rust-actix-web-zip

This project contains source code and supporting files for a serverless Actix Web application that you can deploy with the SAM CLI. It includes the following files and folders:

• Cargo.toml - Project configuration file.
• src - Code for the Actix Web application.
• template.yaml - A template that defines the application's AWS resources.

The application uses several AWS resources, including Lambda functions and an API Gateway API. 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.

If you prefer to use an integrated development environment (IDE) to build and test 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.

• CLion
• GoLand
• IntelliJ
• WebStorm
• Rider
• PhpStorm
• PyCharm
• RubyMine
• DataGrip
• VS Code
• Visual Studio

Requirments

• This template was tested with Rust v1.66.0 and above.

Deploy the sample application

To deploy the application, you need the folllowing tools:

• SAM CLI - Install the SAM CLI
• Docker - Install Docker community edition
• Rust version 1.56.0 or newer
• cargo-lambda for cross-compilation

To build and deploy your application for the first time, run the following in your shell:

sam build
sam deploy --guided

The first command will build the source of your application. The second command will package and deploy your application to AWS.

You can find your API Gateway Endpoint URL in the output values displayed after deployment.

Add a resource to your application

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, you can use standard AWS CloudFormation resource types.

Fetch, tail, and filter Lambda function logs

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.

NOTE: This command works for all AWS Lambda functions; not just the ones you deploy using SAM.

rust-actix-web-zip$ sam logs --stack-name rust-actix-web-zip --tail

You can find more information and examples about filtering Lambda function logs in the SAM CLI Documentation.

Tests

You can run and test the Actix Web application locally.

cd rust_app
cargo run

Cleanup

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:

sam delete
