@aws-sdk/client-kendra
v3.245.0@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 the 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
Import
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
:
// ES5 example
const { KendraClient, ListIndicesCommand } = require("@aws-sdk/client-kendra");
// ES6+ example
import { KendraClient, ListIndicesCommand } from "@aws-sdk/client-kendra";
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.
// 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:
// 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.
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.
});
Callbacks
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.
});
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
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.
});
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;
* }
*/
}
