Udacity Image Filter Project - FullStack Apps On AWS - Cloud Developer Nanodegree

Udagram Image Filtering Microservice

FullStack Apps On AWS

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.

This submission is for deploying a simple image filtering service using AWS ElasticBeanStalk service.

The starter code is available below: The Image Filtering Microservice

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.

USAGE

REQUEST JWT TOKEN

In order to do a request for image filtering, you need to be authenticated using a JWT token.

1. A token can be requested using a post request the api /token with a body (ex: {"name": "YOUR_NAME"})
2. Copy token field from the response
3. Use this key in your request example Bearer [TOKEN]. Replace [TOKEN] with the one you copied previously.
4. A request parameter image_url with the value, the url of the image to filter. GET /filteredimage?image_url={{URL}}
