## Overview

We are very excited to announce the release of @general-translation/compiler v1.0.0.

As we stated in our `gt-next@6.2.0` release, we believe the future of i18n libraries lies in build-time processing. Earlier this year, we released an SWC plugin for `gt-next` that enabled optimisations such as compile-time hashing and improved string translation during development. While this gave our team an excellent (albeit intense) introduction to compiler plugins, its scope was limited to Next.js projects.

We're following through on our commitment to build-time processing by releasing this general-purpose React compiler plugin. This means all the build-time optimisations from `gt-next` are now available to every `gt-react` user!

## Setup

### Configuration

| Option               | Type    | Default  | Description                                                                                   |
| -------------------- | ------- | -------- | --------------------------------------------------------------------------------------------- |
| `compileTimeHash`    | boolean | `true`   | Enables compile-time hashing                                                                  |
| `disableBuildChecks` | boolean | `false`  | Prevents errors from being thrown when invalid library usage is detected                      |
| `logLevel`           | string  | `'warn'` | Controls the logging level. Options: `'silent'` | `'error'` | `'warn'` | `'info'` | `'debug'` |

**Note**:
For `gt-next`, to satisfy a backwards-compatibility requirement, if you set `compileTimeHash` to `false`, the entire plugin will be disabled.

### gt-react

First, install the package:

```bash
npm install @generaltranslation/compiler
```

**Vite**

```js
// vite.config.js
import { defineConfig } from 'vite'
import { vite as gtCompiler } from '@generaltranslation/compiler'

export default defineConfig({
  plugins: [gtCompiler()],
})
```

**Webpack**

```js
// webpack.config.js
const { webpack: gtCompiler } = require('@generaltranslation/compiler')

module.exports = {
  plugins: [gtCompiler()],
}
```

**Rollup**

```js
// rollup.config.js
import { rollup as gtCompiler } from '@generaltranslation/compiler'

export default {
  plugins: [gtCompiler()],
}
```


### gt-next

You do not need to install any additional packages.

For `gt-next`, we're deprecating `experimentalSwcPluginOptions` in favour of the new `experimentalCompilerOptions` field. The main difference is that you must now specify which compiler type to use: `'swc'` or `'babel'`. The `'swc'` compiler is used by default, but you can enable the new Babel-based compiler by setting the `type` field to `'babel'`.

```js
// next.config.js
import { withGTConfig } from 'gt-next'

export default withGTConfig(nextConfig, {
  experimentalCompilerOptions: {
    type: 'babel',
  },
})
```


## Conclusion

We have much more work planned for the compiler, so expect frequent updates over the coming months.
