About this fork (CSG)

This repository is a fork of the original usewaypoint/email-builder-js, which is no longer maintained. This fork is maintained by CSG. Published npm packages use the @csg-org scope — install with npm install @csg-org/email-builder (not @usewaypoint/email-builder).

Maintainers: Updating and publishing to npm

This fork publishes packages under the @csg-org scope. Use the scripts in bin/ to bump versions and publish to npm.

Prerequisites

  • You must be logged in to npm (npm login) and have publish access to the @csg-org scope.
  • All packages under packages/ should be in a consistent state (clean build, tests passing).

1. Version management: bin/version.sh

The monorepo keeps a single version across all package.json files under packages/. Use version.sh to read or set that version. The root package.json version is pinned at 0.0.0 — it is not published to npm and is intentionally not updated by version.sh.

Command Description
./bin/version.sh get Print the current version (from packages/email-builder). Fails if any package version disagrees.
./bin/version.sh audit Verify that every packages/*/package.json has the same version.
./bin/version.sh upgrade <new-version> Set version to <new-version> in every packages/*/package.json, and set all @csg-org/* dependency versions in packages/email-builder/package.json to ^<new-version>.

Example — bump to a new patch version:

./bin/version.sh get          # e.g. 0.0.11
./bin/version.sh upgrade 0.0.12
./bin/version.sh audit        # optional: confirm all versions match

2. Publish to npm: bin/ship-it.sh

ship-it.sh builds and publishes the publishable packages to npm in dependency order:

  1. Block packages — all packages/block-* packages.
  2. document-corepackages/document-core (same steps).
  3. email-builderpackages/email-builder (same steps). This package depends on all of the above.

Example — full release:

./bin/version.sh upgrade 0.0.12
./bin/ship-it.sh

The script pauses after publishing the subpackages. Wait until all @csg-org packages show the new version on npm, then press Enter to publish @csg-org/email-builder.

You can preview what will happen without actually publishing by passing --dry-run:

./bin/ship-it.sh --dry-run

Notes:

  • packages/editor-sample is not published; it is only used for local development.
  • package-lock.json files inside each package may drift after version.sh upgrade. This is expected — ship-it.sh runs npm install in each package before publishing, which reconciles them.

Everything below is the original README. Code examples use the old @usewaypoint/email-builder import; for this fork use @csg-org/email-builder instead.


Introduction

EmailBuilder.js is a free and open-source email template builder for developers. Build emails faster than ever with clean JSON or HTML output that render well across clients and devices.

Use our playground or learn more about how to get started using EmailBuilder.js.

Build simple welcome emails to complex reports

Use a no-code builder that is flexible enough to create a wide variety of template designs – from simple welcome emails to complex reports.

Sample templates available in the playground:


Why?

It's finally time to stop using 90's style HTML and CSS to build product emails. EmailBuilder.js takes inspiration from editor.js and email component libraries and puts them into an easy to use no-code builder to that allow the entire team to build emails.

Since the builder is completely free and open source, teams can self-host the builder and extend as needed.


Built-in blocks

Each block is it's own npm package that can be included in the builder. These are the ones that are built-in:


Email client support

All blocks are tested and supported by modern email clients (on both desktop and mobile) including: Gmail, Apple Mail, Outlook, Yahoo! Mail, HEY and Superhuman.

Email builder output

The email builder can output to a clean JSON or raw HTML. You can see this from the playground by simply clicking on the HTML or JSON tabs in the builder.

Using EmailBuilder.js

Install the package in your project:

npm install --save @usewaypoint/email-builder

Given an EmailBuilder.js configuration (the JSON output of the builder):

import { TReaderDocument } from '@usewaypoint/email-builder';

const CONFIGURATION: TReaderDocument = {
  root: {
    type: 'EmailLayout',
    data: {
      backdropColor: '#F8F8F8',
      canvasColor: '#FFFFFF',
      textColor: '#242424',
      fontFamily: 'MODERN_SANS',
      childrenIds: ['block-1709578146127'],
    },
  },
  'block-1709578146127': {
    type: 'Text',
    data: {
      style: {
        fontWeight: 'normal',
        padding: {
          top: 16,
          bottom: 16,
          right: 24,
          left: 24,
        },
      },
      props: {
        text: 'Hello world',
      },
    },
  },
};

You can render the EmailBuilder.js configuration to an HTML email string:

import { renderToStaticMarkup } from '@usewaypoint/email-builder';

const string = renderToStaticMarkup(CONFIGURATION, { rootBlockId: 'root' });

Or you can render the EmailBuilder.js configuration by using the <Reader /> React component:

import { Reader } from '@usewaypoint/email-builder';

<Reader document={CONFIGURATION} rootBlockId="root" />;

Sending emails

In most cases, you'll want to take the EmailBuilder.js configuration, render it to HTML, and then send it as an email. Here are a couple of examples on how you can do this using the same configuration from the examples above.


Sending through nodemailer

import { renderToStaticMarkup } from '@usewaypoint/email-builder';
import nodemailer from "nodemailer";

// Replace this with your transport configuration
const transportConfig = {}
const transporter = nodemailer.createTransport(transportConfig);

// Replace this with the JSON for your Reader document
const CONFIGURATION: TReaderDocument = {}

await transporter.sendMail({
  from: 'no-reply@example.com'
  to: 'friend@example.com',
  subject: 'Hello',
  html: renderToStaticMarkup(CONFIGURATION, { rootBlockId: 'root' }),
});

Sending through an email API

We'll use Waypoint for this example, however, you can use any email API like Amazon SES, SendGrid, or MailGun.

import axios from 'axios';

import { renderToStaticMarkup } from '@usewaypoint/email-builder';

// Replace this with the JSON for your Reader document
const CONFIGURATION: TReaderDocument = {}

await axios({
  method: 'post',
  url: 'https://live.waypointapi.com/v1/email_messages',
  headers: {
    'Content-Type': 'application/json',
  },
  auth: {
    username: API_KEY_USERNAME,
    password: API_KEY_PASSWORD,
  },

  data: {
    from: 'no-reply@example.com'
    to: 'friend@example.com',
    subject: 'Hello',
    bodyHtml: renderToStaticMarkup(CONFIGURATION, { rootBlockId: 'root' }),
  },
});

Self hosting the Editor

Fork this repository and use packages/editor-sample as an example for self-hosting.

Quick start:

  1. Fork this repository.
  2. Open up directory in terminal.
  3. Go to the editor-sample package: cd packages/editor-sample
  4. Install packages: npm install
