Project History

Excel-Builder-Vanilla is a fork of the popular excel-builder.js project (thanks to @stephenliberty for this great library). The main goal of creating this fork was to modernize the project by removing old dependencies that are no longer necessary and also replace JSZip by fflate which provides an ESM build and is indirectly giving us better Tree Shaking. The other goal was also to provide an ESM build to eventually get away from CommonJS (CJS bundle is still offered but we strongly suggest that you migrate to the ESM approach)

The modernization steps:

• migrate to TypeScript (which is giving us TS Types d.ts)
• drop Q dependency (we now simply use native Promise)
• drop Lodash dependency (we now use native JS code)
• replace JSZip dependency with fflate which has an ESM build and offers better performance.
• bump version to v3.0.0 as a major release (the original project version was in the 2.x range.)
  • note that the changelog did not exists prior to v3.0.0

The project now requires only 1 dependency which is fflate.

Summary

This modernization is providing a huge decrease in the final build size, with only 1 dependency, and also offers better performance 🚀

Installation

npm install excel-builder-vanilla

The project offers 3 different build types, choose the best one depending on your use case

1. ESM: to import from (preferred)
2. CJS: CommonJS to support old NodeJS require() - will probably be dropped in the future
3. IIFE: standalone script which provides ExcelBuilder on the window object

// ESM (preferred) - npm install
import { createWorksheet } from 'excel-builder-vanilla';

// CJS - npm install
const { createWorksheet } = require('excel-builder-vanilla');

// IIFE - CDN
<script src="https://cdn.jsdelivr.net/npm/excel-builder-vanilla@3.0.1/dist/excel-builder.iife.js"></script>
<script>
  const worksheet = ExcelBuilder.createWorksheet(); // or window.ExcelBuilder.createWorksheet();
</script>

CSP (Content Security Policy)

Please note that since we use fflate (which creates and compresses the Excel file before sending it to the browser), you might get some CSP errors because of its use of Web Workers. For that reason, you might need to adjust your CSP rules by adding worker-src 'self' blob:;

<meta http-equiv="Content-Security-Policy"
  content="default-src 'self';
   // other rules...
  worker-src 'self' blob:;" />

Used by

This fork was created mostly to support Tree Shaking (ESM), to get away from CJS, to provide TS Types and finally to update all project dependencies. It is used by a few other Open Source libraries that I also maintain and require Excel export:

• Angular-Slickgrid
• Aurelia-Slickgrid
• Slickgrid-React
• Slickgrid-Universal

Pull Request Contribution

Before submitting a PR (pull request), please make sure that you followed these steps for a better chance of a successfull PR:

1. make sure that you have already executed pnpm install
2. run the Biome lint npm script (or simply use step 4)
   • pnpm run biome:lint:write
3. run the Biome code formatting npm script (or simply use step 4)
   • pnpm run biome:format:write
4. run a full Build (this will also run Biome lint/format, so you could skip step 2)
   • pnpm run build
