海外TECH	DEV Community	Learn serverless on AWS step-by-step - Step Functions	https://dev.to/kumo/learn-serverless-on-aws-step-by-step-step-functions-4m7c	Learn serverless on AWS step by step Step Functions TL DRIn this series I try to explain the basics of serverless on AWS to enable you to build your own serverless applications With last article we discovered how to create a REST API protected by authentication using Cognito In this article let s dive into Step Functions a service that allows you to orchestrate your serverless applications by building state machines interacting with other AWS services IntroductionWhen building a serverless application you want to minimize the responsibilities of each component especially Lambda functions You want them to do one thing and do it well To avoid building monolithic functions that have tons of side effects and are hard to debug a simple way to do it is to use AWS Step Functions Instead of having a single Lambda handling data retrieval processing storage and side effects like messaging you can split these responsibilities into multiple Lambdas and use Step Functions to orchestrate them You can even get rid of Lambda functions and directly integrate with other AWS services like DynamoDB S SQS SNS etc it s called Functionless programming Today we are going to build together a simple shopping application We will create a database composed of products each product will have a stock We will then create a state machine allowing to create an order based on a shopping cart First it will check that every product is in stock then it will create the order and update the stock of each product at the same time This orchestration will be done using Step Functions and will allow to avoid creating an order if one the products is not in stock We can describe the architecture of our application like this The DB will store products and orders and a create store item will allow to create a new product The state machine will be triggered by an API Gateway with the create order route First thanks to a Map state it will check that every product is in stock Then in case of success it will in parallel create an orderupdate the stock of each product thanks to another Map state A map state allows the state machine to iterate over an array of items and execute a task for each item If one of the tasks fails the whole state machine fails If all the tasks succeed the state machine will continue to the next state Creating a database an API and all necessary Lambda functionsLet s start by creating the building blocks of our application We will create a DynamoDB table to store products and orders an API Gateway to trigger our state machine and all the Lambda functions that will be used by our state machine To provision these resources I will use the AWS CDK combined with TypeScript If you are not familiar with this method feel free to check out the previous articles of this series where I explain how to use it Nothing will be new in this section I already covered Lambda functions DynamoDB tables and API Gateways in previous articles Provisioning resourcesStart by creating a new CDK stack import as cdk from aws cdk lib import Construct from constructs import path from path export class LearnServerlessStack extends cdk Stack constructor scope Construct id string props cdk StackProps super scope id props Provision a new REST API Gateway const myFirstApi new cdk aws apigateway RestApi this myFirstApi Provision a new DynamoDB table const storeDB new cdk aws dynamodb Table this storeDB partitionKey name PK type cdk aws dynamodb AttributeType STRING sortKey name SK type cdk aws dynamodb AttributeType STRING billingMode cdk aws dynamodb BillingMode PAY PER REQUEST Provision a new Lambda function and grant it read access to the DynamoDB table const isItemInStock new cdk aws lambda nodejs NodejsFunction this isItemInStock entry path join dirname isItemInStock handler ts handler handler environment TABLE NAME storeDB tableName storeDB grantReadData isItemInStock Provision a new Lambda function and grant it write access to the DynamoDB table const updateItemStock new cdk aws lambda nodejs NodejsFunction this updateItemStock entry path join dirname updateItemStock handler ts handler handler environment TABLE NAME storeDB tableName storeDB grantWriteData updateItemStock Provision a new Lambda function and grant it write access to the DynamoDB table const createOrder new cdk aws lambda nodejs NodejsFunction this createOrder entry path join dirname createOrder handler ts handler handler environment TABLE NAME storeDB tableName storeDB grantWriteData createOrder Provision a new Lambda function and grant it write access to the DynamoDB table const createStoreItem new cdk aws lambda nodejs NodejsFunction this createStoreItem entry path join dirname createStoreItem handler ts handler handler environment TABLE NAME storeDB tableName storeDB grantWriteData createStoreItem Add a new POST route to the REST API Gateway and link it to the createStoreItem Lambda function const createStoreItemResource myFirstApi root addResource create store item createStoreItemResource addMethod POST new cdk aws apigateway LambdaIntegration createStoreItem Nothing new here I create the necessary resources pass the table name as an environment variable to the Lambda functions and grant them the necessary permissions Adding code to Lambda functionsResources are now provisioned the only part missing is the code of the Lambda functions Let s start by the createStoreItem function import DynamoDBClient PutItemCommand from aws sdk