AWS Lambda is a serverless computing service that allows you to run the code without provisioning or managing the servers. It can automatically scale the application by the running code in response to triggers such as changes in data, shifts in system state, or user actions. In this article, we will guide you through the process of setting up the AWS Lambda in Visual Studio code and it can enable to develop and deploy Lambda functions efficiently.

Primary Terminologies

• AWS Lambda: The compute service that lets you run the code without provisioning or managing servers. We can pay only for the compute time you consume resources.
• Serverless: The cloud computing execution model where the cloud provider dynamically manages the allocation and provisioning of the servers.
• VS Code: A free source code editor made by Microsoft for Windows, macOS, and Linux with built-in support for JavaScript, TypeScript, and NodeJS.
• AWS Toolkit: The plugin for the IDEs like Visual Studio Code which provides the support for the Amazon Web Services. Making it easier to develop, debug, and deploy the applications on the AWS.

Step-by-step implementation of how to install AWS Lambda in Visual Studio Code

Step 1: Open the Visual Studio Code on your system.

Step 2: Now, we can go to the extensions view by clicking the extensions icon in the Activity Bar on the right side of the window or pressing the ctrl+shift+x.

Step 3: In Extensions view, search for the AWS Toolkit and select it from the results and click on install button and install the AWS Toolkit extension of the application.

Step 4: Install the Amazon Q Extension, click on install button and install the Amazon Q extension of the application.

Step 5: Now, We can open the Command Palette (Ctrl+shift+p) of the visual studio code.

Type: ” AWS Create Lambda SAM Application ” and select it.

Step 6: Choose the runtime for the Lambda function of the AWS Lambda in visual studio code.

Runtime: Java 11

Step 7: Choose the dependency manager for the Lambda function of the AWS Lambda in visual studio code.

Tool: Maven

Step 8: Choose the architecture for the Lambda function of the AWS Lambda in visual studio code.

Architecture : x86_64

Step 9: Choose the folder to save the Lambda function of the AWS Lambda in visual studio code.

Folder path: c:/docements/code

Refer the image for folder selection to save the project.

Step 10: Choose the project name of the Lambda function of the AWS Lambda in visual studio code.

Project Name: ExampleFunction

Step 11: Once complete the AWS Lambda function in visual code then it looks like the below image.

By the following these steps, we can set up and deploy the AWS Lambda functions directly from the Visual Studio Code, streaming the serverless development workflow of the application.
