Build be a backend with REST APIs using NodeJS, integrating multiple APIs like Pexels, Unsplash etc

Hi, Build be a backend with REST APIs using NodeJS, integrating multiple APIs like Pexels, Unsplash etc. Here's some outline the way I want it: 1. The REST APIs must provide a consistent interface like: i) Query for a specific string ii) Query for curated/most rated/liked photos etc iii) Return the data in a unified format from different API providers like Pexels, Unsplash iv) Should be flexible enough to integrate new API providers in further. 2. Should fetch the data from the multiple data sources and save them in a local DB Store 3. Take care of the Rate limiting of the different data sources APIs 4. Update the local database regularly when the APIs are fired 5. Whenever the REST APIs are invoked, the data must be returned from the local database, not from the APIs
