 When the client raises an `Error` that originated at the HTTP layer, like a `ConnectionError` or `TimeoutError`, a `meta` object is often attached to the error object that includes metadata useful for debugging, like request and response information. Because this can include potentially sensitive data, like authentication secrets in an `Authorization` header, the client takes measures to redact common sources of sensitive data when this metadata is attached and serialized.

+
+[discrete]
+==== Breaking changes
+
+[discrete]
+===== Drop support for deprecated `body` parameter
+
+In 8.0, the top-level `body` parameter that was available on all API functions <<remove-body-key,was deprecated>>. In 9.0 this property is completely removed.

+Updated TypeScript types based on fixes and improvements to the Elasticsearch specification.
+
+[discrete]
+===== Drop testing artifacts from npm package
+
+Tap, the unit testing tool used by this project, was recently upgraded and started writing to a `.tap` directory. Since tests are run prior to an `npm publish` in CI, this directory was being included in the published package and bloating its size.
+
+[discrete]
+=== 8.16.1

+==== Fixes
+
+[discrete]
+===== Fix ECMAScript imports

+[discrete]
+===== Support Apache Arrow in ES|QL helper
+
+The ES|QL helper can now return results as an Apache Arrow `Table` or `RecordBatchReader`, which enables high-performance calculations on ES|QL results, even if the response data is larger than the system's available memory. See <<esql-helper>> for more information.
+
+[discrete]
+==== Fixes
+
+[discrete]
+===== Pass prototype poisoning options to serializer correctly
+
+The client's `disablePrototypePoisoningProtection` option was set to `true` by default, but when it was set to any other value it was ignored, making it impossible to enable prototype poisoning protection without providing a custom serializer implementation.
+

+===== ES|QL object API helper
+
+A helper method has been added that parses the response of an ES|QL query and converts it into an array of objects.
+A TypeScript type parameter can also be provided to improve developer experience when working with the result. https://github.com/elastic/elasticsearch-js/pull/2238[#2238]
+
+[discrete]
+===== `onSuccess` callback added to bulk helper

+
+[discrete]
+===== Request retries are more polite
+
+https://github.com/elastic/elastic-transport-js/releases/tag/v8.6.0[`@elastic/transport` v8.6.0] was released, which refactored when and how failed requests are retried. Timed-out requests are no longer retried by default, and retries now use exponential backoff rather than running immediately.

+
+`@elastic/transport` https://github.com/elastic/elastic-transport-js/releases/tag/v8.4.0[version 8.4.0] introduces enhanced measures for ensuring that request metadata attached to some `Error` objects is redacted. This functionality is primarily to address custom logging solutions that don't use common serialization methods like `JSON.stringify`, `console.log`, or `util.inspect`, which were already accounted for.

+Maintaining both API styles is not a problem per se, but it makes error handling more convoluted due to async stack traces.
+Moving to a full-promise API will solve this issue.
+
+[source,js]
+----
+// callback-style api
+client.search({ params }, { options }, (err, result) => {
+ console.log(err || result)
+})
+
+// promise-style api
+client.search({ params }, { options })
+  .then(console.log)
+  .catch(console.log)
+
+// async-style (sugar syntax on top of promises)
+const response = await client.search({ params }, { options })
+console.log(response)
+----
+
+If you are already using the promise-style API, this won't be a breaking change for you.
+
+[discrete]
+===== Remove the current abort API and use the new AbortController standard
+
+*Breaking: Yes* | *Migration effort: Small*
+
+The old abort API makes sense for callbacks but it's annoying to use with promises
+
+[source,js]
+----
+// callback-style api
+const request = client.search({ params }, { options }, (err, result) => {
+ console.log(err) // RequestAbortedError
+})
+
+request.abort()
+
+// promise-style api
+const promise = client.search({ params }, { options })
+
+promise
+  .then(console.log)
+  .catch(console.log) // RequestAbortedError
+
+promise.abort()
+----
+
+Node v12 has added the standard https://nodejs.org/api/globals.html#globals_class_abortcontroller[`AbortController`] API which is designed to work well with both callbacks and promises.
+[source,js]
+----
+const ac = new AbortController()
+client.search({ params }, { signal: ac.signal })
+  .then(console.log)
+  .catch(console.log) // RequestAbortedError
+
+ac.abort()

