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.
- 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.
- Compiles Transaction Name string (vague identifier) for each Transaction.
- Provides Transaction Origin with pointers to API Elements derived from the original API description document.
Note: These features are to be superseded by whatever comes out of the proposal in apiaryio/dredd#227.
npm install dredd-transactions
Dredd Transactions library is written in JavaScript (ES2015+).
Parses given API description document into API Elements with options specific to Dredd. Assumes that documents with unrecognizable format are API Blueprint. Turns any parser failures, including the unexpected ones, into API Elements annotations.
const parse = require('dredd-transactions/parse');
// const { parse } = require('dredd-transactions');
parse('# My API\n...', (error, parseResult) => {
// ...
});Compiles HTTP Transactions from given API Elements. HTTP Transactions are a backbone data structure to Dredd.
const compile = require('dredd-transactions/compile');
// const { compile } = require('dredd-transactions');
const compileResult = compile(mediaType, apiElements, filename);Note: The
filenameargument is optional and about to get deprecated, see #6
Result of parsing.
mediaType:text/vnd.apiblueprint(string, default, nullable) - Media type of the input format, can be empty in case of some fatal errorsapiElements(API Elements) - API Elements parse result
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.
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 whatever comes out of the proposal in apiaryio/dredd#227.
- request (object) - HTTP Request as described in API description document.
