Craftgate Node.js Client

This repo contains the Node.js client for Craftgate API.

Requirements

• Node.js v4.x+
  • If you plan on using this library with older versions of Node (e.g. v0.10.x), you'll only need to include a Promise polyfill such as bluebird

Installation

$ npm install @craftgate/craftgate

Usage

To access the Craftgate API you'll first need to obtain API credentials (e.g. an API key and a secret key). If you don't already have a Craftgate account, you can signup at https://craftgate.io

Once you've obtained your API credentials, you can start using Craftgate by instantiating a CraftgateClient with your credentials.

const Craftgate = require('@craftgate/craftgate');

const craftgate = new Craftgate.Client({
  apiKey: '<YOUR API KEY>',
  secretKey: '<YOUR SECRET KEY>'
});

...

By default the Craftgate client connects to the production API servers at https://api.craftgate.io. For testing purposes, please use the sandbox URL https://sandbox-api.craftgate.io using the .

const Craftgate = require('@craftgate/craftgate');

const craftgate = new Craftgate.Client({
  apiKey: '<YOUR API KEY>',
  secretKey: '<YOUR SECRET KEY>',
  baseUrl: 'https://sandbox-api.craftgate.io'
});

Bulk Import vs. Individual Imports

The root export of the project (e.g. @craftgate/craftgate) is designed primarily for CommonJS-style bulk imports, but the project also exports its modules individually, so you can also import them directly in ES6 fashion. On development environments where a transpiler such as Babel or TypeScript exists, we recommend using this approach.

Keep in mind that when using direct imports, you'll have to import necessary modules individually. So this code:

const Craftgate = require('@craftgate/craftgate');

const craftgate = new Craftgate.Client({...});

craftgate.payment().createPayment({
  ...,
  currency: Craftgate.Model.Currency.TRY,
  ...
})
...

becomes like this:

import CraftgateClient from '@craftgate/craftgate/CraftgateClient';
import Currency from '@craftgate/craftgate/model/Currency';

const craftgate = new CraftgateClient({...});

craftgate.payment().createPayment({
  ...,
  currency: Currency.TRY,
  ...
})
...

Also, since we make use of default exports, if you wish to import these modules directly in CommonJS fashion (e.g. require()), then make sure you're accessing the default keyword of the module.

const CraftgateClient = require('@craftgate/craftgate/CraftgateClient'); // this won't work

...

const CraftgateClient = require('@craftgate/craftgate/CraftgateClient').default; // however, this will

Examples

Included in the project are a number of examples that cover almost all use-cases. Refer to the samples/ folder] for more info.

Aside from demonstrating different business use cases, we also added technically different variants of certain examples to reflect the diversity in technical stacks. These examples are located under the samples/misc folder, and what they represent are indicated by filename suffixes listed below:

Filename Suffix	Description
.es5.js	ES5-style JavaScript code with bulk CommonJS imports (e.g. var keyword for variables, require() keyword for imports, inline function() blocks)
.es6.js	ES6-style JavaScript code with ES6 imports (e.g. let/const keyword for variables, import keyword for imports, lambda expressions)
.ts	TypeScript code
.js	Node.js v6+ (ES6-style JavaScript code with direct CommonJS imports) (e.g. let/const keyword for variables, require() keyword for imports, lambda expressions)

Running the Examples

If you've cloned this repo on your development machine and wish to run the examples directly, make sure to install the dependencies using npm i and build the library using npm run build. Once the library is built, you can run an example with the command node <example path> (e.g. node samples/payment/RetrievePayment.js).

Keep in mind that the node interpreter cannot be used to execute TypeScript files, whereas the ts-node can. This interpreter does not ship with Node.js itself, so you'll either have to install it globally on your machine, or include it in your project as a dependency. This repository already includes it as a dev dependency, and exposes it as an NPM task with the namets-node, so to run a TypeScript example you can simply execute the command npm run ts-node <example path> (e.g. npm run ts-node samples/misc/CreatePayment.ts).

Credit Card Payment Use Case (ES5-Style)

Let's quickly review an example where we implement a credit card payment scenario using an ES5-style approach

For more examples covering almost all use-cases, check out the examples in the samples/ folder

var Craftgate = require('../dist');

var craftgate = new Craftgate.Client({
  apiKey: 'api-key',
  secretKey: 'secret-key',
  baseUrl: 'https://sandbox-api.craftgate.io'

craftgate.payment().createPayment(request)
  .then(function(result) {
    console.info('Payment successful', result);
  })
  .catch(function(err) {
    console.error('Payment failed', err);