+[[remove-body-key]]
+===== Remove the body key from the request
+
+*Breaking: Yes* | *Migration effort: Small*
+
+Thanks to the new types we are developing now we know exactly where a parameter should go.
+The client API leaks HTTP-related notions in many places, and removing them would definitely improve the DX.
+
+This could be a rather big breaking change, so a double solution could be used during the 8.x lifecycle. (accepting body keys without them being wrapped in the body as well as the current solution).
+
+To convert code from 7.x, you need to remove the `body` parameter in all the endpoints request.
+For instance, this is an example for the `search` endpoint:
+
+[source,js]
+----
+// from
+const response = await client.search({
+  index: 'test',
+  body: {
+    query: {
+      match_all: {}
+    }
+  }
+})
+
+// to
+const response = await client.search({
+  index: 'test',
+  query: {
+    match_all: {}
+  }
+})
+----
+
+[discrete]
+===== Migrate to new separate transport
+
+*Breaking: Yes* | *Migration effort: Small to none*
+
+The separated transport has been rewritten in TypeScript and has already dropped the callback style API.
+Given that now is separated, most of the Elasticsearch specific concepts have been removed, and the client will likely need to extend parts of it for reintroducing them.
+If you weren't extending the internals of the client, this won't be a breaking change for you.
+
+[discrete]
+===== The returned value of API calls is the body and not the HTTP related keys
+
+*Breaking: Yes* | *Migration effort: Small*
+
+The client API leaks HTTP-related notions in many places, and removing them would definitely improve the DX.
+The client will expose a new request-specific option to still get the full response details.
+
+The new behaviour returns the `body` value directly as response.
+If you want to have the 7.x response format, you need to add `meta : true` in the request.
+This will return all the HTTP meta information, including the `body`.
+
+For instance, this is an example for the `search` endpoint:
+
+[source,js]
+----
+// from
+const response = await client.search({
+  index: 'test',
+  body: {
+    query: {
+      match_all: {}
+    }
+  }
+})
+console.log(response) // { body: SearchResponse, statusCode: number, headers: object, warnings: array }
+
+// to
+const response = await client.search({
+  index: 'test',
+  query: {
+    match_all: {}
+  }
+})
+console.log(response) // SearchResponse
+
+// with a bit of TypeScript and JavaScript magic...
+const response = await client.search({
+  index: 'test',
+  query: {
+    match_all: {}
+  }
+}, {
+  meta: true
+})
+console.log(response) // { body: SearchResponse, statusCode: number, headers: object, warnings: array }

