Udagram Image Filtering Microservice

Udagram is a simple cloud application developed alongside the Udacity Cloud Engineering Nanodegree. It allows users to register and log into a web client, post photos to the feed, and process photos using an image filtering microservice.

The project is split into three parts:

1. The Simple Frontend A basic Ionic client web application which consumes the RestAPI Backend. [Covered in the course]
2. The RestAPI Backend, a Node-Express server which can be deployed to a cloud service. [Covered in the course]
3. The Image Filtering Microservice, the final project for the course. It is a Node-Express application which runs a simple script to process images. [My assignment]

Tasks

Setup Node Environment

You'll need to create a new node server. Open a new terminal within the project directory and run:

1. Initialize a new project: npm i
2. run the development server with npm run dev

Create a new endpoint in the server.ts file

The starter code has a task for you to complete an endpoint in ./src/server.ts which uses query parameter to download an image from a public URL, filter the image, and return the result.

We've included a few helper functions to handle some of these concepts and we're importing it for you at the top of the ./src/server.ts file.

import {filterImageFromURL, deleteLocalFiles} from './util/util';

Deploying your system

Follow the process described in the course to eb init a new application and eb create a new environment to deploy your image-filter service! Don't forget you can use eb deploy to push changes.
