postman-collection-transformer

3.3.3 • Public • Published

Build Status

postman-collection-transformer

Perform rapid conversion of JSON structure between Postman Collection Format v1 and v2.

The formats are documented at https://schema.getpostman.com

Installation

For CLI usage:

$ npm install -g postman-collection-transformer

As a library:

$ npm install --save postman-collection-transformer

Usage

Converting Entire Collections

The transformer provides a Command line API to convert collections.

Example:

$ transform-collection convert \
    --input ./v1-collection.json \
    --input-version 2.0.0 \
    --output ./v2-collection.json \
    --output-version 1.0.0 \
    --pretty \
    --overwrite

All options:

$ transform-collection convert -h

  Usage: convert [options]

  Convert Postman Collection from one format to another

  Options:

    -h, --help                      output usage information
    -i, --input <path>              path to the input postman collection file
    -j, --input-version [version]   the version of the input collection format standard (v1 or v2)
    -o, --output <path>             target file path where the converted collection will be written
    -p, --output-version [version]  required version to which the collection is needed to be converted to
    -P, --pretty                    Pretty print the output
    --retain-ids                    Retain the request and folder IDs during conversion (collection ID is always retained)
    -w, --overwrite                 Overwrite the output file if it exists

If you'd rather use the transformer as a library:

    var transformer = require('postman-collection-transformer'),
        collection = require('./path/to/collection.json'),
        inspect = require('util').inspect,
 
        options = {
            inputVersion: '1.0.0',
            outputVersion: '2.0.0',
            retainIds: true  // the transformer strips request-ids etc by default.
        };
 
    transformer.convert(collection, options, function (error, result) {
        if (error) {
            return console.error(error);
        }
 
        // result <== the converted collection as a raw Javascript object
        console.log(inspect(result, {colors: true, depth: 10000}));
    });

Converting Individual Requests

The transformer also allows you to convert individual requests (only supported when used as a library):

Example
 
    var transformer = require('postman-collection-transformer'),
    
        objectToConvert = { /* A valid collection v1 Request or a collection v2 Item */ },
 
        options = {
            inputVersion: '1.0.0',
            outputVersion: '2.0.0',
            retainIds: true  // the transformer strips request-ids etc by default.
        };
 
    transformer.convertSingle(objectToConvert, options, function (err, converted) {
        console.log(converted);
    });

Converting Individual Responses

You can convert individual responses too if needed:

Example
 
    var transformer = require('postman-collection-transformer'),
    
        objectToConvert = { /* A v1 Response or a v2 Response */ },
 
        options = {
            inputVersion: '1.0.0',
            outputVersion: '2.0.0',
            retainIds: true  // the transformer strips request-ids etc by default.
        };
 
    transformer.convertResponse(objectToConvert, options, function (err, converted) {
        console.log(converted);
    });

Normalizing v1 collections

The transformer also provides a Command line API to normalize collections for full forward compatibility.

Example:

$ transform-collection normalize \
    --input ./v1-collection.json \
    --normalize-version 1.0.0 \
    --output ./v1-norm-collection.json \
    --pretty \
    --overwrite

All options:

$ transform-collection normalize -h

  Usage: normalize [options]

  Normalizes a postman collection according to the provided version


  Options:

    -i, --input <path>                 Path to the collection JSON file to be normalized
    -n, --normalize-version <version>  The version to normalizers the provided collection on
    -o, --output <path>                Path to the target file, where the normalized collection will be written
    -P, --pretty                       Pretty print the output
    --retain-ids                       Retain the request and folder IDs during conversion (collection ID is always retained)
    -w, --overwrite                    Overwrite the output file if it exists
    -h, --help                         Output usage information

If you'd rather use the transformer as a library:

    var transformer = require('postman-collection-transformer'),
        collection = require('./path/to/collection.json'),
        inspect = require('util').inspect,
 
        options = {
            normalizeVersion: '1.0.0',
            mutate: false, // performs in-place normalization, false by default.
            noDefaults: false, // when set to true, sensible defaults for missing properties are skipped. Default: false
            prioritizeV2: false, // when set to true, v2 attributes are used as the source of truth for normalization.
            retainEmptyValues: false, // when set to true, empty values are set to '', not removed. False by default.
            retainIds: true  // the transformer strips request-ids etc by default.
        };
 
    transformer.normalize(collection, options, function (error, result) {
        if (error) {
            return console.error(error);
        }
 
        // result <== the converted collection as a raw Javascript object
        console.log(inspect(result, {colors: true, depth: 10000}));
    });
