AWS SDK for JavaScript Opensearchserverless Client for Node.js, Browser and React Native
AWS SDK for JavaScript OpenSearchServerless Client for Node.js, Browser and React Native.
Use the Amazon OpenSearch Serverless API to create, configure, and manage OpenSearch Serverless collections and security policies.
OpenSearch Serverless is an on-demand, pre-provisioned serverless configuration for Amazon OpenSearch Service. OpenSearch Serverless removes the operational complexities of provisioning, configuring, and tuning your OpenSearch clusters. It enables you to easily search and analyze petabytes of data without having to worry about the underlying infrastructure and data management.
To learn more about OpenSearch Serverless, see What is Amazon OpenSearch Serverless?
To install this package, simply type add or install @aws-sdk/client-opensearchserverless using your favorite package manager:
npm install @aws-sdk/client-opensearchserverlessyarn add @aws-sdk/client-opensearchserverlesspnpm add @aws-sdk/client-opensearchserverlessThe AWS SDK is modulized by clients and commands.
To send a request, you only need to import the OpenSearchServerlessClient and
the commands you need, for example ListCollectionsCommand:
// ES5 example
const { OpenSearchServerlessClient, ListCollectionsCommand } = require("@aws-sdk/client-opensearchserverless");
// ES6+ example
import { OpenSearchServerlessClient, ListCollectionsCommand } from "@aws-sdk/client-opensearchserverless";
To send a request, you:
send operation on client with command object as input.destroy() to close open connections.// a client can be shared by different commands.
const client = new OpenSearchServerlessClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new ListCollectionsCommand(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-opensearchserverless";
const client = new AWS.OpenSearchServerless({ region: "REGION" });
// async/await.
try {
const data = await client.listCollections(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.listCollections(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.listCollections(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;
* }
*/
}
