The Fellowmind Power Platform Developer Toolkit is a collection of reusable tools for Microsoft Power Platform and Dynamics 365 development. It includes PCF controls, model-driven app JavaScript web resources, Dataverse custom actions/plugins, and a utility for generating JavaScript constants from Dataverse metadata.
The toolkit is intended to speed up common implementation work, improve user experience in model-driven apps, and provide reusable building blocks for customer projects.

The JavaScript toolkit provides shared client-side helpers and reusable components for model-driven apps.
| Area | Path | Purpose |
|---|---|---|
| Shared library | Fellowmind.PowerPlatform.DeveloperToolkit.JS\Fellowmind.PowerPlatform.DeveloperToolkit.JS\source |
Core fmfi.PowerPlatform.DeveloperToolkit.JsLib helpers for form scripting, Web API usage, dialogs, navigation, custom pages, listeners, and other model-driven app tasks. |
| JS components | Fellowmind.PowerPlatform.DeveloperToolkit.JS\Fellowmind.PowerPlatform.DeveloperToolkit.JS\components |
Reusable higher-level form/grid components, including flow execution helpers and row copy helpers. |
| Localization resources | Fellowmind.PowerPlatform.DeveloperToolkit.JS\Fellowmind.PowerPlatform.DeveloperToolkit.JS\components\strings |
Component localization resources for supported languages. |
| Showcases | Fellowmind.PowerPlatform.DeveloperToolkit.JS\Fellowmind.PowerPlatform.DeveloperToolkit.JS\showcases |
Example form scripts that show how to use the JavaScript toolkit. |
The JS library is built around the global fmfi.PowerPlatform.DeveloperToolkit namespace and the model-driven app Xrm client API.
The Actions folder contains reusable server-side Dataverse functionality.
| Component | Type | Purpose |
|---|---|---|
ExecuteHttpTrigger |
Custom workflow activity | Reads a Power Automate HTTP trigger URL from configuration or environment variables, posts a JSON body to it, and returns the response. |
FetchXMLHelperAPI |
Plugin/custom API helper | Executes FetchXML and returns the result as JSON. |
GenerateReferenceNumber |
Custom workflow activity | Generates Finnish reference numbers, with optional check digit and international RF format support. |
MergeFiles |
Plugin/custom API helper | Merges Base64 encoded PDF files and returns the merged PDF as Base64. See Actions\MergeFiles\README.md. |
The actions/plugins are classic .NET Framework projects and are included in Actions\fellowmind.developertoolkit.plugins.sln.
- PCF controls use the
Fellowmindnamespace. - The expected Power Platform publisher prefix is typically
fmfi. - JavaScript web resources use the
fmfi.PowerPlatform.DeveloperToolkitnamespace. - Dataverse action/plugin parameter names are part of their public contract and should be preserved when updating components.
