-------------------------------------------------------------------------------- /backend/README.md: -------------------------------------------------------------------------------- 1 | # backend 2 | 3 | This project contains source code and supporting files for a serverless application that you can deploy with the SAM CLI. It includes the following files and folders: 4 | 5 | - functions - Code for the application's Lambda functions to check the value of, buy, or sell shares of a stock. 6 | - statemachines - Definition for the state machine that orchestrates the stock trading workflow. 7 | - template.yaml - A template that defines the application's AWS resources. 8 | 9 | This application creates a mock stock trading workflow which runs on a pre-defined schedule (note that the schedule is disabled by default to avoid incurring charges). It demonstrates the power of Step Functions to orchestrate Lambda functions and other AWS resources to form complex and robust workflows, coupled with event-driven development using Amazon EventBridge. 10 | 11 | AWS Step Functions lets you coordinate multiple AWS services into serverless workflows so you can build and update apps quickly. Using Step Functions, you can design and run workflows that stitch together services, such as AWS Lambda, AWS Fargate, and Amazon SageMaker, into feature-rich applications. 12 | 13 | The application uses several AWS resources, including Step Functions state machines, Lambda functions and an EventBridge rule trigger. These resources are defined in the `template.yaml` file in this project. You can update the template to add AWS resources through the same deployment process that updates your application code. 14 | 15 | If you prefer to use an integrated development environment (IDE) to build and test the Lambda functions within your application, you can use the AWS Toolkit. The AWS Toolkit is an open source plug-in for popular IDEs that uses the SAM CLI to build and deploy serverless applications on AWS. The AWS Toolkit also adds a simplified step-through debugging experience for Lambda function code. See the following links to get started: 16 | 17 | * [CLion](https://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/welcome.html) 18 | * [GoLand](https://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/welcome.html) 19 | * [IntelliJ](https://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/welcome.html) 20 | * [WebStorm](https://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/welcome.html) 21 | * [Rider](https://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/welcome.html) 22 | * [PhpStorm](https://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/welcome.html) 23 | * [PyCharm](https://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/welcome.html) 24 | * [RubyMine](https://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/welcome.html) 25 | * [DataGrip](https://docs.aws.amazon.com/toolkit-for-jetbrains/latest/userguide/welcome.html) 26 | * [VS Code](https://docs.aws.amazon.com/toolkit-for-vscode/latest/userguide/welcome.html) 27 | * [Visual Studio](https://docs.aws.amazon.com/toolkit-for-visual-studio/latest/user-guide/welcome.html) 28 | 29 | The AWS Toolkit for VS Code includes full support for state machine visualization, enabling you to visualize your state machine in real time as you build. The AWS Toolkit for VS Code includes a language server for Amazon States Language, which lints your state machine definition to highlight common errors, provides auto-complete support, and code snippets for each state, enabling you to build state machines faster. 30 | 31 | ## Deploy the sample application 32 | 33 | The Serverless Application Model Command Line Interface (SAM CLI) is an extension of the AWS CLI that adds functionality for building and testing Lambda applications. It uses Docker to run your functions in an Amazon Linux environment that matches Lambda. 34 | 35 | To use the SAM CLI, you need the following tools: 36 | 37 | * SAM CLI - [Install the SAM CLI](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install.html) 38 | * Node.js - [Install Node.js 14](https://nodejs.org/en/), including the NPM package management tool. 39 | * Docker - [Install Docker community edition](https://hub.docker.com/search/?type=edition&offering=community) 40 | 41 | To build and deploy your application for the first time, run the following in your shell: 42 | 43 | ```bash 44 | sam build 45 | sam deploy --guided 46 | ``` 47 | 48 | The first command will build the source of your application. The second command will package and deploy your application to AWS, with a series of prompts: 49 | 50 | * **Stack Name**: The name of the stack to deploy to CloudFormation. This should be unique to your account and region, and a good starting point would be something matching your project name. 51 | * **AWS Region**: The AWS region you want to deploy your app to. 52 | * **Confirm changes before deploy**: If set to yes, any change sets will be shown to you before execution for manual review. If set to no, the AWS SAM CLI will automatically deploy application changes. 