Odin Frontend Tech Test

📗 Summary

Welcome to the Odin Frontend technical test!

This is a small challenge so that we can have an idea on how comfortable and fluent you're with React and modern Frontend technologies.

There are two parts to choose from, Part A & Part B, one is more UI oriented and the other involves a bit more logic. You only need to complete one part, choose the one you're more comfortable with. The recommended time block to complete the task is 3 hours.

Part A

The task is to implement the following page:

  • Make it mobile first
  • Handle the case for when the user has no investments (improvise the design)
  • Handle loading states and possible fetch failures
  • You do not need to build the navbar
  • The font is Mona Sans
  • Try to match the design, we value more if you think in terms of systems rather than just pixel perfection
  • When you run the server (see instruction below) you can get the data at localhost:8000/profile

Part B

If you choose part B, build an empty page with an "Edit" button, that when clicked opens a modal (or drawer) with the following form:

  • Do not implement any avatar upload, ignore the Upload new button
  • Submit the form by PATCH to http://localhost:8000/profile
  • Handle form submission failure
  • Add validation
    • Display name is required
    • Username is required and only letters or numbers are allowed (no symbols)
    • Bio is optional

💫 Tips

  • Make it mobile-first
  • Write small, single purpose components
  • Feel free to use fetch or any library (axios) to get/patch the data
  • Abstract re-usable components
  • Handle happy and unhappy paths
  • Clean code
  • Separation of concerns
  • Meaningful commit messages

💫 Bonus points

  • Create a theme from the current design
  • Type correctness
  • Write some integration or unit tests
    • (there's already a setup done for you in src/__tests__)
  • Make the application a11y friendly

☕️ Setup

Before you start, you will need:

Clone this repository, once cloned, install the package manager by running:

$ corepack enable

then install all the dependencies:

$ pnpm i

Next install json-server globally to be able to run the mock API:

# or `npm i -g json-server` if you're not familiar with PNPm globals
$ pnpm add -g json-server

Finally, run the development server:

$ pnpm dev

and the API (in a separate terminal tab):

$ json-server --watch data/db.json --port 8000

You can now access the app at localhost:3000 and the API on localhost:8000.

Other useful commands:

# To run the tests once
$ pnpm test
# To run the tests in watch mode
$ pnpm test:watch
# Lint the codebase
$ pnpm lint
# Check type safety
$ pnpm types
# Run the production build locally
$ pnpm build && pnpm start

The NextJS docs may be helpful if you hit any issues.

💬 Notes

Component library

Chakra UI is already setup for you in this project. We use Chakra heavily at Odin, so we encourage you to try it in this project. If you find this is a blocker for you, feel free to switch to something else, such as Tailwind or MUI.

Package manager

This repository is setup with pnpm. If you have issues while running the project locally, feel free use an alternative package manager like yarn or npm.

Typescript

In case you're not comfortable with Typescript, feel free to write Javascript. You'll just have to make this change in tsconfig.json:

- "strict": true,
+ "strict": false,

and work in .jsx files to get it working. Please note that at Odin, we only work in a typed environment, so any new joiner will be expected to learn it.
