Solid Rollup Preset

# Solid Rollup Preset

A small opinionated preset for rollup to bundle your [solid](https://github.com/ryansolid/solid) libraries with rollup.

Features out of the box:

- Automatic TypeScript
- Minimal - two lines config
- No lock-in - you are in total control of the rollup config
- Best practices for publishing solid libraries by compiling for `esm`, `cjs`, `jsx`, `umd` and `tsc`
- Automatically clean `dist` folder on build

## Usage

1. Install with your favorite package manager:

```sh
npm install -D rollup-preset-solid rollup
pnpm add -D rollup-preset-solid rollup
yarn add -D rollup-preset-solid rollup
```

2. Import `withConfig` in your `rollup.config.js`. The first and only argument is (optionally) your rollup config:

```js
// rollup.config.js
import withSolid from "rollup-preset-solid";

export default withSolid();
```

3. Configure your package.json

```json
{
"name": "my-lib",

"// This is optional but this remove the need to manually configure the source input for rollup": "",
"source": "src/my-lib.tsx",

"// All the following properties will be hinted during build": "",
"// You will just have to copy paste them": "",

"main": "dist/cjs/my-lib.js",
"module": "dist/esm/my-lib.js",
"types": "dist/types/my-lib.d.ts",
"files": ["dist"],
"exports": {
".": {
"solid": "./dist/source/my-lib.jsx",
"import": "./dist/esm/my-lib.js",
"browser": "./dist/esm/my-lib.js",
"require": "./dist/cjs/my-lib.js",
"node": "./dist/cjs/my-lib.js"
}
}
}
```

## API

### withSolid(options?: Options | Options[]): RollupOptions | RollupOptions[]

The default export. A wrapper function that accepts all of the rollup options and a few extra to configure what to generate.

### Options

The options are the exact same as Rollup with a few extra that are
specific to the wrapper

#### Interface

```ts
interface Options extends RollupOptions {
/**
* Defines which target you want
* @default ['esm']
*/
targets?: ModuleFormat[];
/**
* Whether to generate a package.json or not
* This is useful for sub packages
* @default false
*/
writePackageJson?: boolean;
/**
* Whether to hint what to put in your package.json or not
* @default false
*/
printInstructions?: boolean;
}
```

#### Example

```js
// rollup.config.js
import withSolid from "rollup-preset-solid";

export default withSolid([
{ input: "browser.ts", targets: ["esm"] },
{ input: "server.ts", targets: ["esm", "cjs"], writePackageJson: true },
]);
```
