API
import {minify} from '@putout/minify';
minify(`
const a = 5;
const b = 6;
fn(a, b);
`);// returns
var a=5,b=6;fn(a,b);Options
You can also pass options to minify. Here is list of default options:
({
quotes: `'`,
fixCount: 1, // the more fixCount - less output size
conditions: false,
mangleClassNames: true,
mangle: true,
mergeVariables: true,
removeUnusedVariables: false,
removeConsole: false,
removeUselessSpread: true,
applyTemplateLiterals: true,
convertStrictEqualToEqual: false,
});And usage example:
import {minify} from '@putout/minify';
const source = `
const a = 5;
const b = 6;
`;
minify(source, {
removeUnusedVariables: false,
});How it's compared to X(your benchmark)?
