chrome call

A really simple way to call the original chrome javascript API and return a Promise.

Install

npm i -S chrome-call

Usage

When you do:

var promise = new Promise(function(resolve,reject) {
  chrome.storage.local.get('key',function(value) {
    if(chrome.runtime.lastError){
      reject(chrome.runtime.lastError);
    }else{
      resolve(value);
    }
  });
});

It's equal to:

var promise = chromeCall('storage.local.get','key');

That's really simple, right?

Multiple arguments in callback

Most of chrome API only have one argument in callback, but someone not, such as chrome.hid.receive. In this situation, the value of promise will be an (real) Array:

chromeCall('hid.receive',connectionId)
  .then(function(args){
    Array.isArray(args); // true
    var reportId = args[0];
    var data = args[1];
  });

Scope

The global chromeCall search function on window.chrome, but you can use different scope:

var local = chromeCall.scope('storage.local'); // or chromeCall.scope(chrome.storage.local)
var promise = local('get','key');
