Task was to build an API for a social network web application where users can share their thoughts, react to friends’ thoughts, and create a friend list. The required stack includes Express.js for routing, a MongoDB database, and the Mongoose ODM. In addition to using the Express.js and Mongoose packages, I have also used a native JavaScript Date object and Web API to format timestamps.

I have created a walkthrough video that demonstrates the functionality of the API using Insomnia after creating the API. A link to the video has been provided in the README below.

​Install dependencies using:

npm install

Need to have MongoDB and MongoDB Compass installed locally to run the app.

The application will then be invoked by using the following command:

npm run watch

• Node.js
• Express.js
• MongoDB
• Mongoose (ODM)

• Nodejs must be installed
• MongoDB Compass must be installed
• Insomnia was used to test routes
• Text editor (VS Code recommended)

This demos a general overview of the functionality of the api, and starts by demonstrating on how to invoke the application. I then explain how Mongoose syncs to MongoDB on server start, and go over the User and Thought models and their associated schemas and subdocuments. I also provide an brief over the getter method used to format dates, virtuals used, referenced models, self-references, and the objectId method to create a unique id value with a desired name:

This demos POST User, POST Thought, POST friend, POST Reaction, GET Single User, GET Single Thought, Get All Thoughts, GET All Users. This also showcases a match validation for an incorrect email and formatted dates:

/api/users

• GET all users
• GET a single user by its _id and populated thought and friend data
• POST a new user

/api/users/userId

• PUT to update a user by its _id

/api/users/:userId/friends/:friendId

• POST to add a new friend to a user's friend list

/api/thoughts

• GET to get all thoughts
• GET to get a single thought by its _id
• POST to create a new thought (This also pushes the created thought's _id to the associated user's thoughts array field)

/api/thoughts/:thoughtId/reactions

• POST to create a reaction stored in a single thought's reactions array field

This demos PUT Thought, POST friend (second), DELETE friend:

/api/thoughts/thoughtId

• PUT to update a thought by its _id

/api/users/:userId/friends/:friendId

• DELETE to remove a friend from a user's friend list

This demos DELETE Reaction, DELETE Thought, DELETE User (and associated thoughts):

/api/thoughts/:thoughtId/reactions

• DELETE to pull and remove a reaction by the reaction's reactionId value

/api/thoughts/thoughtId

• DELETE to remove a thought by its _id

/api/users/userId

• DELETE to remove user by its _id and removes a user's associated thoughts when deleted.
