Hello everybody! I am new to this so sorry for such silly question
I’m trying to update my .csv file in s3 bucket but got no clue how to handle it.
Seems like i found the right method but still have nothing in the end.
Let me show u how i do this.
const params ={
Bucket: 'myBucketName',
Key: 'something.csv',
Body: JSON.stringify(itemToUpload)
}
s3.putObject(params).promise();
I’m trying to specify my bucket in .yml file but it rejects with an error like “Bucket already exists”.
What should i do to solve my problem?
Post full code should be better
const AWS = require(‘aws-sdk’);
const documentClient = new AWS.DynamoDB.DocumentClient();
const s3 = new AWS.S3({ region: ‘eu-west-1’ });
const bucketName = process.env.bucketName;
const fiveMinsInMili = process.env.fiveMinsInMili;
exports.handler = async event => {
console.log('event', event);
console.log('save to s3 lambda');
const nowTimestamp = new Date().getTime();
const params = {
TableName: 'Weather',
Select: "ALL_ATTRIBUTES"
};
const items = await documentClient.scan(params).promise();
const { Items } = items;
s3.putObject(params).promise();
Items.map(i => {
if (nowTimestamp - i.timestamp <= fiveMinsInMili) {
const putParams = {
Bucket: bucketName,
Key: 'weather.csv',
Body: JSON.stringify(i)
}
s3.putObject(putParams, (err) => {
if (err) console.log(err);
else console.log('Its OK!');
})
}})
};