+[discrete]
+===== Use a weighted connection pool
+
+*Breaking: Yes* | *Migration effort: Small to none*
+
+Move from the current cluster connection pool to a weight-based implementation.
+This new implementation offers better performances and runs less code in the background, the old connection pool can still be used.
+If you weren't extending the internals of the client, this won't be a breaking change for you.
+
+[discrete]
+===== Migrate to the "undici" http client
+
+*Breaking: Yes* | *Migration effort: Small to none*
+
+By default, the HTTP client will no longer be the default Node.js HTTP client, but https://github.com/nodejs/undici[undici] instead.
+Undici is a brand new HTTP client written from scratch, it offers vastly improved performances and has better support for promises.
+Furthermore, it offers comprehensive and predictable error handling. The old HTTP client can still be used.
+If you weren't extending the internals of the client, this won't be a breaking change for you.
+
+[discrete]
+===== Drop support for old camelCased keys
+
+*Breaking: Yes* | *Migration effort: Medium*
+
+Currently, every path or query parameter could be expressed in both `snake_case` and `camelCase`. Internally the client will convert everything to `snake_case`.
+This was done in an effort to reduce the friction of migrating from the legacy to the new client, but now it no longer makes sense.
+If you are already using `snake_case` keys, this won't be a breaking change for you.
+
+[discrete]
+===== Rename `ssl` option to `tls`
+
+*Breaking: Yes* | *Migration effort: Small*
+
+People usually refers to this as `tls`, furthermore, internally we use the tls API and Node.js refers to it as tls everywhere.
+[source,js]
+----
+// before
+const client = new Client({
+  node: 'https://localhost:9200',
+  ssl: {
+    rejectUnauthorized: false
+  }
+})
+
+// after
+const client = new Client({
+  node: 'https://localhost:9200',
+  tls: {
+    rejectUnauthorized: false
+  }
+})
+----
+
+[discrete]
+===== Remove prototype poisoning protection
+
+*Breaking: Yes* | *Migration effort: Small*
+
+Prototype poisoning protection is very useful, but it can cause performances issues with big payloads.
+In v8 it will be removed, and the documentation will show how to add it back with a custom serializer.
+
+[discrete]
+===== Remove client extensions API
+
+*Breaking: Yes* | *Migration effort: Large*
+
+Nowadays the client support the entire Elasticsearch API, and the `transport.request` method can be used if necessary. The client extensions API have no reason to exist.
+[source,js]
+----
+client.extend('utility.index', ({ makeRequest }) => {
+  return function _index (params, options) {
+    // your code
+  }
+})
+
+client.utility.index(...)
+----
+
+If you weren't using client extensions, this won't be a breaking change for you.
+
+[discrete]
+===== Move to TypeScript
+
+*Breaking: No* | *Migration effort: None*
+
+The new separated transport is already written in TypeScript, and it makes sense that the client v8 will be fully written in TypeScript as well.
+
+[discrete]
+===== Move from emitter-like interface to a diagnostic method
+
+*Breaking: Yes* | *Migration effort: Small*
+
+Currently, the client offers a subset of methods of the `EventEmitter` class, v8 will ship with a `diagnostic` property which will be a proper event emitter.
+[source,js]
+----
+// from
+client.on('request', console.log)
+
+// to
+client.diagnostic.on('request', console.log)
+----
+
+[discrete]
+===== Remove username & password properties from Cloud configuration
+
+*Breaking: Yes* | *Migration effort: Small*
+
+The Cloud configuration does not support ApiKey and Bearer auth, while the `auth` options does.
+There is no need to keep the legacy basic auth support in the cloud configuration.
+[source,js]
+----
+// before
+const client = new Client({
+  cloud: {
+    id: '<cloud-id>',
+    username: 'elastic',
+    password: 'changeme'
+  }
+})
+
+// after
+const client = new Client({
+  cloud: {
+    id: '<cloud-id>'
+  },
+  auth: {
+    username: 'elastic',
+    password: 'changeme'
+  }
+})
+----
+
+If you are already passing the basic auth options in the `auth` configuration, this won't be a breaking change for you.
+
+[discrete]
+===== Calling `client.close` will reject new requests
+
+Once you call `client.close` every new request after that will be rejected with a `NoLivingConnectionsError`. In-flight requests will be executed normally unless an in-flight request requires a retry, in which case it will be rejected.
+
+[discrete]
+===== Parameters rename
+
+- `ilm.delete_lifecycle`: `policy` parameter has been renamed to `name`
+- `ilm.get_lifecycle`: `policy` parameter has been renamed to `name`
+- `ilm.put_lifecycle`: `policy` parameter has been renamed to `name`
+- `snapshot.cleanup_repository`: `repository` parameter has been renamed to `name`
+- `snapshot.create_repository`: `repository` parameter has been renamed to `name`
+- `snapshot.delete_repository`: `repository` parameter has been renamed to `name`
+- `snapshot.get_repository`: `repository` parameter has been renamed to `name`
+- `snapshot.verify_repository`: `repository` parameter has been renamed to `name`
+
+[discrete]
+===== Removal of snake_cased methods
+
+The v7 client provided snake_cased methods, such as `client.delete_by_query`. This is no longer supported, now only camelCased method are present.
+So `client.delete_by_query` can be accessed with `client.deleteByQuery`

