/**
|
* A restify server object is the main interface through which you will register
|
* routes and handlers for incoming requests.
|
*
|
* @public
|
* @function createServer
|
* @param {Object} [options] - an options object
|
* @param {String} [options.name="restify"] - Name of the server.
|
* @param {Boolean} [options.dtrace=false] - enable DTrace support
|
* @param {Router} [options.router=new Router(opts)] - Router
|
* @param {Object} [options.log=bunyan.createLogger(options.name || "restify")]
|
* - [bunyan](https://github.com/trentm/node-bunyan) instance.
|
* @param {String} [options.url] - Once listen() is called, this will be filled
|
* in with where the server is running.
|
* @param {String|Buffer} [options.certificate] - If you want to create an HTTPS
|
* server, pass in a PEM-encoded certificate and key.
|
* @param {String|Buffer} [options.key] - If you want to create an HTTPS server,
|
* pass in a PEM-encoded certificate and key.
|
* @param {Object} [options.formatters] - Custom response formatters for
|
* `res.send()`.
|
* @param {Boolean} [options.handleUncaughtExceptions=false] - When true restify
|
* will use a domain to catch and respond to any uncaught
|
* exceptions that occur in it's handler stack.
|
* [bunyan](https://github.com/trentm/node-bunyan) instance.
|
* response header, default is `restify`. Pass empty string to unset the header.
|
* Comes with significant negative performance impact.
|
* @param {Object} [options.spdy] - Any options accepted by
|
* [node-spdy](https://github.com/indutny/node-spdy).
|
* @param {Object} [options.http2] - Any options accepted by
|
* [http2.createSecureServer](https://nodejs.org/api/http2.html).
|
* @param {Boolean} [options.handleUpgrades=false] - Hook the `upgrade` event
|
* from the node HTTP server, pushing `Connection: Upgrade` requests through the
|
* regular request handling chain.
|
* @param {Boolean} [options.onceNext=false] - Prevents calling next multiple
|
* times
|
* @param {Boolean} [options.strictNext=false] - Throws error when next() is
|
* called more than once, enabled onceNext option
|
* @param {Object} [options.httpsServerOptions] - Any options accepted by
|
* [node-https Server](http://nodejs.org/api/https.html#https_https).
|
* If provided the following restify server options will be ignored:
|
* spdy, ca, certificate, key, passphrase, rejectUnauthorized, requestCert and
|
* ciphers; however these can all be specified on httpsServerOptions.
|
* @param {Boolean} [options.noWriteContinue=false] - prevents
|
* `res.writeContinue()` in `server.on('checkContinue')` when proxing
|
* @param {Boolean} [options.ignoreTrailingSlash=false] - ignore trailing slash
|
* on paths
|
* @param {Boolean} [options.strictFormatters=true] - enables strict formatters
|
* behavior: a formatter matching the response's content-type is required. If
|
* not found, the response's content-type is automatically set to
|
* 'application/octet-stream'. If a formatter for that content-type is not
|
* found, sending the response errors.
|
* @example
|
* var restify = require('restify');
|
* var server = restify.createServer();
|
*
|
* server.listen(8080, function () {
|
* console.log('ready on %s', server.url);
|
* });
|
* @returns {Server} server
