# Browserify
XXX explain
As the [Browserify](http://browserify.org/) site says it "lets you
`require('modules')` in the browser by bundling up all of your dependencies."
It is a build tool to run on your node.js script to bundle up your script and
all its node.js dependencies into a single file that is runnable in the
browser via:
<script src="foo.browser.js"></script>
<script src="play.browser.js"></script>
As of version 1.1.0, node-bunyan supports being run via Browserify. The
default [stream](#streams) when running in the browser is one that emits

For some the raw log records might not be desired, to have a rendered log line
For some, the raw log records might not be desired. To have a rendered log line
you'll want to add your own stream, starting with something like this:
function MyRawStream() {}
MyRawStream.prototype.write = function (rec) {
var nameFromLevel = {
TRACE: 'TRACE'
DEBUG: 'DEBUG',
INFO: 'INFO',
WARN: 'WARN',
ERROR: 'ERROR',
FATAL: 'FATAL'
};
console.log('[%s] %s: %s', rec.time, nameFromLevel[rec.level], rec.msg);
}
```javascript
function MyRawStream() {}
MyRawStream.prototype.write = function (rec) {
var nameFromLevel = {
TRACE: 'TRACE'
DEBUG: 'DEBUG',
INFO: 'INFO',
WARN: 'WARN',
ERROR: 'ERROR',
FATAL: 'FATAL'
};
console.log('[%s] %s: %s', rec.time, nameFromLevel[rec.level], rec.msg);
}
var log = bunyan.createLogger({
name: 'foo',
streams: [
{
level: 'info',
stream: new MyRawStream(),
type: 'raw'
},
]
});
var log = bunyan.createLogger({
name: 'play',
streams: [
{
level: 'info',
stream: new MyRawStream(),

log.info('hi on info');
log.info('hi on info');
