💾 Install

Stable releases are published on https://www.npmjs.com/package/zenroom that have a slow pace release schedule that you can install with

yarn add zenroom
# or if you use npm
npm install zenroom

🎮 Usage

The bindings are composed of two main functions:

zencode_exec to execute Zencode. To learn more about zencode syntax look here
zenroom_exec to execute our special flavor of Lua enhanced with Zenroom's special effects

Both of this functions accepts a mandatory SCRIPT to be executed and some optional parameters:

DATA
KEYS
CONF All in form of strings. This means that if you want to pass a JSON you have to JSON.stringify it before.

Both functions return a Promise.

To start using the zenroom vm just

import { zenroom_exec, zencode_exec, introspection } from "zenroom";
// or if you don't use >ES6
// const { zenroom_exec, zencode_exec } = require('zenroom')

// Zencode: generate a random array. This script takes no extra input

const zencodeRandom = `
  Given nothing
  When I create the array of '16' random objects of '32' bits
  Then print all data
`;

zencode_exec(zencodeRandom)
  .then((result) => {
    console.log(result);
  })
  .catch((error) => {
    console.error(error);
  });

// Zencode: encrypt a message.
// This script takes the options' object as the second parameter: you can include data and/or keys as input.
// The "config" parameter is also optional.

const zencodeEncrypt = `
  Scenario 'ecdh': Encrypt a message with the password
  Given that I have a 'string' named 'password'
  Given that I have a 'string' named 'message'
  When I encrypt the secret message 'message' with 'password'
  Then print the 'secret message'`;

const zenKeys = `
  {
    "password": "myVerySecretPassword"
  }
`;

const zenData = `
  {
      "message": "HELLO WORLD"
  }
`;

zencode_exec(zencodeEncrypt, {
  data: zenData,
  keys: zenKeys,
  conf: `color=0, debug=0`,
})
  .then((result) => {
    console.log(result);
  })
  .catch((error) => {
    console.error(error);
  });

// Lua Hello World!

const lua = `print("Hello World!")`;
zenroom_exec(lua)
  .then((result) => {
    console.log(result);
  })
  .catch((error) => {
    console.error(error);
  });

// to pass the optional parameters you pass an object literal eg.

try {
  const result = await zenroom_exec(`print(DATA)`, {
    data: "Some data",
    keys: "Some other data",
    conf: `color=0, debug=0`,
  });
  console.log(result); // => Some data
} catch (e) {
  console.error(e);
}

// code inspection is done via the `zencode_valid_input` primitive function or by a utility `introspect`

const introspection = await introspection(
  `Given I have a 'string' named 'missing'
  Then print the codec`
);
console.log(introspection); // => an object described as https://dev.zenroom.org/#/pages/how-to-embed?id=input-validation
