import uuid from "uuid";
import * as dynamoDbLib from "./libs/dynamodb-lib";

export async function main(event, context) {
  const data = JSON.parse(event.body);
  const params = {
    TableName: process.env.tableName,
    Item: {
      userId: event.requestContext.identity.cognitoIdentityId,
      noteId: uuid.v1(),
      content: data.content,
      attachment: data.attachment,
      createdAt: Date.now()
    }
  };

  try {
    await dynamoDbLib.call("put", params);
    return response.success({ data: params.Item});
  } catch (e) {
    return response.failure({ error: { message: "Something went wrong." }});
  }
