A Typescript compatible file based router for Node.js.

Made for sending json and getting json.

Insallation

$ npm i perstorp

Setup

Config

Make sure to create a file named perstorp.config.json in the root of your project.

It should look something like this:

{
  "cors": {
    "origin": "*",
    "methods": "GET,POST,PUT,DELETE",
    "headers": "Content-Type,Authorization"
  },
  "routesPath": "/api/v1/routes",
  "logger": true,
  "timeout": 1000,
  "typescript": true
}

• cors: You can read more about it here.
• routesPath: Is the path to the directory where you store your routes
• logger (optional): Defaults to false. Creates pretty logs from the activity on the server.
• timeout (optional): Time limit for a request
• typescript (optional): Needs to be set to true if you're using typescript.

Creating a server

import perstorp from "perstorp";

const PORT = 3000;

const app = perstorp();

app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});

Routes

In order to create a route you just create a new directory in the directory that you specified in the perstorp.config.json. Create a file called index.ts in the new directory.

Example

/api/v1/routes/hello/index.ts

Get function

The function has to have the name get

import type { ReqHandler } from "perstorp";

export const get: ReqHandler = ({ res }) => {
  res.json({ message: "World" });
};

Data

To get the data that is sent with the request just use the data parameter in your request handler.

import type { ReqHandler } from "perstorp";

export const post: ReqHandler = ({ res, data }) => {
  console.log(data); // Outputs json recieved in the request
  res.json({ message: "World" });
};

Search parameters

To get the search params for the request just use the params parameter in your request handler

import type { ReqHandler } from "perstorp";

export const post: ReqHandler = ({ res, params }) => {
  console.log(params); // Outputs search params
  res.json({ message: "World" });
};

Sending a JSON response

Use the json function on the res object

import type { Reqhandler } from "perstorp";

export const get: ReqHandler = ({ res }) => {
  res.json({ message: "World" }); // No need to stringify it. Perstorp does that for you.
};

Context

Use the context object to store things you might want to use in your handlers

index.ts

import perstorp from "perstorp";
import SomethingYouNeed from "somethingyouneed";

const PORT = 3000;

const somethingYouNeed = new SomethingYouNeed();

const app = perstorp({ somethingYouNeed });

app.listen(PORT, () => {
  console.log(`Server is running on port ${PORT}`);
});

the handler

import type { ReqHandler } from "perstorp";

export const get: ReqHandler = ({ res, context }) => {
  const { somethingYouNeed } = context;
  res.json({ message: "World" });
};
