@rimbu/deep

Offers tools to use handle plain JS objects as immutable objects. The Patch object allows convenient immutable modification of simple objects. The Match object allows easy matching on plain objects. The Path object allows easy querying of nested values. The Immutable type makes it easy to create plain objects that that have compile-time protection against mutation. The Tuple type is a utility to have similar functionality as as const but less strict.

For complete documentation please visit the Immutable Objects overview in the Rimbu Docs.

Or Try Out Rimbu in CodeSandBox.

Installation

All types are exported through @rimbu/core. It is recommended to use that package.

To install this package only:

Yarn/NPM

yarn add @rimbu/deep

npm i @rimbu/deep

Deno

Create a file called rimbu.ts and add the following:

export * from 'https://deno.land/x/rimbu/deep/mod.ts';

Or using a pinned version (x.y.z):

export * from 'https://deno.land/x/rimbu/deep@x.y.z/mod.ts';

Then import what you need from rimbu.ts:

import { patch } from './rimbu.ts';

Because Rimbu uses complex types, it's recommended to use the --no-check flag (your editor should already have checked your code) and to specify a tsconfig.json file with the settings described below.

Running your script then becomes:

deno run --no-check --config tsconfig.json <your-script>.ts

Usage

import { patch } from '@rimbu/deep';

console.log(
  patch({
    a: 'a',
    b: { c: 1, d: true },
  })({
    a: 'q',
    b: { c: (v) => v + 1 },
  })
);
// => { a: 'q', b: { c: 2, d: true }}
