BREAKING CHANGES since version 2.0

Now dynamo tools returns an object and not directly an array of items.

{
    Items:[ { ....} , { ... } ],
    LastEvaluatedKey: {....}
}

Installation

$ npm install @voodoo.io/aws-utils --save

Usage

Dynamo tools

Configure dynamo tools

const awsUtils = require('@voodoo.io/aws-utils').dynamo;

const aws = require('aws-sdk');
aws.config.update({region: 'eu-west-1'});
const dynamoCli = new aws.DynamoDB.DocumentClient();
const dynamoTools = new awsUtils(dynamoCli)

Query

const res = await dynamoTools.queryHashKey('myTable', 'key', 'value');

const res = await dynamoTools.query('myTable', { 'conditions': [{'key': 'value', 'operator': 'value', 'value': [] /** or ''**/}]})

Scan

const res = await dynamoTools.scan('myTable');

Put item

const res = await dynamoTools.putItem('myTable', {'key': 'value'});

Put items

const res = await dynamoTools.putItems('myTable', [{'key': 'value'}]);

Put transactional items

const res = await dynamoTools.putTransactionItems([{'key': 'value'}]);

Update item

await dynamoTools.update('myTable', {'key': {'primaryKey': 'value', 'sortKey': 'value'},'add': {['column1']: 'value'}, 'set': {'column2': 'value'}});

delete item

const res = await dynamoTools.deleteItem('myTable', {'key': 'value'});

queryHashKey(dynamoTable, hashKeyName, hashKeyValue, [exclusiveStartKey], [limit])

• dynamoTable : table's name
• hashKeyName : hashkey's name
• hashKeyValue : hashkey's value
• exclusiveStartKey : (optional) start search at a specific key
• limit : (optional) don't return more items than the limit

query(dynamoTable, customParams)

• dynamoTable : table's name
• customParams : object with the conditions of the query

putItem(dynamoTable, item)

• dynamoTable : table's name
• item : item to insert

putItems(dynamoTable, items)

• dynamoTable : table's name
• item : an array of items to insert

scan(dynamoTable, [hashKeyName], [hashKeyValue], [exclusiveStartKey], [limit])

• dynamoTable : table's name
• hashKeyName : (optional) hashkey's name
• hashKeyValue : (optional) hashkey's value
• exclusiveStartKey : (optional) start search at a specific key
• limit : (optional) don't return more items than the limit

If no hashkey is provided it returns the full table.

updateItem(dynamoTable, params)

• dynamoTable : table's name
• params : parameters with columns to update

deleteItem(dynamoTable, key)

• dynamoTable : table's name
• key : hashkey to delete

Secret Manager tools

Configure secret manager tools

const awsUtils = require('@voodoo.io/aws-utils').secretManager;

const aws = require('aws-sdk');
aws.config.update({region: 'eu-west-1'});
const cli = new aws.SecretsManager({});
const secretManagerTools = new awsUtils(cli);

getSecretValue

const res = await secretManagerTools.getSecretValue('secret');

getSecretValue(secret)

• secret : secret's id

S3 tools

Configure S3 tools

const awsUtils = require('@voodoo.io/aws-utils').s3;

const aws = require('aws-sdk');
aws.config.update({region: 'eu-west-1'});
const cli = new aws.S3();
const s3Tools = new awsUtils(cli);

getObject

const res = await s3Tools.getObject('bucket', 'key');

getObject(bucket, key)

• bucket : bucket's name
• key : path to the ressource (/path/file.json)

putJsonObject

const res = await s3Tools.putJsonObject('bucket', 'key', {"key": "value"});

putJsonObject(bucket, key, item)

• bucket : bucket's name
• key : path to the ressource (/path/file.json)
• item : json object to save on S3

emptyS3Directory

const res = await s3Tools.emptyS3Directory('bucket', 'dir/');

emptyS3Directory(bucket, dir)

• bucket : bucket's name
• dir : directory to remove