+[[child]]
+=== Creating a child client
+
+There are some use cases where you may need multiple instances of the client. 
+You can easily do that by calling `new Client()` as many times as you need, but 
+you will lose all the benefits of using one single client, such as the long 
+living connections and the connection pool handling. To avoid this problem, the 
+client offers a `child` API, which returns a new client instance that shares the 
+connection pool with the parent client.
+
+NOTE: The event emitter is shared between the parent and the child(ren). If you 
+extend the parent client, the child client will have the same extensions, while 
+if the child client adds an extension, the parent client will not be extended.
+
+You can pass to the `child` every client option you would pass to a normal 
+client, but the connection pool specific options (`ssl`, `agent`, `pingTimeout`, 
+`Connection`, and `resurrectStrategy`).
+
+CAUTION: If you call `close` in any of the parent/child clients, every client 
+will be closed.

+[[auth-ec]]
+==== Elastic Cloud
+
+If you are using https://www.elastic.co/cloud[Elastic Cloud], the client offers
+an easy way to connect to it via the `cloud` option. You must pass the Cloud ID
+that you can find in the cloud console, then your username and password inside
+the `auth` option.
+
+NOTE: When connecting to Elastic Cloud, the client will automatically enable
+both request and response compression by default, since it yields significant
+throughput improvements. Moreover, the client will also set the tls option
+`secureProtocol` to `TLSv1_2_method` unless specified otherwise. You can still
+override this option by configuring them.
+
+IMPORTANT: Do not enable sniffing when using Elastic Cloud, since the nodes are
+behind a load balancer, Elastic Cloud will take care of everything for you.
+Take a look https://www.elastic.co/blog/elasticsearch-sniffing-best-practices-what-when-why-how[here]
+to know more.

+[[connect-self-managed-new]]
+=== Connecting to a self-managed cluster
+
+By default {es} will start with security features like authentication and TLS
+enabled. To connect to the {es} cluster you'll need to configure the Node.js {es}
+client to use HTTPS with the generated CA certificate in order to make requests
+successfully.
+
+If you're just getting started with {es} we recommend reading the documentation
+on https://www.elastic.co/guide/en/elasticsearch/reference/current/settings.html[configuring]
+and
+https://www.elastic.co/guide/en/elasticsearch/reference/current/starting-elasticsearch.html[starting {es}]
+to ensure your cluster is running as expected.
+
+When you start {es} for the first time you'll see a distinct block like the one
+below in the output from {es} (you may have to scroll up if it's been a while):
+
+[source,sh]
+----
+
+-> Elasticsearch security features have been automatically configured!
+-> Authentication is enabled and cluster connections are encrypted.

+...
+
+----
+
+Depending on the circumstances there are two options for verifying the HTTPS
+connection, either verifying with the CA certificate itself or via the HTTP CA
+certificate fingerprint.
+
+[discrete]
+[[auth-tls]]
+==== TLS configuration
+
+The generated root CA certificate can be found in the `certs` directory in your
+{es} config location (`$ES_CONF_PATH/certs/http_ca.crt`). If you're running {es}
+in Docker there is
+https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html[additional documentation for retrieving the CA certificate].
+
+Without any additional configuration you can specify `https://` node urls, and
+the certificates used to sign these requests will be verified. To turn off
+certificate verification, you must specify an `tls` object in the top level
+config and set `rejectUnauthorized: false`. The default `tls` values are the
+same that Node.js's https://nodejs.org/api/tls.html#tls_tls_connect_options_callback[`tls.connect()`]
+uses.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://localhost:9200',
+  auth: {
+    username: 'elastic',
+    password: 'changeme'
+  },
+  tls: {
+    ca: fs.readFileSync('./http_ca.crt'),
+    rejectUnauthorized: false
+  }
+})
+----
+
+[discrete]
+[[auth-ca-fingerprint]]
+==== CA fingerprint
+
+You can configure the client to only trust certificates that are signed by a specific CA certificate
+(CA certificate pinning) by providing a `caFingerprint` option.
+This will verify that the fingerprint of the CA certificate that has signed
+the certificate of the server matches the supplied value.
+You must configure a SHA256 digest.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://example.com'
+  auth: { ... },
+  // the fingerprint (SHA256) of the CA certificate that is used to sign
+  // the certificate that the Elasticsearch node presents for TLS.
+  caFingerprint: '20:0D:CA:FA:76:...',
+  tls: {
+    // might be required if it's a self-signed certificate
+    rejectUnauthorized: false
+  }
+})
+----
+
+The certificate fingerprint can be calculated using `openssl x509` with the
+certificate file:
+
+[source,sh]
+----
+openssl x509 -fingerprint -sha256 -noout -in /path/to/http_ca.crt
+----
+
+If you don't have access to the generated CA file from {es} you can use the
+following script to output the root CA fingerprint of the {es} instance with
+`openssl s_client`:
+
+[source,sh]
+----
+# Replace the values of 'localhost' and '9200' to the
+# corresponding host and port values for the cluster.
+openssl s_client -connect localhost:9200 -servername localhost -showcerts </dev/null 2>/dev/null \
+  | openssl x509 -fingerprint -sha256 -noout -in /dev/stdin
+----
+
+The output of `openssl x509` will look something like this:
+
+[source,sh]
+----
+SHA256 Fingerprint=A5:2D:D9:35:11:E8:C6:04:5E:21:F1:66:54:B7:7C:9E:E0:F3:4A:EA:26:D9:F4:03:20:B5:31:C4:74:67:62:28

