What I built

I built a file manager for people to share files freely on the internet

Features

Allows new users to signup so that they can share files
Allows users to upload files & generate a public shareable link
Allows the user to control whether an uploaded file is public or not
Allows users to preview the files before downloading them

Description

File manager is an online free-to-use platform where users can store & share their files with each other. The files can be either public or private as per the user's needs. The backend is built using Typescript & frontend uses Bootstrap & Edge templating.

Background

Recently, I've been looking for a solution to share my files online but all the sharers were either paid or slow or had some kind of time restriction. So, I decided to build this file manager so that more people like me can share files with each other online for free without any worry.

How I built it

I built this using the AdonisJS framework for the backend & bootstrap for the frontend along with Linode services. I used the following Linode services:

Object Storage: Linode's object storage is S3 compatible so I used it to store all the files that were uploaded by users. It was very easy to set up & use due to Linode's documentation. It was my first time using any sort of object storage and I got to learn how S3 & object storage in general work due to this
Managed Postgres DB: Linode provides a managed PostgreSQL database which means that I don't have to configure it much and still get the industry standard database. This was very useful to me as I'm still learning about managing databases and saved me a lot of trouble along the way.
Linode: I created a linode using this guide & installed node.js & nginx on it. This was my first time setting up a virtual machine from scratch and Linode's guides helped me out a lot on this journey.
Linode Firewalls: Originally, I did not know anything about having a firewall on the Linode machine but reading Linode's guides gave me an idea about them & helped me understand their usefulness. Using Linode's firewall I blocked all ports except for 22 & 80 on my machine which helped in securing it.

Overall, I gained many new skills & knowledge along the way due to Linode's free 100$ credits and this hackathon. My next step would be to figure out how to make better use of the free credits & keep on improving my skills.

Future Scope

Allow users more control over who can access their files
Store statistics regarding page views for public files
Make APIs for uploading files so that this can be turned into a SaaS
Better UI for users
Add CDN for retrieving files

Redis-OM Lambda CDK

Overview of My Submission

This sample shows how to define a Lambda function which uses Redis-om via AWS Cloud Development Kit. This is a fork of prisma-lambda-cdk sample repo which replaces mysql/postgres with redis stack & prisma with Redis-om.

By this sample, you can see how a Lambda function which uses Redis OM can be deployed with CDK, how indexes can be created from Lambda, and how Redis OM works in Lambda.

Build and deploy a Lambda function with Redis OM by AWS Cloud Development Kit.

Redis-OM Lambda CDK Sample Application

Redis OM is an open source object mapping, search etc library for Redis written in Typescript & very useful with its developer friendly API.

By this sample, you can see how a Lambda function which uses Redis OM can be deployed with CDK, how indexes can be created from Lambda, and how Redis OM works in Lambda.

How it works

Architecture

This sample consists of the following AWS services:

Amazon VPC
Redis Cloud (Amazon doesn't offer redis stack yet)
AWS Lambda

There're two Lambda functions:

a function that reads and writes records from/to Redis handler.ts
a function that sets up the index for Request entity migration-runner.ts

Performance Benchmarks

I did the testing for both lambda functions by creating a url for them and then using k6 to test them.
Terminology:

VU Count: Number of concurrent requests being made
Duration: The duration for which test was run
Function type: Type of Lambda function executed
Prisma p95: p95 response time of prisma lambda function
Redis OM p95: p95 response time of redis om lambda function
Prisma p90: p90 response time of prisma lambda function
Redis OM 90: p90 response time of redis om lambda function
Prisma AVG: Avg response time of prisma lambda function
Redis OM AVG: Avg response time of redis om lambda function

VU Count	Duration	Function Type	Prisma p95	Redis OM P95	Prisma p90	Redis OM p90	Prisma AVG	Redis OM AVG	Prisma Failed Reqs	Redis OM Failed Reqs
10	30s	Handler - Create Data	91.99 ms	67.56 ms	74.57 ms	60.4 ms	71.56 ms	57.16 ms	0	0
20	30s	Handler - Create Data	89.35ms	65.7ms	74ms	59.19ms	70.56ms	54.73ms	26.60%	24.66%
20	30s	Handler - Retrieve Data	698.56ms	516.26ms	600.07ms	394.06ms	547.38ms	344.9ms	0	0
20	30s	Migration Runner	10.87s	3.16s	8.95s	2.93s	7.8s	2.67s	0	0

From these stats we can infer that there's a signifact performance boost when migrating schemas using Redis OM instead of Prisma.
Reads from Redis are also faster than Mysql & while not much but writes are faster as well.
