Walkthrough

The PR updates configuration and dependencies, introduces a shared Webpack externals module, switches Webpack to use it, adds a root .cprc.json, updates Docker compose defaults, upgrades Go and JS deps, and removes the entire Rspack-based build setup including plugins and utilities.

Changes

Cohort / File(s)	Summary
Config version bump '.config/.cprc.json'	Version updated from 5.25.8 to 5.26.9.
Root configuration flags .cprc.json	New file with flags: bundleGrafanaUI=false, useReactRouterV6=true, useExperimentalRspack=false.
Webpack bundling/externals .config/bundler/externals.ts, .config/webpack/webpack.config.ts	Adds a dedicated externals config (direct, regex, and function-based legacy grafana/ prefix handling). Webpack config imports and uses it; adds pluginVersion to banners and replacements; minor formatting and template updates.
Rspack removal .config/rspack/BuildModeRspackPlugin.ts, .config/rspack/constants.ts, .config/rspack/liveReloadPlugin.js, .config/rspack/rspack.config.ts, .config/rspack/utils.ts	Deletes Rspack configuration, custom plugins (BuildMode, LiveReload), constants, and utilities (isWSL, getPackageJson, getPluginJson, getCPConfigVersion, hasReadme, getEntries). Removes exported entities.
Docker compose defaults .config/docker-compose-base.yaml	Updates Grafana image arg to 12.2.0, switches security option quotes, removes GF_DEFAULT_APP_MODE env var.
Go dependencies go.mod	Upgrades Go to 1.24.6 with toolchain 1.24.7; bumps grafana-plugin-sdk-go to v0.279.0; broad indirect dependency updates (Arrow, gRPC, OTEL, Prometheus, golang.org/x/*, etc.).
JS dependencies and scripts package.json	Updates Grafana packages to 12.2.0, adds @grafana/i18n, bumps ESLint config, changes test script to "jest --watch --onlyChanged".

Poem

I twitch my ears at builds anew,
Externals hop, Rspack bids adieu.
Webpack’s trail is crisp and clean,
Versions sprout like springtime green.
Go paths stretch, dependencies bloom—
Carrot banners waft perfume. 🥕✨

🔇 Additional comments (19)

.config/.cprc.json (1)

2-2: LGTM! Version bump aligns with PR objectives.

The version update from 5.25.8 to 5.26.9 is consistent with the PR title and objectives.

.cprc.json (1)

1-7: LGTM! Feature flags align with PR changes.

The configuration correctly sets:

• bundleGrafanaUI: false - aligns with the new externals configuration that externalizes Grafana UI packages.
• useReactRouterV6: true - enables React Router v6.
• useExperimentalRspack: false - consistent with the removal of Rspack configuration files mentioned in the PR summary.

.config/docker-compose-base.yaml (2)

10-10: LGTM! Grafana version bump aligns with package.json.

The Grafana version update to 12.2.0 is consistent with the dependency upgrades in package.json.

---

17-18: Cosmetic quote style change.

The change from double quotes to single quotes for security options is purely stylistic and does not affect functionality.

package.json (3)

38-38: LGTM! Enhanced test script for better DX.

The addition of --watch --onlyChanged improves the developer experience by enabling watch mode and running tests only for changed files.

---

47-47: LGTM! ESLint config minor version bump.

The update from ^8.0.0 to ^8.2.0 is a minor version bump that should be backward compatible.

---

98-102: LGTM! Grafana dependencies upgraded consistently.

All Grafana dependencies are upgraded to 12.2.0, and the new @grafana/i18n package is added for internationalization support. This aligns with the Docker compose Grafana version bump to 12.2.0.

.config/webpack/webpack.config.ts (7)

22-22: LGTM! Externals refactored to separate module.

Importing externals from a dedicated module improves maintainability and aligns with the new centralized externals configuration in .config/bundler/externals.ts.

---

26-26: LGTM! Plugin version extracted for reuse.

Extracting pluginVersion from package.json enables consistent version embedding in banners and replacements.

---

59-59: LGTM! Using imported externals configuration.

The configuration now uses the imported externals variable, replacing the previous hard-coded array.

---

136-137: Note: Console methods dropped in production.

The TerserPlugin configuration drops console.log and console.info in production builds. Ensure this aligns with your logging strategy.

---

163-164: LGTM! Enhanced banner with plugin identification.

The banner now includes both the plugin ID and version, improving traceability in production builds.

---

194-194: LGTM! Using pluginVersion for replacements.

The replacement now uses the extracted pluginVersion constant for consistency.

---

210-226: LGTM! Improved conditional plugin formatting.

The conditional inclusion of development plugins is reformatted for better readability.

.config/bundler/externals.ts (5)

1-7: LGTM! Proper typing for externals configuration.

The type definition using Configuration['externals'] ensures type safety for the externals export.

---

8-26: LGTM! Comprehensive static externals list.

The static externals list covers common dependencies for Grafana plugins, including UI libraries (React, Redux), utility libraries (lodash, moment), and visualization libraries (d3).

---

27-29: LGTM! Regex patterns for Grafana packages.

The regex patterns ensure that all imports from @grafana/ui, @grafana/runtime, and @grafana/data are treated as externals, which is correct for Grafana plugins that rely on the host Grafana instance to provide these packages.

---

32-42: LGTM! Legacy SDK prefix stripping handler.

The function-based external handler correctly:

• Checks if the request starts with the grafana/ prefix.
• Strips the prefix and returns the remainder as an external module.
• Calls the callback without a result if the prefix is not present, allowing other externals rules to process the request.

This ensures backward compatibility with legacy Grafana SDK imports.

---

5-43: No @grafana/i18n imports found—no externals update needed
Search across .ts/.tsx/.js/.jsx returned no references to @grafana/i18n, so the externals list requires no changes.
