I also do contract work; so if you have a module you want built for NativeScript (or any other software projects) feel free to contact me nathan@master-technology.com.

Installation

Run tns plugin add nativescript-tracing from inside your main project's directory:

Usage

To use the tracing module you must first require() it from your project's node_modules directory:

var Tracing = require( "nativescript-tracing" );

Methods

Tracing(class, options);

Parameters

• class: your class you want to add tracing too
• (optional) options object:
  ** disableAddedFunction - This will disable adding the option "tracing" function that will disable/enable the console logging. ** ignore - array of functions that you don't want to add tracing too.
• RETURNS: Nothing

// my-page.js
var Sqlite = require( "/path/to/node_modules/nativescript-sqlite/sqlite" );
var Tracing = require( "/path/to/node_modules/nativescript-tracing/tracing");

Tracing(Sqlite, {ignore: ["close"], disableAddedFunction: true});


var db_promise = new Sqlite("MyTable", function(err, db) {
    if (err) { 
      console.error("We failed to open database", err);
    } else {
      // This should ALWAYS be true, db object is open in the "Callback" if no errors occurred
      console.log("Are we open yet (Inside Callback)? ", db.isOpen() ? "Yes" : "No"); // Yes
    }
});

db_promise.then(function(db) {
    // This should ALWAYS be true, db object is open in the "then"
      console.log("Are we open yet (Inside Promise)? ", db.isOpen() ? "Yes" : "No"); // Yes
      db.close();
   }, function(err) {
     console.error("We failed to open database", err);
   });

This should output something like:

• Starting Sqlite: MyTable, (callback)
• Starting isOpen
• Ending isOpen Are we open (callback)
• Starting isOpen
• Ending isOpen Are we open (Promise)
• ---- PLEASE note if we hadn't put the "close" in the ignore array it would have shown up here
• Ending Sqlite: MyTable
