- closes fix: lazy-load @reown/appkit to reduce initial bundle size #492 (branch with signed commits)
@stacks/connect has two top-level imports from @reown/appkit-universal-connector
and @reown/appkit/networks. These cause consumer bundlers (Next.js, Webpack,
Vite) to eagerly resolve the entire @reown/appkit dependency tree — including
Lit UI components (@reown/appkit-ui, @reown/appkit-scaffold-ui, @reown/appkit-pay,
@reown/appkit-siwx) that @stacks/connect never renders — into the initial
JavaScript bundle. When bundled and minified, this adds ~1.7MB of JavaScript
that must be downloaded, parsed, and executed on every page load, even if
WalletConnect is never used. It also causes "Lit is in dev mode" warnings
during SSR.
Changes:
- request.ts: import → import type for UniversalConnectorConfig
(type-only usage, erased at compile time)
- walletconnect/config.ts: inline Bitcoin CAIP network objects,
removing import { bitcoin } from @reown/appkit/networks
- walletconnect/index.ts: dynamic import() for UniversalConnector
inside the already-async initializeWalletConnectProvider
- tsup.config.ts: explicitly externalize @reown packages
The @reown/appkit code is now only loaded when a user actually clicks
WalletConnect — not on every page load.
