Getting started

Create webapp folder
```
mkdir webapp && cd webapp
```

Create main.ts

import { Fastro } from "https://raw.githubusercontent.com/fastrodev/fastro/master/mod.ts";
new Fastro().listen();

Run server
```
deno run -A main.ts
```
Open url
```
http://localhost:3000
```

How to add a handler

The structure will be like this:
```
webapp
├── main.ts
└── services
    └── hello.controller.ts
```
File and folder description:
- main.ts: Webapp entrypoint.
- services: Default folder for all handler files. You can change it via ServerOptions.
- services/hello.controller.ts: Endpoint handler. You can access it via URL: http://localhost:3000/hello.
Create entrypoint main.ts
```
import { Fastro } from "https://raw.githubusercontent.com/fastrodev/fastro/master/mod.ts";
const server = new Fastro();
server.listen();
```
- You can add ServerOptions on Fastro construtor to change default service folder, add url prefix, or enable cors.
- You can pass ListenOptions on listen function to change default port and address.

Create handler hello.controller.ts

import type { Request } from "https://raw.githubusercontent.com/fastrodev/fastro/master/mod.ts";

export const handler = (request: Request) => {
  request.send("hello");
};

Please note that the handler file name will be used as URL endpoint:

hello . controller.ts

Run server
```
deno run -A main.ts
```
Open url
```
http://localhost:3000/hello
```

Command line interface

You can also run your project using fastro command line interface (fastro-cli).

With this, you don’t need an entrypoint file (main.ts) anymore.

Install fastro-cli

deno install -A https://raw.githubusercontent.com/fastrodev/fastro/master/cli/fastro.ts

Run in development (HMR)

Modules will be reloaded when changes are made.
```
fastro serve
```
Run in production

You can change the app port also.
```
fastro serve --port 8080 --production
```
