One-click Post to GitHub (GitHub App) - #14
Merged
Conversation
A Cloudflare Pages Function authenticates as our installed GitHub App (private key in env), then creates a branch, commits the post folder, and opens a PR directly on the repo — always off the latest main. The client just assembles the files (index.mdx, sidecar, images, cover) and POSTs them. Writers click one button; the ZIP download stays as the fallback. Gated by SITE.githubPostEnabled + an origin check on the endpoint.

What
Adds a Post to GitHub button in /write. One click → a PR with the full post folder is opened on this repo. No user login, no forks. The existing Download post flow is untouched (now shown as a secondary button).
How
src/write/publish/github.ts) assembles the post files (index.mdx,.write-source.json, images, cover, component files) and POSTs them to/api/create-pr.functions/api/create-pr.ts) authenticates as our installed GitHub App (private key from env → JWT → installation token), then creates a branch off the latestmain, commits the files, and opens the PR. The App token never leaves the server.SITE.githubPostEnabled(button hidden until true) + anOrigincheck on the endpoint.Required setup (not in code)
