Make community events schedule CMS-editable - #746
Conversation
Replace the hand-maintained Markdown table on /community-events/ with a structured eventsSchedule field rendered through the shared MoreEventsSection component. - Add eventsSchedule (heading + repeatable event list) to the CMS config for the community-events file entry, and name that entry so a preview template can register against it. - Add CommunityEventsPagePreview and register it in cms.js. - Query eventsSchedule in the page template and render MoreEventsSection above the body content, guarded so content without the field still renders. - Give MoreEventsSection a headingTag prop (defaults to h1, so the OpenInfra Days page is unchanged) plus React keys and list roles. - Scope the new styles under .community-events-schedule so they cannot affect the other MoreEventsSection consumer. - Ignore .env.prod.secret. Editors can now add, reorder and remove events in the CMS instead of editing a Markdown table. Event names and dates are unchanged from the table; per-event locations are new.

Render the schedule title as text or sanitize it before using dangerouslySetInnerHTML.
The CMS-controlled title reaches a raw HTML sink. Render it as React text, or apply a strict allowlist sanitizer before insertion.
🧰 Tools
🪛 React Doctor (0.9.12)
[error] 16-16: dangerouslySetInnerHTML is an XSS hole that runs attacker-controlled HTML in your users' browsers.
Render trusted content as React children so attacker-controlled HTML cannot run in users' browsers.

Do not render CMS heading HTML without sanitization.
eventsSchedule.title flows from the CMS to MoreEventsSection, which passes it directly to dangerouslySetInnerHTML. A CMS author can store markup that executes in public-page visitors’ browsers. Render the heading as text, or sanitize it with a strict HTML policy before rendering.

What
Replaces the hand-maintained Markdown table on
/community-events/with a structured, CMS-editableeventsSchedulefield, rendered through the existingMoreEventsSectioncomponent.Preview: the Netlify deploy preview on this PR renders the new section — see
/community-events/.Why
The schedule was a Markdown table, so editors had to hand-edit table syntax to add or reorder an event. It is now a repeatable list in the CMS.
Changes
static/admin/config.yml— addeventsSchedule(heading + event list: name, date, location, optional link). Set the file entry'snametocommunity-eventsso a preview template can register against it, matching the existingopeninfra-days/summit-landing-pageconvention.src/cms/preview-templates/CommunityEventsPagePreview.js— new preview template, registered insrc/cms/cms.js.src/templates/community-events-page.js— queryeventsSchedule, renderMoreEventsSectionabove the body content, guarded onevents.lengthso content without the field still renders.src/components/MoreEventsSection/index.jsx— add aheadingTagprop, plus React keys and list roles.src/style/modules/_community-events.scss— new styles, scoped under.community-events-schedule..gitignore— ignore.env.prod.secret.Compatibility
headingTagdefaults toh1, so the other consumer (src/templates/open-infra-days-page.js) is unchanged. The new SCSS is scoped so it cannot reach that page either. This page passesh2, which makes the schedule a peer of the##body sections instead of the previous###.Verification
Full production
gatsby buildpasses locally (exit 0). The built/community-events/page renders the heading, 12agenda-rowentries and all 12 event names. Checked in Chrome at desktop and at the mobile breakpoint: no horizontal overflow, grid collapses to one column, and the new:focus-visibleoutline works for all 11 event links.Note: local build used Node 16.17.0 while Netlify builds on 14.20.1 per
netlify.toml, so the deploy preview on this PR is the real check.For review
Separately, and not in this PR: OpenInfra Day Nigeria shows August 29, 2026 here and on production, but its linked Meetup page says May 16, 2026.
