$ yarn add @ddoronin/super-objectIt's like
Object.assign(), but even more.
Usage
Suppose you compose a request to upload a file. You decided to set different content types based on a file extension and apply gzip if this a javascript or css file.
import { compose } from 'super-object';
...
function createRequest(payload: any, fileExt: string) {
return api.compose({
body: { ...payload }
}).if(fileExt === '.js', {
contentType: 'text/javascript'
}).elseif(fileExt === '.css', {
contentType: 'text/css'
}).else({
contentType: 'application/octet-stream'
}).if(fileExt === '.js' || fileExt === '.css', {
encoding: 'gzip'
}).val();
