A Python 3 to Deno + worker-vm binding, helps you execute JavaScript safely.
The module launches a Deno REPL server, which can be communicated with JSON. All JavaScript code are encoded in JSON and sent to the server. After the server executing the code in vm, the result is sent back to Python.
Follow the instruction here: https://docs.deno.com/runtime/manual/getting_started/installation
Also make sure deno command works as expected:
https://docs.deno.com/runtime/manual/getting_started/installation#testing-your-installation
pip install deno_vmMost of the APIs are bound to worker-vm.
Simple eval:
from deno_vm import eval
print(eval("['foo', 'bar'].join()"))Use VM:
from deno_vm import VM
with VM() as vm:
vm.run("""
var sum = 0, i;
for (i = 0; i < 10; i++) sum += i;
""")
print(vm.run("sum"))It is possible to do async task with Promise:
from datetime import datetime
from deno_vm import VM
js = """
function test() {
return new Promise(resolve => {
setTimeout(() => {
resolve("hello")
}, 3000);
});
};
"""
with VM() as vm:
vm.run(js)
print(datetime.now())
print(vm.call("test"))
print(datetime.now())http://deno_vm.readthedocs.io/
