# bundle

Turns a generated Vovk.ts TypeScript client into a dependency-free npm package with JS, types, package.json and a README. Useful when the client has to leave the app and land in a registry.

## What it does

The skill covers the `vovk bundle` command from Vovk.ts. Vovk first writes the client into `prebundleOutDir` (default `tmp_prebundle`), then hands control to your async `bundle.build({ entry, outDir, prebundleDir })`, where any bundler can be plugged in. After that Vovk emits `package.json` and a README with samples into `outDir` (default `dist`) and wipes the temporary folder unless `keepPrebundleDir: true` is set.

Only `tsdown` was tested by the authors, and they advise pinning `tsdown@0.23.0` until newer releases are confirmed to work. Compilation runs in two passes: one for code, one for declarations only. `origin` is required in `outputConfig` — it is the API base URL baked into the client. Setting `imports.validateOnClient: null` drops AJV checks on the client side and cuts the package size noticeably. Note that `includeSegments` and `excludeSegments` sit on the root `bundle` config, not inside `outputConfig`.

This is TypeScript only. Python and Rust clients have their own templates and separate skills. Running `vovk bundle` during everyday development is a waste — `vovk generate` is faster and keeps the client inside the project. Reach for the bundle when you actually need a registry artifact.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add finom/vovk --skill bundle -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add finom/vovk --skill bundle -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add finom/vovk --skill bundle -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install finom/vovk bundle
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add finom/vovk --skill bundle -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/finom/vovk --path skills/bundle
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add finom/vovk --skill bundle -a opencode
```

### Claude.ai

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

## When to use it
- package a Vovk.ts client as a zero-dependency npm module
- wire tsdown into the client build without losing type declarations
- shrink the published package by disabling client-side AJV validation
- add custom exports and a README banner to the generated package
- filter out API segments that should not ship in the SDK

## Example prompts
- Bundle the Vovk client into a publishable package and show me what lands in `dist`
- Set up `bundle.build` with `tsdown@0.23.0` and the two-pass build
- Turn off `imports.validateOnClient` and tell me how much smaller the bundle gets

# Vovk.ts `vovk bundle`

`vovk bundle` packages composed TypeScript client as zero-dep npm package — pre-built JS + `.d.ts`, auto-gen `package.json`, auto-gen `README.md` w/ samples, ready for `npm publish`. Release step: `vovk generate` → in-project client for dev; `vovk bundle` → distributable SDK installed from registry.

**TypeScript-only.** Despite name, ships no Python/Rust clients. Those have own templates (`py` / `pySrc` / `rs` / `rsSrc`) and own publish flows — see **`python`** and **`rust`** skills.

## `bundle` vs `generate`

| Command | Purpose | Output | When |
|---|---|---|---|
| `vovk generate` | In-project TypeScript client + OpenAPI spec | `src/client/` (or `client/` without `src/app`), `.vovk-schema/` | Every build (`prebuild` hook), on schema changes during `vovk dev`. |
| `vovk bundle` | Publishable npm package — pre-built JS + `.d.ts` + `package.json` + `README.md` | `dist/` ready for `npm publish` | Ship SDK outside Next.js app. |

Don't run `vovk bundle` in normal dev; in-project client faster. Bundle when you need registry artifact.

## How bundling works

1. Vovk gens TypeScript client into `prebundleOutDir` (default `tmp_prebundle`) via `tsBase` template — uncompiled `.ts` source.
2. Vovk calls your `bundle.build({ entry, outDir, prebundleDir })` async fn. Plugs in any bundler (tsdown only tested one) to compile `entry` (the `tmp_prebundle/index.ts`) → JS + `.d.ts` under `outDir` (default `dist`).
3. Vovk emits `package.json` and `README.md` from `packageJson` and `readme` templates into `outDir`.
4. Vovk deletes `prebundleOutDir` unless `keepPrebundleDir: true` (handy for debugging prebundled source).

```sh
npx vovk bundle
npm publish dist
```
