Getting Started

npm install @techor/one-liner

import oneLiner from '@techor/one-liner';
// or
import { l } from '@techor/one-liner';

l is equal to l

Strings

l`a ${true && 'b'} c`;
// 'a b c'

Objects

l`a ${{ b: true, c: false, d: isTrue() }} e`;
// 'a b d e'

Arrays

l`a ${['b', 0, false, 'c']} d`;
// 'a b c d'

Resolve types

l`a ${true} ${false} ${''} ${null} ${undefined} ${0} ${NaN} b`
// 'a b'

Trim and clear

• Remove newlines
• Convert consecutive spaces to one space

l`
    a
    b
    ${undefined}
    c    d
`
// 'a b c d'

Mixed and nested

l`
    a
    ${
        [
            1 && 'b',
            { c: false, d: null },
            ['e', ['f']]
        ]
    }
    g    h
`;
// 'a b e f g h'

Execute like a function

l`a b ${['c', 'd']} ${{ e: true, f: false }} ${true && 'g'}`;
