## Documentation

Visit [https://bbc.github.io/sqs-producer/](https://bbc.github.io/sqs-producer/) for the full API documentation.

## Usage

```js
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
});
```

### Credentials

By default the consumer will look for AWS credentials in the places [specified by the AWS SDK](https://docs.aws.amazon.com/AWSJavaScriptSDK/guide/node-configuring.html#Setting_AWS_Credentials). The simplest option is to export your credentials as environment variables:

```bash
export AWS_SECRET_ACCESS_KEY=...
export AWS_ACCESS_KEY_ID=...
```

If you need to specify your credentials manually, you can use a pre-configured instance of the [SQS Client](https://docs.aws.amazon.com/AWSJavaScriptSDK/v3/latest/clients/client-sqs/classes/sqsclient.html) client.

```js
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']);
```
