reddinx is a reddit indexer. It saves on disk all posts of
a specific subreddit, in a format compatible with Algolia records.
const reddinx = require('reddinx');
// Launch an initial import of all posts since the subreddit creation
// Then, periodically (for example once every day), update the data with
It will get all posts metadata of the specified subreddit and save them on disk
./data folder. You don't need any API key, as both those API are free
Depending on the size of the subreddit, this can take up to several hours for an initial import and should be much faster on any subsequent incremental import.
The reddit API only allows access to the most recent posts, so to get all posts from the subreddit creation (which can be years old), we rely on a third party API: pushshift.io.
Pushshift provides an API to query all reddit posts, even very old ones. But its data is not fresh; it's a snapshot of what the post looked like at the time pushshift indexed it.
So once we got the list of all posts from pushshift, we query the reddit API to get the latest content, and save it on disk.
