service-client

javascript wrapper function for http.request and https.request that returns parsed, transformed data in callback.

This probject is archived - the features here can be achieved easily enough with something like node-fetch and parsing the response.

API

get(url, options, callback)

• url

  The URL to access

• options

  Optional. An object specifying the options for the request, parsing and transformation.
  

  • accept: Accept request header (string). Defaults to text/plain

    • "text" or "plain" are changed to text/plain
    • "json" is changed to application/json
    • "xml" is changed to application/xml

  • parse: function used to parse the data returned from http(s) request. Default returns the data Buffer as-is in the callback

    Given 2 parameters:

    • buffer: The Buffer that holds the data returned from the http(s) request
    • callback: Callback function taking two paramers (err, data)

    If parse is a string, one of the internal parsers are returned:

    • "json": wraps JSON.parse
    • "raw": returns the data data as-is

  • transform: function used to transform the parsed data. Default returns the data as-is is the callback. Given 2 parameters:

    • data: The data returned from the parse function
    • callback: Callback function taking two paramers (err, data)

  • protocol: string to specify if http or https should be used. Default depends on protocol returned by url.parse

  • http: function used for http.request. Used for mocking

  • https: function used for https.request. Used for mocking

• callback

  The callback function called when an error has occured or when the data was received, parsed and transformed
  Parameters:

  • err: null when no error has occured or an error details object with the keys:

    • error: The actual error that was caught
    • action: The action where the error occured (request, response, parse, transform)
    • length: The value of the content-length header
    • received: The number of bytes received so far
    • buffer: The Buffer object that is used to hold the data returned from the http(s) response
    • parsed: The parsed data

    If the content-length response header is not present, length will be -1 (while transfering) or the number of bytes received when the end event is fired

  • data: The transformed data. undefined if an error has occured.

mock.Builder(options)

Class to build http/https mocks

• options:

  • statusCode: number to use as the status code for the request. Defaults to 200
  • data: text to return for the request. Defaults to empty string

mock.Builder.httpRequest(url, callback)

Wrapper for http.request and https.request. Returns a new mock.RequestMock setup to call callback on end with a new mock.ResponseMock

mock.RequestMock(requestCallback, response)

• requestCallback: The callback that will get the response object
• response: The response object / mock.ResponseMock to return on end

mock.ResponseMock(dataToReturn)

• dataToReturn: The data to return

mock.get(rules)

• rules: object where keys are the urls, and values are functions (taking a single callback function parameter) that is used to match incomming requests to the mock

Dependencies

• defaultify

  Handles options setup for get defaultify on npm
