snoowrap

Class: RedditContent

RedditContent

A base class for content from reddit. With the expection of Listings, all content types extend this class. This class should be considered 'abstract', to the extend that JavaScript classes can be -- it should not be necessary to instantiate it directly.

new RedditContent()

Methods

fetch()

Fetches this content from reddit.

This will not mutate the original content object; all Promise properties will remain as Promises after the content has been fetched. However, the information on this object will be cached, so it may become out-of-date with the content on reddit. To clear the cache and fetch this object from reddit again, use refresh().

If snoowrap is running in an environment that supports ES2015 Proxies (e.g. Chrome 49+), then fetch() will get automatically called when an unknown property is accessed on an unfetched content object.

Returns:

A version of this object with all of its fetched properties from reddit. This will not mutate the object. Once an object has been fetched once, its properties will be cached, so they might end up out-of-date if this function is called again. To refresh an object, use refresh().

Type
Promise
Example
r.getUser('not_an_aardvark').fetch().then(userInfo => {
  console.log(userInfo.name); // 'not_an_aardvark'
  console.log(userInfo.created_utc); // 1419104352
});

r.getComment('d1xchqn').fetch().then(comment => comment.body).then(console.log)
// => 'This is a little too interesting for my liking'

// In environments that support ES2015 Proxies, the above line is equivalent to:
r.getComment('d1xchqn').body.then(console.log);
// => 'This is a little too interesting for my liking'

refresh()

Refreshes this content.

Returns:

A newly-fetched version of this content

Type
Promise
Example
var someComment = r.getComment('cmfkyus');
var initialCommentBody = some_comment.fetch().then(comment => comment.body);

setTimeout(() => {
  someComment.refresh().then(refreshedComment => {
    if (initialCommentBody.value() !== refreshedComment.body) {
      console.log('This comment has changed since 10 seconds ago.');
    }
  });
}, 10000);

toJSON()

Returns a stringifyable version of this object.

It is usually not necessary to call this method directly; simply running JSON.stringify(some_object) will strip the private properties anyway.

Returns:

A version of this object with all the private properties stripped

Type
object
Example
var user = r.getUser('not_an_aardvark');
JSON.stringify(user) // => '{"name":"not_an_aardvark"}'
