In the past few years, more and more APIs have begun to follow the RFC5988 convention of using the
Link header to provide URLs for the next page. We can do this too and it’s quite easy.
Here is a function I recently wrote to do this for the simple case of a big array:
To demonstrate the usage, imagine you have defined a function
getMovies which provides a
movieList array you wish to paginate.
You have an express route
/movies which serves as the web API to your movie library.
You might create a paginated route like this:
Note that in most cases, you would not be paginating from a big array. This was my first time paginating a fairly large set which was not from a database. In the case of database access, your function won’t be so general since it will depend on using the database API to create an efficient query by offset and limit.
