mfp

A third-party API for accessing MyFitnessPal diary data.

For it to work, you should set your diary privacy status to "public".

Installation

npm install mfp --save

Usage

var mfp = require('mfp');

mfp.fetchSingleDate(username, date, [fields], callback)

Asynchronously scrapes nutrient data from a user's food diary on a given date.

• username String
• date String with format YYYY-MM-DD
• fields String or Array
  • String 'all', which will fetch data for all nutrient fields
  • Array of nutrient field names, each a String. Allowable field names:
    • 'calories'
    • 'carbs'
    • 'fat'
    • 'protein'
    • 'cholesterol'
    • 'sodium'
    • 'fiber'
    • 'sugar'
• callback Function
  • the callback is passed a single argument data, which will be an Object whose keys are the nutrient field names and values are each a Number, as well as the date. Eg. { 'date': '2014-10-05', 'calories': 2078, 'carbs': 98, 'fat': 119, 'saturated fat': 35, 'protein': 153 }

Example 1:

mfp.fetchSingleDate('username', '2014-09-15', 'all', function(data){
  console.log(data);
});

Example 2:

mfp.fetchSingleDate('username', '2014-09-15', ['calories', 'protein', 'carbs', 'fat'], function(data){
  console.log(data);
});

mfp.fetchDateRange(username, dateStart, dateEnd, [fields], callback)

Asynchronously scrapes nutrient data from a user's food diary on a given date.

• username String
• dateStart String with format YYYY-MM-DD
• dateEnd String with format YYYY-MM-DD
• fields String or Array
  • String 'all', which will fetch data for all nutrient fields
  • Array of nutrient field names, each a String. Allowable field names:
    • 'calories'
    • 'carbs'
    • 'fat'
    • 'protein'
    • 'cholesterol'
    • 'sodium'
    • 'fiber'
    • 'sugar'
• callback Function
  • the callback is passed a single argument data, which will be an Object with the following format: Eg.

  { username: 'exampleUser',
    data: [
      { 'date': '2014-07-05', 'calories': 2078, 'carbs': 98, 'fat': 119, 'saturated fat': 35, 'protein': 153 },
      { 'date': '2014-07-06', 'calories': 2078, 'carbs': 98, 'fat': 119, 'saturated fat': 35, 'protein': 153 },
      { 'date': '2014-07-07', 'calories': 2078, 'carbs': 98, 'fat': 119, 'saturated fat': 35, 'protein': 153 }
    ]
  }
  

Example 1:

mfp.fetchDateRange('username', '2014-09-15', '2014-09-18', 'all', function(data){
  console.log(data);
});

Example 2:

mfp.fetchDateRange('username', '2014-09-15', '2014-09-18', ['calories', 'protein', 'carbs', 'fat'], function(data){
  console.log(data);
});

mfp.diaryStatusCheck(username, callback)

Asynchronously checks the privacy status of a user's food diary.

• username String
• callback Function
  • the callback is passed a single argument status, which will be a String with the following possible values:
    • 'public'
    • 'private'
    • 'invalid user'

Example:

mfp.diaryStatusCheck('username', function(status) {
  console.log(status);
});

mfp.apiStatusCheck(callback)

Asynchronously checks to see if all the API functions work correctly. They may cease to work because MyFitnessPal can change the way they present data on their site at any time.

• callback Function
  • the callback is passed a single argument errors, which will be an array containing the following possible strings:
    • 'diaryStatusCheck isn't working correctly for public profiles'
    • 'diaryStatusCheck isn't working correctly for private profiles'
    • 'diaryStatusCheck isn't working correctly for invalid usernames'
    • 'fetchSingleDate with all nutrients isn't working correctly'
    • 'fetchSingleDate with user-specified nutrients isn't working correctly'

Example:

mfp.apiStatusCheck(function(errors) {
  if (errors.length !== 0) {
    errors.forEach(function(error){
      console.log(error);
    });
  } else {
    console.log("There aren't any errors!");
  }
});
