In addition to +those listed below, [zlib](http://nodejs.org/api/zlib.html) options may be +passed in to the options object. + +##### chunkSize + +The default value is `zlib.Z_DEFAULT_CHUNK`, or `16384`. + +See [Node.js documentation](http://nodejs.org/api/zlib.html#zlib_memory_usage_tuning) +regarding the usage. + +##### filter + +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 + +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.Z_DEFAULT_COMPRESSION`). + - `0` No compression (also `zlib.Z_NO_COMPRESSION`). + - `1` Fastest compression (also `zlib.Z_BEST_SPEED`). + - `2` + - `3` + - `4` + - `5` + - `6` (currently what `zlib.Z_DEFAULT_COMPRESSION` points to). + - `7` + - `8` + - `9` Best compression (also `zlib.Z_BEST_COMPRESSION`). + +The default value is `zlib.Z_DEFAULT_COMPRESSION`, or `-1`. + +**Note** in the list above, `zlib` is from `zlib = require('zlib')`. + +##### memLevel + +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). + +The default value is `zlib.Z_DEFAULT_MEMLEVEL`, or `8`. + +See [Node.js documentation](http://nodejs.org/api/zlib.html#zlib_memory_usage_tuning) +regarding the usage. + +##### 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.Z_DEFAULT_STRATEGY` Use for normal data. + - `zlib.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.Z_DEFAULT_STRATEGY` + and `zlib.Z_HUFFMAN_ONLY`. + - `zlib.Z_FIXED` Use to prevent the use of dynamic Huffman codes, allowing + for a simpler decoder for special applications. + - `zlib.Z_HUFFMAN_ONLY` Use to force Huffman encoding only (no string match). + - `zlib.Z_RLE` Use to limit match distances to one (run-length encoding). + This is designed to be almost as fast as `zlib.Z_HUFFMAN_ONLY`, but give + better compression for PNG image data. + +**Note** in the list above, `zlib` is from `zlib = require('zlib')`. + +##### threshold + +The byte threshold for the response body size before compression is considered +for the response, defaults to `1kb`. This is a number of bytes, any string +accepted by the [bytes](https://www.npmjs.com/package/bytes) module, or `false`. + +**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 + +The default value is `zlib.Z_DEFAULT_WINDOWBITS`, or `15`. + +See [Node.js documentation](http://nodejs.org/api/zlib.html#zlib_memory_usage_tuning) +regarding the usage. + +#### .filter + +The default `filter` function. This is used to construct a custom filter +function that is an extension of the default function. + +```js +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/connect + +When using this module with express or connect, 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 requests +app.use(compression()) + +// add all routes +``` + +### 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) + }) +}) +``` + +## License + +[MIT](LICENSE) + +[npm-image]: https://img.shields.io/npm/v/compression.svg +[npm-url]: https://npmjs.org/package/compression +[travis-image]: https://img.shields.io/travis/expressjs/compression/master.svg +[travis-url]: https://travis-ci.org/expressjs/compression +[coveralls-image]: https://img.shields.io/coveralls/expressjs/compression/master.svg +[coveralls-url]: https://coveralls.io/r/expressjs/compression?branch=master +[downloads-image]: https://img.shields.io/npm/dm/compression.svg +[downloads-url]: https://npmjs.org/package/compression +[gratipay-image]: https://img.shields.io/gratipay/dougwilson.svg +[gratipay-url]: https://www.gratipay.com/dougwilson/ http://git-wip-us.apache.org/repos/asf/incubator-griffin-site/blob/4f8fa326/node_modules/compression/index.js ---------------------------------------------------------------------- diff --git a/node_modules/compression/index.js b/node_modules/compression/index.js new file mode 100644 index 0000000..c0e801e --- /dev/null +++ b/node_modules/compression/index.js @@ -0,0 +1,276 @@ +/*! + * compression + * Copyright(c) 2010 Sencha Inc. + * Copyright(c) 2011 TJ Holowaychuk + * Copyright(c) 2014 Jonathan Ong + * Copyright(c) 2014-2015 Douglas Christopher Wilson + * MIT Licensed + */ + +'use strict' + +/** + * Module dependencies. + * @private + */ + +var accepts = require('accepts') +var bytes = require('bytes') +var compressible = require('compressible') +var debug = require('debug')('compression') +var onHeaders = require('on-headers') +var vary = require('vary') +var zlib = require('zlib') + +/** + * Module exports. + */ + +module.exports = compression +module.exports.filter = shouldCompress + +/** + * Module variables. + * @private + */ + +var cacheControlNoTransformRegExp = /(?:^|,)\s*?no-transform\s*?(?:,|$)/ + +/** + * Compress response data with gzip / deflate. + * + * @param {Object} [options] + * @return {Function} middleware + * @public + */ + +function compression (options) { + var opts = options || {} + + // options + var filter = opts.filter || shouldCompress + var threshold = bytes.parse(opts.threshold) + + if (threshold == null) { + threshold = 1024 + } + + return function compression (req, res, next) { + var ended = false + var length + var listeners = [] + var stream + + var _end = res.end + var _on = res.on + var _write = res.write + + // flush + res.flush = function flush () { + if (stream) { + stream.flush() + } + } + + // proxy + + res.write = function write (chunk, encoding) { + if (ended) { + return false + } + + if (!this._header) { + this._implicitHeader() + } + + return stream + ?
