update-cdn

name	update-cdn
description	Update CDN module version for session-replay dependencies. Takes a version number as argument (e.g., `/update-cdn v2.7.0`). Updates CDN URLs in cdn-module.ts, picker.ts, picker-cdn.d.ts, cdn-module-types.d.ts, temporarily disables webpack frozen flag, runs build, then restores frozen flag and cleans up webpack.lock files.

When this skill is invoked, follow these steps:

0. Validate version argument

• The user MUST provide a version number as an argument (e.g., /update-cdn v2.7.0)
• If no version is provided, ask the user to provide one
• The version should be in format vX.Y.Z (e.g., v2.7.0)
• If the version doesn't start with 'v', prepend it (e.g., 2.7.0 becomes v2.7.0)

1. Show current state

• Read the current version from one of the CDN module files
• Display the current version and the target version to the user
• Ask for confirmation before proceeding

2. Update CDN URLs in source files

Update the version in the following files (replace old version with new version):

packages/session-recorder/src/session-replay/cdn-module.ts

Update the CDN URLs:

• https://cdn.observability.splunkcloud.com/o11y-gdi-rum/session-replay/vX.Y.Z/session-replay.module.legacy.min.js
• https://cdn.observability.splunkcloud.com/o11y-gdi-rum/session-replay/vX.Y.Z/background-service.html

packages/session-recorder/src/session-replay/cdn-module-types.d.ts

Update the module declaration URL:

• declare module 'https://cdn.observability.splunkcloud.com/o11y-gdi-rum/session-replay/vX.Y.Z/session-replay.module.legacy.min.js'

packages/web/src/utils/picker.ts

Update the CDN URL:

• https://cdn.observability.splunkcloud.com/o11y-gdi-rum/session-replay/vX.Y.Z/picker/picker.module.min.js

packages/web/src/utils/picker-cdn.d.ts

Update the module declaration URL:

• declare module 'https://cdn.observability.splunkcloud.com/o11y-gdi-rum/session-replay/vX.Y.Z/picker/picker.module.min.js'

3. Disable frozen flag in webpack configs

Temporarily set frozen: false in:

packages/session-recorder/webpack.config.js

Change:

experiments: {
  buildHttp: {
    allowedUris: ['https://cdn.observability.splunkcloud.com/'],
    cacheLocation: false,
    frozen: false,  // Changed from true
  },
},

packages/web/webpack.config.js

Change:

experiments: {
  buildHttp: {
    allowedUris: ['https://cdn.observability.splunkcloud.com/'],
    cacheLocation: false,
    frozen: false,  // Changed from true
  },
},

4. Delete old webpack.lock files

Remove the old lock files that contain outdated integrity hashes:

• packages/session-recorder/webpack.lock
• packages/web/webpack.lock

5. Run the build

Execute the build command from the repository root:

pnpm run build

This will:

• Fetch the new CDN resources
• Generate new integrity hashes
• Create new webpack.lock files with updated hashes

6. Restore frozen flag in webpack configs

Set frozen: true back in both webpack config files:

packages/session-recorder/webpack.config.js

experiments: {
  buildHttp: {
    allowedUris: ['https://cdn.observability.splunkcloud.com/'],
    cacheLocation: false,
    frozen: true,  // Restored
  },
},

packages/web/webpack.config.js

experiments: {
  buildHttp: {
    allowedUris: ['https://cdn.observability.splunkcloud.com/'],
    cacheLocation: false,
    frozen: true,  // Restored
  },
},

7. Verify the update

• Read the new webpack.lock files to confirm they contain updated integrity hashes for the new version
• Display the new integrity hashes to the user

8. Summary

Report:

• All files that were updated
• The old version and new version
• Confirm webpack.lock files have been regenerated
• Remind the user to review the changes before committing
