## What it does

The skill starts from your `package.json`, works out the framework and its major version, then loads the matching reference: `references/nextjs.md` with `webDir` `out` for Next.js, `.output/public` for Nuxt, `dist/<project>/browser` for Angular, `build` or `dist` for SvelteKit. It fixes the usual failures — `npx cap sync` complaining that the assets directory has no `index.html`, or a white screen right after sync.

Before touching config it greps for server-only code: `app/api/`, `middleware.ts`, `'use server'`, `getServerSideProps`, `+page.server.ts`, `@angular/ssr`. Capacitor never runs Node, so SSR, API routes and server actions simply do not exist in the app. The skill lists them and agrees with you on where each one goes — external API, client fetch or native plugin — before anything is deleted.

Then it installs `@capacitor/core`, `@capacitor/ios`, `@capacitor/android` and `@capacitor/cli`, runs `npx cap init` with your `webDir`, adds both platforms and suggests a single `build:mobile` script that builds and syncs. Two things to plan for: Capacitor 8 needs Node 22+, SvelteKit 3 raises that to Node 22.17, and env variables such as `NEXT_PUBLIC_*` or `VITE_*` are inlined at build time, so every `cap sync` needs a fresh build and production must not point at `localhost`.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill framework-to-capacitor -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/framework-to-capacitor/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/framework-to-capacitor/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill framework-to-capacitor -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/framework-to-capacitor/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill framework-to-capacitor -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/framework-to-capacitor/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Cap-go/capgo-skills framework-to-capacitor
```

2. **Manually: put the files in place**
- File: `.github/skills/framework-to-capacitor/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill framework-to-capacitor -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/Cap-go/capgo-skills --path skills/framework-to-capacitor
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/framework-to-capacitor/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add Cap-go/capgo-skills --skill framework-to-capacitor -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/Cap-go/capgo-skills/tree/HEAD/skills/framework-to-capacitor/SKILL.md

## When to use it
- fix `cap sync` failing on a missing `index.html`
- get rid of the white screen after sync
- find server routes that cannot run inside the app
- match `webDir` to the framework's real output folder
- make build and sync a single command

## Example prompts
- set up my Next.js build for Capacitor, I get a white screen after cap sync
- check which API routes and middleware won't work in the mobile app
- add a build:mobile script that builds the project and runs cap sync

description: Configures a web framework build so Capacitor can ship it as an iOS/Android app. Use for Next.js static export (output 'export', out/), Nuxt 4 (ssr false, nuxt generate, .output/public), Angular (dist/<project>/browser), SvelteKit adapter-static (SvelteKit 2 svelte.config.js or SvelteKit 3 vite.config), React/Vue/Svelte/Solid on Vite, and React Router framework SPA mode. Covers webDir mismatch, blank white screen after cap sync, missing index.html, SSR/API routes/middleware/server actions that cannot run in the app, next/image errors, deep-link reloads landing on the home page, router base paths, and env variables. Do not use for whole-app store readiness (webapp-to-capacitor), Cordova projects (cordova-to-capacitor), Capacitor major upgrades (capacitor-app-upgrades), or UI kits (ionic-design, konsta-ui, tailwind-capacitor).

# Framework to Capacitor

Make a framework emit a static bundle that Capacitor can copy into the native projects, and wire the scripts so `build -> cap sync` is one step.

## When to Use

TRIGGER when:
- Adding Capacitor to a Next.js, Nuxt, Angular, SvelteKit, Vite (React/Vue/Svelte/Solid), React Router, Qwik, or Astro project.
- `npx cap sync` fails with `The web assets directory (./dist) must contain an index.html file.` or `Could not find the web assets directory: ./dist.`
- The app launches to a white screen or loads the wrong page after a reload or deep link.
- The framework build fails because of SSR-only features (`output: 'export'` errors, `prerender` errors, API routes, middleware, server actions).

Do not use for:
- Store readiness, native UX, permissions, billing, review risk -> `webapp-to-capacitor`, `capacitor-app-store`, `capacitor-apple-review-preflight`.
- Cordova/PhoneGap apps -> `cordova-to-capacitor`.
- Capacitor version upgrades -> `capacitor-app-upgrades`.
- Live updates setup -> `capgo-live-updates`.
