@aws-sdk/client-kendra

Description

AWS SDK for JavaScript Kendra Client for Node.js, Browser and React Native.

Amazon Kendra is a service for indexing large document sets.

Installing

To install this package, simply type add or install @aws-sdk/client-kendra
using your favorite package manager:
- npm install @aws-sdk/client-kendra
- yarn add @aws-sdk/client-kendra
- pnpm add @aws-sdk/client-kendra

Getting Started

$3

The AWS SDK is modulized by clients and commands.
To send a request, you only need to import the KendraClient and
the commands you need, for example ListIndicesCommand:

``js
// ES5 example
const { KendraClient, ListIndicesCommand } = require("@aws-sdk/client-kendra");
`

`ts
// ES6+ example
import { KendraClient, ListIndicesCommand } from "@aws-sdk/client-kendra";
`

$3

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 KendraClient({ region: "REGION" });

const params = { /* input parameters / };
const command = new ListIndicesCommand(params);
`

#### Async/await

We recommend using 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
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,
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

`ts
import * as AWS from "@aws-sdk/client-kendra";
const client = new AWS.Kendra({ region: "REGION" });

// async/await.
try {
const data = await client.listIndices(params);
// process data.
} catch (error) {
// error handling.
}

// Promises.
client
.listIndices(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});

// callbacks.
client.listIndices(params, (err, data) => {
// process err and data.
});
`

$3

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;
* }
*/
}
`
