postman-code-generators
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:
| Language | Variant | |-----------|---------------| | C | libcurl | | C# | RestSharp | | cURL | cURL | | Dart | http | | Go | Native | | HTTP | HTTP | | Java | OkHttp | | Java | Unirest | | JavaScript | Fetch | | JavaScript | jQuery | | JavaScript | XHR | | NodeJs | Axios | | NodeJs | Native | | NodeJs | Request | | NodeJs | Unirest | | Objective-C| NSURLSession| | OCaml | Cohttp | |PHP | cURL | |PHP | pecl_http | |PHP | HTTP_Request2 | | PowerShell | RestMethod | | Python | http.client | | Python | Requests | | Ruby | Net:HTTP | | Shell | Httpie | | Shell | wget | | Swift | URLSession |

Getting Started
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
Prerequisite
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.
Usage
Using postman-code-generators as a Library
There are three functions that are exposed in postman-code-generators: getLanguageList, getOptions, and convert.
getLanguageList
This function returns a list of supported code generators.
Example:
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'
// }
// ]
// },
// ...
// ]
getOptions
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 functionvariant
- variant key provided by getLanguageList functioncallback
- 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 nameid
- unique ID of the optiontype
- 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 snippetdescription
- User friendly description.
Example:
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'
// },
// ...
// ];
convert
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 functionvariant
- variant key provided by getLanguageList functionrequest
- Postman-SDK Request Objectoptions
- Options that can be used to configure generated code snippet. Defaults will be used for the unspecified attributescallback
- callback function with first parameter as error and second parameter as string for code snippet
Example:
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
});
Development
Installing dependencies
This command will install all the dependencies in production mode.
$ npm install;
To install dev dependencies also for all codegens run:
$ npm run deepinstall dev;
Testing
To run common repo test as well as tests (common structure test + individual codegen tests) for all the codegens
$ npm test;
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
Packaging
To create zipped package of all codegens
$ npm run package;
Note: The zipped package is created inside each codegen's folder.
To create zipped package of a single codegen
$ npm run package <codegen-name>
