# tauri-plugin-hdiff-update

Tauri v2 plugin for signed HDiffPatch differential installer updates.

## Install

```toml
[dependencies]
tauri-plugin-hdiff-update = "0.1"
```

Register the plugin:

```rust
tauri::Builder::default()
    .plugin(tauri_plugin_hdiff_update::init())
```

Enable the production permission set:

```json
"hdiff-update:default"
```

The default permission only exposes the production update path:

- `download_and_apply`
- `download_and_install`

The release-lab commands are intentionally excluded from the default permission
set.

## Frontend Command

```ts
import { Channel, invoke } from "@tauri-apps/api/core";

const onEvent = new Channel();
onEvent.onmessage = (event) => console.log(event);

await invoke("plugin:hdiff-update|download_and_install", {
  options: {
    update: {
      manifestUrl: "https://updates.example.com/latest.json",
      currentVersion: "0.1.0",
      currentArtifactPath: "C:\\ProgramData\\xCodex\\installers\\xCodex_0.1.0.exe",
      hpatchzPath: "C:\\Program Files\\xCodex\\resources\\bin\\hpatchz.exe",
      signaturePublicKey: "base64-ed25519-public-key",
      requireSignature: true,
      headers: [{ name: "Authorization", value: "Bearer short-lived-token" }],
    },
    installerArgs: [],
  },
  onEvent,
});
```
