+# meterstream
+
+[![Build Status](https://travis-ci.org/blockai/meterstream.svg?branch=master)](https://travis-ci.org/blockai/meterstream)
+
+Transform stream that emits a `MeterStream.OverflowError` error if it has
+read more than `maxBytes` bytes.
+
+Note: if more than `maxBytes` is read, the transform will ensure that
+exactly `maxBytes` have been flushed to the readable side before
+emitting the OverflowError.
+
+## Install
+
+```bash
+npm install --save meterstream
+```
+
+Requires Node v6+
+
+## Usage
+
+**new MeterStream(maxBytes = Infinity)**
+
+Returns a pass through stream where `maxBytes` (defaults to `Infinity`)
+is the max number of bytes to pass through before emitting an error.
+
+See [./test](./test) directory for usage examples.
+
+```javascript
+import MeterStream from 'meterstream'
+
+process.stdin
+  .pipe(new MeterStream(5))
+  .on('error', (err) => {
+    console.error('Read more than 5 bytes from stdin')
+    console.error(err)
+    process.exit(1)
+  })
+  .pipe(process.stdout)
+
+
+// echo -n "123456789" | babel-node src/demo.js
+// 12345Read more than 5 bytes from stdin
+// Error: Stream exceeded specified max of 5 bytes.
+//     at OverflowError (...)
+//     at ....
