tsconfig-to-swcconfig
Convert tsconfig to swc config.
Why?
(https://github.com/swc-project/swc/issues/1348)
swchas no plans to supporttsconfig.json, but it could be useful in some cases. For example, migrating fromtsctoswcin a large project, you can use this tool to converttsconfig.jsonto.swcrc, and then modify the.swcrcto make it work.
Install
npm i tsconfig-to-swcconfigUsage
Convert config in a tsconfig file
import { convert } from 'tsconfig-to-swcconfig'
const swcConfig = convert() // will look for tsconfig under the cwd and convert it to swc configAdvanced options:
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:
import { convertTsConfig } from 'tsconfig-to-swcconfig'
const swcConfig = convertTsConfig({
module: 'commonjs',
target: 'es2018',
strict: true,
esModuleInterop: true,
})Advanced usage:
import { convertTsConfig } from 'tsconfig-to-swcconfig'
const swcConfig = convertTsConfig(
{ target: 'es2018' }, // tsconfig
{ minify: true }, // more swc config to override...
