Plugin for [Elysia](https://elysiajs.com/) which autoload all routes in directory and code-generate types for [Eden](https://elysiajs.com/eden/overview.html) with [`Bun.build`](#bun-build-usage) and **Node adapter** support!
```bash
bun create elysiajs <directory-name>
```
and select `Autoload` in plugins
```bash
bun install elysia-autoload
```
```ts
import { Elysia } from "elysia";
import { autoload } from "elysia-autoload";
const app = new Elysia().use(await autoload()).listen(3000);
export type ElysiaApp = typeof app;
```
> [!IMPORTANT]
> We strictly recommend use `await` when registering plugin
>

```ts
// routes/index.ts
import type { ElysiaApp } from "app";
export default (app: ElysiaApp) => app.get("", { hello: "world" });
```

| Key | Type | Default | Description |
| -------- | ------------------------------------------ | ---------------------------------- | ----------------------------------------------------------------------------------- |
| pattern? | string | "\*\*\/\*.{ts,tsx,js,jsx,mjs,cjs}" | [Glob patterns](<https://en.wikipedia.org/wiki/Glob_(programming)>) |
| dir? | string | "./routes" | The folder where routes are located |
| prefix? | string | | Prefix for routes |
| types? | boolean \| [Types Options](
| schema? | Function | | Handler for providing routes guard schema |
| Key | Type | Default | Description |
| ---------- | ------------------ | ------------------- | --------------------------------------------------------------------------------------- |
| output? | string \| string[] | "./routes-types.ts" | Type code-generation output. It can be an array |
| typeName? | string | "Routes" | Name for code-generated global type for [Eden](https://elysiajs.com/eden/overview.html) |
| useExport? | boolean | false | Use export instead of global type |
```ts
// app.ts
import { Elysia } from "elysia";
import { autoload } from "elysia-autoload";
const app = new Elysia()
.use(
await autoload({
types: {
output: "./routes.ts",
typeName: "Routes",
}, // or pass true for use default params
})
)
.listen(3000);
export type ElysiaApp = typeof app;
```
```ts
// client.ts
import { treaty } from "@elysiajs/eden";
// Routes are a global type so you don't need to import it.
const app = treaty<Routes>("http://localhost:3002");
const { data } = await app.test["some-path-param"].get({
query: {
key: 2,
},
});
console.log(data);
```
`routes.ts` will be:
```ts
// @filename: routes.ts
import type { ElysiaWithBaseUrl } from "elysia-autoload";
import type Route0 from "./routes/index";
import type Route1 from "./routes/test/[some]/index";
declare global {
export type Routes = ElysiaWithBaseUrl<"/api", typeof Route0> &
ElysiaWithBaseUrl<"/api/test/:some", typeof Route1>;
}
```
Example of app with types code-generation you can see in [example](https://github.com/kravetsone/elysia-autoload/tree/main/example)
You can use this plugin with [`Bun.build`](https://bun.sh/docs/bundler), thanks to [esbuild-plugin-autoload](https://github.com/kravetsone/esbuild-plugin-autoload)!
```ts
// @filename: build.ts
import { autoload } from "esbuild-plugin-autoload"; // default import also supported
await Bun.build({
entrypoints: ["src/index.ts"],
target: "bun",
outdir: "out",
plugins: [autoload()],
}).then(console.log);
```
Then, build it with `bun build.ts` and run with `bun out/index.ts`.
You can bundle and then compile it into a [single executable binary file](https://bun.sh/docs/bundler/executables)
```ts
import { autoload } from "esbuild-plugin-autoload"; // default import also supported
await Bun.build({
entrypoints: ["src/index.ts"],
target: "bun",
outdir: "out",
plugins: [autoload()],
}).then(console.log);
await Bun.$`bun build --compile out/index.js`;
```
> [!WARNING]
> You cannot use it in `bun build --compile` mode without extra step ([Feature issue](https://github.com/oven-sh/bun/issues/11895))

### Usage of schema handler
```ts
import swagger from "@elysiajs/swagger";
import Elysia from "elysia";
import { autoload } from "elysia-autoload";
const app = new Elysia()
.use(
await autoload({
schema: ({ path, url }) => {
const tag = url.split("/").at(1)!;
return {
beforeHandle: ({ request }) => {
console.log(request.url);
},
detail: {
description: `Route autoloaded from ${path}`,
tags: [tag],
},
};
},
})
)
.use(swagger());
export type ElysiaApp = typeof app;
app.listen(3001, console.log);
```
