With Middleware Stack
Test Code
RamAPI:
import { createApp, logger, cors } from 'ramapi';
const app = createApp({
adapter: { type: 'uwebsockets' },
});
// Middleware stack
app.use(logger());
app.use(cors());
app.use(async (ctx, next) => {
ctx.state.requestId = Math.random().toString(36);
await next();
});
app.get('/api/users', async (ctx) => {
ctx.json({
requestId: ctx.state.requestId,
users: [
{ id: 1, name: 'Alice' },
{ id: 2, name: 'Bob' },
],
});
});
await app.listen(3000);Fastify:
import Fastify from 'fastify';
import cors from '@fastify/cors';
const fastify = Fastify();
await fastify.register(cors);
fastify.addHook('onRequest', async (request, reply) => {
request.requestId = Math.random().toString(36);
});
fastify.get('/api/users', async (request) => {
return {
requestId: request.requestId,
users: [
{ id: 1, name: 'Alice' },
{ id: 2, name: 'Bob' },
],
};
});
await fastify.listen({ port: 3000 });Express:
import express from 'express';
import cors from 'cors';
import morgan from 'morgan';
const app = express();
app.use(morgan('tiny'));
app.use(cors());
app.use((req, res, next) => {
req.requestId = Math.random().toString(36);
next();
});
app.get('/api/users', (req, res) => {
res.json({
requestId: req.requestId,
users: [
{ id: 1, name: 'Alice' },
{ id: 2, name: 'Bob' },
],
});
});

Key insights:
- RamAPI middleware has minimal overhead (18.6% vs 20-21% for others)
- Pre-compiled middleware chains provide consistent performance
- Still 3.2x faster than Fastify with middleware
Real-World Application
Test Scenario
Simulates a typical API endpoint with:
- Authentication middleware
- Request validation (Zod schema)
- Database query (SQLite with better-sqlite3)
- JSON response
Test Code
RamAPI:
import { createApp, validate } from 'ramapi';
import { z } from 'zod';
import Database from 'better-sqlite3';
const db = new Database('benchmark.db');
const app = createApp({
adapter: { type: 'uwebsockets' },
});
// Auth middleware
const authenticate = async (ctx: Context, next: () => Promise<void>) => {
const token = ctx.headers.authorization;
if (!token || token !== 'Bearer valid-token') {
ctx.json({ error: 'Unauthorized' }, 401);
return;
}
await next();
};
// Route with validation
app.get(
'/api/users/:id',
authenticate,
validate({
params: z.object({
id: z.string().regex(/^\d+$/),
}),
}),
async (ctx) => {
const userId = parseInt(ctx.params.id);
const user = db.prepare('SELECT * FROM users WHERE id = ?').get(userId);
if (!user) {
ctx.json({ error: 'User not found' }, 404);
return;
}
ctx.json({ user });
}
);
await app.listen(3000);Results

| Hapi | 38,245 | 2.62ms | 6.12ms | 13.24ms |
Winner: RamAPI (uWebSockets) - 30.8% faster than Fastify, 2.0x faster than Express
Database Operations
Test Scenario
Heavy database operations with connection pooling:
- POST endpoint with validation
- Multiple database queries
- Transaction handling
- Error handling
Test Code
import { createApp, validate } from 'ramapi';
import { z } from 'zod';
import Database from 'better-sqlite3';
const db = new Database('benchmark.db');
const app = createApp({
adapter: { type: 'uwebsockets' },
});
const userSchema = z.object({
name: z.string().min(2).max(100),
email: z.string().email(),
age: z.number().int().min(18).max(120),
});
app.post(
'/api/users',
validate({ body: userSchema }),
async (ctx) => {
const { name, email, age } = ctx.body;
// Check if email exists
const existing = db
.prepare('SELECT id FROM users WHERE email = ?')
.get(email);
if (existing) {
ctx.json({ error: 'Email already exists' }, 409);
return;
}
// Insert user
const result = db
.prepare('INSERT INTO users (name, email, age) VALUES (?, ?, ?)')
.run(name, email, age);
// Fetch created user
const user = db
.prepare('SELECT * FROM users WHERE id = ?')
.get(result.lastInsertRowid);
ctx.json({ user }, 201);
}
);
await app.listen(3000);Results

| Hapi | 26,193 | 3.82ms | 8.91ms | 2.20ms | 1.62ms (42.4%) |
Key insights:
- Database is the main bottleneck (93% of time)
- RamAPI adds minimal overhead (6.8% with uWebSockets)
- When database-bound, framework choice matters less
- Still 19.6% faster than Fastify in database scenarios
