feat(blog-publish): route LinkedIn cross-post via micro.blog Micropub#45
Merged
Conversation
Replace the direct LinkedIn UGC Posts API path with a Micropub POST to micro.blog. The note lands on doughatcher.com/ (microblog timeline) and micro.blog syndicates it to LinkedIn (and any other configured cross-post destinations). Why: LinkedIn access tokens expire every 60 days and require manual OAuth refresh. Micro.blog app tokens don't expire, and the user already has LinkedIn configured as a cross-post destination there. Changes: - new apps/editorial-loop/lib/microblog-poster.js (Micropub client) - apps/editorial-loop/publish.js now imports microblog-poster - delete apps/editorial-loop/lib/linkedin-poster.js (unused) - blog-publish.yml: env now MICROBLOG_APP_TOKEN + optional MICROBLOG_DESTINATION_UID, gated on vars.MICROBLOG_CROSSPOST_ENABLED - pre-generated linkedin_copy frontmatter is still used verbatim — field name preserved since LinkedIn is still the syndication target Required GitHub config to enable: - secret MICROBLOG_APP_TOKEN (from https://micro.blog/account/apps) - var MICROBLOG_CROSSPOST_ENABLED=true - var MICROBLOG_DESTINATION_UID (optional; only if token sees multiple sites)

LinkedIn access tokens expire every 60 days and need OAuth refresh. Micro.blog app tokens don't expire, and LinkedIn is already configured as a cross-post destination on the micro.blog account — let micro.blog do the syndication.
