postmanlabs/postman-code-generators: Common repository for all code generators shipped with Postman

Manage all of your organization's APIs in Postman, with the industry's most complete API development environment.

Supercharge your API workflow.
Modern software is built on APIs. Postman helps you develop APIs faster.

This module converts a Postman SDK Request Object into a code snippet of chosen language.

Every code generator has two identifiers: language and variant.

language of a code generator is the programming language in which the code snippet is generated.
variant of a code generator is the methodology or the underlying library used by the language to send requests.

List of supported code generators:

[postman-code-generators

To install postman-code-generators as your dependency

$ npm install postman-code-generators

To get a copy on your local machine

$ git clone https://github.com/postmanlabs/postman-code-generators.git

To run any of the postman-code-generators, ensure that you have NodeJS >= v8. A copy of the NodeJS installable can be downloaded from https://nodejs.org/en/download/package-manager.

Using postman-code-generators as a Library

There are three functions that are exposed in postman-code-generators: getLanguageList, getOptions, and convert.

This function returns a list of supported code generators.

var codegen = require('postman-code-generators'), // require postman-code-generators in your project
    supportedCodegens = codegen.getLanguageList();
    console.log(supportedCodegens);
    // output:
    // [
    //   {
    //     key: 'nodejs',
    //     label: 'NodeJs',
    //     syntax_mode: 'javascript',
    //     variant: [
    //       {
    //         key: 'Requests'
    //       },
    //       {
    //         key: 'Native'
    //       },
    //       {
    //         key: 'Unirest'
    //       }
    //     ]
    //   },
    //   ...
    // ]

This function takes in three parameters and returns a callback with error and supported options of that code generator.

language - language key from the language list returned from getLanguageList function
variant - variant key provided by getLanguageList function
callback - callback function with first parameter as error and second parameter as array of options supported by the codegen.

A typical option has the following properties:

name - Display name
id - unique ID of the option
type - Data type of the option. (Allowed data types: boolean, enum, positiveInteger)
default - Default value. The value that is used if this option is not specified while creating code snippet
description - User friendly description.

var codegen = require('postman-code-generators'), // require postman-code-generators in your project
    language = 'nodejs',
    variant = 'Request';

    codegen.getOptions(language, variant, function (error, options) {
      if (error) {
        // handle error
      }
      console.log(options);
    });
// output: 
//     [
//     {
//       name: 'Set indentation count',
//       id: 'indentCount',
//       type: 'positiveInteger',
//       default: 2,
//       description: 'Set the number of indentation characters to add per code level'
//     },
//     {
//       name: 'Set indentation type',
//       id: 'indentType',
//       type: 'enum',
//       availableOptions: ['Tab', 'Space'],
//       default: 'Space',
//       description: 'Select the character used to indent lines of code'
//     },
//     ...
//   ];

This function takes in five parameters and returns a callback with error and generated code snippet

language - lang key from the language list returned from getLanguageList function
variant - variant key provided by getLanguageList function
request - Postman-SDK Request Object
options - Options that can be used to configure generated code snippet. Defaults will be used for the unspecified attributes
callback - callback function with first parameter as error and second parameter as string for code snippet

var codegen = require('postman-code-generators'), // require postman-code-generators in your project
    sdk = require('postman-collection'), // require postman-collection in your project
    request = new sdk.Request('https://www.google.com'),  //using postman sdk to create request 
    language = 'nodejs',
    variant = 'request',
    options = {
        indentCount: 3,
        indentType: 'Space',
        trimRequestBody: true,
        followRedirect: true
    };
codegen.convert(language, variant, request, options, function(error, snippet) {
    if (error) {
        //  handle error
    }
    //  handle snippet
});

This command will install all the dependencies in production mode.

To install dev dependencies also for all codegens run:

$ npm run deepinstall dev;

To run common repo test as well as tests (common structure test + individual codegen tests) for all the codegens

To run structure and individual tests on a single codegen

$ npm test <codegen-name>;
# Here "codege-name" is the folder name of the codegen inside codegens folder

To create zipped package of all codegens

Note: The zipped package is created inside each codegen's folder.

To create zipped package of a single codegen

$ npm run package <codegen-name>
