Building Functions with JavaScript

In FaasPlus, building functions with JavaScript involves creating endpoints within workspaces. Each function is written in an endpoint, providing a structured and secure way to manage and execute your code. Here’s a quick overview of how to get started with creating, writing, publishing, and monitoring your JavaScript functions.

Every function in FaasPlus is contained within an endpoint, and every endpoint is organized within a workspace. This structure ensures that functions remain organized and accessible based on team permissions and settings. Additionally, workspaces support configurable variables that can be used across all endpoints in that workspace, simplifying data management and allowing you to reference commonly used values, such as host URLs or configuration parameters.

When you create a new endpoint, FaasPlus automatically generates an example JavaScript code block based on the selected codebase. This example code provides a quick starting point, showing how to handle requests and return responses. You can edit this code directly in the endpoint editor to fit your function’s specific requirements.

Once the example code is generated, you can modify it as needed. FaasPlus includes built-in testing capabilities, allowing you to test your code directly in the editor. If the test runs successfully, you can publish your function, making it live and accessible via an automatically generated URL.

Endpoint URL Format: Your function will be available at a URL structured as {tenant_url}/{workspace_url}/{endpoint_url}. This format ensures each function has a unique, identifiable endpoint that can be called from external applications or services.

1. Create an Endpoint: Set up the endpoint within a workspace, selecting the codebase to initialize the example code.
2. Write Your JavaScript Function: Modify the generated code to implement your function’s logic. Access workspace variables as needed.
3. Test and Publish: Use the testing tools to validate your code. Once it passes testing, publish it to make the function accessible via its endpoint URL.
4. Monitor Your Function: View logs and performance metrics to ensure your function is running as expected, making adjustments as needed.

This step-by-step approach simplifies the function development process, allowing you to quickly deploy and manage scalable JavaScript functions.
