node.js SDK for AfterShip API

Installation

npm install aftership

Quick Start

const Aftership = require('aftership')('YOUR_API_KEY');

Aftership.call('GET', '/couriers/all', function (err, result) {
	if (err) {
		console.log(err);
	} else {
		console.log(result);
	}
});

// Or do it with promise 

Aftership.call('GET', '/couriers/all').then(function (result) {
	console.log(result);
}).catch(function (err) {
	console.log(err);
});

/** Console
{ meta: { code: 200 },
  data:

Constructor(api_key, options)

Create AfterShip instance with options

• api_key - Require - your Aftership API key
• options - Optional - object of request options
  • endpoint - string, AfterShip endpoint, default 'https://api.aftership.com/v4'
  • proxy - string, proxy, default is null
  • retry - boolean, retry if fail? default is true, see Retry policy
  • rate - boolean, retry if response with 429 Too Many request error see Rate Limiter
  • user_agent_prefix - string, prefix of User-Agent in headers, default 'aftership-sdk-nodejs'

Example:

// Construct with options
const Aftership = require('aftership')('YOUR_API_KEY', {
	endpoint: 'https://api.aftership.com/OLDER_VERSION',
	proxy: 'http://username:password@my.proxy.com',
	retry: false
});

// Make your call
Aftership.call('GET', '/couriers/all', function (err, result) {
	// ...
});

call(method, path, options, callback)

Make request with option

• method - Require - Either get, post, put or delete, case insensitive
• path - Require string, start with /, see available path here
• options - Optional - object of request options
  • api_key - string, AfterShip API key, override default api_key if set
  • body - object, POST body
  • query - object, query object
  • retry - boolean, retry if fail? override default retry if set, see Retry policy
  • raw - boolean, if true, return result as string, else return as object, default is false
• callback - the callback to handle error and result, the result is the response body of the request

Proxy Method (GET, POST, PUT, DELETE)

There are also interface GET, POST, PUT, DELETE which are proxy to Aftership.call(...)

Aftership.call('GET', '/path', options, callback);
// is equivalent to
Aftership.GET('/path', options, callback);

// So as `POST`, `PUT` and `DELETE`

Rate Limiter

To understand AfterShip rate limit policy, please see limit session in https://www.aftership.com/docs/api/4

You can get the recent rate limit by aftership.rate_limit. Initially all value are null.

const Aftership = require('aftership')('YOUR_API_KEY');
console.log(Aftership.rate_limit);

// console output
// { 'YOUR_API-KEY' : { reset: null, limit: null, remaining: null } }

After making an API call, it will be set.

Aftership.call('GET', '/couriers', function (err, result) {
	console.log(Aftership.rate_limit);
});

// console output
// { 'YOUR_API-KEY' : { limit: 600, remaining: 599, reset: 1453281417 } }

When the API response with 429 Too Many request error

• if rate is true, it wont throw, will delay the job, retry when the rate limit is reset.
• if rate is false, it will return 429 Too Many request error to the callback

Retry policy

To understand error of AfterShip, please see https://www.aftership.com/docs/api/4/errors

For this SDK, errors below are retriable.

• HTTP status code == [500, 502, 503, 504] from API
• ETIMEDOUT/ECONNRESET/ECONNREFUSED from node.js

You can set the retry flag

• in constructor as default retry flag
• specify in options of call() method

When an retriable error comes,

• if retry is true,
  • if retry_count < 5, use the same payload to retry after 1 second
  • if retry_count == 5, return the error to the callback, with retry_count
• if retry is false, return the error to the callback

Error Handling

There are 3 kinds of error

• SDK Error
• Request Error
• API Error

Error object of this SDK contain fields:

• type - Require - type of the error, please handle each error by this field
• message - Optional - detail message of the error
• data - Optional - data lead to the error
• code - Optional - error code for API Error
• response_body - Optional - response body of API Error
• retry_count - Optional - number of retry, if the error is retriable

Please handle each error by its type, since it is a require field

SDK Error

Error return by the SDK instance, mostly invalid param type when calling constructor or call function
error.type is one of error_enum
Throw by the SDK instance

const Aftership = require('aftership')('YOUR_API_KEY');

try {
	Aftership.call('INVALID_METHOD', '/couriers/all', function (err, result) {
		// ...
	});
} catch (e) {
	console.log(e);
}

/*
{ [Error: HandlerError: Invalid Method value]
  type: 'HandlerError',
  message: 'HandlerError: Invalid Method value',
  data: 'INVALID_METHOD' 
  ... }
*/

Request Error

Error return by the request module
error.type could be ETIMEDOUT, ECONNRESET, etc.
Catch by promise or Pass through the first param of callback

const Aftership = require('aftership')('YOUR_API_KEY');

Aftership.call('GET', '/couriers/all', function (err, result) {
	if (err) {
		console.log(err);
	}
});
/*
{ [Error]
  code: 'ECONNRESET',
  type: 'ECONNRESET' 
  ... }
*/

API Error

Error return by the Aftership API
error.type shuold be same as https://www.aftership.com/docs/api/4/errors
Catch by promise or Pass through the first param of callback

const Aftership = require('aftership')('INVALID_API_KEY');

Aftership.call('GET', '/couriers/all', function (err, result) {
	if (err) {
		console.log(err);
	}
});
/*
{ [Error: Invalid API key.]
  type: 'Unauthorized',
  message: 'Invalid API key.',
  code: 401,
  data: {},
  response_body: '{"meta":{"code":401,"message":"Invalid API key.","type":"Unauthorized"},"data":{}}' }
*/
