agentic-doc

agentic-doc is an open-source HTML template renderer for Node.js developers and agents that writes local HTML or Cloudflare Browser Rendering PDFs.

Install

npm install agentic-doc

Requires Node.js 18 or later. Includes TypeScript declarations and two runtime dependencies.

Render your first document

cat > template.html <<'HTML'
<h1>Hello {{name}}</h1>
HTML
printf '{"name":"Ada"}' > slots.json
npx agentic-doc render --template template.html --slots slots.json --output result.html
npx agentic-doc render --template template.html --slots slots.json --output result.html --live
cat result.html

The first command previews JSON with dryRun: true and writes nothing. The second writes local HTML. The final command prints <h1>Hello Ada</h1>.

Features and coverage

• Template slots: Replace {{name}} placeholders with string values; missing slots raise errors.
• Preview: Inspect filled HTML before file writes or vendor calls.
• HTML output: Write a local file without credentials.
• PDF output: Send filled HTML to Cloudflare Browser Rendering.

| Output | Provider | Status | | --- | --- | --- | | HTML | Local filesystem | Implemented; local tests | | PDF | Cloudflare Browser Rendering | Implemented; mocked HTTP test; live credentials unverified |

For PDFs, export CLOUDFLARE_API_TOKEN and CLOUDFLARE_ACCOUNT_ID. The package does not load .env files; load them before running the command.

npx agentic-doc render --template template.html --slots slots.json --output result.pdf --format pdf --live

Success returns JSON with vendor: "cloudflare" and writes result.pdf.

Library and agent tools

import { renderDocument } from "agentic-doc";

const result = await renderDocument({
  template: "template.html",
  slots: { name: "Ada" },
  output: "result.html",
});
console.log(result.html); // <h1>Hello Ada</h1>

Set dryRun: false to write files. PDF requests also require live: true. The CLI supports render, --help, and --version. Run npx --package agentic-doc agentic-doc-mcp for the Model Context Protocol (MCP) stdio server. Its single tool is render_document, with the same request fields and dry-run default.

Limits and status

Slot values are inserted verbatim; escape untrusted HTML yourself. The PDF request has no built-in retry or explicit timeout. The Worker source contains text-summary scaffolding, not a document-rendering service. Version 0.1.1 has an API that may change. No managed rendering service is included.
