Project Instructions

Introduction

In this project you will be given a set of requirements and must design a database to satisfy them. As a part of this process you'll also build an API with endpoints to access the data.

Files to Complete

1. package.json
2. index.js
3. api/server.js
4. model.js inside api/project, api/resource and api/task
5. router.js inside api/project, api/resource and api/task
6. migration file(s)
7. seed file(s) optional

Required Dependencies

The project needs some additional NPM dependencies in order to work.

Required Scripts

Add "start". "server", "migrate" and "rollback" scripts to the package.json file. The tests depend on these scripts being correct!

Required Tables

Build the migration(s) in Knex inside the data/migrations folder using appropriate data types and constraints. You must use the table names and the column names described below. To give a primary key a name different than id, do table.increments("project_id") instead of table.increments().

• A project is what needs to be done and is stored in a projects table with the following columns:

  • project_id - primary key
  • project_name - required
  • project_description - optional
  • project_completed - the database defaults it to false (integer 0) if not provided

• A resource is anything needed to complete a project and is stored in a resources table with the following columns:

  • resource_id - primary key
  • resource_name - required and unique
  • resource_description - optional

• A task is one of the steps needed to complete a project and is stored in a tasks table with the following columns:

  • task_id - primary key
  • task_description - required
  • task_notes - optional
  • task_completed - the database defaults it to false (integer 0) if not provided
  • project_id - required and points to an actual project_id in the projects table

• A resource assignment connects a resource and a project, and is stored in a project_resources table. You decide what columns to use.

Required Endpoints

Build an API inside the api folder with endpoints for:

• [POST] /api/resources

  • Example of response body: {"resource_id":1,"resource_name":"foo","resource_description":null}

• [GET] /api/resources

  • Example of response body: [{"resource_id":1,"resource_name":"foo","resource_description":null}]

• [POST] /api/projects

  • Even though project_completed is stored as an integer, the API uses booleans when interacting with the client
  • Example of response body: {"project_id":1,"project_name":"bar","project_description":null,"project_completed":false}

• [GET] /api/projects

  • Even though project_completed is stored as an integer, the API uses booleans when interacting with the client
  • Example of response body: [{"project_id":1,"project_name":"bar","project_description":null,"project_completed":false}]

• [POST] /api/tasks

  • Even though task_completed is stored as an integer, the API uses booleans when interacting with the client
  • Example of response body: {"task_id":1,"task_description":"baz","task_notes":null,"task_completed":false,"project_id:1}

• [GET] /api/tasks

  • Even though task_completed is stored as an integer, the API uses booleans when interacting with the client
  • Each task must include project_name and project_description
  • Example of response body: [{"task_id":1,"task_description":"baz","task_notes":null,"task_completed":false,"project_name:"bar","project_description":null}]

Important Notes:

• Run tests locally by executing npm run test. Tests will be very broken until you flesh out the project sufficiently.
• You are welcome to create additional files for middlewares etc, but do not move or rename existing files or folders.
• Do not make changes to your package.json except to add additional dependencies and scripts. Do not update existing packages.
• Delete test.db3 and database.db3 and re-run migrations and tests, if you suspect half-finished code left your databases in a broken state.
• In your solution, it is essential that you follow best practices and produce clean and professional results.
• Schedule time to review, refine, and assess your work and perform basic professional polishing.
