In an earlier published tutorial, we’ve touched the topic of filtering documents by fields of nested objects using Thinky. With the native support of joins in RethinkDB, you’re able to structure your documents with relations between individual Thinky models. That means, splitting up your nested objects into separate …

Requesting data from API endpoints that might respond with large datasets is obviously bad practice. Breaking down massive information packets into smaller chunks is the idea behind pagination. There’s no de facto standard on how to implement pagination on server-side and therefore, clients have to adapt to the solution …

When working with OAuth 2 APIs, you have to manage access tokens and sometimes also refresh tokens. Generally, the access token is what you’ll use to authenticate your requests.
