Description
AWS SDK for JavaScript STS Client for Node.js, Browser and React Native.
Security Token Service
Security Token Service (STS) enables you to request temporary, limited-privilege credentials for users. This guide provides descriptions of the STS API. For more information about using this service, see Temporary Security Credentials.
Installing
To install this package, use the CLI of your favorite package manager:
npm install @aws-sdk/client-stsyarn add @aws-sdk/client-stspnpm add @aws-sdk/client-sts
Getting Started
Import
The AWS SDK is modulized by clients and commands.
To send a request, you only need to import the STSClient and
the commands you need, for example GetCallerIdentityCommand:
// ES5 example
const { STSClient, GetCallerIdentityCommand } = require("@aws-sdk/client-sts");
// ES6+ example
import { STSClient, GetCallerIdentityCommand } from "@aws-sdk/client-sts";
Usage
To send a request:
- Instantiate a client with configuration (e.g. credentials, region).
- See docs/CLIENTS for configuration details.
- See @aws-sdk/config for additional options.
- Instantiate a command with input parameters.
- Call the
sendoperation on the client, providing the command object as input.
const client = new STSClient({ region: "REGION" });
const params = { /** input parameters */ };
const command = new GetCallerIdentityCommand(params);
Async/await
We recommend using the 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.
}
Promises
You can also use Promise chaining.
client
.send(command)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
})
.finally(() => {
// finally.
});
Aggregated client
The aggregated client class is exported from the same package, but without the "Client" suffix.
STS extends STSClient and additionally supports all operations, waiters, and paginators as methods.
This style may be familiar to you from the AWS SDK for JavaScript v2.
If you are bundling the AWS SDK, we recommend using only the bare-bones client (STSClient).
More details are in the blog post on
modular packages in AWS SDK for JavaScript.
import { STS } from "@aws-sdk/client-sts";
const client = new STS({ region: "REGION" });
// async/await.
try {
const data = await client.getCallerIdentity(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.getCallerIdentity(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks (not recommended).
client.getCallerIdentity(params, (err, data) => {
// process err and data.
});
Troubleshooting
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;
* }
*/
}
