What's the best way to invoke another function? (or get it's ARN)

reccomend using @events or @queues for 'background tasks' (events are SNS topics, unordered ans async…queues are SQS fifo queues)

is it safe to put await arc.tables() outside the event handler of a function?

you can, it will make a one time call to SSM to resolve generated table names with the names defined .arc but generally I'd reccomend keeping things deterministic as possible and doing it in the main function body

how does specifying a ddb trigger look?

brianleroux

// get the client
let data = await arc.tables()

// get the generated table names
let tables = await data.reflect()

// use the document client directly 
data._doc.batchGet({TableName: tables.mytable ...})

let aws = require('aws-sdk')
let region = 'us-west-1'
let db = new aws.DynamoDB.DocumentClient({region})

db.query({
  TableName: 'begin-production-builds',
  IndexName: 'begin-production-builds-appID_env-ts-index',
  KeyConditionExpression: '#appID_env = :appID_env',
  ExpressionAttributeNames: {
    '#appID_env': 'appID_env'

create a $default route lambda

run sam deploy --template-file sam.yaml --stack-name Hi --capabilities CAPABILITY_IAM to see the default route…the invoke persmission will be invalid but even brute forcing it fails

let aws = require('aws-sdk')
let cfn = new aws.CloudFormation

let StackName = 'your stackname here'
let isLambda = i=> i.ResourceType === 'AWS::Lambda::Function'
let resources = await cfn.listStackResources({StackName}).promise()
let functions = data.StackResourceSummaries.filter(isLambda)

add arc locally

```bash
npm init -f
npm i @architect/architect
```

edit `package.json` with a startup script
