Quick Start

Prerequisites

If you plan to work on apps/agent, use a current Node.js release that supports node --experimental-strip-types for that package's test script.

Setup

bash
# Install dependencies
pnpm install

# Seed the Next.js environment file used by `pnpm dev:web`
cp apps/web/.env.local.example apps/web/.env.local

# Seed the Wrangler/Worker environment file used by `pnpm preview`
# and by local Cloudflare-style bindings such as D1/cron vars
cp apps/web/.dev.vars.example apps/web/.dev.vars

# Add required local variables
$EDITOR apps/web/.env.local
# Add Worker/runtime variables when you need preview mode, agent admin flows,
# or parity with Cloudflare bindings
$EDITOR apps/web/.dev.vars
# Required beyond the example file:
# NEXT_PUBLIC_WALLETCONNECT_PROJECT_ID
#
# The example file already includes:
# NEXT_PUBLIC_POLY_BUILDER_CODE
# NEXT_PUBLIC_POLYMARKET_HOST
# NEXT_PUBLIC_POLYMARKET_WS_HOST
# NEXT_PUBLIC_POLYMARKET_CHAIN_ID
# POLY_RELAYER_API_KEY
# POLY_RELAYER_API_KEY_ADDRESS
#
# Common optional vars for local parity:
# NEXT_PUBLIC_APP_URL, NEXT_PUBLIC_POSTHOG_PROJECT_TOKEN,
# NEXT_PUBLIC_POSTHOG_HOST, POSTHOG_PROJECT_API_KEY, POSTHOG_HOST,
# OPENROUTER_API_KEY, EXTENSION_SESSION_SECRET,
# BUILDER_SIGNING_SERVER_URL, INTERNAL_AUTH_TOKEN,
# ALCHEMY_API_KEY, POLYGON_RPC_URL, COINMARKET_API_KEY

# Run the web app
pnpm dev:web

Open http://localhost:8000

pnpm dev:web reads apps/web/.env.local. pnpm preview and the Cloudflare Worker runtime read apps/web/.dev.vars, which is also where local D1/agent cron settings belong.

Extension Development

bash
# Configure the extension environment
cp apps/extension/.env.example apps/extension/.env

# Optional overrides:
# DEV_MODE=false        # point the built extension at production
# POLY_BUILDER_CODE=... # builder attribution code for extension orders
# WALLETCONNECT_PROJECT_ID=... # required for WalletConnect/mobile wallet QR flows

# Run the web app locally for extension API calls
pnpm dev:web

# In a second terminal, run the extension build in watch mode
pnpm dev:ext

In development, the extension targets http://localhost:8000 by default. Use DEV_MODE=false in apps/extension/.env if you want the built extension to talk to production instead.
