# Powerslog

A slog handler that captures key fields from an AWS Lambda context and produces

structured logs with the same fields as the Powertools loggers for Python and

TypeScript.

## Getting started

### Requirements

- [Go] 1.22+

### Installation and usage

```go

package main

import (

    "context"

    "log/slog"

    "net/http"

    "os"

    "github.com/aws/aws-lambda-go/events"

    "github.com/aws/aws-lambda-go/lambda"

    "github.com/unfunco/powerslog"

)

func handler(ctx context.Context, event events.APIGatewayProxyRequest) (events.APIGatewayProxyResponse, error) {

    logger := ctx.Value("logger").(*slog.Logger)

    logger.Info("Request received", slog.Any("event", event))

    return events.APIGatewayProxyResponse{

        StatusCode: http.StatusNoContent,

    }, nil

}

func main() {

    jsonHandler := slog.NewJSONHandler(os.Stdout, nil)

    powerslogHandler := powerslog.NewHandler(jsonHandler)

    logger := slog.New(powerslogHandler)

    ctx := context.WithValue(context.Background(), "logger", logger)

    lambda.StartWithOptions(handler, lambda.WithContext(ctx))

}

```

### Development and testing

```bash

cd lambda

GOOS=linux GOARCH=arm64 go build -tags lambda.norpc -o bootstrap main.go

sam deploy --guided

```
