Migrate
Migrate
Move to AponiaJS from NestJS or from a hand-written Elysia application.
AponiaJS borrows NestJS vocabulary and runs on Elysia, so both migrations are incremental. Start with the comparison for the framework you are coming from, then check what is not implemented yet before committing to a schedule.
From NestJS
Concept-by-concept mapping and the gaps that remain.
From Elysia
Keep the native application and adopt modules gradually.
Check the boundary first
Current limitations lists what the runtime does not do yet, and which CLI output is scaffold-only.
Still deciding rather than porting? Compare frameworks weighs AponiaJS against NestJS, AdonisJS, Elysia, Express, Fastify, and Hono before you commit to a migration.
