Matching and slicing on a huge input is often cause of slowdowns. +// The solution is to chunkify the input into smaller strings. +// The chunks are stored in the `chunks` var, +// `j` holds the current chunk index, and `current` holds +// the index of the current chunk in relation to `input`. +// This gives us an almost 4x speed-up. +// +// - In many cases, we don't need to match individual tokens; +// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS.

Matching and slicing on a huge input is often cause of slowdowns. +// The solution is to chunkify the input into smaller strings. +// The chunks are stored in the `chunks` var, +// `j` holds the current chunk index, and `current` holds +// the index of the current chunk in relation to `input`. +// This gives us an almost 4x speed-up. +// +// - In many cases, we don't need to match individual tokens; +// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS. This gives us a 50% speed-up in the parser, +// and a smaller speed-up in the code-gen. +// +// +// Token matching is done with the `$` function, which either takes +// a terminal string or regexp, or a non-terminal function to call. +// It also takes care of moving all the indices forwards. +// +// +less.Parser = function Parser(env) { + var input, // LeSS input string + i, // current index in `input` + j, // current chunk + temp, // temporarily holds a chunk's state, for backtracking + memo, // temporarily holds `i`, when backtracking + furthest, // furthest index the parser has gone to + chunks, // chunkified input + current, // index of current chunk, in `input` + parser; + + var that = this; + + // This function is called after all files + // have been imported through `@import`. + var finish = function () {}; + + var imports = this.imports = { + paths: env && env.paths || [], // Search paths, when importing + queue: [], // Files which haven't been imported yet + files: {}, // Holds the imported parse trees + mime: env && env.mime, // MIME type of .less files + push: function (path, callback) { + var that = this; + this.queue.push(path); + + // + // Import a file asynchronously + // + less.Parser.importer(path, this.paths, function (root) { + that.queue.splice(that.queue.indexOf(path), 1); // Remove the path from the queue + that.files[path] = root; // Store the root + + callback(root); + + if (that.queue.length === 0) { finish() } // Call `finish` if we're done importing + }, env); + } + }; + + function save() { temp = chunks[j], memo = i, current = i } + function restore() { chunks[j] = temp, i = memo, current = i } + + function sync() { + if (i > current) { + chunks[j] = chunks[j].slice(i - current); + current = i; + } + } + // + // Parse from a token, regexp or string, and move forward if match + // + function $(tok) { + var match, args, length, c, index, endIndex, k, mem; + + // + // Non-terminal + // + if (tok instanceof Function) { + return tok.call(parser.parsers); + // + // Terminal + // + // Either match a single character in the input, + // or match a regexp in the current chunk (chunk[j]). + // + } else if (typeof(tok) === 'string') { + match = input.charAt(i) === tok ? tok : null; + length = 1; + sync (); + } else { + sync (); + + if (match = tok.exec(chunks[j])) { + length = match[0].length; + } else { + return null; + } + } + + // The match is confirmed, add the match length to `i`, + // and consume any extra white-space characters (' ' || '\n') + // which come after that.

in the browser, several +// optimization had to be made: +// +// - Matching and slicing on a huge input is often cause of slowdowns. +// The solution is to chunkify the input into smaller strings. +// The chunks are stored in the `chunks` var, +// `j` holds the current chunk index, and `current` holds +// the index of the current chunk in relation to `input`. +// This gives us an almost 4x speed-up. +// +// - In many cases, we don't need to match individual tokens; +// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS.

+// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS.

