@aws-sdk/client-notifications

Description

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

The User Notifications API Reference provides descriptions, API request parameters, and the JSON response for each of the User Notifications API actions.

User Notification control plane APIs are currently available in US East (Virginia) - us-east-1.

GetNotificationEvent and ListNotificationEvents APIs are currently available in commercial partition Regions and only return notifications stored in the same Region in which they're called.

The User Notifications console can only be used in US East (Virginia). Your data however, is stored in each Region chosen as a notification hub in addition to US East (Virginia).

For information about descriptions, API request parameters, and the JSON response for email contact related API actions, see the User Notifications Contacts API Reference Guide.

Installing

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

Getting Started

$3

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

``js // ES5 example const { NotificationsClient, ListChannelsCommand } = require("@aws-sdk/client-notifications");`

`ts // ES6+ example import { NotificationsClient, ListChannelsCommand } from "@aws-sdk/client-notifications";`

`$3`

To send a request, you:

- Initiate client with configuration (e.g. credentials, region). - Initiate command with input parameters. - Callsendoperation on client with command object as input. - If you are using a custom http handler, you may calldestroy() to close open connections.

`js // a client can be shared by different commands. const client = new NotificationsClient({ region: "REGION" });

const params = { /* input parameters / }; const command = new ListChannelsCommand(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-notifications"; const client = new AWS.Notifications({ region: "REGION" });

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

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

// callbacks. client.listChannels(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; * } */ }`
