JXA Executor

A wrapper for osa module that allows to use it with promises (or async/await).

Usage

wrap(jxaFunction): create a async function to execute OSA script

use #wrap method to prepare a function that will execute OSA script and return a promise to the result:

const jxa = require('@mprokopowicz/jxa-executor');

const showDialog = jxa.wrap((message) => {
  const app = Application.currentApplication();
  app.includeStandardAdditions = true;
  app.displayNotification(message);
});

const main = async () => {
  await showDialog('Hello!');
  console.log('dialog closed');
};

main();

exec(jxaFunction, ...args): execute OSA script and get result

use #exec to invoke an OSA script and get a promise for returned result

const jxa = require('@mprokopowicz/jxa-executor');

jxa
  .exec((colors) => {
    const app = Application.currentApplication();
    app.includeStandardAdditions = true;
    return app.chooseFromList(colors, { withPrompt: 'What is your favorite color?' });
  }, ['red', 'green', 'blue'])
  .then((chosenColors) => {
    console.log(chosenColors);
  });
