    npm version Build Status Build status Dependencies Status devDependencies Status Greenkeeper badge Coverage Status Known Vulnerabilities

    Dredd Transactions library compiles HTTP Transactions (simple Request-Response pairs) from API description document.

    Note: To better understand emphasized terms in this documentation, please refer to the Glossary of Terms. All data structures are described using the MSON format.

    This project supersedes Blueprint Transactions library.

    Note

    This is a fork of the https://github.com/apiaryio/dredd-transactions repo to use the js version of drafter so there are no C++ compiles happening.

    Features

    • Inherits parameters from parent Resource and Action sections.
    • Expands URI Templates.
    • Warns on undefined placeholders in URI Templates (both query and path).
    • Validates URI parameter types.
    • Selects first Request and first Response if multiple are specified in the API description document.

    Deprecated Features

    Note: These features are to be superseded by so-called Transaction Path. Feel free to read and comment the proposal in apiaryio/dredd#227.

    Installation

    npm install dredd-transactions
    

    Development

    Dredd Transactions library is written in JavaScript (ES2015+).

    Usage

    compile

    Compiles HTTP Transactions from given API description document.

    var dt = require('dredd-transactions');
     
    dt.compile('# My API\n...', 'apiary.apib', function (error, compilationResult) {
      // ...
    });

    Arguments

    • (string) - API description document provided as string.
    • (string) - Original file name of the API description document. Soon to be removed! See #6.
    • (function) - Callback.

    Callback Arguments

    Data Structures

    Compilation Result (object)

    Result of compilation. Alongside compiled Transaction objects contains also errors and warnings, mainly from API description parser.

    • mediaType: text/vnd.apiblueprint (string, default, nullable) - Media type of the input format, defaults to API Blueprint format. Can be empty in case of some fatal errors.
    • transactions (array[Transaction]) - Compiled HTTP Transactions.
    • annotations (array[Annotation]) - Errors and warnings which occurred during parsing of the API description or during compilation of transactions.

    Transaction (object)

    Represents a single HTTP Transaction (Request-Response pair) and its location in the API description document. The location is provided in two forms, both deprecated as of now:

    • name - String representation, both human- and machine-readable.
    • origin - Object of references to nodes of API Elements derived from the original API description document.

    Note: These two forms of locating HTTP Transactions are to be superseded by so-called Transaction Path. Feel free to read and comment the proposal in apiaryio/dredd#227.

    Properties

    • request (object) - HTTP Request as described in API description document.
      • method
      • uri: /message (string) - Informative URI of the Request.
      • headers (array) - List of HTTP headers in their original order, with the original casing of the header name, including multiple headers of the same name.
        • (object)
          • name: Content-Type (string)
          • value: text/plain (string)
      • body: Hello world!\n (string)
    • response (object) - Expected HTTP Response as described in API description document.
      • status: 200 (string)
      • headers (array) - List of HTTP headers in their original order, with the original casing of the header name, including multiple headers of the same name.
        • (object)
          • name: Content-Type (string)
          • value: text/plain (string)
      • body (string, optional)
      • schema (string, optional)

    Deprecated Properties

    • name: Hello world! > Retrieve Message (string) - Transaction Name, non-deterministic breadcrumb location of the HTTP Transaction within the API description document.
    • origin (object) - Object of references to nodes of API Elements derived from the original API description document.
      • filename: ./api-description.apib (string)
      • apiName: My Api (string)
      • resourceGroupName: Greetings (string)
      • resourceName: Hello, world! (string)
      • actionName: Retrieve Message (string)
      • exampleName: First example (string)

    Note: These properties are to be superseded by so-called Transaction Path. Feel free to read and comment the proposal in apiaryio/dredd#227.

    Annotation (object)

    Description of an error or warning which occurred during parsing of the API description or during compilation of transactions.

    Properties

    • type (enum[string])
      • error
      • warning
    • component (enum[string]) - In which component of the compilation process the annotation occurred.
      • apiDescriptionParser
      • parametersValidation
      • uriTemplateExpansion
    • message (string) - Textual annotation. This is – in most cases – a human-readable message to be displayed to user.
    • location (array) - Locations of the annotation in the source file. A series of character-blocks, which may be non-continuous. For further details refer to API Elements' Source Map element.
      • (array, fixed) - Continuous characters block. A pair of character index and character count.
        • (number) - Zero-based index of a character in the source document.
        • (number) - Count of characters starting from the character index.

    Deprecated Properties

    • origin (object) - Object of references to nodes of API Elements derived from the original API description document.
      • filename: ./api-description.apib (string)
      • apiName: My Api (string)
      • resourceGroupName: Greetings (string)
      • resourceName: Hello, world! (string)
      • actionName: Retrieve Message (string)
      • exampleName: First example (string)

    Note: These properties are to be superseded by so-called Transaction Path. Feel free to read and comment the proposal in apiaryio/dredd#227.