+WARNING: Running {es} without security enabled is not recommended.
+
+If your cluster is configured with

+[[auth-apikey]]
+==== ApiKey authentication
+
+You can use the
+{ref-7x}/security-api-create-api-key.html[ApiKey]
+authentication by passing the `apiKey` parameter via the `auth` option. The
+`apiKey` parameter can be either a base64 encoded string or an object with the
+values that you can obtain from the
+{ref-7x}/security-api-create-api-key.html[create api key endpoint].
+
+NOTE: If you provide both basic authentication credentials and the ApiKey
+configuration, the ApiKey takes precedence.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://localhost:9200',
+  auth: {
+    apiKey: 'base64EncodedKey'
+  }

+  auth: {
+    apiKey: {
+      id: 'foo',
+      api_key: 'bar'
+    }
+  }
+})
+----
+
+[discrete]
+[[auth-bearer]]
+==== Bearer authentication
+
+You can provide your credentials by passing the `bearer` token
+parameter via the `auth` option.
+Useful for https://www.elastic.co/guide/en/elasticsearch/reference/current/security-api-create-service-token.html[service account tokens].
+Be aware that it does not handle automatic token refresh.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://localhost:9200',
+  auth: {
+    bearer: 'token'
+  }
+})
+----
+
+
+[discrete]
+[[auth-basic]]
+==== Basic authentication
+
+You can provide your credentials by passing the `username` and `password`
+parameters via the `auth` option.
+
+NOTE: If you provide both basic authentication credentials and the Api Key
+configuration, the Api Key will take precedence.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://localhost:9200',
+  auth: {
+    username: 'elastic',
+    password: 'changeme'
+  }
+})
+----
+
+
+Otherwise, you can provide your credentials in the node(s) URL.
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  node: 'https://username:password@localhost:9200'
+})
+----
+
+
+[discrete]
+[[client-usage]]
+=== Usage
+
+Using the client is straightforward, it supports all the public APIs of {es},
+and every method exposes the same signature.
+
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  cloud: { id: '<cloud-id>' },
+  auth: { apiKey: 'base64EncodedKey' }
+})
+
+const result = await client.search({
+  index: 'my-index',
+  query: {
+    match: { hello: 'world' }
+  }
+})
+----
+
+The returned value of every API call is the response body from {es}.
+If you need to access additonal metadata, such as the status code or headers,
+you must specify `meta: true` in the request options:
+
+[source,js]
+----
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  cloud: { id: '<cloud-id>' },
+  auth: { apiKey: 'base64EncodedKey' }
+})
+
+const result = await client.search({
+  index: 'my-index',
+  query: {
+    match: { hello: 'world' }
+  }
+}, { meta: true })
+----
+
+In this case, the result will be:
+[source,ts]
+----
+{
+  body: object | boolean
+  statusCode: number
+  headers: object
+  warnings: string[],
+  meta: object
+}
+----
+
+NOTE: The body is a boolean value when you use `HEAD` APIs.
+
+[discrete]
+==== Aborting a request
+
+If needed, you can abort a running request by using the `AbortController` standard.
+
+CAUTION: If you abort a request, the request will fail with a
+`RequestAbortedError`.
+
+
+[source,js]
+----
+const AbortController = require('node-abort-controller')
+const { Client } = require('@elastic/elasticsearch')
+const client = new Client({
+  cloud: { id: '<cloud-id>' },
+  auth: { apiKey: 'base64EncodedKey' }
+})
+
+const abortController = new AbortController()
+setImmediate(() => abortController.abort())
+
+const result = await client.search({
+  index: 'my-index',
+  query: {
+    match: { hello: 'world' }
+  }
+}, { signal: abortController.signal })
+----
+
+[discrete]
+==== Request specific options
+
+If needed you can pass request specific options in a second object:
+
+[source,js]
+----
+const result = await client.search({
+  index: 'my-index',
+  body: {
+    query: {
+      match: { hello: 'world' }
+    }
+  }
+}, {
+  ignore: [404],
+  maxRetries: 3
+})
+----
+
+
+The supported request specific options are:
+[cols=2*]
+|===
+|`ignore`
+|`number[]` -  HTTP status codes which should not be considered errors for this request. +
+_Default:_ `null`
+
+|`requestTimeout`
+|`number | string` - Max request timeout for the request in milliseconds, it overrides the client default. +
+_Default:_ `30000`
+
+|`retryOnTimeout`
+|`boolean` - Retry requests that have timed out.
+_Default:_ `false`
+
+|`maxRetries`
+|`number` - Max number of retries for the request, it overrides the client default. +
+_Default:_ `3`
+
+|`compression`
+|`string | boolean` - Enables body compression for the request. +
+_Options:_ `false`, `'gzip'` +
+_Default:_ `false`
+
+|`asStream`
+|`boolean` - Instead of getting the parsed body back, you get the raw Node.js stream of data. +
+_Default:_ `false`
+
+|`headers`
+|`object` - Custom headers for the request. +

