Publishing Flow (Full Example)

The recommended flow to create and publish a note:

// 1. Sign in
await client.signIn({
  login: "your_email@example.com",
  password: "your_password",
  g_recaptcha_response: "",
  redirect_path: "/",
});

// 2. Create a draft
const created = await client.createNote({
  title: "My Article",
  body: "",
});

// 3. Save draft with content
await client.saveDraft({
  id: created.id.toString(),
  title: "My Article",
  body: "<p>Article content here</p>",
  isTempSaved: false,
  index: false,
});

// 4. Publish
await client.editNote({
  id: created.id.toString(),
  title: "My Article",
  body: "<p>Article content here</p>",
});

Table of Contents (目次)

To add a table of contents that auto-generates links from headings, use the <table-of-contents> tag and set index: true in both saveDraft and editNote.

Supported HTML Tags

TagDescriptionAppears in TOC?
<table-of-contents>Table of contents block
<h2>Large headingYes
<h3>Small headingNo
<p>ParagraphNo
<ul>, <ol>, <li>ListsNo
<blockquote>QuoteNo
<pre><code>Code blockNo
<figure>, <img>ImageNo
<hr>Horizontal ruleNo
<strong>, <em>, <a>, <br>Inline formattingNo

Note: <table> HTML tags are not supported and will be stripped by note.com.

Building the Body HTML

Every element should have a unique name and id attribute (UUID v4):

import crypto from "crypto";
const uuid = () => crypto.randomUUID();

const body = [
  // Table of contents (place before headings)
  `<table-of-contents name="${uuid()}" id="${uuid()}"><br></table-of-contents>`,
  // Headings & content
  `<h2 name="${uuid()}" id="${uuid()}">Introduction</h2>`,
  `<p name="${uuid()}" id="${uuid()}">First paragraph.</p>`,
  `<h2 name="${uuid()}" id="${uuid()}">Main Topic</h2>`,
  `<p name="${uuid()}" id="${uuid()}">Second paragraph.</p>`,
  `<h3 name="${uuid()}" id="${uuid()}">Sub Topic</h3>`,
  `<p name="${uuid()}" id="${uuid()}">Details here.</p>`,
  `<h2 name="${uuid()}" id="${uuid()}">Conclusion</h2>`,
  `<p name="${uuid()}" id="${uuid()}">Summary.</p>`,
].join("");

Full Example with TOC

// 1. Create draft
const created = await client.createNote({ title: "My Article", body: "" });

// 2. Save draft with index: true
await client.saveDraft({
  id: created.id.toString(),
  title: "My Article",
  body: body, // HTML with <table-of-contents> and <h2> tags
  isTempSaved: false,
  index: true, // Required for TOC
});

// 3. Publish with index: true
await client.editNote({
  id: created.id.toString(),
  title: "My Article",
  body: body,
  index: true, // Required for TOC
});