client dynamodb const client new DynamoDBClient export const handler async body body string Promise lt statusCode number body string gt gt const tableName process env TABLE NAME const itemId quantity JSON parse body as itemId string quantity number if itemId undefined quantity undefined return statusCode body JSON stringify message itemId or quantity is undefined await client send new PutItemCommand TableName tableName Item PK S StoreItem SK S itemId stock N quantity toString return statusCode body JSON stringify message Store item created This lambda function will be plugged into an API so it has to respect a certain typing I quickly sanity check the input and then use the DynamoDB SDK to create a new item in the table Here I choose the data structure of the StoreItems in the DB the PK will be a constant string StoreItem and the SK will be the itemId I also add a stock attribute which will be a number If you do not feel comfortable with DynamoDB feel free to check out my dynamoDB article where I explain how to use it Then let s create the isItemInStock function import DynamoDBClient GetItemCommand from aws sdk client dynamodb const client new DynamoDBClient export const handler async item itemId quantity item itemId string quantity number Promise lt void gt gt const tableName process env TABLE NAME const Item await client send new GetItemCommand TableName tableName Key PK S StoreItem SK S itemId const stock Item stock N if stock undefined stock lt quantity throw new Error Item not in stock Because it is a building block of the future state machine the typing is simpler This function receives a single item composed of an itemId and a quantity It will check in the store DB if the item is in stock and throw an error if it is not Then let s create the updateItemStock function import DynamoDBClient UpdateItemCommand from aws sdk client dynamodb const client new DynamoDBClient export const handler async item itemId quantity item itemId string quantity number Promise lt void gt gt const tableName process env TABLE NAME await client send new UpdateItemCommand TableName tableName Key PK S StoreItem SK S itemId UpdateExpression SET stock stock quantity ExpressionAttributeValues quantity N quantity toString In this lambda the input is the same To update the stock of an item without knowing its current value I use an UpdateExpression with the SET keyword I also use an ExpressionAttributeValues to pass the quantity value to the expression Finally let s create the createOrder function import DynamoDBClient PutItemCommand from aws sdk client dynamodb import v as uuid from uuid const client new DynamoDBClient export const handler async order order itemId string quantity number Promise lt void gt gt const tableName process env TABLE NAME await client send new PutItemCommand TableName tableName Item PK S Order SK S uuid order L order map itemId quantity gt M itemId S itemId quantity N quantity toString Here I put a new item in the DB with a random SK and a constant PK The order attribute is an array L for List of items M for Map each item being composed of an itemId and a quantity We are done with the code Notice none of the Lambda functions I created have more than one responsibility They are all very simple and easy to debug Furthermore they do not return any value the state machine will handle the data flow between them Creating a state machine to orchestrate the applicationThe exciting part of this article is coming We are going to provision a new state machine that will handle the flow of data between the Lambda functions isItemInStock updateItemStock and createOrder First let s settle for a data structure the input of the state machine will be of the following type order itemId string quantity number Notice how it interacts with the input types I defined for the Lambda functions isItemInStock and updateItemStock expect a single item of the inputcreateOrder expects the full array of items Let s start by creating tasks Tasks are the building blocks of state machines I will create tasks one for each Lambda function import JsonPath from aws cdk lib aws stepfunctions Create a Map task iterating over the items of the inputconst isItemInStockMappedTask new cdk aws stepfunctions Map this isItemInStockMappedTask itemsPath order resultPath JsonPath DISCARD parameters item Map Item Value iterator new cdk aws stepfunctions tasks LambdaInvoke this isItemInStockTask lambdaFunction isItemInStock Create a Map task iterating over the items of the inputconst updateItemStockMappedTask new cdk aws stepfunctions Map this updateItemStockMappedTask itemsPath order resultPath JsonPath DISCARD parameters item Map Item Value iterator new cdk aws stepfunctions tasks LambdaInvoke this updateItemStockTask lambdaFunction updateItemStock Create simple task calling the createOrder Lambda functionconst createOrderTask new cdk aws stepfunctions tasks LambdaInvoke this createOrderTask lambdaFunction createOrder There is a lot to be discussed in the above code snippet Map tasks are used to iterate over an array of items and execute a task for each item itemsPath is used to specify where to find the array of items in the input Based on the input the array of items is located at order It is a special AWS syntax you can learn more about it here parameters is used to specify the input of the task Here I want to pass the item I have iterated over to the Lambda function I use the special syntax to access the current item of the iteration Once again more details can be found in the AWS documentation resultPath is used to specify where to store