In addition to +those listed below, [zlib](https://nodejs.org/api/zlib.html) options may be +passed in to the options object or +[brotli](https://nodejs.org/api/zlib.html#zlib_class_brotlioptions) options. + +##### chunkSize + +Type: `Number`
+Default: `zlib.constants.Z_DEFAULT_CHUNK`, or `16384`. + +See [Node.js documentation](https://nodejs.org/api/zlib.html#zlib_memory_usage_tuning) +regarding the usage. + +##### filter + +Type: `Function` + +A function to decide if the response should be considered for compression. +This function is called as `filter(req, res)` and is expected to return +`true` to consider the response for compression, or `false` to not compress +the response. + +The default filter function uses the [compressible](https://www.npmjs.com/package/compressible) +module to determine if `res.getHeader('Content-Type')` is compressible. + +##### level + +Type: `Number`
+Default: `zlib.constants.Z_DEFAULT_COMPRESSION`, or `-1` + +The level of zlib compression to apply to responses. A higher level will result +in better compression, but will take longer to complete. A lower level will +result in less compression, but will be much faster. + +This is an integer in the range of `0` (no compression) to `9` (maximum +compression). The special value `-1` can be used to mean the "default +compression level", which is a default compromise between speed and +compression (currently equivalent to level 6). + + - `-1` Default compression level (also `zlib.constants.Z_DEFAULT_COMPRESSION`). + - `0` No compression (also `zlib.constants.Z_NO_COMPRESSION`). + - `1` Fastest compression (also `zlib.constants.Z_BEST_SPEED`). + - `2` + - `3` + - `4` + - `5` + - `6` (currently what `zlib.constants.Z_DEFAULT_COMPRESSION` points to). + - `7` + - `8` + - `9` Best compression (also `zlib.constants.Z_BEST_COMPRESSION`). + +**Note** in the list above, `zlib` is from `zlib = require('zlib')`. + +##### memLevel + +Type: `Number`
+Default: `zlib.constants.Z_DEFAULT_MEMLEVEL`, or `8` + +This specifies how much memory should be allocated for the internal compression +state and is an integer in the range of `1` (minimum level) and `9` (maximum +level). + +See [Node.js documentation](https://nodejs.org/api/zlib.html#zlib_memory_usage_tuning) +regarding the usage. + +##### brotli + +Type: `Object` + +This specifies the options for configuring Brotli. See [Node.js documentation](https://nodejs.org/api/zlib.html#class-brotlioptions) for a complete list of available options. + + +##### strategy + +Type: `Number`
+Default: `zlib.constants.Z_DEFAULT_STRATEGY` + +This is used to tune the compression algorithm. This value only affects the +compression ratio, not the correctness of the compressed output, even if it +is not set appropriately. + + - `zlib.constants.Z_DEFAULT_STRATEGY` Use for normal data. + - `zlib.constants.Z_FILTERED` Use for data produced by a filter (or predictor). + Filtered data consists mostly of small values with a somewhat random + distribution. In this case, the compression algorithm is tuned to + compress them better. The effect is to force more Huffman coding and less + string matching; it is somewhat intermediate between `zlib.constants.Z_DEFAULT_STRATEGY` + and `zlib.constants.Z_HUFFMAN_ONLY`. + - `zlib.constants.Z_FIXED` Use to prevent the use of dynamic Huffman codes, allowing + for a simpler decoder for special applications. + - `zlib.constants.Z_HUFFMAN_ONLY` Use to force Huffman encoding only (no string match). + - `zlib.constants.Z_RLE` Use to limit match distances to one (run-length encoding). + This is designed to be almost as fast as `zlib.constants.Z_HUFFMAN_ONLY`, but give + better compression for PNG image data. + +**Note** in the list above, `zlib` is from `zlib = require('zlib')`. + +##### threshold + +Type: `Number` or `String`
+Default: `1kb` + +The byte threshold for the response body size before compression is considered +for the response. This is a number of bytes or any string +accepted by the [bytes](https://www.npmjs.com/package/bytes) module. + +**Note** this is only an advisory setting; if the response size cannot be determined +at the time the response headers are written, then it is assumed the response is +_over_ the threshold. To guarantee the response size can be determined, be sure +set a `Content-Length` response header. + +##### windowBits + +Type: `Number`
+Default: `zlib.constants.Z_DEFAULT_WINDOWBITS`, or `15` + +See [Node.js documentation](https://nodejs.org/api/zlib.html#zlib_memory_usage_tuning) +regarding the usage. + +##### enforceEncoding + +Type: `String`
