# Fastify Now - a fastify plugin
File based routing for [fastify](https://www.fastify.io/) (v4).
**If you want to use this library with fastify v3, you should use version 2.X**
**If you want to use this library with fastify v2, you should use version 1.X**
## Example (see example folder)
For the given folder structure
```text
├── src
├── routes -- routes folder (can be changed)
| ├── user -- user resource endpoint folder
| | └──index.ts -- has POST method function
| | └──[id].ts -- has GET & PUT method functions
| └── index.ts
└── index.ts -- server file
```
will result:
```text
└── / (GET)
└── user (POST)
└── /
└── :id (GET)
:id (PUT)
```
Path params can also be prefixed with `:` E.g. `:id` instead of `[id]`
The plugin will ignore any `.{test|spec|bench}.js` files when loading routes
## Install
### Versions
The latest version is 2.X which supports fastify v3.
**If you want to use this library with fastify v2, you should use version 1.X**
```sh
npm install fastify-now
```
## Use
In your main server file (can see in example folder)
```javascript
import fastify from 'fastify';
import path from 'path';
import fastifyNow from 'fastify-now';
const server = fastify({ logger: true });
server.register(fastifyNow, {
routesFolder: path.join(__dirname, './routes'),
/**
* Can also provide a prefix
*/
// pathPrefix: '/api'
});
const PORT = Number(process.env.PORT) || 5000;
server.listen({ port: PORT }).then(() => {
// ...
});
```
In each route file, you need to export a function with a supported HTTP method as the function name, in uppercase letters
Currently supported HTTP methods: `GET, POST, DELETE & PUT`
In `/routes/user/:id/index.ts`:
```typescript
import { NowRequestHandler } from 'fastify-now';
export const GET: NowRequestHandler<{ Params: { id: string } }> = async (req, rep) => {
return { userId: req.params.id };
};
export const PUT: NowRequestHandler<{ Params: { id: string } }> = async (req, res) => {
req.log.info(`updating user with id ${req.params.id}`);
return { message: 'user updated' };
};
// with the server instance as the context (aka this)
export const POST: NowRequestHandler<{ Body: { name: string } }> = async function(req, res) {
// this = fastify instance
const [user] = await this.db.query(`SELECT * FROM users WHERE name = ${req.body.name}`);
// ... rest of code
}
```
Dynamic params are specified in the file name, or the folder name.
`routes/user/:id/index.ts` - will resolve to `/user/:id`
`routes/book/:id/chapter/:chapterId.ts` - will resolve to `/book/:id/chapter/:chapterId`
You can also add endpoint fastify opts.
For that, I created a new interface called `NowRequestHandler`.
in `/routes/user/index.ts`:
```typescript
import { NowRequestHandler } from 'fastify-now';
type Post = NowRequestHandler<{
Body: { name: string };
Params: { id: string };
Reply: { message: string } | { userId: string };
}>;
export const POST: Post = async (req, rep) => {
if (req.body.name === 'Jon Doe') {
/**
* in async function, you can return undefined if you already sent a response
* then it won't try to send a response again with the returned value;
*/
rep.status(400).send({ message: 'Name can not be Jon Doe' });
return;
}
return { userId: req.params.id };
};
POST.opts = {
schema: {
body: {
type: 'object',
properties: {
name: {
type: 'string',
},
},
required: ['name'],
},
},
};
```