53 | * **Allow SAM CLI IAM role creation**: Many AWS SAM templates, including this example, create AWS IAM roles required for the AWS Lambda function(s) included to access AWS services. By default, these are scoped down to minimum required permissions. To deploy an AWS CloudFormation stack which creates or modifies IAM roles, the `CAPABILITY_IAM` value for `capabilities` must be provided. If permission isn't provided through this prompt, to deploy this example you must explicitly pass `--capabilities CAPABILITY_IAM` to the `sam deploy` command. 54 | * **Save arguments to samconfig.toml**: If set to yes, your choices will be saved to a configuration file inside the project, so that in the future you can just re-run `sam deploy` without parameters to deploy changes to your application. 55 | 56 | You can find your State Machine ARN in the output values displayed after deployment. 57 | 58 | ## Use the SAM CLI to build and test locally 59 | 60 | Build the Lambda functions in your application with the `sam build --use-container` command. 61 | 62 | ```bash 63 | backend$ sam build 64 | ``` 65 | 66 | The SAM CLI installs dependencies defined in `functions/*/package.json`, creates a deployment package, and saves it in the `.aws-sam/build` folder. 67 | 68 | ## Add a resource to your application 69 | The application template uses AWS Serverless Application Model (AWS SAM) to define application resources. AWS SAM is an extension of AWS CloudFormation with a simpler syntax for configuring common serverless application resources such as functions, triggers, and APIs. For resources not included in [the SAM specification](https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md), you can use standard [AWS CloudFormation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-template-resource-type-ref.html) resource types. 70 | 71 | ## Fetch, tail, and filter Lambda function logs 72 | 73 | To simplify troubleshooting, SAM CLI has a command called `sam logs`. `sam logs` lets you fetch logs generated by your deployed Lambda function from the command line. In addition to printing the logs on the terminal, this command has several nifty features to help you quickly find the bug. 74 | 75 | `NOTE`: This command works for all AWS Lambda functions; not just the ones you deploy using SAM. 76 | 77 | ```bash 78 | backend$ sam logs -n StockCheckerFunction --stack-name backend --tail 79 | ``` 80 | 81 | You can find more information and examples about filtering Lambda function logs in the [SAM CLI Documentation](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-logging.html). 82 | 83 | ## Unit tests 84 | 85 | Tests are defined in the `functions/*/tests` folder in this project. Use NPM to install the [Mocha test framework](https://mochajs.org/) and run unit tests. 86 | 87 | ```bash 88 | backend$ cd functions/stock-checker 89 | stock-checker$ npm install 90 | stock-checker$ npm run test 91 | ``` 92 | 93 | ## Cleanup 94 | 95 | To delete the sample application that you created, use the AWS CLI. Assuming you used your project name for the stack name, you can run the following: 96 | 97 | ```bash 98 | aws cloudformation delete-stack --stack-name backend 99 | ``` 100 | 101 | ## Resources 102 | 103 | See the [AWS SAM developer guide](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/what-is-sam.html) for an introduction to SAM specification, the SAM CLI, and serverless application concepts. 104 | 105 | Next, you can use AWS Serverless Application Repository to deploy ready to use Apps that go beyond hello world samples and learn how authors developed their applications: [AWS Serverless Application Repository main page](https://aws.amazon.com/serverless/serverlessrepo/) 106 | -------------------------------------------------------------------------------- /backend/template.yaml: -------------------------------------------------------------------------------- 1 | AWSTemplateFormatVersion: "2010-09-09" 2 | Transform: AWS::Serverless-2016-10-31 3 | Description: > 4 | webhook management backend 5 | 6 | SAM Template for webhook management system 7 | 8 | Parameters: 9 | Stage: 10 | Type: String 11 | Default: 'dev' 12 | eventSource: 13 | Type: String 14 | Default: XYZCo 15 | EventBusName: 16 | Type: String 17 | Default: EventBusXYZCompany 18 | 19 | Resources: 20 | EventBus: 21 | Type: AWS::Events::EventBus 22 | Properties: 23 | Name: !Ref EventBusName 24 | 25 | SQSQueue: 26 | Type: AWS::SQS::Queue 27 | Properties: 28 | VisibilityTimeout: 60 29 | 30 | ApiGatewayApi: 31 | Type: AWS::Serverless::Api 32 | Properties: 33 | StageName: !Ref Stage 34 | Cors: 35 | AllowMethods: "'OPTIONS,POST,GET'" 36 | AllowHeaders: "'Content-Type'" 37 | AllowOrigin: "'*'" 38 | 39 | DynamodbTable: 40 | Type: AWS::DynamoDB::Table 41 | Properties: 42 | AttributeDefinitions: 43 | -
