AWS Lambda プロキシ統合 + Node.js 8.10 index.handler

Lambda プロキシ統合での 関数コード例:

exports.handler = async(event) => {
    const addr = require('./addr.json');
    const keywords = event.queryStringParameters.q.replace(/-/, "").trim().split(/\s+/);
 ...
 const response = {
  statusCode: 200,
  body: JSON.stringify(patterns),
 };
 return response;
};

メモ
- response.body は文字列で返します。
