Prerequisites

Before you begin, make sure you have the following installed and set up:

• Go
• Serverless CLI

Getting Started

Clone this repository to your local machine:

git clone https://github.com/swarajkumarsingh/aws-lambda-go.git
cd aws-lambda-go

Building the Go Server

Build your Go server binary:

make build

make build-windows (for windows optional)

Configuration

serverless.yml - file contains all configs related to deployment options

service: serverless-rest-api-3
frameworkVersion: '>=1.28.0'
provider:
  name: aws
  runtime: go1.x
  stage: ${opt:stage, 'dev'}
  region: ap-south-1

          cors: true
      
package:
  patterns:
    - '!*/**'
    - bin/main

Deploying to AWS Lambda

Use serverless cli for deploying

make deploy(this will build the project and deploy it)

Testing

After you deploy, you will be given a url

curl <give-url>

Clean-Up

- Head to your AWS console
- Search 'CloudFormation'
- Select your stack via name
- Delete it
- Verify this, by going to lambda make sure there is no running lambda function via your project name
