knip-it

knip is a tool for identifying redundant, unused code. knip-it does the following:

• accepts config details
• installs and runs knip
• uninstalls knip

This is what the default config looks like:

{
  "entry": ["src/index.tsx"],
  "project": ["src/**/*.tsx", "src/**/*.ts", "src/**/*.jsx", "src/**/*.js"]
}

Having ts and tsx also handles js and jsx.
