Required Dependencies

The Tcl examples below require the following 3rd party libraries:

  • http package (built-in)
  • json package

Make sure these packages are installed in your environment before running the examples.

env object Environment variables (key-value pairs)
network_mode string "zerotrust" or "semitrusted"
ttl integer Timeout 1-900s (default: 60)
return_artifact boolean Return compiled binary
return_wasm_artifact boolean Return WebAssembly binary
