MJML Conversion Service (self-hosted)

[rallisf1]

I didn't predict our designer wouldn't like the visual editor, plus Canva cannot export to MJML and Notifuse cannot import HTML.

So I vibe coded this: https://github.com/rallisf1/mjml-converter

I am using it with a n8n form where the designer drops the zip downloaded from Canva, selects (to update) or adds (to create) the template metadata (e.g. category, subject, etc.) and the template is pushed to Notifuse via the API.

I'll share the n8n workflow later as it still needs some tuning.

It required quite a few fixes to get it right, but it definitely works.

You must replace anything in ALL_CAPS with your actual domain/credentials.

Assumptions

1. You hardcode your workspaces into the n8n workflow (sadly; there's no API endpoint to fetch the Notifuse workspaces)
2. You use a single S3 bucket for all your workspaces (it requires a lot more work in n8n to use different bucket per workspace, but it's doable)
3. You organize your media files in a /WORKSPACE_NAME/FILENAME manner
4. You are fine with manually deleting unused media files
