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." }});
}
