AWS SDK for JavaScript Application Insights Client for Node.js, Browser and React Native
npm install @aws-sdk/client-application-insightsAWS SDK for JavaScript ApplicationInsights Client for Node.js, Browser and React Native.
Amazon CloudWatch Application Insights is a service that helps you detect common
problems with your applications. It enables you to pinpoint the source of issues in your
applications (built with technologies such as Microsoft IIS, .NET, and Microsoft SQL
Server), by providing key insights into detected problems.
After you onboard your application, CloudWatch Application Insights identifies,
recommends, and sets up metrics and logs. It continuously analyzes and correlates your
metrics and logs for unusual behavior to surface actionable problems with your application.
For example, if your application is slow and unresponsive and leading to HTTP 500 errors in
your Application Load Balancer (ALB), Application Insights informs you that a memory
pressure problem with your SQL Server database is occurring. It bases this analysis on
impactful metrics and log errors.
npm install @aws-sdk/client-application-insightsyarn add @aws-sdk/client-application-insightspnpm add @aws-sdk/client-application-insightsThe AWS SDK is modulized by clients and commands.
To send a request, you only need to import the ApplicationInsightsClient and
the commands you need, for example ListApplicationsCommand:
``js`
// ES5 example
const { ApplicationInsightsClient, ListApplicationsCommand } = require("@aws-sdk/client-application-insights");
`ts`
// ES6+ example
import { ApplicationInsightsClient, ListApplicationsCommand } from "@aws-sdk/client-application-insights";
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.destroy()
- If you are using a custom http handler, you may call to close open connections.
`js
// a client can be shared by different commands.
const client = new ApplicationInsightsClient({ region: "REGION" });
const params = { /* input parameters / };
const command = new ListApplicationsCommand(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-application-insights";
const client = new AWS.ApplicationInsights({ region: "REGION" });
// async/await.
try {
const data = await client.listApplications(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.listApplications(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.listApplications(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).
`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;
* }
*/
}
