Convert tsconfig to swc config.

> Why?

>

> (https://github.com/swc-project/swc/issues/1348)

>

> `swc` has no plans to support `tsconfig.json`, but it could be useful in some cases. For example, migrating from `tsc` to `swc` in a large project, you can use this tool to convert `tsconfig.json` to `.swcrc`, and then modify the `.swcrc` to make it work.

## Install

```bash

npm i tsconfig-to-swcconfig

```

## Usage

## Convert config in a tsconfig file

```typescript

import { convert } from 'tsconfig-to-swcconfig'

const swcConfig = convert() // will look for tsconfig under the cwd and convert it to swc config

```

Advanced options:

```typescript

import { convert } from 'tsconfig-to-swcconfig'

convert('tsconfig-filename.json', process.cwd(), {

  // more swc config to override...

  minify: true,

})

```

## Convert tsconfig value

Convert tsconfig value directly:

```typescript

import { convertTsConfig } from 'tsconfig-to-swcconfig'

const swcConfig = convertTsConfig({

  module: 'commonjs',

  target: 'es2018',

  strict: true,

  esModuleInterop: true,

})

```

Advanced usage:

```typescript

import { convertTsConfig } from 'tsconfig-to-swcconfig'

const swcConfig = convertTsConfig(

  { target: 'es2018' }, // tsconfig

  { minify: true }, // more swc config to override...

)

```

## CLI

To use the CLI, install globally:

```bash

npm i -g tsconfig-to-swcconfig

```

Then run:

```bash

tsconfig-to-swcconfig --help

```

```bash

Usage: tsconfig-to-swcconfig [options]

Alias: t2s [options]

Options:

  -f, --filename   filename to tsconfig (default: "tsconfig.json")

  -c, --cwd             cwd (default: process.cwd())

  -o, --output       output file (default: stdout)

  -s, --set =   set additional swcrc options

  -h, --help                 display help for command

```

Instead of installing globally, you can also use `npx` to run the CLI without installing:

```bash

npx tsconfig-to-swcconfig -f tsconfig.json -c /path/to/project -o swc.config.js

```
