tswc

Compile your TypeScript with tsconfig.json using swc

Install

npm install tswc @swc/core -D
# Or Yarn
yarn add tswc @swc/core --dev

Usage

Just change swc [...options] to tswc -- [options]. That's it! Your tsconfig.json file will be respected.

For example:

# Transpile one file and emit to stdout.
# swc FILE
tswc -- FILE

# Transpile one file and emit to `output.js`.
# swc FILE -o output.js
tswc -- FILE -o output.js

# Transpile and write output to dir
# swc DIR -d dir
tswc -- DIR -d dir

See more about how to use swc cli.

You can change your build script in "package.json" as:

"build": "tswc -- src -D dist",

Now you can run npm run build to build.

Notice

Only a subgroup of fields of tsconfig is supported currently. This is done with tsconfig-to-swcconfig. This means that some tsc features may be missing when compiling with this.

If you want to know what swc config is exactly used, you can use --debug to inspect:

tswc --debug -- [other options...]

Advanced Options

Options:
  --tsconfig <filename>  the filename of tsconfig (default: tsconfig.json)
  --debug                output the final swc config (default: false)
  -h, --help             Display this message
  -v, --version          Display version number
