# 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
|
|
```
