# amazon-pa-api-5.0-sdk-node-ts
|
|
|

I downloaded Amazon's Product Advertising API SDK "Example."
|
|
|
|
I'm going to rebuild this mess so I can read it and understand it.
|
|
|
|
Here's to setting better examples.

# Product Advertising API 5.0 SDK for NodeJS
|
|
|
|
[](https://nodei.co/npm/paapi5-nodejs-sdk/)
|
|
|
|
[](http://badge.fury.io/js/paapi5-nodejs-sdk) [](https://www.npmjs.com/package/paapi5-nodejs-sdk)
|
|
|
|
This repository contains the official Product Advertising API 5.0 NodeJS SDK called **paapi5-nodejs-sdk** that allows you to access the [Product Advertising API](https://webservices.amazon.com/paapi5/documentation/index.html) from your NodeJS app.
|
|
|
|
## Installation
|
|
|
|
### For [Node.js](https://nodejs.org/)
|
|
|
|
The Product Advertising API NodeJS SDK can be installed via [npm](https://www.npmjs.com/package/paapi5-nodejs-sdk):
|
|
|
|
```shell
|
|
npm install paapi5-nodejs-sdk --save
|
|
```
|
|
|
|
You should now be able to `require('paapi5-nodejs-sdk')` in javascript files.
|
|
|
|
### For browser
|
|
|
|
The library also works in the browser environment via npm and [browserify](http://browserify.org/). After following
|
|
the above steps with Node.js and installing browserify with `npm install -g browserify`,
|
|
perform the following (assuming *main.js* is your entry file, that's to say your javascript file where you actually
|
|
use this library):
|
|
|
|
```shell
|
|
browserify main.js > bundle.js
|
|
```
|
|
|
|
Then include *bundle.js* in the HTML pages.
|
|
|
|
### Webpack Configuration
|
|
|
|
Using Webpack you may encounter the following error: "Module not found: Error:
|
|
Cannot resolve module", most certainly you should disable AMD loader. Add/merge
|
|
the following section to your webpack config:
|
|
|
|
```javascript
|
|
module: {
|
|
rules: [
|
|
{
|
|
parser: {
|
|
amd: false
|
|
}
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
## Getting Started
|
|
|
|
Please follow the [installation](#installation) instruction and execute the following JS code:
|
|
|
|
Simple example for [SearchItems](https://webservices.amazon.com/paapi5/documentation/search-items.html) to discover Amazon products with the keyword 'Harry Potter' in Books category:
|
|
|
|
```javascript
|
|
var ProductAdvertisingAPIv1 = require('paapi5-nodejs-sdk');
|
|
|
|
var defaultClient = ProductAdvertisingAPIv1.ApiClient.instance;
|
|
|
|
// Specify your credentials here. These are used to create and sign the request.
|
|
defaultClient.accessKey = '<YOUR ACCESS KEY>';
|
|
defaultClient.secretKey = '<YOUR SECRET KEY>';
