The [Amazon SDK for JavaScript V3 API Reference Guide](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/) describes in detail all the API operations for the Amazon SDK for JavaScript version 3 (V3). 

# Configure proxies for Node.js
<a name="node-configuring-proxies"></a>

If you can't directly connect to the internet, the SDK for JavaScript supports use of HTTP or HTTPS proxies through a third-party HTTP agent.

To find a third-party HTTP agent, search for "HTTP proxy" at [npm](https://www.npmjs.com/).

To install a third-party HTTP agent proxy, enter the following at the command prompt, where {{PROXY}} is the name of the `npm` package. 

```
npm install {{PROXY}} --save
```

To use a proxy in your application, use the `httpAgent` and ` httpsAgent` property, as shown in the following example for a DynamoDB client. 

```
import { DynamoDBClient } from '@aws-sdk/client-dynamodb';
import { NodeHttpHandler } from "@smithy/node-http-handler";
import { HttpsProxyAgent } from "hpagent";
const agent = new HttpsProxyAgent({ proxy: "http://internal.proxy.com" });
const dynamodbClient = new DynamoDBClient({
    requestHandler: new NodeHttpHandler({
        httpAgent: agent,
        httpsAgent: agent
    }),
});
```

**Note**  
`httpAgent` is not the same as `httpsAgent`, and since most calls from the client will be to `https`, both should be set.