+=== Using the Client in a Function-as-a-Service Environment
+
+This section illustrates the best practices for leveraging the {es} client in a Function-as-a-Service (FaaS) environment.
+The most influential optimization is to initialize the client outside of the function, the global scope.
+This practice does not only improve performance but also enables background functionality as – for example – https://www.elastic.co/blog/elasticsearch-sniffing-best-practices-what-when-why-how[sniffing].
+The following examples provide a skeleton for the best practices.

+[[client-connect-proxy]]
+=== Connecting through a proxy
+
+~Added~ ~in~ ~`v7.10.0`~
+
+If you need to pass through an http(s) proxy for connecting to {es}, the client
+out of the box offers a handy configuration for helping you with it. Under the
+hood, it uses the https://github.com/delvedor/hpagent[`hpagent`] module.
+
+IMPORTANT: In versions 8.0+ of the client, the default `Connection` type is set to `UndiciConnection`, which does not support proxy configurations.
+To use a proxy, you will need to use the `HttpConnection` class from `@elastic/transport` instead.
+
+[source,js]
+----
+import { HttpConnection } from '@elastic/transport'
+
+const client = new Client({
+  node: 'http://localhost:9200',
+  proxy: 'http://localhost:8080',
+  Connection: HttpConnection,
+})
+----
+
+Basic authentication is supported as well:
+
+[source,js]
+----
+const client = new Client({
+  node: 'http://localhost:9200',
+  proxy: 'http:user:pwd@//localhost:8080',
+  Connection: HttpConnection,
+})
+----
+
+If you are connecting through a non-http(s) proxy, such as a `socks5` or `pac`,
+you can use the `agent` option to configure it.
+
+[source,js]
+----
+const SocksProxyAgent = require('socks-proxy-agent')
+const client = new Client({
+  node: 'http://localhost:9200',
+  agent () {
+    return new SocksProxyAgent('socks://127.0.0.1:1080')
+  },
+  Connection: HttpConnection,
+})
+----
+
+
+[discrete]
+[[client-error-handling]]
+=== Error handling
+
+The client exposes a variety of error objects that you can use to enhance your
+error handling. You can find all the error objects inside the `errors` key in
+the client.
+
+[source,js]
+----
+const { errors } = require('@elastic/elasticsearch')
+console.log(errors)
+----
+
+
+You can find the errors exported by the client in the table below.
+
+[cols=3*]
+|===
+|*Error*
+|*Description*
+|*Properties*
+
+|`ElasticsearchClientError`
+|Every error inherits from this class, it is the basic error generated by the client.
+a|* `name` - `string`
+* `message` - `string`
+
+|`TimeoutError`
+|Generated when a request exceeds the `requestTimeout` option.
+a|* `name` - `string`
+* `message` - `string`
+* `meta` - `object`, contains all the information about the request
+
+|`ConnectionError`
+|Generated when an error occurs during the request, it can be a connection error or a malformed stream of data.
+a|* `name` - `string`
+* `message` - `string`
+* `meta` - `object`, contains all the information about the request
+
+|`RequestAbortedError`
+|Generated if the user calls the `request.abort()` method.
+a|* `name` - `string`
