Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@nowline/export-xlsx

Five-sheet Excel workbook export for Nowline roadmaps. Built on exceljs; tuned for determinism and filter/sort-friendly column shapes.

License: Apache 2.0 Part of: lolay/nowline monorepo Spec: specs/handoffs/m2c.md § 7 + specs/rendering.md § XLSX Export

Install

pnpm add @nowline/export-xlsx @nowline/export-core

Usage

import { exportXlsx } from '@nowline/export-xlsx';

const xlsx = await exportXlsx(inputs, {
    author: 'Roadmap Bot',
    generated: new Date('2026-01-01T00:00:00Z'),
});

// `xlsx` is a Uint8Array — a zip-formatted Office Open XML workbook.

Sheet layout

| Sheet | Columns | Notes | |--------------------|---------|-------| | Roadmap | Title, Author, Generated, Source path | Workbook overview. | | Items | id, title, swimlane, group, parallel, status, owner, after, before, duration (working days), duration (text), labels, description | One row per item. The numeric duration column is in working days for SUM and filters; the text column preserves the original DSL literal (2w, 1m, etc.). | | Milestones | id, title, after / before, date | One row per milestone. | | Anchors | id, title, date | One row per anchor. | | People & Teams | id, name, type (person|team) | Ownership references. |

Conditional formatting on Items.status highlights done, in-progress, blocked, and any custom statuses defined in the AST.

Determinism

  • workbook.created = inputs.today (UTC midnight) — never new Date() in the default code path.
  • Sheet 1's "Generated" cell takes the same today.
  • Style ids and column orders are explicit so ExcelJS's id allocator emits the same numbers across runs.
  • ExcelJS version is pinned in package.json. If the upstream library ever introduces zip-level non-determinism, the package's writer re-emits content streams in deterministic order before zipping (m2c Resolution 8).
  • Hash tests in test/export-xlsx.test.ts confirm byte stability.

Options

| Option | Default | Notes | |--------------|------------------------|-------| | author | 'Nowline' | Workbook Author, also the Roadmap-sheet "Author" cell. | | generated | inputs.today | Workbook created, also the Roadmap-sheet "Generated" cell. |
