timoreymann/mealie-webhook-handler repository overview

⁠mealie-webhook-handler

Webhook handler for recipes hosted on a mealie.io instance

⁠Features

• Customizable templates
• Generic output support

⁠Purpose

This small service bridges Mealie⁠ (self-hosted recipe manager) with external systems by:

1. Listening for webhooks triggered by the user in the UI.
2. Rendering recipes using customizable Go templates (e.g., for Chowdown⁠).
3. Pushing output to destinations like GitHub repos (via PR)

Key Use Case: Automate syncing Mealie recipes to a Chowdown-compatible GitHub repo (or other targets) with minimal manual effort.

⁠Want to contribute a new output?

Right now the only supported output is GitHub via PR. If you have any other destinations feel free to either create an issue or contribute directly:

1. Fork this repository
2. Add a new output in outputs/<your name>/main.go (see github_pr for reference)
3. Create a PR

⁠Installation

It's recommended to install it next to your mealie instance using docker-compose.

1. Create webhook-templates/chowdown-template.gotpl

   ---
   layout: recipe
   title: {{ .Recipe.Name }}
   {{- if .HasImage }}
   image: {{ .Recipe.Slug }}.webp
   {{- end }}
   tags: {{- range $index, $tag := .Recipe.Tags }} {{- if $index }},{{ end }} {{ $tag.Name }} {{- end }}
   
   ingredients:
   {{- range $val := .Recipe.RecipeIngredient }}
     - {{ if $val.Quantity }} {{ $val.Quantity }}{{- end -}}{{- if $val.Unit }} {{ or $val.Unit.Abbreviation $val.Unit.Name }}{{- end }} {{ if or $val.Quantity $val.Unit }} {{- end }}{{ $val.Food.Name }}{{- if $val.Note }} {{ $val.Note }}{{- end }}
   {{- end }}
   
   directions:
   {{- range $val := .Recipe.RecipeInstructions }}
     - {{ $val.Text }}
   {{- end }}
   ---
   
   {{ .Recipe.Description }}
   

   Copy
2. Create a webhook-config.toml

   # chowdown is a sample GitHub webhook to sync recipes to chowdown github repos
   [webhook.chowdown_github_sync]
   template_path = "/etc/mealie-webhook-handler/templates/chowdown-template.gotpl"
   output = "github_pr"
    
   [webhook.chowdown_github_sync.output_options]
   title = "chore: Sync recipe {{ .Recipe.Name }} from mealie"
   body = """
   Update recipe {{ .Recipe.Name }}
   """
   slug = "your-user/recipes"
   source_branch = "sync/recipe/{{ .Recipe.Slug }}"
   target_branch = "gh-pages"
   recipe_path = "_recipes/{{ .Recipe.Slug }}.md"
   image_path = "images/{{ .Recipe.Slug }}.webp"
   commit_message = "chore: Sync {{ .Recipe.Name }} from mealie"
    
   [mealie]
   api_url = "http://mealie:9000/api"
   

   Copy
3. Configure the webhook handler next to mealie

   services:
     mealie:
     # mealie configuration
     mealie-webhook-handler:
       image: timoreymann/mealie-webhook-handler
       restart: always
       environment:
         GITHUB_TOKEN: <personal access token>
       command:
         - mealie-webhook-handler
         - --config-file
         - /etc/mealie-webhook-handler/config.toml
       volumes:
         - ./webhook-config.toml:/etc/mealie-webhook-handler/config.toml
         - ./webhook-templates:/etc/mealie-webhook-handler/templates
   

   Copy

2. Go to Settings > Data Management
3. Select Recipe Actions

5. Fill out the form
   • Title: Sync to Chowdown
   • URL: http://mealie-webhook-handler:2025/webhook/chowdown_github_sync⁠

⁠Creating the template

Creating templates can sometimes be tricky, to make it easier there is the playground⁠ that can be used.

Simply put your template in, pick one of the predefined webhook payloads or paste a custom one and get immediate feedback.
