Execute code
Run a script in a secure, isolated environment. Scripts can read from stdin and write to stdout or stderr. They can access input files, environment variables and command line arguments.
import Riza from '@riza-io/api';
// Untrusted Python code, either written by
// a customer or a LLM.
const python = `
import sys
import os
if 'DEBUG' in os.environ:
print('Reversing string...', file=sys.stderr)
stdin = sys.stdin.read()
print("".join(reversed(stdin)))
`;
const riza = new Riza();
async function main() {
const resp = await riza.command.exec({
language: "python",
code: python,
stdin: "Hello",
env: {
"DEBUG": "true",
}
});
console.dir(resp, {depth: null});
}
main();
{
"exit_code": 0,
"stdout": "olleH",
"stderr": "Reversing string..."
}
