lambda-powertools-dynamodb-client

DynamoDB client wrapper that knows how to forward correlation IDs (captured via @dazn/lambda-powertools-correlation-ids).

Main features:

* auto-injects correlation IDs into the DynamoDB item(s) so they are available in the DynamoDB Stream

* direct replacement for AWS.DynamoDB.Document client

Getting Started

Install from NPM: npm install @dazn/lambda-powertools-dynamodb-client

API

It's exactly the same as the DynamoDB Document client from the AWS SDK.

``js
const DynamoDB = require('@dazn/lambda-powertools-dynamodb-client')

await DynamoDB.put({
TableName: 'table-name',
Item: {
Id: 'theburningmonk'
}
}).promise()

await DynamoDB.update({
TableName: 'table-name',
Key: { Id: 'theburningmonk' },
UpdateExpression: 'SET #url = :url',
ExpressionAttributeNames: {
'#url': 'url'
},
ExpressionAttributeValues: {
':url': 'https://theburningmonk.com'
}
}).promise()

await DynamoDB.batchWrite({
RequestItems: {
['table-name']: [
{
DeleteRequest: {
Key: { Id: 'theburningmonk' }
}
},
{
PutRequest: {
Item: {
Id: 'theburningmonk'
}
}
}
]
}
}).promise()

await DynamoDB.transactWrite({
TransactItems: [
{
Put: {
TableName: 'table-name',
Item: {
Id: 'theburningmonk'
}
}
},
{
Update: {
TableName: tableName,
Key: { Id: 'theburningmonk' },
UpdateExpression: 'SET #url = :url',
ExpressionAttributeNames: {
'#url': 'url'
},
ExpressionAttributeValues: {
':url': 'https://theburningmonk.com'
}
}
}
]
}).promise()
