('stream-via')
const fs = require('fs')

process.stdin
  .pipe(via(function (chunk) {
    return chunk.toString().replace(/a/g, '4')
  }))
  .pipe(process.stdout)
```

Output:
```
$ echo 'twat' | node example/simple.js
tw4t
```
