Chainable if
!
Akua
is a very useful tools! It can solve your nested if-tree
, make it become chainable if
!
Akua
can help you code maintainable if!
Install
npm install akua --save
Use
normal nested if-tree
let normalIf = ''; const normailIfStart = new Date().getTime(); if (conditionA) { const tempA = 'tempA'; normalIf += 'a'; if (conditionB) { normalIf += 'b'; normalIf += tempA; if (conditionC) { normalIf += 'c'; if (conditionD) { normalIf += 'd'; if (conditionE) { normalIf += 'e'; } } } } else { normalIf += '!b'; } if (conditionF) { normalIf += 'f'; if (conditionG) { normalIf += 'g'; } } } else { normalIf += '!a'; }
akua if
let akuaIf = ''; const ifTree = new akua(); ifTree .inject(conditionA, 'a', (obj) => { obj.tempA = 'tempA'; akuaIf += 'a'; }) .inject(!conditionA, '!a', () => { akuaIf += '!a'; }) .inject(conditionB, 'a->b', (obj) => { akuaIf += 'b'; akuaIf += obj.tempA; }) .inject(!conditionB, 'a->!b', () => { akuaIf += '!b'; }) .inject(conditionC, 'b->c', () => { akuaIf += 'c'; }) .inject(conditionD, 'c->d', () => { akuaIf += 'd'; }) .inject(conditionE, 'd->e', () => { akuaIf += 'e'; }) .inject(conditionF, 'a->f', () => { akuaIf += 'f'; }) .inject(conditionG, 'f->g', () => { akuaIf += 'g'; }) .parse();
Finally, normalIf === akuaIf
, you can git clone this project and npm run test
if you doubt!
