Node.js Coding Challenge

The purpose of this coding challenge is to gauge knowledge in Node.js and TypeScript. In the coding challenge, you will build a Node.js api interface that an end user can consume to get a small subset of Aumni data.

We have provided a basic TypeScript boilerplate app that provides a server, PostgreSQL database, and testing harness. Please feel free to move things around according to your preference, e.g., moving the health check to your preferred file structure.

Terminology

Some helpful terminology to help you understand the domain-specific terms:

• Fund - A Fund is a type of Investment Vehicle that invests the money that it has raised into various Companies.
• Company - A Company that a Fund invests in. Traditionally called a Portfolio Company from the perspective of the Fund. This is typically a start-up company that is trying to raise money.

Setup/Notes

1. Clone/Download this repository. We have seeded some data for you in the database.

2. Checkout branch and name it after yourself.

3. Make your first commit by filling out the code-challenge-notes.md file in the root of this directory.

4. Once you have made your first commit you will have 72 hours to make your final commit to complete the code challenge.

5. Please do NOT push your code challenge solution to a public repository.

6. This is a backend coding challenge. Please do NOT spend your time building out any kind of frontend UI.

7. You are allowed to install and use third-party packages.

Getting Started

1. Ensure PostgreSQL is installed and running on your machine. Note: You may need to create the postgres user, i.e., createuser -s postgres
2. Run yarn to install dependencies.
3. Run yarn seed to create and seed the database.
4. Run yarn start to start the server. The default URL and Port is http://localhost:3000.

Goals

• Build out 4 endpoints.
• /funds/ - Will return all funds and companies data
• /funds/:id - Will return a specific fund
• /funds/:id/:companyId - Will return a specific fund and company data
• /funds/:id/?minCost=100&maxCost=100000 - Filter the companies for a specific fund

Example of an Endpoint Schema Structure

For an endpoint like /funds/1/33, you would return a response:

{
  "id": 1,
  "name": "Hodkiewicz-Veum Ventures",
  "companies": [
    {
      "id": 62,
      "name": "Hauck Infrastructure Inc.",
      "logo": "https://via.placeholder.com/200",
      "cost": 9638817,
      "ownershipPercentage": 0.06402042802555542,
      "impliedValue": 61708119,
      "founded": "2012-10-28"
    }
  ]
}

Stretch Goals

• Setup and implement authentication with your endpoints
• Logging
• Expand the data set
• Additional comprehensive filters on companies and/or funds

Acceptance Criteria

• You have filled out the required parts of the code-challenge-notes.md and made your first commit.
• The code is well organized.
• The code follows Node.js/TypeScript best practices.
• Your Git commit history is clean and meaningful.
• The code should be free of linting errors.
• You should have passing unit tests for at least one route.

Submission

1. When you have your final commit complete, please zip up your entire folder.
2. We use Breezy as our ATS (Applicant Tracking System), you should have received and email with a link to Breezy to submit your zip file. If you did not get the email or can't find it, reach out to recruiting_eng@aumni.fund for a new link.
