Serverless TODO

Simple TODO application using AWS Lambda and Serverless framework.

Functionality of the application

This application will allow creating/removing/updating/fetching/search TODO items. Each TODO item can optionally have an attachment image. Each user only has access to TODO items that he has created.

architecture

TODO items

The application should store TODO items, and each TODO item contains the following fields:

• todoId (string) - a unique id for an item
• createdAt (string) - date and time when an item was created
• name (string) - name of a TODO item (e.g. "Change a light bulb")
• dueDate (string) - date and time by which an item should be completed
• done (boolean) - true if an item was completed, false otherwise
• attachmentUrl (string) (optional) - a URL pointing to an image attached to a TODO item

You might also store an id of a user who created a TODO item.

Frontend

The client folder contains a web application that can use the backend API the project.

the config.ts file in the client folder contains an API endpoint and Auth0 configuration:

const apiId = '...' API Gateway id
export const apiEndpoint = `https://${apiId}.execute-api.us-east-1.amazonaws.com/dev`

export const authConfig = {
  domain: '...',    // Domain from Auth0
  clientId: '...',  // Client id from an Auth0 application
  callbackUrl: 'http://localhost:3000/callback'
}

How to run the application

Backend

To deploy an application run the following commands:

cd backend
npm install
sls deploy -v

Frontend

To run a client application first edit the client/src/config.ts file to set correct parameters. And then run the following commands:

cd client
npm install
npm run start

This should start a development server with the React application that will interact with the serverless TODO application.

Postman collection

An alternative way to test your API, you can use the Postman collection that contains sample requests. You can find a Postman collection in this project. To import this collection, do the following.

Click on the import button:

Click on the "Choose Files":

Select a file to import:

Right click on the imported collection to set variables for the collection:

Provide variables for the collection (similarly to how this was done in the course):
