### Create and Use Basic SQS Producer

Source: https://github.com/bbc/sqs-producer/blob/main/README.md

Create a simple SQS producer and send messages. Requires importing Producer and SQSClient. Ensure AWS credentials are configured.

```javascript
import { Producer } from "sqs-producer";
import { SQSClient } from "@aws-sdk/client-sqs";

// create simple producer
const producer = Producer.create({
  queueUrl: "https://sqs.eu-west-1.amazonaws.com/account-id/queue-name",
  region: "eu-west-1",
});

// send messages to the queue
await producer.send(["msg1", "msg2"]);

// get the current size of the queue
const size = await producer.queueSize();
console.log(`There are ${size} messages on the queue.`);

// send a message to the queue with a specific ID (by default the body is used as the ID)
await producer.send([
  {
    id: "id1",
    body: "Hello world",
  },
]);

// send a message to the queue with
// - delaySeconds (must be an number contained within 0 and 900)
// - messageAttributes
await producer.send([
  {
    id: "id1",
    body: "Hello world with two string attributes: attr1 and attr2",
    messageAttributes: {
      attr1: { DataType: "String", StringValue: "stringValue" },
      attr2: { DataType: "Binary", BinaryValue: new Buffer("binaryValue") },
    },
  },
  {
    id: "id2",
    body: "Hello world delayed by 5 seconds",
    delaySeconds: 5,
  },
]);

// send a message to a FIFO queue
//
// note that AWS FIFO queues require two additional params:
// - groupId (string)
// - deduplicationId (string)
//
// deduplicationId can be excluded if content-based deduplication is enabled
//
// https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/FIFO-queue-recommendations.html
await producer.send({
  id: "testId",
  body: "Hello world from our FIFO queue!",
  groupId: "group1234",
  deduplicationId: "abcdef123456", // typically a hash of the message body
});

// send messages to a standard queue with groupId for fair queue behavior
//
// Fair queues automatically mitigate noisy neighbor impact in multi-tenant queues
// by using groupId to identify tenants and ensure fair resource allocation
//
// https://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/sqs-fair-queues.html
await producer.send([
  {
    id: "msg1",
    body: "Message from tenant A",
    groupId: "tenant-a",
  },
  {
    id: "msg2",
    body: "Message from tenant B",
    groupId: "tenant-b",
  },
]);
```

--------------------------------

### Run SQS Producer Tests

Source: https://github.com/bbc/sqs-producer/blob/main/README.md

Execute the test suite for the sqs-producer package using npm.

```bash
npm test
```

--------------------------------

### Configure SQS Producer with Custom SQS Client

Source: https://github.com/bbc/sqs-producer/blob/main/README.md

Create an SQS producer with a pre-configured SQS client, allowing manual specification of credentials and region. This is an alternative to using environment variables for AWS credentials.

```javascript
import { Producer } from "sqs-producer";
import { SQSClient } from "@aws-sdk/client-sqs";

// create simple producer
const producer = Producer.create({
  queueUrl: "https://sqs.eu-west-1.amazonaws.com/account-id/queue-name",
  region: "eu-west-1",
  sqs: new SQSClient({
    region: "my-region",
    credentials: {
      accessKeyId: "yourAccessKey",
      secretAccessKey: "yourSecret",
    },
  }),
});

// send messages to the queue
await producer.send(["msg1", "msg2"]);
```

--------------------------------

### Generate SQS Producer Coverage Report

Source: https://github.com/bbc/sqs-producer/blob/main/README.md

Generate a code coverage report for the sqs-producer package by running the specified npm command.

```bash
npm run coverage
```

--------------------------------

### Lint SQS Producer Code

Source: https://github.com/bbc/sqs-producer/blob/main/README.md

Check the sqs-producer code for potential problems using ESLint with the provided npm command.

```bash
npm run lint
```
