## Description
|
||
|
|
|
||
|
|
AWS SDK for JavaScript STS Client for Node.js, Browser and React Native.
|
||
|
|
|
||
|
|
<fullname>Security Token Service</fullname>
|
||
|
|
|
||
|
|
<p>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 <a href="https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp.html">Temporary Security Credentials</a>.</p>
|
||
|
|
|
||
|
|
## Installing
|
||
|
|
|
||
|
|
To install the this package, simply type add or install @aws-sdk/client-sts
|
||
|
|
using your favorite package manager:
|
||
|
|
|
||
|
|
- `npm install @aws-sdk/client-sts`
|
||
|
|
- `yarn add @aws-sdk/client-sts`
|
||
|
|
- `pnpm 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`:
|
||
|
|
|
||
|
|
```js
|
||
|
|
// ES5 example
|
||
|
|
const { STSClient, GetCallerIdentityCommand } = require("@aws-sdk/client-sts");
|
||
|
|
```
|
||
|
|
|
||
|
|
```ts
|
||
|
|
// ES6+ example
|
||
|
|
import { STSClient, GetCallerIdentityCommand } from "@aws-sdk/client-sts";
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
To send a request, you:
|
||
|
|
|
||
|
|
- Initiate client with configuration (e.g. credentials, region).
|
||
|
|
- Initiate command with input parameters.
|
||
|
|
- Call `send` operation on client with command object as input.
|
||
|
|
- If you are using a custom http handler, you may call `destroy()` to close open connections.
|
||
|
|
|
||
|
|
```js
|
||
|
|
// a client can be shared by different commands.
|
||
|
|
const client = new STSClient({ region: "REGION" });
|
||
|
|
|
||
|
|
const params = {
|
||
|
|
/** input parameters */
|
||
|
|
};
|
||
|
|
const command = new GetCallerIdentityCommand(params);
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Async/await
|
||
|
|
|
||
|
|
We recommend using [await](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/await)
|
||
|
|
operator to wait for the promise returned by send operation as follows:
|
||
|
|
|
||
|
|
```js
|
||
|
|
// 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.
|
||
|
|
|
||
|
|
#### Promises
|
||
|
|
|
||
|
|
You can also use [Promise chaining](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Using_promises#chaining)
|
||
|
|
to execute send operation.
|
||
|
|
|
||
|
|
```js
|
||
|
|
client.send(command).then(
|
||
|
|
(data) => {
|
||
|
|
// process data.
|
||
|
|
},
|
||
|
|
(error) => {
|
||
|
|
// error handling.
|
||
|
|
}
|
||
|
|
);
|
||
|
|
```
|
||
|
|
|
||
|
|
Promises can also be called using `.catch()` and `.finally()` as follows:
|
||
|
|
|
||
|
|
```js
|
||
|
|
client
|
||
|
|
.send(command)
|
||
|
|
.then((data) => {
|
||
|
|
// process data.
|
||
|
|
})
|
||
|
|
.catch((error) => {
|
||
|
|
// error handling.
|
||
|
|
})
|
||
|
|
.finally(() => {
|
||
|
|
// finally.
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
#### Callbacks
|
||
|
|
|
||
|
|
We do not recommend using callbacks because of [callback hell](http://callbackhell.com/),
|
||
|
|
but they are supported by the send operation.
|
||
|
|
|
||
|
|
```js
|
||
|
|
// callbacks.
|
||
|
|
client.send(command, (err, data) => {
|
||
|
|
// process err and data.
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
#### v2 compatible style
|
||
|
|
|
||
|
|
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](https://aws.amazon.com/blogs/developer/modular-packages-in-aws-sdk-for-javascript/)
|
||
|
|
|
||
|
|
```ts
|
||
|
|
import * as AWS from "@aws-sdk/client-sts";
|
||
|
|
const client = new AWS.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.
|
||
|
|
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).
|
||
|
|
|
||
|
|
```js
|
||
|
|
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;
|
||
|
|
* }
|
||
|
|
*/
|
||
|
|
}
|
||
|
|
```