the result of the task Here I do not want to store the result of the task so I discard it LambdaInvoke tasks are used to call a Lambda function We simply specify the Lambda function to call based on what we provisioned earlier The three building blocks of the state machine are ready let s orchestrate them by creating a new state machine const parallelState new cdk aws stepfunctions Parallel this parallelState parallelState branch updateItemStockMappedTask createOrderTask const definition isItemInStockMappedTask next parallelState const myFirstStateMachine new cdk aws stepfunctions StateMachine this myFirstStateMachine definition Looking at the definition we see that we first execute the isItemInStockMappedTask then the parallelState The parallelState is composed of two branches updateItemStockMappedTaskcreateOrderTaskThe cool thing is that the parallel state will only execute if the isItemInStockMappedTask succeeds if every task of the map succeeds If it fails the state machine will stop Triggering the state machine with an API GatewayThe icing on the cake we are going to trigger the state machine with an API call To demonstrate functionless programming we will not use a Lambda function to trigger the state machine but directly the API Gateway To do this I have two things to do Create an IAM role allowing the API Gateway to trigger the state machineCreate a new POST route on the API Gateway and link it to the state machine The route will assume the IAM role to be able to trigger the state machine Creating an IAM role to execute the state machineThe creation of the IAM role is pretty straightforward const invokeStateMachineRole new cdk aws iam Role this invokeStateMachineRole assumedBy new cdk aws iam ServicePrincipal apigateway amazonaws com invokeStateMachineRole addToPolicy new cdk aws iam PolicyStatement actions states StartExecution resources myFirstStateMachine stateMachineArn First by setting a principal I define that the role will be assumed by an API Then I add a policy allowing the API to start the execution of the state machine and I specify the state machine ARN to narrow the scope of the policy only to this state machine Triggering the state machine with a POST routeThis part is a little bit more convoluted const createOrderResource myFirstApi root addResource create order createOrderResource addMethod POST new cdk aws apigateway Integration type cdk aws apigateway IntegrationType AWS integrationHttpMethod POST uri arn aws apigateway cdk Aws REGION states action StartExecution options credentialsRole invokeStateMachineRole requestTemplates application json input order util escapeJavaScript input json stateMachineArn myFirstStateMachine stateMachineArn integrationResponses statusCode responseTemplates application json statusCode body message OK methodResponses statusCode First I add a new POST route to the API Then instead of plugging it to a Lambda function like we are used to I define a custom integration This integration will allow me to call the state machine directly Worth to be noted The uri is a special AWS syntax that allows to call a specific AWS service Here I call the StartExecution action of the states service which is the Step Functions service In the options I specify the IAM role to assume the one I create earlier I specify the input of the state machine In the input field using the same AWS syntax as before I transform the body of the POST route into the data structure expected by the state machine In the stateMachineArn field I specify the ARN of the state machine to call I specify the response of the API Here I simply return a status code with a message Finally in the method responses I specify the response of the API Here I simply return a status code This response has to match with one of the responses defined in the integrationResponses or the API will return a status code This part was quite advanced here is a really nice article I found going more into details about this integration I highly recommend you to read it Do not hesitate to contact me if you have any questions I will be happy to help We are done with the code Time to deploy it npm run cdk deploy Testing the applicationFirst let s start by creating new products here is an example request Then let s create a new order Taking a look at the logs of the state machine we can see that it succeeded and we find the same structure as what was planned at the beginning of the article Finally let s check the content of the DB We can see that the order has been created and the stock of each product has been updated If we try to repeat the same request the state machine will eventually fail because the products are not in stock anymore ConclusionThis tutorial was a shallow introduction to Step Functions Much more can be done with this service especially using messaging services like SES or SNS to send notifications to users Stay tuned I will cover these topics in future articles I plan to continue this series of articles on a bi monthly basis I already covered the creation of simple lambda functions and REST APIs as well as interacting with DynamoDB databases and S buckets You can follow this progress on my repository I will cover new topics like creating event driven applications type safety and more If you have any suggestions do not hesitate to contact me I would really appreciate if you could react and share this article with your friends and colleagues It will help me a lot to grow my audience Also don t forget to subscribe to be updated when the next article comes out I you want to stay in touch here is my
