I am currently using this package https://www.npmjs.com/package/js-beautify
like this:
import {js_beautify} from 'js-beautify';
const beautifiedCode = js_beautify(`
const foo = 'bar';
console.log(foo);
`)
however, imagine if I want to format the above, so that the maximum number of blank lines is one, so I want this:
const foo = 'bar';
console.log(foo);
unfortunately, I cannot find the docs on how to pass options to the programmatic API, I would guess it's something like this:
const beautifiedCode = js_beautify(`
const foo = 'bar';
console.log(foo);
`,
{maxBlankLines: 1}
)
but that's just a guess. How can I pass options to the programmatic API?
Beautifier can remove blank lines between tokens using the preserve_newlines: false
setting or limit the number of newlines using the max_preserve_newlines
with a number value such as max_preserve_newlines: 3
.
An example of API level usage is show in the Javascript section of the project README.md .
The configuration option names are the same as the CLI names but with underscores instead of dashes.
So to remove all empty lines:
import {js_beautify} from 'js-beautify';
const originalCode = `
const foo = 'bar';
console.log(foo);
`)
const beautifiedCode = js_beautify(originalCode, { preserve_newlines: false});
