Installation

npm install swiftjs-core zod

Quick Start

import { createApp } from 'swiftjs-core';

const app = createApp({ port: 3000 });

// Simple route
app.get('/', () => ({ message: 'Hello SwiftJS!' }));

// Route with params
app.get('/users/:id', (ctx) => ({
  userId: ctx.params.id
}));

// Route with validation
import { z } from 'swiftjs-core';
app.post('/login', (ctx) => {
  return { success: true };
}, {
  body: z.object({
    username: z.string(),
    password: z.string()
  })
});

app.listen();

File-based Routing

SwiftJS automatically maps files in your routes directory to URLs.

src/routes/
├── index.get.ts      → GET /
├── users.post.ts     → POST /users
└── users/[id].get.ts   → GET /users/:id

Advanced Features

Observability

import { observabilityPlugin } from 'swiftjs-core';
app.register(observabilityPlugin());

Background Jobs

import { jobsPlugin } from 'swiftjs-core';
app.register(jobsPlugin());
app.scheduler.addJob({
  name: 'cleanup',
  schedule: { cron: '0 0 * * *' },
  handler: async () => { /* ... */ }
});
