Sprint Challenge: Express and Node.js - Projects & Actions

Description

In this challenge, you design and create a web API to manage the following resources: Projects and Actions.

Instructions

Read these instructions carefully. Understand exactly what is expected before starting to code.

This is an individual assessment, please work on it alone. It is an opportunity to demonstrate proficiency of the concepts and objectives introduced and practiced in preceding days.

If the instructions are not clear, please seek support from your TL and Instructor on Slack.

The Minimum Viable Product must be completed in three hours.

Follow these steps to set up and work on your project:

• Create a forked copy of this project.
• Add your Team Lead as collaborator on Github.
• Clone your forked version of the Repository.
• Create a new Branch on the clone: git checkout -b firstName-lastName.
• Implement the project on this Branch, committing changes regularly.
• Push commits: git push origin firstName-lastName.

Follow these steps for completing your project.

• Submit a Pull-Request to merge firstName-lastName Branch into main on your fork, don't make Pull Requests against Lambda's repository.
• Please don't merge your own pull request.
• Add your Team Lead as a Reviewer on the Pull-request
• Your Team Lead will count the challenge as done by merging the branch into main.

Commits

Commit your code regularly and use descriptive messages. This helps both you (in case you ever need to return to old code) and your Team Lead.

Self-Study/Essay Questions

Demonstrate your understanding of this Sprint's concepts by answering the following free-form questions. Edit this document to include your answers after each question. Make sure to leave a blank line above and below your answer so it is clear and easy to read by your Team Lead.

• Mention two parts of Express that you learned about this week.

• Describe Middleware?

• Describe a Resource?

• What can the API return to help clients know if a request was successful?

• How can we partition our application into sub-applications?

Minimum Viable Product

• Configure an npm script named "server" that will execute your code using nodemon. Make nodemon be a development time dependency only, it shouldn't be deployed to production.
• Configure an npm script named "start" that will execute your code using node.

Design and build the necessary endpoints to:

• Perform CRUD operations on projects and actions. When adding an action, make sure the project_id provided belongs to an existing project. If you try to add an action with an id of 3 and there is no project with that id the database will return an error.
• Retrieve the list of actions for a project.

Please read the following sections before implementing the Minimum Viable Product, they describe how the database is structured and the files and methods available for interacting with the data.

Database Schemas

The description of the structure and extra information about each resource stored in the included database (./data/lambda.db3) is listed below.

Projects

Actions

Database Persistence Helpers

The /data/helpers folder includes files you can use to manage the persistence of project and action data. These files are projectModel.js and actionModel.js. Both files publish the following api, which you can use to store, modify and retrieve each resource:

All these helper methods return a promise. Remember to use .then().catch() or async/await.

• get(): resolves to an array of all the resources contained in the database. If you pass an id to this method it will return the resource with that id if one is found.
• insert(): calling insert passing it a resource object will add it to the database and return the newly created resource.
• update(): accepts two arguments, the first is the id of the resource to update, and the second is an object with the changes to apply. It returns the updated resource. If a resource with the provided id is not found, the method returns null.
• remove(): the remove method accepts an id as it's first parameter and, upon successfully deleting the resource from the database, returns the number of records deleted.

The projectModel.js helper includes an extra method called getProjectActions() that takes a project id as it's only argument and returns a list of all the actions for the project.

We have provided test data for all the resources.

Please ignore any terminal warnings about returning() not supported by SQLite.

Stretch Goal

• Use create-react-app to create an application in a separate folder (outside the API project folder). Name it anything you want.
• From the React application show a list of all projects using the API you built.
• Add functionality to show the details of a project, including its actions, when clicking a project name in the list. Use React Router to navigate to a separate route to show the project details.
• Add styling!