+Default: `identity` + +This is the default encoding to use when the client does not specify an encoding in the request's [Accept-Encoding](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Accept-Encoding) header. + +#### .filter + +The default `filter` function. This is used to construct a custom filter +function that is an extension of the default function. + +```js +var compression = require('compression') +var express = require('express') + +var app = express() + +app.use(compression({ filter: shouldCompress })) + +function shouldCompress (req, res) { + if (req.headers['x-no-compression']) { + // don't compress responses with this request header + return false + } + + // fallback to standard filter function + return compression.filter(req, res) +} +``` + +### res.flush + +This module adds a `res.flush()` method to force the partially-compressed +response to be flushed to the client. + +## Examples + +### express + +When using this module with express, simply `app.use` the module as +high as you like. Requests that pass through the middleware will be compressed. + +```js +var compression = require('compression') +var express = require('express') + +var app = express() + +// compress all responses +app.use(compression()) + +// add all routes +``` + +### Node.js HTTP server + +```js +var compression = require('compression')({ threshold: 0 }) +var http = require('http') + +function createServer (fn) { + return http.createServer(function (req, res) { + compression(req, res, function (err) { + if (err) { + res.statusCode = err.status || 500 + res.end(err.message) + return + } + + fn(req, res) + }) + }) +} + +var server = createServer(function (req, res) { + res.setHeader('Content-Type', 'text/plain') + res.end('hello world!') +}) + +server.listen(3000, () => { + console.log('> Listening at http://localhost:3000') +}) +``` + +### Server-Sent Events + +Because of the nature of compression this module does not work out of the box +with server-sent events. To compress content, a window of the output needs to +be buffered up in order to get good compression. Typically when using server-sent +events, there are certain block of data that need to reach the client. + +You can achieve this by calling `res.flush()` when you need the data written to +actually make it to the client. + +```js +var compression = require('compression') +var express = require('express') + +var app = express() + +// compress responses +app.use(compression()) + +// server-sent event stream +app.get('/events', function (req, res) { + res.setHeader('Content-Type', 'text/event-stream') + res.setHeader('Cache-Control', 'no-cache') + + // send a ping approx every 2 seconds + var timer = setInterval(function () { + res.write('data: ping\n\n') + + // !!! this is the important part + res.flush() + }, 2000) + + res.on('close', function () { + clearInterval(timer) + }) +}) +``` + +## Contributing + +The Express.js project welcomes all constructive contributions.

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:". + +## Environment Variables + + When running through Node.js, you can set a few environment variables that will + change the behavior of the debug logging: + +| Name | Purpose | +|-----------|-------------------------------------------------| +| `DEBUG` | Enables/disables specific debugging namespaces. | +| `DEBUG_COLORS`| Whether or not to use colors in the debug output. | +| `DEBUG_DEPTH` | Object inspection depth. | +| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. | + + + __Note:__ The environment variables beginning with `DEBUG_` end up being + converted into an Options object that gets used with `%o`/`%O` formatters. + See the Node.js documentation for + [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options) + for the complete list. + +## Formatters + + + Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters: + +| Formatter | Representation | +|-----------|----------------| +| `%O` | Pretty-print an Object on multiple lines. | +| `%o` | Pretty-print an Object all on a single line. | +| `%s` | String. | +| `%d` | Number (both integer and float). | +| `%j` | JSON. Replaced with the string '[Circular]' if the argument contains circular references. | +| `%%` | Single percent sign ('%'). This does not consume an argument. | + +### Custom formatters + + You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like: + +```js +const createDebug = require('debug') +createDebug.formatters.h = (v) => { + return v.toString('hex') +} + +// …elsewhere +const debug = createDebug('foo') +debug('this is hex: %h', new Buffer('hello world')) +// foo this is hex: 68656c6c6f20776f726c6421 +0ms +``` + +## Browser support + You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify), + or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest), + if you don't want to build it yourself. + + Debug's enable state is currently persisted by `localStorage`. + Consider the situation shown below where you have `worker:a` and `worker:b`, + and wish to debug both. You can enable this using `localStorage.debug`: + +```js +localStorage.debug = 'worker:*' +``` + +And then refresh the page. + +```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) + + +## Output streams + + By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method: + +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'); +``` + + +## Authors + + - TJ Holowaychuk + - Nathan Rajlich + - Andrew Rhyne + +## Backers + +Support us with a monthly donation and help us continue our activities.
