[npm-url]: https://www.npmjs.com/package/@kinobi-so/renderers-js

This package generates JavaScript clients from your Kinobi IDLs. The generated clients are compatible with the soon-to-be-released 2.0 line of [`@solana/web3.js`](https://github.com/solana-labs/solana-web3.js).

## Installation

```sh
pnpm install @kinobi-so/renderers-js
```

> [!NOTE]
> This package is **not** included in the main [`kinobi`](../library) package.
>
> However, note that the [`renderers`](../renderers) package re-exports the `renderVisitor` function of this package as `renderJavaScriptVisitor`.

## Usage

Once you have a Kinobi IDL, you can use the `renderVisitor` of this package to generate JavaScript clients. You will need to provide the base directory where the generated files will be saved and an optional set of options to customize the output.

```ts
// node ./kinobi.mjs
import { renderVisitor } from '@kinobi-so/renderers-js';

const pathToGeneratedFolder = path.join(__dirname, 'clients', 'js', 'src', 'generated');
const options = {}; // See below.
kinobi.accept(renderVisitor(pathToGeneratedFolder, options));
```

## Options

The `renderVisitor` accepts the following options.

| Name                          | Type                                                                                                                    | Default | Description                                                                                                                                                                                                                                                     |

When set to `false` (default), only the instruction leaves are being rendered.                                                                                         |

When set to `true`, the main `@solana/web3.js` library is used which enables generated clients to install it as a `peerDependency`. |
