Use this plugin to effortlessly expose a beautiful OpenAPI reference page from your ElysiaJS application with zero configuration. Just add the plugin to your Elysia app and you're good to go!

👉 Why use this over @elysiajs/swagger? This is a fork of @elysiajs/swagger with updated dependencies and a few opinionated changes. If @elysiajs/swagger suits your needs (and you don't need the latest version of Scalar API Reference), then by all means, use that instead.

Add it to your Elysia app

bun add elysiajs-openapi

Try it out

import { Elysia, t } from 'elysia'
import { openapi } from 'elysiajs-openapi'

const app = new Elysia()
    .use(openapi())
    .get('/', () => 'hi', { response: t.String({ description: 'sample description' }) })
    .post(
        '/json/:id',
        ({ body, params: { id }, query: { name } }) => ({
            ...body,
            id,
            name
        }),
        {
            params: t.Object({
                id: t.String()
            }),
            query: t.Object({
                name: t.String()
            }),
            body: t.Object({
                username: t.String(),
                password: t.String()
            }),
            response: t.Object({
                username: t.String(),
                password: t.String(),
                id: t.String(),
                name: t.String()
            }, { description: 'sample description' })
        }
    )
    .listen(8080);
