# debug |
|||
|
|||
tiny node.js debugging utility modelled after node core's debugging technique. |
|||
|
|||
## Installation |
|||
|
|||
```bash |
|||
$ npm install debug |
|||
``` |
|||
|
|||
## Usage |
|||
|
|||
With `debug` you simply invoke the exported function to generate your debug function, passing it a name which will determine if a noop function is returned, or a decorated `console.error`, so all of the `console` format string goodies you're used to work fine. A unique color is selected per-function for visibility. |
|||
|
|||
Example _app.js_: |
|||
|
|||
```js |
|||
var debug = require('debug')('http') |
|||
, http = require('http') |
|||
, name = 'My App'; |
|||
|
|||
// fake app |
|||
|
|||
debug('booting %s', name); |
|||
|
|||
http.createServer(function(req, res){ |
|||
debug(req.method + ' ' + req.url); |
|||
res.end('hello\n'); |
|||
}).listen(3000, function(){ |
|||
debug('listening'); |
|||
}); |
|||
|
|||
// fake worker of some kind |
|||
|
|||
require('./worker'); |
|||
``` |
|||
|
|||
Example _worker.js_: |
|||
|
|||
```js |
|||
var debug = require('debug')('worker'); |
|||
|
|||
setInterval(function(){ |
|||
debug('doing some work'); |
|||
}, 1000); |
|||
``` |
|||
|
|||
The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples: |
|||
|
|||
![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png) |
|||
|
|||
![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png) |
|||
|
|||
#### Windows note |
|||
|
|||
On Windows the environment variable is set using the `set` command. |
|||
|
|||
```cmd |
|||
set DEBUG=*,-not_this |
|||
``` |
|||
|
|||
Then, run the program to be debugged as usual. |
|||
|
|||
## Millisecond diff |
|||
|
|||
When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls. |
|||
|
|||
![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png) |
|||
|
|||
When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below: |
|||
|
|||
![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png) |
|||
|
|||
## Conventions |
|||
|
|||
If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser". |
|||
|
|||
## Wildcards |
|||
|
|||
The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`. |
|||
|
|||
You can also exclude specific debuggers by prefixing them with a "-" character. For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:". |
|||
|
|||
## Browser support |
|||
|
|||
Debug works in the browser as well, currently persisted by `localStorage`. Consider the situation shown below where you have `worker:a` and `worker:b`, and wish to debug both. Somewhere in the code on your page, include: |
|||
|
|||
```js |
|||
window.myDebug = require("debug"); |
|||
``` |
|||
|
|||
("debug" is a global object in the browser so we give this object a different name.) When your page is open in the browser, type the following in the console: |
|||
|
|||
```js |
|||
myDebug.enable("worker:*") |
|||
``` |
|||
|
|||
Refresh the page. Debug output will continue to be sent to the console until it is disabled by typing `myDebug.disable()` in the console. |
|||
|
|||
```js |
|||
a = debug('worker:a'); |
|||
b = debug('worker:b'); |
|||
|
|||
setInterval(function(){ |
|||
a('doing some work'); |
|||
}, 1000); |
|||
|
|||
setInterval(function(){ |
|||
b('doing some work'); |
|||
}, 1200); |
|||
``` |
|||
|
|||
#### Web Inspector Colors |
|||
|
|||
Colors are also enabled on "Web Inspectors" that understand the `%c` formatting |
|||
option. These are WebKit web inspectors, Firefox ([since version |
|||
31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/)) |
|||
and the Firebug plugin for Firefox (any version). |
|||
|
|||
Colored output looks something like: |
|||
|
|||
![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png) |
|||
|
|||
### stderr vs stdout |
|||
|
|||
You can set an alternative logging method per-namespace by overriding the `log` method on a per-namespace or globally: |
|||
|
|||
Example _stdout.js_: |
|||
|
|||
```js |
|||
var debug = require('debug'); |
|||
var error = debug('app:error'); |
|||
|
|||
// by default stderr is used |
|||
error('goes to stderr!'); |
|||
|
|||
var log = debug('app:log'); |
|||
// set this namespace to log via console.log |
|||
log.log = console.log.bind(console); // don't forget to bind to console! |
|||
log('goes to stdout'); |
|||
error('still goes to stderr!'); |
|||
|
|||
// set all output to go via console.info |
|||
// overrides all per-namespace log settings |
|||
debug.log = console.info.bind(console); |
|||
error('now goes to stdout via console.info'); |
|||
log('still goes to stdout, but via console.info now'); |
|||
``` |
|||
|
|||
### Save debug output to a file |
|||
|
|||
You can save all debug statements to a file by piping them. |
|||
|
|||
Example: |
|||
|
|||
```bash |
|||
$ DEBUG_FD=3 node your-app.js 3> whatever.log |
|||
``` |
