Readme

limit-spawn

Description

Kills a child process created with spawn after X bytes are sent and emits an event.

Installation

```bash npm install limit-spawn ```

Note

This is a soft limit, meaning that after more than MAX data is received the process is closed and the 'max-limit-exceeded' is emitted. So this implies that you can receive more data than the limit (depending on the last chunk).

Examples

```js var spawn = require('childprocess').spawn,
limit  = require('../index'),
assert = require('assert'),
child, ps, bytesReceived, MAX_LIMIT;
MAX
LIMIT = 100 1024; // 100 Kb child = spawn('node', 'forever-output.js', { cwd: dirname }); limit(child, MAXLIMIT); bytesReceived = 0; child.stdout.on('data', function(data) { bytesReceived += data.length; }); child.stderr.pipe(process.stderr); child.on('max-limit-exceeded', function(size) { console.log('limit exceeded: ' + parseInt(size / 1024, 10) + ' Kb sent'); }); // shortly after the 'max-limit-exceeded' event is emitted the child dies child.on('close', function(code) { console.log('child process exited'); }); ```

Tests

```bash npm test ```
