prepare resource and app

Example Data for project: https://izara.io/wiki/index.php/Service_-_Product_Manager

• install package

example: in app

npm i @izara_project/izara-middleware
npm i @izara_project/izara-shared

//* install more see in package.json

Example:

• DynamoDb
• API Hdr
• SQS DSQ Hdr

set initial setup

in app/initial_setup

• initial_setup

start deploy to AWS server

• in config

1. iz_serviceName for beginner test => Service{YourName} ex: ServicePraew => if your project => ProductManager
2. iz_region for beginner test will use region => ap-southeast-2 //sydney => if your project will use region => us-east-2

• Config credentials aws, can run on home directory

1. check version

sls --version

aws --version

• Install the AWS CLI version 2 (window)

msiexec.exe /i https://awscli.amazonaws.com/AWSCLIV2.msi

ref: https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2-windows.html

• find Access Key and Secret Access Key

create Access key 1 from AWS server => User => your User Name

• configuration

aws configure

show:

AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE  // ***YOUR ID
AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY //***YOUR KEY
Default region name [None]: us-east-2 // Ohio
Default output format [None]: json

• deploy repository

deploy resource before app

sls deploy --verbose

Test

Example request for test Api|Sqs|Dqs handler

• Test

Task

• add Get|Delete|Update Product_Main Lambda for Api Handler
• create lambda that send msg to each lambda in same service

1. lambda => sns => sqs => lambda => maybe use handler Sqs
2. lambda => sqs => lambda => maybe use handler Dsq

• apply for use Inv Handler

1. lambda_1 will invoke lambda_2 to get data that return to lambda_1
   1. ex: lambda_1 => inv => lambda_2 => lambda_2 will return data => lambda_1

code example for use inv lambda:

let payload = {
  param: param
}

let lambda_2Record = await lambda.invokeSync(
  _izContext,
  lambdaSharedLib.lambdaFunctionName("Lambda_2_HdrInv"), //externalServiceName if inv|send msg external service need to put service that get data
  payload
);
