# Migrating from Re.Pack 5

Re.Pack 6 raises the minimum supported versions of Node.js, React Native, Module Federation and Reanimated, and removes APIs that were deprecated in Re.Pack 5.

## Update dependencies in `package.json`

```diff
{
  "devDependencies": {
-    "@callstack/repack": "5.x.x"
+    "@callstack/repack": "^6.0.0"
  }
}
```

Update the Re.Pack plugins you use (`@callstack/repack-plugin-*`) to the same major version.

## Minimum supported versions

| Dependency                    | Re.Pack 5  | Re.Pack 6 |
| ----------------------------- | ---------- | --------- |
| Node.js                       | `>=18`     | `>=22.12` |
| React Native                  | `>=0.74`   | `>=0.82`  |
| `@module-federation/enhanced` | `>=0.6.10` | `>=2.0.0` |
| `react-native-reanimated`     | `>=3`      | `>=4`     |

## The legacy architecture is no longer supported

React Native 0.82 removed the legacy architecture, so Re.Pack's native module is now built only as a TurboModule. If your app still sets `newArchEnabled=false`, migrate it to the [New Architecture](https://reactnative.dev/architecture/landing-page) before upgrading.

## Package exports are enabled by default

`getResolveOptions()` now sets `enablePackageExports` to `true` by default, matching Metro's default since React Native 0.79. Configs that already pass `enablePackageExports: true` don't need changes. If your project relies on main-field resolution, opt out explicitly:

```diff
  resolve: {
-   ...Repack.getResolveOptions(),
+   ...Repack.getResolveOptions({ enablePackageExports: false }),
  },
```

See [Module Resolution](/docs/features/module-resolution.md#package-exports-conditional-exports) for how package exports change resolution.

## Module Federation V1 was removed

`ModuleFederationPluginV1` is no longer available, and `Repack.plugins.ModuleFederationPlugin` now points to [`ModuleFederationPluginV2`](/api/plugins/module-federation-v2.md). Follow [Migrating from V1](/docs/features/module-federation.md#migrating-from-v1) to move your configs to Module Federation 2.0.

The `Federated` helpers, which only worked with V1, were removed as well:

- `Federated.SHARED_REACT`, `Federated.SHARED_REACT_NATIVE` and `Federated.createRemote` from `@callstack/repack`
- `Federated.createURLResolver` and `Federated.importModule` from `@callstack/repack/client`

## Removed deprecated APIs

### `ChunksToHermesBytecodePlugin`

Use `HermesBytecodePlugin` instead. The options are the same.

```diff
- new Repack.plugins.ChunksToHermesBytecodePlugin({ ... })
+ new Repack.plugins.HermesBytecodePlugin({ ... })
```

### `getPublicPath`

Remove the call. Re.Pack configures `output.publicPath` out of the box.

```diff
  output: {
-   publicPath: Repack.getPublicPath({ platform, devServer }),
  },
```

### `--webpackConfig` CLI option

Use [`--config`](/api/cli/start.md#--config) instead.

```diff
- react-native start --webpackConfig webpack.config.js
+ react-native start --config webpack.config.js
```

### `@callstack/repack/commands/rspack` and `@callstack/repack/commands/webpack`

Use the unified commands. They pick the bundler based on the config file name, or the [`--bundler`](/api/cli/start.md#--bundler) option.

```diff title="react-native.config.js"
module.exports = {
-  commands: require('@callstack/repack/commands/rspack'),
+  commands: require('@callstack/repack/commands'),
};
```

### `OutputPlugin` output options

`output.bundleFilename`, `output.sourceMapFilename` and `output.assetsPath` had no effect since Re.Pack 5 and are now rejected by `OutputPlugin`'s option validation. Remove them and use the `--bundle-output`, `--sourcemap-output` and `--assets-dest` CLI options instead.

### `reanimatedModuleRules` from `@callstack/repack-plugin-reanimated`

Use `reanimated4ModuleRules` instead. `reanimatedModuleRules` was an alias of `reanimated3ModuleRules`, which was removed together with Reanimated 3 support (see below).

### Reanimated 3 support in `@callstack/repack-plugin-reanimated`

Reanimated 3 doesn't support React Native 0.82 or newer, so `ReanimatedPlugin` now requires `react-native-reanimated` 4 together with `react-native-worklets`, and `reanimated3ModuleRules` was removed. Follow the [Reanimated 4 migration guide](https://docs.swmansion.com/react-native-reanimated/docs/guides/migration-from-3.x/), then replace `react-native-reanimated/plugin` with `react-native-worklets/plugin` in your Babel config.
