The results parameter is output.
#+begin_src deno :results output const arr = [1, 2, 3]; console.log(arr); #+end_src #+RESULTS: : [ 1, 2, 3 ]
Specify variables.
#+begin_src deno :var foo="bar" baz='("qux") return {foo, baz}; #+end_src #+RESULTS: : { foo: "bar", baz: [ "qux" ] }
Run with --allow-net
. (equivalent to deno run --allow-net
)
#+begin_src deno :allow net :results output const response = await fetch("https://httpbin.org/get?hello=world"); const json = await response.json(); console.log(json.args); #+end_src #+RESULTS: : { hello: "world" }
More complex. (equivalent to deno run --allow-net=httpbin.org,example.com --allow-env
)
#+begin_src deno :allow '((net . (httpbin.org example.com)) env) :results output const response = await fetch(`https://httpbin.org/get?user=${Deno.env.get("USER")}`); const json = await response.json(); console.log(json.args); #+end_src #+RESULTS: : { user: "taiju" }
