Building a JSON:API endpoint in Rails

A versioned API controller that paginates, eager-loads, and serializes articles while avoiding N+1 queries.

https://t.co/vVpKgGlD7D

#ruby #rubyonrails

[Martin Sojka @msojka]

The private `pagination_meta` reads Kaminari's paging methods off the scope to build a tidy metadata hash, giving clients current page, neighbors, and totals in one consistent shape.

[Martin Sojka @msojka]

The single article is serialized with a richer `include` list — down to `comments.reactions` — so the response carries the full nested graph without extra round trips.

[Martin Sojka @msojka]

`show` preloads the same associations plus comment reactions, then `find` looks up a single article by `params[:id]`, again loading everything up front to keep queries flat.

[Martin Sojka @msojka]

`ArticleSerializer` renders the collection as JSON:API, explicitly including author, categories, and nested comment authors, and attaching pagination details via `meta`.

[Martin Sojka @msojka]

`.page(params[:page]).per(25)` is Kaminari syntax that slices the result set into pages of 25, reading the requested page straight from the query params.

[Martin Sojka @msojka]

The query starts from the `published` scope, then `includes` eager-loads authors, categories, comments with their authors, and attached cover images — preventing N+1 queries — before ordering newest first.

[Martin Sojka @msojka]

The controller lives under `Api::V1` and inherits from `BaseController`, namespacing the endpoint so a future `V2` can evolve independently. `index` lists articles.
