実行手順

時間の都合により、環境を用意できなかったため、dockerの入った環境で、 digi-con-hackathon2025から ./scripts/start-dev.sh を実行してください。 その後、 http://localhost:3000 にブラウザからアクセスを行ってください。

Start everything with one command

./scripts/start-dev.sh

Test it works

API - curl http://localhost:8080/health Localstack Bucket - docker-compose exec localstack awslocal s3 ls

• API: http://localhost:8080
• Database Admin: http://localhost:8081 (Adminer)

    System: PostgreSQL
    Server: postgres
    Username: postgres
    Password: password
    Database: hackathon_db

• PostgreSQL: localhost:5432
• Redis: localhost:6379 (for future caching needs)

API: [POST] http://localhost:8080/api/v1/auth/login - authenticate and get token Request Body: { "email": "test@example.com", "password": "password123" } [GET] http://localhost:8080/api/v1/profile - get current profile

File Uploads

Organizer-hosted Presign (App Runner):

# Get presigned PUT URL
curl -s -X POST "https://bpijpynumu.ap-northeast-1.awsapprunner.com/presign-upload" \
  -H "X-Team-Id: <your-team-id>" \
  -H "X-Team-Token: <your-team-token>" \
  -H 'Content-Type: application/json' \
  -d '{"filename":"hello.txt","content_type":"text/plain"}'

# Upload your file with the returned URL
printf 'Hello, Hackathon!\n' > hello.txt
curl -X PUT --upload-file ./hello.txt -H 'Content-Type: text/plain' "<url-from-step-1>"

# Presign GET to download
curl -s -X POST "https://bpijpynumu.ap-northeast-1.awsapprunner.com/presign-get" \
  -H "X-Team-Id: <your-team-id>" \
  -H "X-Team-Token: <your-team-token>" \
  -H 'Content-Type: application/json' \
  -d '{"key":"uploads/<your-team-id>/<object-key>"}'

Local API + LocalStack (optional for local dev):

# Get presigned PUT URL (JWT required)
TOKEN=<your-jwt>
RES=$(curl -s -X POST http://localhost:8080/api/v1/storage/presign \
  -H "Authorization: Bearer $TOKEN" \
  -H 'Content-Type: application/json' \
  -d '{"filename":"hello.txt","content_type":"text/plain"}')
URL=$(echo "$RES" | jq -r .url)

# Host override: the API now supports AWS_PUBLIC_ENDPOINT_URL. By default, it uses http://localhost:4566 for presigned URLs so you can upload from your host without edits.
printf 'Hello, Hackathon!\n' > hello.txt
curl -X PUT --upload-file ./hello.txt -H 'Content-Type: text/plain' "$URL"

# One-step multipart upload (server-side)
curl -X POST http://localhost:8080/api/v1/upload \
  -H "Authorization: Bearer $TOKEN" \
  -F "file=@hello.txt"

LocalStack note (ap-northeast-1):

docker-compose exec localstack awslocal s3api create-bucket \
  --bucket hackathon-uploads \
  --create-bucket-configuration LocationConstraint=ap-northeast-1
