Follow the installation guide in the n8n community nodes documentation.
This node was developed and tested with version 0.193.5 of n8n.
If you install this node, n8n will install automatically the next extra npm packages:
- handlebars: required to work with Handlebars templates
The node can solve multiple use cases when creating content like:
- Email generation (HTML or TEXT)
- Static HTML pages
- WordPress posts
- Telegram/Slack messages
The sky is your limit!
Just follow the next samples to create your dynamic content and forget to use SET, FUNCTION, or FUNCTION ITEM nodes.
- You want to send a list of recent news about n8n.
- You want to send the list of the customers created in the last hour in your database.
Supposing that you have a customer list in JSON:
[
{
"email": "miquel@n8nhackers.com",
"name": "Miquel"
},
{
"email": "contact@n8nhackers.com",
"name": "Contact"
}
]You need to use this template:
<ul id="customer_list">
{{#each items}}
<li>{{name}}: {{email}}</li>
{{/each}}
</ul>
And you will get the next output to send by email in HTML format:
<ul id="customer_list">
<li>Miquel: miquel@n8nhackers.com</li>
<li>Contact: contact@n8nhackers.com</li>
</ul>
Property items is always mandatory to iterate over all items.
- You have an invoice with header and lines and you want to send it by email.
If you have one item/invoice with this JSON:
{
"date": "2022-01-12",
"to": "N8n hackers",
"address": "Granollers, Spain",
"total": 133.10,
"lines": [
{
"description": "Create a node to render items in handlebar templates",
"quantity": 1,
"amount": 100,
"vat": 21,
"total": 121
},
{
"description": "Test a node to render items in handlebar templates",
"quantity": 1,
"amount": 10,
"vat": 2.10,
"total": 12.1
}
]
}You need to use this template:
Date: {{date}}
To: {{to}}
Address: {{address}}
Details:
{{#each lines}}
- "{{description}}" x {{quantity}} = {{amount}}€ + {{vat}}€ = {{total}}€
{{/each}}
Total invoice: {{total}}€
And you will get the next output to send by email in TEXT format:
Date: 2022-01-12
To: N8n hackers
Address: Granollers, Spain
Details:
- "Create a node to render items in handlebar templates" x 1 = 100€ + 21€ = 121€
- "Test a node to render items in handlebar templates" x 1 = 10€ + 2.10€ = 12.10€
Total invoice: 133.10€
I recommend using this method if you want to send multiple invoices.
Please, check the official page to review all the existing expressions in Handlebars.
