Mendoza decoder in TypeScript.

Installation

``bash
npm install mendoza
`

or

`bash
pnpm install mendoza
`

or

`bash
yarn add mendoza
`

Usage

Basic example:

`typescript
import {applyPatch} from "mendoza"

let left = {…};
let patch = […];
let right = applyPatch(left, patch);
`

Incremental patcher:

`typescript
import {incremental} from "mendoza"

const {Value, rebaseValue, wrap, unwrap, getType, applyPatch} = incremental

// Create an empty initial version:
const ROOT = wrap(null, null);

// Input of patches:
let patches = […];

// origin can be whatever you want to identify where a change comes from:
let origin = 0;

// Reference to the latest version:
let value = ROOT;

// Rebasing is for maintaing history across deleted versions:
let rebaseTarget;

for (let patch of patches) {
// Apply the patch:
let newValue = applyPatch(value, patch, origin);

// Rebase if needed:
if (rebaseTarget) {
newValue = rebaseValue(rebaseTarget, newValue);
}

// If the document was deleted, store the previous version so we can rebase:
if (getType(newValue) === "null") {
rebaseTarget = value;
} else {
rebaseTarget = null;
}

value = newValue;
origin++;
}

// Return the final full object:
console.log(unwrap(value));
