Note

This provider is currently in POC (proof-of-concept) status and under active development. Features and APIs may change without notice. Not intended for production infrastructure.

Camel case is the standard naming convention in JavaScript, Java, and many other programming languages. The function's smart word detection ensures proper capitalization regardless of whether the input is snake_case, kebab-case, or space-separated text.

Capabilities

This function enables you to:

• JavaScript identifiers: Convert text to valid JavaScript variable names
• API field names: Standardize JSON field names in camelCase format
• Configuration keys: Normalize configuration to camelCase for JavaScript/JSON
• Code generation: Generate camelCase identifiers programmatically
• Data transformation: Convert between naming conventions

Example Usage

locals {
  example_result = upper(
    # Function arguments here
  )
}

output "function_result" {
  description = "Result of upper function"
  value       = local.example_result
}

Signature

Arguments

Return Value

Common Patterns

API Field Mapping

locals {
  database_fields = ["user_id", "email_address", "created_at"]

  api_fields = [
    for field in local.database_fields :
    provider::pyvider::to_camel_case(field)
  ]
  # Result: ["userId", "emailAddress", "createdAt"]
}

JavaScript Configuration

variable "config_keys" {
  default = ["max retry count", "timeout seconds", "enable logging"]
}

locals {
  js_config = {
    for key in var.config_keys :
    provider::pyvider::to_camel_case(key) => "value"
  }
}
