michaelfoss/ipo-calendar

A calendar for looking up IPOs.

Vise Finnhub Calendar

Quick Setup

• npm i
• Copy .env.sample to .env and add API keys
• npm start
• Fire up http://localhost:3000/!

Additional Scripts

• npm test to run some unit tests (will hit Finnhub)
• npm lint if you want to lint the project's code
• npm lint:fix if you want to lint and fix the project's code

Caveats

• Tested on latest Chrome, but not much else. YMMV.
• Desktop works fine.
• Any IPOs retrieved from Finnhub which do not have a Symbol are ignored.

Focus Points

• Architecture
• Functionality
• Caching of API request data
• Restriction of user interaction of app while fetching data
• Unit tests of utility functions (incomplete, but something to prove they're working)
• Proper environment setup for future development

Things Left To Do

• Styling, animations, etc.
• Responsive design (looks good on Desktop, is usable on tablet/mobile)

Bonus Features

• ✔️ Allow switching between time interval shown - i.e. implement day, week, and month calendar views
• ❌ Allow filtering events shown by exchange, price, etc.
• ❌ Add company earnings release events with Finnhub's earnings calendar API endpoint
• ❌ Allow users to add their own events, add notes on events, and/or "highlight"/"favorite" events
• ❌ Persist these inputs across sessions
• ❌ Any other polish or useful enhancements/features you can think of. Feel free to be creative!

Key Takeaways

• How long you spent on the exercise: Literally days.
• What you would change if you were to do it again:
  • Request more time. This project is not really doable in 3.5 hours if you want to submit something of quality.
  • Toss the project provided. I spent too much time trying to fit my own environment stuff in (Jest, Babel, etc.) when I could've used a project I've used in the past and stripped it down to a template.
• Anything else we should note:
  • Solving problems like these are fun! Even struggling with some of the challenges such as environment issues and requirements stretch me and allow me to learn something new every time.
  • Your Instructions.md references the same Finnhub URL twice on lines 15 & 16.
  • Each of the "Bonus Feature" are great ideas, but are not reasonable stretch goals given the limited timeframe.
