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:
- The Simple Frontend A basic Ionic client web application which consumes the RestAPI Backend. [Covered in the course]
- The RestAPI Backend, a Node-Express server which can be deployed to a cloud service. [Covered in the course]
- 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:
- Initialize a new project:
npm i - 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.
