Breaking Change Notice: Generated File Path & Naming Updates in Power Apps CLI v1.50

Preview Feature
This feature/API is currently in preview and is subject to change. Breaking changes may occur before general availability

Version 1.50 of the Power Apps CLI updates the directory layout and naming conventions of files generated by pac code add-data-source. These changes affect import paths and may break existing builds after upgrading.

Who Is Affected

Projects that:

• Were generated with CLI versions ≤ 1.47
• Use auto-generated models/services for data sources

Key Changes

1. dataSourcesInfo.ts relocated
   • Old: .power/appschemas/dataSourcesInfo.ts
   • New: .power/schemas/appschemas/dataSourcesInfo.ts
2. PascalCase adopted for generated model/service filenames
   • Old: accountsModel.ts, accountsService.ts
   • New: AccountsModel.ts, AccountsService.ts

Example Command

pac code add-data-source -a dataverse -t account

Directory Layout Comparison

Before (v1.47 and older)

MyApp
|   power.config.json
|
+---.power
|   +---appschemas
|   |       dataSourcesInfo.ts
|   |
|   \---schemas
|       \---dataverse
|               accounts.Schema.json
|
\---src
    \---generated
        |   index.ts
        |
        +---models
        |       accountsModel.ts
        |       CommonModels.ts
        |
        \---services
                accountsService.ts

After (v1.50 and newer)

MyApp
|   power.config.json
|
+---.power
|   \---schemas
|       +---appschemas
|       |       dataSourcesInfo.ts
|       |
|       \---dataverse
|               accounts.Schema.json
|
\---src
    \---generated
        |   index.ts
        |
        +---models
        |       AccountsModel.ts
        |       CommonModels.ts
        |
        \---services
                AccountsService.ts

Symptoms If Not Updated

• TypeScript compiler errors (Cannot find module './accountsService')
• Runtime resolution failures in Linux/CI (case-sensitive filesystems)
• Stale imports referencing removed lowercase filenames

Recommended Upgrade Steps

1. Upgrade CLI to v1.50.
2. Regenerate data sources (rerun relevant pac code add-data-source commands).
3. Search & replace imports pointing to old paths/names.
4. Run a full TypeScript build (npm run build) to surface missing modules early.
5. Remove any obsolete lowercase files left behind to avoid accidental shadowing.
6. Commit and push changes.

Notes

• No business logic changes—only file location and casing.
• Mixed environments (Windows dev / Linux CI) should verify casing carefully.

Next Steps / Reporting Issues

If you encounter unexpected regressions, include in your issue:

• CLI version
• OS / environment (Windows, WSL, Linux CI)
• Before/after tree snippet
• Exact error output
