Esm-mailwind NPM

Mailwind

Use Tailwind CSS to design HTML emails.

This project is based of 'mailwind' developped by @soheilpro. However, I had a few problems when using mailwind. So I made this esm-friendly version to satisfy my needs.

Difference with solheilpro/mailwind

Features	esm-mailwind	mailwind
Parse tailwind html	✔️	✔️
Parse tailwind config	✔️	✔️
Convert 'rem' to 'px'	✔️	❌
Resolves CSS variables	✔️	❌
ESM-friendly	✔️	❌

Install

npm install esm-mailwind --save-dev

or if you want to install globally:

npm install esm-mailwind -g

Usage

Design your HTML email using the Tailwind utility classes like you normally would for the web.

Then run the following command to generate the corresponding CSS file:

mailwind --input-html email.html --output-css style.css

Or run this command to generate an inlined HTML file:

mailwind --input-html email.html --output-html email-inlined.html

If you want to specify your own base pixels per 1rem:

mailwind --input-html email.html --output-html email-inlined.html --base-px 16

Options

--input-css

The path to your base CSS file. Use this if you need to write custom CSS. Defaults to style.css.

--input-html

The path to your HTML email file.

--output-css (optional)

The path to the CSS file that will be generated.

--output-html

The path to the inlined HTML file that will be generated.

--tailwind-config (optional)

The path to your custom Tailwind configuration file. Defaults to tailwind.config.js.

--base-px (optional)

The base number of pixels per 1rem; default = 16.

Note

In the provided default config file, all the units are changed to pixel which is probably what you want for HTML emails.

Example

Given an email.html file with this content:

<html>
  <body>
    <p class="font-bold text-lg">Welcome</p>
  </body>
</html>

running this command:

mailwind \
  --input-html email.html \
  --output-css style.css \
  --output-html email-inlined.html

will generate the following CSS and inlined HTML files:

.text-lg {
  font-size: 18px
}

.font-bold {
  font-weight: 700
}

<html>
  <body>
    <p class="font-bold text-lg" style="font-size: 18px; font-weight: 700;">Welcome</p>
  </body>
</html>
