AWS SDK for JavaScript IoTJobsDataPlane Client for Node.js, Browser and React Native.
IoT Jobs is a service that allows you to define a set of jobs — remote operations that are sent to and executed on one or more devices connected to Amazon Web Services IoT Core. For example, you can define a job that instructs a set of devices to download and install application or firmware updates, reboot, rotate certificates, or perform remote troubleshooting operations.
Find the endpoint address for actions in the IoT jobs data plane by running this CLI command:
aws iot describe-endpoint --endpoint-type iot:Jobs
The service name used by Amazon Web Services Signature Version 4 to sign requests is: iot-jobs-data.
To create a job, you make a job document which is a description of the remote operations to be performed, and you specify a list of targets that should perform the operations. The targets can be individual things, thing groups or both.
IoT Jobs sends a message to inform the targets that a job is available. The target starts the execution of the job by downloading the job document, performing the operations it specifies, and reporting its progress to Amazon Web Services IoT Core. The Jobs service provides commands to track the progress of a job on a specific target and for all the targets of the job
To install this package, simply type add or install @aws-sdk/client-iot-jobs-data-plane using your favorite package manager:
npm install @aws-sdk/client-iot-jobs-data-planeyarn add @aws-sdk/client-iot-jobs-data-planepnpm add @aws-sdk/client-iot-jobs-data-plane
The AWS SDK is modulized by clients and commands.
To send a request, you only need to import the IoTJobsDataPlaneClient and
the commands you need, for example GetPendingJobExecutionsCommand:
// ES5 example
const { IoTJobsDataPlaneClient, GetPendingJobExecutionsCommand } = require("@aws-sdk/client-iot-jobs-data-plane");// ES6+ example
import { IoTJobsDataPlaneClient, GetPendingJobExecutionsCommand } from "@aws-sdk/client-iot-jobs-data-plane";To send a request, you:
- Initiate client with configuration (e.g. credentials, region).
- Initiate command with input parameters.
- Call
sendoperation 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 IoTJobsDataPlaneClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new GetPendingJobExecutionsCommand(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-iot-jobs-data-plane";
const client = new AWS.IoTJobsDataPlane({ region: "REGION" });
// async/await.
try {
const data = await client.getPendingJobExecutions(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.getPendingJobExecutions(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.getPendingJobExecutions(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;
* }
