Simple S3 DB

A simple key value pair API which stores values within S3.

Usage

npm install simple-s3-db

const SimpleS3DB = require( 'simple-s3-db' );
const AWS = require( 'aws-sdk' );

const db = new SimpleS3DB( new AWS.S3(), 'my-bucket-name' );

Put

db.put( 'object-key', {
    id: "1",
    name: "Some name"
} )
    .then( result => { 
        // Do something here, or don't, whatever ... 
    } );

Putting Objects in a Folder

To place an object in a folder simply delimit the folder with / in your object key.

db.put( 'object-folder/object-key', {
    id: "1",
    name: "Some name"
} )
    .then( result => { 
        // Do something here
    } );

Get

db.get( 'object-key' )
    .then( result => { 
        // Do something here 
    } );

Result Object

• data: object what was put in the first place

Delete

db.delete( 'object-key' )
    .then( result => {
        // Do something here
    } );

Deleting Multiple Objects

You can delete multiple objects at once by passing an array of keys. This is particularly useful in conjunction with the list operation below.

db.list( 'object-folder' ) 
    .then( result => {
        return db.delete( result.data );
    } )
    .then( result => {
        // Do something here
    } );

List

db.list( 'object-folder' )
    .then( result => { 
        // Do something here 
    } );

Result Object

• data: array<string> array of object keys contained in the folder

Getting All the Things in a Folder

The general pattern for getting all the objects in a folder is to list the folder and then map the list to the objects.

db.list( 'object-folder' )
    .then( result => {
        return Promise.all( 
                result.data.map( currentKey => db.get( currentKey ) ) 
            );
    } )
    .then( objects => {
        // Do Something here
    } );
