Jb is a JSON API template engine for Ruby on Rails that serves as a simpler and faster alternative to Jbuilder. Templates are plain Ruby code returning Hash or Array objects that get serialized to JSON, with no custom DSL to learn.

Use cases

• render JSON API responses in Rails views
• replace Jbuilder with a faster template engine
• build JSON payloads using plain Ruby hashes
• render JSON collections with working partials
• dynamically construct JSON attribute names
• generate top-level JSON arrays for index actions

When to choose

• you're on Rails and find Jbuilder's DSL awkward or slow
• you want JSON templates that are just Ruby code
• you need render_partial with :collection to actually render collections
• you prefer modern Ruby hash syntax that mirrors JSON

When to avoid

• you're not using Ruby on Rails
• you need a framework-agnostic JSON serializer
• your team already standardizes on Jbuilder or serializers like active_model_serializers
