AWS SDK for JavaScript DirectConnect Client for Node.js, Browser and React Native.
Direct Connect links your internal network to an Direct Connect location over a standard Ethernet fiber-optic cable. One end of the cable is connected to your router, the other to an Direct Connect router. With this connection in place, you can create virtual interfaces directly to the Amazon Web Services Cloud (for example, to Amazon EC2 and Amazon S3) and to Amazon VPC, bypassing Internet service providers in your network path. A connection provides access to all Amazon Web Services Regions except the China (Beijing) and (China) Ningxia Regions. Amazon Web Services resources in the China Regions can only be accessed through locations associated with those Regions.
To install the this package, simply type add or install @aws-sdk/client-direct-connect using your favorite package manager:
npm install @aws-sdk/client-direct-connectyarn add @aws-sdk/client-direct-connectpnpm add @aws-sdk/client-direct-connect
The AWS SDK is modulized by clients and commands.
To send a request, you only need to import the DirectConnectClient and
the commands you need, for example ListVirtualInterfaceTestHistoryCommand:
// ES5 example
const { DirectConnectClient, ListVirtualInterfaceTestHistoryCommand } = require("@aws-sdk/client-direct-connect");// ES6+ example
import { DirectConnectClient, ListVirtualInterfaceTestHistoryCommand } from "@aws-sdk/client-direct-connect";To send a request, you:
- Initiate client with configuration (e.g. credentials, region).
- Initiate command with input parameters.
- Call
sendoperation on client with command object as input. - If you are using a custom http handler, you may call
destroy()to close open connections.
// a client can be shared by different commands.
const client = new DirectConnectClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new ListVirtualInterfaceTestHistoryCommand(params);We recommend using await operator to wait for the promise returned by send operation as follows:
// async/await.
try {
const data = await client.send(command);
// process data.
} catch (error) {
// error handling.
} finally {
// finally.
}Async-await is clean, concise, intuitive, easy to debug and has better error handling as compared to using Promise chains or callbacks.
You can also use Promise chaining to execute send operation.
client.send(command).then(
(data) => {
// process data.
},
(error) => {
// error handling.
}
);Promises can also be called using .catch() and .finally() as follows:
client
.send(command)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
})
.finally(() => {
// finally.
});We do not recommend using callbacks because of callback hell, but they are supported by the send operation.
// callbacks.
client.send(command, (err, data) => {
// process err and data.
});The client can also send requests using v2 compatible style. However, it results in a bigger bundle size and may be dropped in next major version. More details in the blog post on modular packages in AWS SDK for JavaScript
import * as AWS from "@aws-sdk/client-direct-connect";
const client = new AWS.DirectConnect({ region: "REGION" });
// async/await.
try {
const data = await client.listVirtualInterfaceTestHistory(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.listVirtualInterfaceTestHistory(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.listVirtualInterfaceTestHistory(params, (err, data) => {
// process err and data.
});When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id).
try {
const data = await client.send(command);
// process data.
} catch (error) {
const { requestId, cfId, extendedRequestId } = error.$metadata;
console.log({ requestId, cfId, extendedRequestId });
/**
* The keys within exceptions are also parsed.
* You can access them by specifying exception names:
* if (error.name === 'SomeServiceException') {
* const value = error.specialKeyInException;
* }
