Fix dashboard initialization failures due to missing dependencies by Copilot · Pull Request #88 · Hack23/riksdagsmonitor

Copilot · 2026-02-11T12:59:44Z

Three dashboards (committees, coalition, election-cycle) failed to initialize with ReferenceError: Papa is not defined and Error: This method is not implemented: Check that a complete date adapter is provided.

Changes

Added missing dependencies (69KB, locally hosted):

papaparse.5.5.3.min.js (19KB) - CSV parsing for data ingestion
chartjs-adapter-date-fns.3.0.0.bundle.min.js (50KB) - Chart.js time-series support

Updated HTML (15 files):

index.html + 13 language variants with library script tags
Load order: D3 → Chart.js → plugins → adapters → Papa Parse → dashboards

Updated documentation:

SECURITY_ARCHITECTURE.md - External dependencies list and risk table
ARCHITECTURE.md - Technology stack and dependency diagram

Library loading order

<script src="js/lib/d3.7.9.0.min.js"></script>
<script src="js/lib/chart.umd.4.4.1.js"></script>
<script src="js/lib/chartjs-plugin-annotation.3.0.1.min.js"></script>
<script src="js/lib/chartjs-adapter-date-fns.3.0.0.bundle.min.js"></script>
<script src="js/lib/papaparse.5.5.3.min.js"></script>
<!-- Dashboard scripts -->

Result

Zero dashboard initialization errors. CSV parsing and time-series charts functional.

Pull request overview

This PR fixes dashboard runtime initialization errors on the static site by vendoring and loading missing client-side JavaScript dependencies (CSV parsing and Chart.js time adapter), and documenting the updated dependency set.

Changes:

Added locally hosted third-party libraries: Papa Parse (CSV parsing) and chartjs-adapter-date-fns (Chart.js time scale support).
Updated index.html and all language variants to include the missing libraries in the correct load order before dashboard scripts.
Updated security and architecture documentation to reflect the expanded locally hosted dependency set.

SECURITY_ARCHITECTURE.md

 - **External Dependencies:**
  - Chart.js v4.4.1 (hosted locally on CloudFront/S3 at js/lib/chart.umd.4.4.1.js)
  - chartjs-plugin-annotation v3.0.1 (hosted locally on CloudFront/S3 at js/lib/chartjs-plugin-annotation.3.0.1.min.js)
+  - chartjs-adapter-date-fns v3.0.0 bundle (hosted locally on CloudFront/S3 at js/lib/chartjs-adapter-date-fns.3.0.0.bundle.min.js) - for time-series charts
  - D3.js v7.9.0 (hosted locally on CloudFront/S3 at js/lib/d3.7.9.0.min.js)
+  - Papa Parse v5.5.3 (hosted locally on CloudFront/S3 at js/lib/papaparse.5.5.3.min.js) - for CSV parsing


The earlier CSP note in this section (around line ~237) still says only Chart.js, D3.js, and chartjs-plugin-annotation are locally hosted. Since this PR adds chartjs-adapter-date-fns and Papa Parse as additional locally hosted dependencies, that note should be updated to include them to avoid documentation drift/inconsistency within the same section.
