path = "path/to/build"
networking = false
stdout = false
stderr = false
environment_variables = false
max_pool_size = 1000
config = {}

• location specifies the path to the WASM file that contains custom hooks. You must provide a valid path and have read access to the file.
• networking enables network access with TCP and UDP sockets, name resolution and WASI HTTP bindings to the guest. TCP and UDP sockets work only if the guest language supports WASI preview 2 standard. Default value is false.
• stdout enables the guest to write to the standard output stream. Default value is false.
• stderr enables the guest to write to the standard error stream. Default value is false.
• environment_variables copies host environment variables to the guest. Default value is false.
• max_pool_size specifies the number of hook instances that can run concurrently. Default value is four times the number of CPU cores.
• config allows custom configuration for the extension. You must handle parsing and validation of the configuration in the extension initialization.
