Local Setup

The app depends on several third-party services and a pre-populated market data database. To run locally, you will need these two files:

• .env
• local.db

After cloning the repository, place both files in the project root:

spike-study/
  .env
  local.db
  package.json

Then install dependencies:

npm install

Run Locally

Start the SvelteKit app:

npm run dev

Open the local URL printed by Vite, usually http://localhost:5173.

The app is auth-protected, so sign in with a Google account.
