Usage

This is the core set of plugins that restify ships with. These include lots of header parsing handlers, data parsing handlers, as well as other useful logging/metrics handlers.

This module includes the follow pre plugins, which are intended to be used prior to the routing of a request:

  • sanitizePath() - cleans up duplicate or trailing / on the URL
  • userAgent(options) - used to support edge cases for HEAD requests when using curl
    • options.userAgentRegExp {RegExp} regexp to capture curl user-agents

This module includes the following header parser plugins:

  • acceptParser(accepts) - Accept header
    • accepts {Array} an array of acceptable types
  • authorizationParser(options) - Authorization header
    • options {Object} options object passed to http-signature module
  • conditionalRequest() - Conditional headers (If-*)
  • fullResponse() - handles disappeared CORS headers

This module includes the following data parsing plugins:

  • auditLogger(options) - an audit logger for recording all handled requests
    • options.log {Object} bunyan logger
    • options.body {?}
  • bodyParser(options) - parses POST bodies to req.body. automatically uses one of the following parsers based on content type:
    • urlEncodedBodyParser(options) - parses url encoded form bodies
    • jsonBodyParser(options) - parses JSON POST bodies
    • multipartBodyParser(options) - parses multipart form bodies
    • All bodyParsers support the following options:
      • options.mapParams - default false. copies parsed post body values onto req.params
      • options.overrideParams - default false. only applies when if mapParams true. when true, will stomp on req.params value when existing value is found.
  • jsonp() - parses JSONP callback
  • queryParser() - parses URL query paramters
    • options.mapParams - default false. copies parsed post body values onto req.params
    • options.overrideParams - default false. only applies when if mapParams true. when true, will stomp on req.params value when existing value is found.
  • requestLogger(options) - adds timers for each handler in your request chain
    • options.properties {Object} properties to pass to bunyan's log.child() method

The module includes the following response plugins:

  • dateParser(delta) - expires requests based on current time + delta

    • delta {Number} age in seconds

  • gzip(options) - gzips the response if client accepts it

    • options {Object} options to pass to zlib

  • serveStatic() - used to serve static files

    • options.checkIfModified {Boolean} if true, will check file modified date to send a 304.

  • throttle(options) - throttles responses

    • options.burst {Number}
    • options.rate {Number}
    • options.ip {Boolean}
    • options.username {Boolean}
    • options.xff {Boolean}
    • options.overrides {Object}

  • requestExpiry(options) - A request expiry will use headers to tell if the incoming request has expired or not. There are two options for this plugin:

    1. Absolute Time
      • Time in Milliseconds since the Epoch when this request should be considered expired
    2. Timeout
      • The request start time is supplied
      • A timeout, in milliseconds, is given
      • The timeout is added to the request start time to arrive at the absolute time in which the request is considered expires
    • options.absoluteHeader {String} header name of the absolute time for request expiration
    • options.startHeader {String} header name for the start time of the request
    • options.timeoutHeader {String} The header name for the time in milliseconds that should ellapse before the request is considered expired.
