reviews

Retrieves a page of reviews for a specific application.

Note that this method returns reviews in a specific language (english by default), so you need to try different languages to get more reviews. Also, the counter displayed in the Google Play page refers to the total number of 1-5 stars ratings the application has, not the written reviews count. So if the app has 100k ratings, don't expect to get 100k reviews by using this method.

Options:

• appId: Unique application id for Google Play. (e.g. id=com.mojang.minecraftpe maps to Minecraft: Pocket Edition game).
• lang (optional, defaults to 'en'): the two letter language code in which to fetch the reviews.
• sort (optional, defaults to sort.NEWEST): The way the reviews are going to be sorted. Accepted values are: sort.NEWEST, sort.RATING and sort.HELPFULNESS.
• page (optional, defaults to 0): Number of page that contains reviews. Every page has 40 reviews at most.

Example:

var gplay = require('google-play-scraper');

gplay.reviews({
  appId: 'com.mojang.minecraftpe',
  page: 0,
  sort: gplay.sort.RATING
}).then(function(apps){
  console.log('Retrieved ' + apps.length + ' reviews!');
}).catch(function(e){
  console.log('There was an error fetching the reviews!');
});

permissions

Returns the list of permissions an app has access to.

• lang (optional, defaults to 'en'): the two letter language code in which to fetch the permissions.
• short (optional, defaults to false): if true, the permission names will be returned instead of permission/description objects.

Example:

var gplay = require('google-play-scraper');

gplay.permissions({appId: "com.dxco.pandavszombies"}).then(console.log);

Results:

[ { permission: 'modify or delete the contents of your USB storage',
    description: 'Allows the app to write to the USB storage.' },
  { permission: 'read the contents of your USB storage',
    description: 'Allows the app to read the contents of your USB storage.' },
  { permission: 'full network access',
    description: 'Allows the app to create network sockets and use custom network protocols. The browser and other applications provide means to send data to the internet, so this permission is not required to send data to the internet.' },
  { permission: 'view network connections',
    description: 'Allows the app to view information about network connections such as which networks exist and are connected.' } ]

Memoization

Starting with version 1.2.2 all methods are memoized by default, which means the results are cached so the request and response processing is skipped if a function is called again with the same arguments. The cached values are set to expire every 12 hours, which should work fine in most cases since Google Play usually refreshes the data once per day.

In case you want to force fresh results or want to avoid the cache memory consumption altogether, you can pass cache: false to any of the methods:

var gplay = require('google-play-scraper');

// first call will hit google play and cache the results
gplay.developer({devId: "DxCo Games"}).then(console.log);

// second call will return cached results
gplay.developer({devId: "DxCo Games"}).then(console.log);

// force fresh results (don't memoize)
gplay.developer({devId: "DxCo Games", cache: false}).then(console.log);

If you are interested in seeing how may requests are being done, you can run your node program with DEBUG=google-play-scraper.

Throttling

All methods on the scraper have to access the Google Play server in one form or another. When making too many requests in a short period of time (specially when using the fullDetail option), is common to hit Google Play's throttling limit. That means requests start getting status 503 responses with a captcha to verify if the requesting entity is a human (which is not :P). In those cases the requesting IP can be banned from making further requests for a while (usually around an hour).

To avoid this situation, all methods now support a throttle property, which defines an upper bound to the amount of requests that will be attempted per second. Once that limit is reached, further requests will be held until the second passes.

var gplay = require('google-play-scraper');

// the following method will perform batches of 10 requests per second
gplay.search({term: 'panda', throttle: 10}).then(console.log);

By default, no throttling is applied.