    + +## Super simple to use + +Request is designed to be the simplest way possible to make http calls. It support HTTPS and follows redirects by default. + +```javascript +var request = require('request'); +request('http://www.google.com', function (error, response, body) { + if (!error && response.statusCode == 200) { + console.log(body) // Print the google web page. + } +}) +``` + +## Streaming + +You can stream any response to a file stream. + +```javascript +request('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png')) +``` + +You can also stream a file to a PUT or POST request. This method will also check the file extension against a mapping of file extensions to content-types, in this case `application/json`, and use the proper content-type in the PUT request if one is not already provided in the headers. + +```javascript +fs.createReadStream('file.json').pipe(request.put('http://mysite.com/obj.json')) +``` + +Request can also pipe to itself. When doing so the content-type and content-length will be preserved in the PUT headers. + +```javascript +request.get('http://google.com/img.png').pipe(request.put('http://mysite.com/img.png')) +``` + +Now let's get fancy. + +```javascript +http.createServer(function (req, resp) { + if (req.url === '/doodle.png') { + if (req.method === 'PUT') { + req.pipe(request.put('http://mysite.com/doodle.png')) + } else if (req.method === 'GET' || req.method === 'HEAD') { + request.get('http://mysite.com/doodle.png').pipe(resp) + } + } +}) +``` + +You can also pipe() from a http.ServerRequest instance and to a http.ServerResponse instance. The HTTP method and headers will be sent as well as the entity-body data. Which means that, if you don't really care about security, you can do: + +```javascript +http.createServer(function (req, resp) { + if (req.url === '/doodle.png') { + var x = request('http://mysite.com/doodle.png') + req.pipe(x) + x.pipe(resp) + } +}) +``` + +And since pipe() returns the destination stream in node 0.5.x you can do one line proxying :) + +```javascript +req.pipe(request('http://mysite.com/doodle.png')).pipe(resp) +``` + +Also, none of this new functionality conflicts with requests previous features, it just expands them. + +```javascript +var r = request.defaults({'proxy':'http://localproxy.com'}) + +http.createServer(function (req, resp) { + if (req.url === '/doodle.png') { + r.get('http://google.com/doodle.png').pipe(resp) + } +}) +``` + +You can still use intermediate proxies, the requests will still follow HTTP forwards, etc. + +## OAuth Signing + +```javascript +// Twitter OAuth +var qs = require('querystring') + , oauth = + { callback: 'http://mysite.com/callback/' + , consumer_key: CONSUMER_KEY + , consumer_secret: CONSUMER_SECRET + } + , url = 'https://api.twitter.com/oauth/request_token' + ; +request.post({url:url, oauth:oauth}, function (e, r, body) { + // Assume by some stretch of magic you aquired the verifier + var access_token = qs.parse(body) + , oauth = + { consumer_key: CONSUMER_KEY + , consumer_secret: CONSUMER_SECRET + , token: access_token.oauth_token + , verifier: VERIFIER + , token_secret: access_token.oauth_token_secret + } + , url = 'https://api.twitter.com/oauth/access_token' + ; + request.post({url:url, oauth:oauth}, function (e, r, body) { + var perm_token = qs.parse(body) + , oauth = + { consumer_key: CONSUMER_KEY + , consumer_secret: CONSUMER_SECRET + , token: perm_token.oauth_token + , token_secret: perm_token.oauth_token_secret + } + , url = 'https://api.twitter.com/1/users/show.json?' + , params = + { screen_name: perm_token.screen_name + , user_id: perm_token.user_id + } + ; + url += qs.stringify(params) + request.get({url:url, oauth:oauth, json:true}, function (e, r, user) { + console.log(user) + }) + }) +}) +``` + + + +### request(options, callback) + +The first argument can be either a url or an options object. The only required option is uri, all others are optional. + +* `uri` || `url` - fully qualified uri or a parsed url object from url.parse() +* `qs` - object containing querystring values to be appended to the uri +* `method` - http method, defaults to GET +* `headers` - http headers, defaults to {} +* `body` - entity body for POST and PUT requests. Must be buffer or string. +* `form` - sets `body` but to querystring representation of value and adds `Content-type: application/x-www-form-urlencoded; charset=utf-8` header. +* `json` - sets `body` but to JSON representation of value and adds `Content-type: application/json` header. +* `multipart` - (experimental) array of objects which contains their own headers and `body` attribute. Sends `multipart/related` request. See example below. +* `followRedirect` - follow HTTP 3xx responses as redirects. defaults to true. +* `followAllRedirects` - follow non-GET HTTP 3xx responses as redirects. defaults to false. +* `maxRedirects` - the maximum number of redirects to follow, defaults to 10. +* `encoding` - Encoding to be used on `setEncoding` of response data. If set to `null`, the body is returned as a Buffer. +* `pool` - A hash object containing the agents for these requests. If omitted this request will use the global pool which is set to node's default maxSockets. +* `pool.maxSockets` - Integer containing the maximum amount of sockets in the pool. +* `timeout` - Integer containing the number of milliseconds to wait for a request to respond before aborting the request +* `proxy` - An HTTP proxy to be used. Support proxy Auth with Basic Auth the same way it's supported with the `url` parameter by embedding the auth info in the uri. +* `oauth` - Options for OAuth HMAC-SHA1 signing, see documentation above. +* `strictSSL` - Set to `true` to require that SSL certificates be valid. Note: to use your own certificate authority, you need to specify an agent that was created with that ca as an option. +* `jar` - Set to `false` if you don't want cookies to be remembered for future use or define your custom cookie jar (see examples section) + + +The callback argument gets 3 arguments. The first is an error when applicable (usually from the http.Client option not the http.ClientRequest object). The second in an http.ClientResponse object. The third is the response body String or Buffer. + +## Convenience methods + +There are also shorthand methods for different HTTP METHODs and some other conveniences. + +### request.defaults(options) + +This method returns a wrapper around the normal request API that defaults to whatever options you pass in to it. + +### request.put + +Same as request() but defaults to `method: "PUT"`. + +```javascript +request.put(url) +``` + +### request.post + +Same as request() but defaults to `method: "POST"`. + +```javascript +request.post(url) +``` + +### request.head + +Same as request() but defaults to `method: "HEAD"`. + +```javascript +request.head(url) +``` + +### request.del + +Same as request() but defaults to `method: "DELETE"`. + +```javascript +request.del(url) +``` + +### request.get + +Alias to normal request method for uniformity. + +```javascript +request.get(url) +``` +### request.cookie + +Function that creates a new cookie. + +```javascript +request.cookie('cookie_string_here') +``` +### request.jar + +Function that creates a new cookie jar. + +```javascript +request.jar() +``` + + +## Examples: + +```javascript + var request = require('request') + , rand = Math.floor(Math.random()*100000000).toString() + ; + request( + { method: 'PUT' + , uri: 'http://mikeal.iriscouch.com/testjs/' + rand + , multipart: + [ { 'content-type': 'application/json' + , body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}}) + } + , { body: 'I am an attachment' } + ] + } + , function (error, response, body) { + if(response.statusCode == 201){ + console.log('document saved as: http://mikeal.iriscouch.com/testjs/'+ rand) + } else { + console.log('error: '+ response.statusCode) + console.log(body) + } + } + ) +``` +Cookies are enabled by default (so they can be used in subsequent requests).
