Usage

API

Add $api to your svelte.config.js:

/** @type {import('@sveltejs/kit').Config} */
const config = {
  kit: {
    alias: {
      "$api": "./src/api",
    },
  },
};

Create the API endpoints in the structure like src/api.

// for example:
src
├── api
   ├── index.ts
   └── post
       ├── GET.ts
       ├── POST.ts
       ├── [...id]
          └── GET.ts
       └── search
           └── GET.ts
├── lib
   └── ...
└── routes
    └── ...
// file: src/api/index.ts
import { API } from "sveltekit-api";

export default new API(import.meta.glob("./**/*.ts"), {
  openapi: "3.0.0",
  info: {
    title: "Simple Post API",
    version: "1.0.0",
    description: "An example API",
  },
});
// file: src/api/post/[...id]/PUT.ts
import { Endpoint, z, error } from "sveltekit-api";
import { posts, type Post } from "../../db.js";

export const Query = z.object({
  password: z.string().optional(),
});

export const Param = z.object({
  id: z.string(),
});

export const Input = z.object({
  title: z.string(),
  content: z.string(),
  author: z.string(),
});

export const Output = z.object({
  id: z.string(),
  title: z.string(),
  content: z.string(),
  author: z.string(),
  date: z.string(),
}) satisfies z.ZodSchema<Post>;

export const Error = {
  404: error(404, "Post not found"),
  403: error(403, "Forbidden"),
};

export default new Endpoint({ Param, Query, Input, Output, Error }).handle(async (param) => {
  const post = posts.get(param.id);

  if (!post) {
    throw Error[404];
  }

  if (post.password && post.password !== param.password) {
    throw Error[403];
  }

  post.title = param.title;
  post.content = param.content;
  post.author = param.author;

  return post;
});

Call the API handler and OpenAPI generator in your routes like src/routes/api.

// file: src/routes/+server.ts
import api from "$api";
import { json } from "@sveltejs/kit";

export const prerender = true;

export const GET = async (evt) => json(await api.openapi(evt));
// file: src/routes/api/post/+server.ts
import api from "$api";

export const GET = async (evt) => api.handle(evt);
export const POST = async (evt) => api.handle(evt);
export const OPTIONS = async (evt) => api.handle(evt);
