Templates

The plugin uses the Postmark template system for emails. For attachments the plugin relies on the pdfkit library.
In your JSON templates you can use several types (and variables):

image for (local) images
text for simple words, (long) sentences, paragraphs and links
moveDown for moving the cursor down one line
hr for a horizontal line
tableRow for a table(-like) row
itemLoop for looping over items in an order
itemLoopEnd for ending the item loop

Example:

[
  {
    "type": "image",
    "image": "image.png",
    "x": 100,
    "y": 100,
    "fit": [200, 50]
  },
  {
    "type": "text",
    "text": "This is a text",
    "size": 20
  },
  {
    "type": "moveDown",
    "lines": 2
  },
  {
    "type": "hr"
  },
  {
    "type": "moveDown",
    "lines": 2
  },
  {
    "type": "text",
    "text": "Another text"
  }
]

image

Images are stored in /src/images/ and can be used in the template like this:

{
    "type": "image",
    "image": "image.png",
    "x": 100,
    "y": 100,
    "fit": [200, 50]
}

fit has multiple options, see here for more info.

Optional:

align horizontally align the image, the possible values are left, center, or right
valign vertically align the image, the possible values are top, center, or bottom

text

Text can be used for words, sentences, paragraphs and links.

{
    "type": "text",
    "text": "This is a text"
}

If you use moveDown correct you won't need to use x and y for the text.

Optional:

These options can be used to style the text or to position it.

x the x position of the text
y the y position of the text
font the font of the text
size the font size of the text
color the color of the text (Hex codes #ff0000)
width the width of the text
align the alignment of the text, the possible values are left, center, right, or justify.

For more styling options, see here for more info.

moveDown

This is used to move the cursor down one or more line(s).

{
    "type": "moveDown",
    "lines": 1
}

hr

This is used to draw a horizontal line.

{
    "type": "hr"
}

Optional:

color the color of the line (Hex codes #ff0000)
width the width of the line if you don't want it to be the full width of the page
height the height of the line element, including padding
y the y position of the line if you can not rely on the cursor (affected by moveDown)

tableRow

This is used to draw a table row.

{
    "type": "tableRow",
    "columns": [
        {
            "text": "Column 1",
            "width": 200
        },
        {
            "text": "Column 2",
            "width": 150
        }
    ]
}

Optional:

You can use the same options as for text to style the text in the table row. If you want a special column styled, you can add the options to the column object.

itemLoop

This is used to start the loop of items in an order.
To access item variables, use the item object, for example {{ item.title }}.

{
    "type": "itemLoop"
}

itemLoopEnd

This is used to end the loop of items in an order.

{
    "type": "itemLoopEnd"
}

Variables

In the template you can use variables. These are replaced by the plugin with the correct value.
To use a variable, use the following syntax: {{ variable_name }}, for example {{ order.customer.first_name }}.
Order item variables are available inside the itemLoop and itemLoopEnd elements, for example {{ item.title }}.
If you want to include (simple) if statements, use the following syntax: {{ if variable_name }}...{{ endif }}, or as a negative {{ if not variable_name }}...{{ endif }}.
Possible variables depend on your notification system. You can use the options object and every template has his own data object.
Depending on the plugin you use, (almost) every plugin that supports attachments based on medusa-plugin-sendgrid has the same variable order after the options variable which holds all the plugin variables.
More information on the possible values that order can have can be found here.

Variable functions

At the moment the only variable you can use functions with is dates and currency.

Dates are formatted using the toLocaleDateString function and can be used like this: {{ order.placed_at | date('en-US',{'year': 'numeric', 'month': 'long', 'day': 'numeric'}) }}.
Currency is formatted using the new Intl.NumberFormat() function and can be used like this: {{ order.total_price | currency('en-US') }}.
Country can be formatted from ISO to the full country name and can be used like this: {{ order.shipping_address.country_code | country }}.
Please make sure that the options are wrapped in single quotes.

Localisation

Want separate templates for different languages?
Alter medusa-config.js plugin options:

// medusa config including the postmark plugin
events: {
    order: {
        placed: { nl: 1234, en: 1235 },
// rest of the events...

The api key and templates are pulled from env variables.

POSTMARK_SERVER_API=""
POSTMARK_FROM=""
POSTMARK_ORDER_PLACED=1234

The POSTMARK_FROM email address must be a verified sender in your Postmark account.

Default templates

We've created a few default templates (thanks to pdfkit invoice example) which can be altered to your needs: header.json
