Aws-sdk-v3-proxy NPM

AWS SDK v3 Proxy

A wrapper for adding proxy support to AWS SDK v3 clients

This wrapper adds a proxy configuration to AWS SDK clients by checking environment variables and attaching the necessary request handler. By default, an error will be thrown if no proxy is found in process.env, but also has options to not throw which can be useful when developing other node utilities using this library.

Note: http_proxy and HTTP_PROXY take precedence over https_proxy and HTTPS_PROXY. If you would like to change this behavior it can be specified in the options.

Install

npm install aws-sdk-v3-proxy

Usage

HTTP Proxy

// process.env.HTTP_PROXY = 'http://127.0.0.1'
import { S3Client } from '@aws-sdk/client-s3';
import { addProxyToClient } from 'aws-sdk-v3-proxy';

const client = addProxyToClient(new S3Client({}));
// `client` now has HTTP proxy config at 'http://127.0.0.1'

import { S3Client } from '@aws-sdk/client-s3';
import { addProxyToClient } from 'aws-sdk-v3-proxy';

const client = addProxyToClient(new S3Client({}), {
  httpProxy: 'http://127.0.0.1',
});
// `client` now has HTTP proxy config at 'http://127.0.0.1'

HTTPS Proxy

// process.env.HTTPS_PROXY = 'https://127.0.0.1'
import { S3Client } from '@aws-sdk/client-s3';
import { addProxyToClient } from 'aws-sdk-v3-proxy';

const client = addProxyToClient(new S3Client({}));
// `client` now has HTTPS proxy config at 'https://127.0.0.1'

import { S3Client } from '@aws-sdk/client-s3';
import { addProxyToClient } from 'aws-sdk-v3-proxy';

const client = addProxyToClient(new S3Client({}), {
  httpsProxy: 'https://127.0.0.1',
});
// `client` now has HTTPS proxy config at 'https://127.0.0.1'

No Proxy with exception disabled

// process.env.HTTPS_PROXY = undefined
// process.env.HTTP_PROXY = undefined
import { S3Client } from '@aws-sdk/client-s3';
import { addProxyToClient } from 'aws-sdk-v3-proxy';

const client = addProxyToClient(new S3Client({}), { throwOnNoProxy: false });
// `client` has no proxy assigned and no error thrown

Proxy with certs in header

// process.env.HTTPS_PROXY = 'https://127.0.0.1'
import { readFileSync } from 'fs';
import { S3Client } from '@aws-sdk/client-s3';
import { addProxyToClient } from 'aws-sdk-v3-proxy';

const client = addProxyToClient(new S3Client({}), {
  agentOptions: {
    ca: [readFileSync('custom-proxy-cert.pem').toString()],
  },
});

// `client` now has HTTPS proxy config at 'https://127.0.0.1' with ca `custom-proxy-cert.pem`
