Installing and Using Cargo Lambda
Cargo Lambda: Streamlining AWS Lambda Development
Overview of Installing and Using
Cargo Lambda, a powerful tool for interacting with the AWS Lambda ecosystem. It simplifies the process of running, building, and deploying Lambda functions natively, without the need for containers or VMs. The discussion covers installation methods, getting started with Cargo Lambda, and its advantages over traditional scripting languages for Lambda development.
-
Introduction to Cargo Lambda
- Interacts with AWS Lambda ecosystem from the terminal
- Enables native running, building, and deployment of Lambda functions
- No need for containers or VMs
-
Installation Options
- Homebrew (recommended for macOS and Linux)
- Scoop for Windows
- Docker and Nix as alternatives
- Binary release or building from source
-
Getting Started
- Use
cargo lambda new
to create a project - Directory structure includes package management, default code, compiler, and linter
cargo lambda watch
for immediate code writingcargo lambda invoke
for testing with JSON payloads
- Use
