Micropub to GitHub
An endpoint that accepts Micropub requests, formats them into Jekyll posts before pushing them to a configured GitHub repository. This enables updating a Jekyll blog through a Micropub client.
Early alpha
Supported:
- Creation of posts
- Uploading of media
- Replacing an existing post with a new version
Unsupported:
- Partial update
- Deletes
Requirements
Requires at least Node.js 14.0.0.
This project contains a https://yarnpkg.com/ lock file which is a faster and more secure alternative to the npm client.
Installation
Install as a normal Node.js application. Add the required configuration values via environment variables or similar mechanism. Or deploy to Heroku:
Endpoint discovery
Once deployed, your Micropub endpoint can be found at /micropub/main e.g. https://example.com/micropub/main.
If you specified more than one site using the MICROPUB_SITES_JSON variable, then each endpoint will be available under the name of its respective key, i.e. /micropub/key-name.
To enable automatic discovery for your Micropub endpoint and token endpoint, you will need to add the following values to your site's <head>:
<link rel="micropub" href="https://example.com/micropub/main">
<link rel="token_endpoint" href="https://tokens.indieauth.com/token">

All values explicitly set in the Micropub request are available, but some defaults and derived values may not be available, depending on the option configured.
Please open an issue and let me know what conditions you would like to set up.
Modules used
-
micropub-express – an Express Micropub endpoint that accepts and verifies Micropub requests and calls a callback with a parsed

format-microformat – a module that takes a
micropubDocumentas its input, and converts this data into a standard that can be published elsewhere. Currently supports the Jekyll format. -
