Node API 1 Project Starter Code

Introduction

• Building a RESTful API.
• Performing CRUD operations.
• Writing API endpoints.

Instructions

Task 1: Project Setup and Submission

Your assignment page on Canvas should contain instructions for submitting this project. If you are still unsure, reach out to School Staff.

Task 2: Minimum Viable Product

Use Node.js and Express to build an API that performs CRUD operations on users.

• Add a server script to the package.json that runs the API using nodemon.

Write endpoints

Add the code necessary in index.js and api/server.js to create a Web API and implement the following endpoints:

Method	URL	Description
POST	/api/users	Creates a user using the information sent inside the request body.
GET	/api/users	Returns an array users.
GET	/api/users/:id	Returns the user object with the specified id.
DELETE	/api/users/:id	Removes the user with the specified id and returns the deleted user.
PUT	/api/users/:id	Updates the user with the specified id using data from the request body. Returns the modified user

User Schema

Each User resource should conform to the following structure (AKA schema):

{
  id: "a_unique_id", // String, required
  name: "Jane Doe",  // String, required
  bio: "Having fun", // String, required
}

Database Access Functions

You can find them inside api/users/model.js. All of these functions return Promises.

• find Resolves to the list of users (or empty array).
• findById Takes an id and resolves to the user with that id (or null if the id does not exist).
• insert Takes a new user { name, bio } and resolves to the the newly created user { id, name, bio }.
• update Takes an id and an existing user { name, bio } and resolves the updated user { id, name, bio} (or null if the id does not exist).
• remove Takes an id and resolves to the deleted user { id, name, bio }.

Endpoint Specifications

When the client makes a POST request to /api/users:

• If the request body is missing the name or bio property:

  • respond with HTTP status code 400 (Bad Request).
  • return the following JSON response: { message: "Please provide name and bio for the user" }.

• If the information about the user is valid:

  • save the new user the the database.
  • respond with HTTP status code 201 (Created).
  • return the newly created user document including its id.

• If there's an error while saving the user:

  • respond with HTTP status code 500 (Server Error).
  • return the following JSON object: { message: "There was an error while saving the user to the database" }.

When the client makes a GET request to /api/users:

• If there's an error in retrieving the users from the database:
  • respond with HTTP status code 500.
  • return the following JSON object: { message: "The users information could not be retrieved" }.

When the client makes a GET request to /api/users/:id:

• If the user with the specified id is not found:

  • respond with HTTP status code 404 (Not Found).
  • return the following JSON object: { message: "The user with the specified ID does not exist" }.

• If there's an error in retrieving the user from the database:

  • respond with HTTP status code 500.
  • return the following JSON object: { message: "The user information could not be retrieved" }.

When the client makes a DELETE request to /api/users/:id:

• If the user with the specified id is not found:

  • respond with HTTP status code 404 (Not Found).
  • return the following JSON object: { message: "The user with the specified ID does not exist" }.

• If there's an error in removing the user from the database:

  • respond with HTTP status code 500.
  • return the following JSON object: { message: "The user could not be removed" }.

When the client makes a PUT request to /api/users/:id:

• If the user with the specified id is not found:

  • respond with HTTP status code 404 (Not Found).
  • return the following JSON object: { message: "The user with the specified ID does not exist" }.

• If the request body is missing the name or bio property:

  • respond with HTTP status code 400 (Bad Request).
  • return the following JSON response: { message: "Please provide name and bio for the user" }.

• If there's an error when updating the user:

  • respond with HTTP status code 500.
  • return the following JSON object: { message: "The user information could not be modified" }.

• If the user is found and the new information is valid:

  • update the user document in the database using the new information sent in the request body.
  • respond with HTTP status code 200 (OK).
  • return the newly updated user document.

Important Notes

• Test your work manually using Postman or HTTPie. Run automatic tests by executing npm test.
• You are welcome to create additional files but do not move or rename existing files or folders.
• Do not alter your package.json file except to install additional libraries or add additional scripts. Do not update existing libs.
• In your solution, it is essential that you follow best practices and produce clean and professional results.

Task 3: Stretch Problems

Be careful not to break MVP while working on these Stretch goals! If in doubt create a new branch.

You'll need to enable the cors middleware:

• add the cors npm module: npm i cors.
• add server.use(cors()) after server.use(express.json()).

Create a new React application and connect it to your server:

• the React application can be anywhere, but, for this project create it inside the folder for the solution.
• connect to the /api/users endpoint in the API and show the list of users.
• add a delete button to each displayed user that will remove it from the server.
• add forms to add and update data.
• Style the list of users however you see fit.
