In npm run scripts you can execute locally installed binaries by name. This enables the same for zx.
$`terser input.js --compress ecma=2015,computed_props=false`Note, that yarn and npm modify env.$PATH value, so some */node_modules/.bin binaries are available for invocation.
To disable this side-effect, append smth like PATH=$(env -i bash -c 'echo $PATH') to the command.
Evaluates target cmd as is without shq.
const cmd = 'echo foo'
const msg = 'bar'
const output = (await $.raw`${cmd} ${msg}`).toString().trim()
// $ echo foo barSince [email protected]
Set to false by default.
Applies .trim() to ProcessOutput string representation. Set true by default.
