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:

({
    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,
});
