Purpose

The goal of FortuneSheet is to make a feature-rich, easy-to-configure online spreadsheet that you can use out-of-the-box.

This project is originated from Luckysheet and has inherited many code from it. Lots of efforts have done to translate the whole project to typescript (still in progress), and solved problems in the design of the original project.

We aim to make FortuneSheet powerful yet easy to maintain.

Documentation

Get started (react)

Download and install the library

<details open> <summary>Using npm</summary>
npm install @fortune-sheet/react
</details> <details> <summary>Using pnpm</summary>
pnpm install @fortune-sheet/react
</details> <details> <summary>Using yarn</summary>
yarn add @fortune-sheet/react
</details>

Create an HTML placeholder

<style>
  html, body, #root {
    width: 100%;
    height: 100%;
  }
</style>
<div id="root"></div>

NOTE: width and height doesn't have to be 100%, but should at least have a value. If set to auto, table area may not show.

Render the sheet

import React from 'react';
import ReactDOM from 'react-dom';
import { Workbook } from "@fortune-sheet/react";
import "@fortune-sheet/react/dist/index.css"

ReactDOM.render(
  <Workbook data={[{ name: "Sheet1" }]} />,
  document.getElementById('root')
);

Backend storage and collabration

Each time a user operates on the sheet, an array of Op will be emiited through onOp callback. An op describes how to modify the current data to reach the new data after the user's operation. For example, here is an op when user sets the cell font to be bold on cell A2.

[
    {
        "op": "replace",
        "index": "0",
        "path": ["data", 1, 0, "bl"],
        "value": 1
    }
]

The op is useful for database modification and syncing state in online collabration.

A working example with Express (backend server) and MongoDB (data persistence) is avaiable in backend-demo folder.

Run it with node index.js and visit Collabration example (initialize data by visiting http://localhost:8081/init)

For detailed doc about Op, refer to fortune-sheet-doc

Migrating data from Luckysheet

The overall data structure of FortuneSheet is the same as Luckysheet, with some naming differences:

  1. sheet.index -> sheet.id
  2. sheet.calcChain[].id -> sheet.calcChain[].id
