quick-remap

A simple mapping library for when you just need to do a quick renaming of certain fields on objects, while leaving everything else as is.

The only export of the library is the function quickMapping which has the following header:

quickMapping = (source: any, keysToRename: any, keysToSkip?: string[]): any

keysToRename: a simple object which has as it's keys the key in the source object you want to remap and the value for the key the new name.

keysToSkip: an optional array for keys you just want to skip.

Example

A basic example

let source = { name: "John", lastName: "Smith", "clientId": 1 };
let final = quickMapping(source, {"name":"firstName"});
console.log(final); // { firstName: "John", lastName: "Smith", "clientId": 1 };

A basic example with deletion

let source = { name: "John", lastName: "Smith", "clientId": 1 };
let final = quickMapping(source, {"name":"firstName"}, ["clientId"]);
console.log(final); // { firstName: "John", lastName: "Smith" };

A basic example with arrays

    let source = [{ name: "John", lastName: "Smith", "clientId": 1 }, { name: "George", lastName: "Smith", "clientId": 2 }];
    let final = source.map(c => quickMapping(c, {"name":"firstName"}))

Important

The function will do a deep copy of the object, the library has been tested in the context of typescript and node, not plain javascript directly in the browser.
