# Description of Changes
Adds a new Next.js quickstart template and documentation.
**New Template (`templates/nextjs-ts/`):**
- Next.js 15 App Router with TypeScript SpacetimeDB module
- Pre-configured `SpacetimeDBProvider` with client-side connection
handling
- Environment variable support (`NEXT_PUBLIC_SPACETIMEDB_HOST`,
`NEXT_PUBLIC_SPACETIMEDB_DB_NAME`)
- SSR-safe implementation with `"use client"` directives
- Example page demonstrating `useTable` and `useReducer` hooks
- Dev server runs on port 3001 to avoid conflict with SpacetimeDB on
port 3000
- Pre-generated module bindings included
**New Documentation (`docs/.../00200-nextjs.md`):**
- 8-step quickstart consistent with other quickstarts (React,
TypeScript, Rust, C#)
- Covers: project creation, structure, tables/reducers, CLI testing
- Next.js-specific: provider pattern, SSR considerations, env var
configuration, React hooks usage
**Updated `templates-list.json`:**
- Added `nextjs-ts` to highlights and templates list
# API and ABI breaking changes
None.
# Expected complexity level and risk
1 - Adds a new template and docs without modifying existing
functionality.
# Testing
- [ ] Run `spacetime dev --template nextjs-ts my-test-app` and verify
the app starts
- [ ] Navigate to http://localhost:3001 and confirm the UI loads and
connects
- [ ] Add a person via the UI and verify it appears in the list
- [ ] Verify env vars work: set `NEXT_PUBLIC_SPACETIMEDB_URI` and
`NEXT_PUBLIC_SPACETIMEDB_MODULE`
- [ ] Verify the quickstart doc renders correctly in the docs site
- [ ] Confirm Next.js appears in the sidebar after React