+* `message` - `string`
+* `meta` - `object`, contains all the information about the request
+
+|`NoLivingConnectionsError`
+|Given the configuration, the ConnectionPool was not able to find a usable Connection for this request.
+a|* `name` - `string`
+* `message` - `string`
+* `meta` - `object`, contains all the information about the request
+
+|`SerializationError`
+|Generated if the serialization fails.
+a|* `name` - `string`
+* `message` - `string`
+* `data` - `object`, the object to serialize
+
+|`DeserializationError`
+|Generated if the deserialization fails.
+a|* `name` - `string`
+* `message` - `string`
+* `data` - `string`, the string to deserialize
+
+|`ConfigurationError`
+|Generated if there is a malformed configuration or parameter.
+a|* `name` - `string`
+* `message` - `string`
+
+|`ResponseError`
+|Generated when in case of a `4xx` or `5xx` response.
+a|* `name` - `string`
+* `message` - `string`
+* `meta` - `object`, contains all the information about the request
+* `body` - `object`, the response body
+* `statusCode` - `object`, the response headers
+* `headers` - `object`, the response status code
+|===
+
+[[keep-alive]]
+[discrete]
+=== Keep-alive connections
+
+By default, the client uses persistent, keep-alive connections to reduce the overhead of creating a new HTTP connection for each Elasticsearch request.
+If you are using the default `UndiciConnection` connection class, it maintains a pool of 256 connections with a keep-alive of 10 minutes.
+If you are using the legacy `HttpConnection` connection class, it maintains a pool of 256 connections with a keep-alive of 1 minute.
+
+If you need to disable keep-alive connections, you can override the HTTP agent with your preferred https://nodejs.org/api/http.html#http_new_agent_options[HTTP agent options]:
+
+[source,js]
+----
+const client = new Client({
+  node: 'http://localhost:9200',
+  // the function takes as parameter the option
+  // object passed to the Connection constructor
+  agent: (opts) => new CustomAgent()
+})
+----
+
+Or you can disable the HTTP agent entirely:
+
+[source,js]
+----
+const client = new Client({
+  node: 'http://localhost:9200',
+  // Disable agent and keep-alive
+  agent: false
+})
+----
+
+[discrete]
+[[close-connections]]
+=== Closing a client's connections
+
+If you would like to close all open connections being managed by an instance of the client, use the `close()` function:
+
+[source,js]
+----
+const client = new Client({
+  node: 'http://localhost:9200'
+});
+client.close();
+----
+
+[discrete]
+[[product-check]]
+=== Automatic product check
+
+Since v7.14.0, the client performs a required product check before the first call.
+This pre-flight product check allows the client to establish the version of Elasticsearch
+that it is communicating with. The product check requires one additional HTTP request to
+be sent to the server as part of the request pipeline before the main API call is sent.
+In most cases, this will succeed during the very first API call that the client sends.
+Once the product check completes, no further product check HTTP requests are sent for
+subsequent API calls.
