feat(code): add channel share link interstitial for posthog code by k11kirky · Pull Request #68479 · PostHog/posthog

k11kirky · 2026-07-05T22:32:04Z

Problem

PostHog Code is adding "Copy link" sharing for Channels-space channels and the threads inside them (PostHog/code#3157). Like canvas share links, these are https links so they work for recipients without the desktop app — but that requires a web interstitial on Cloud to bridge into the posthog-code:// scheme, and only /code/canvas/... had one.

Changes

New CodeChannelLink scene (unauthenticated, app-raw, same folder as CodeCanvasLink) serving /code/channel/:channelId and /code/channel/:channelId/tasks/:taskId. On mount it fires posthog-code(-dev)://channel/<channelId>[/tasks/<taskId>] into the desktop app, with a manual "Open in PostHog Code" button and a download link as fallback.
Extracted the DESKTOP_SCHEME constant into desktopScheme.ts, now shared by both interstitials instead of duplicated.

How did you test this code?

Structural mirror of the existing CodeCanvasLink scene with the same registry wiring (sceneTypes, sceneConfigurations, routes, appScenes, urls).
Agent limitations: this session had a sparse checkout without node_modules, so typescript:check, format, and ci:preflight were not run locally — please rely on CI for those. No automated tests added: the sibling canvas interstitial has none, and the scene is a static redirect page with no logic beyond URL construction.

N/A — the deep-link format is documented in the PostHog/code repo (docs/DEEP-LINKS.md) alongside the handler.

🤖 Agent context

Autonomy: Human-driven (agent-assisted)

Authored with PostHog Code (Claude) from a project-bluebird channel task requesting shareable channel/thread links. The agent followed the established canvas share-link precedent: desktop-side scheme handler and copy affordances live in PostHog/code#3157; this PR is the Cloud bridge. A generic path-forwarding interstitial was considered and rejected in favor of mirroring the existing per-surface scene, which keeps route params validated per link type. A /simplify review pass extracted the previously duplicated DESKTOP_SCHEME constant.

Created with PostHog Code

Adds an unauthenticated bridge scene for /code/channel/<channelId> and /code/channel/<channelId>/tasks/<taskId> share links, mirroring the existing CodeCanvasLink interstitial: on mount it fires the posthog-code(-dev):// scheme into the desktop app, with a manual open button and download link as fallback. Extracts the shared DESKTOP_SCHEME constant used by both interstitials. Generated-By: PostHog Code Task-Id: b60d15a7-ac68-4869-bb42-55e66943823a

Hey @k11kirky! 👋

It looks like your git author email on this PR isn't your @posthog.com address (k11kirky@gmail.com). Since you're on the PostHog team, it's worth pointing your local git author email at your @posthog.com address. Why it matters:

Consistent work identity in git history — internal tooling that attributes commits to team members keys off your @posthog.com address.
Keeps team contributions easy to tell apart from external community ones when scanning history.

You can fix it for this repo with:

git config user.email "you@posthog.com"

Or set it globally with git config --global user.email "you@posthog.com". No need to redo this PR — just a nudge for next time. 🙂
