Axeom vs. Express

Express is the most popular web framework in history. However, its architecture was designed in 2010 for a Callback-heavy, Node-only world. Axeom represents the evolution of that architecture—built for the modern, type-safe, and multi-runtime web.

Routing & Handlers

Express relies on the legacy Node.js IncomingMessage and ServerResponse. Axeom uses the modern, Fetch-compliant Request and Response.

@axeom/framework


import  from '@axeom/framework';
const  = new ();

// Async-first, Fetch-compliant
.('/api', async () => {
  return "OK";
});

Express


import  from 'express';
const  = ();

// Callback-first, Node-only
.get('/api', (, ) => {
  .send("OK");
});

Validation & Type Safety

Express has no built-in validation. req.body is any. Axeom uses the native s schema engine to provide instant E2E safety.

@axeom/framework


import , {  } from '@axeom/framework';
const  = new ();

// Auto-typed via s.object()
.('/user', ({  }) => {
  return .; // Typed
}, {
  : .({ : .() })
});

Express


import  from 'express';
const  = ();

// Manual casting or mid-ware
.post('/user', (, ) => {
  const  = .body.name as string;
  .json({  });
});

File Upload

Express requires multer for multipart data. Axeom handles uploads natively with cross-runtime support via the upload plugin.

@axeom/framework


import , {  } from '@axeom/framework';
const  = new ();

// Integrated streaming
.('/upload', async () => {
  const {  } = .;
  await .storage.save(, `storage/${.}`);
  return "Saved";
}, { : .({ : .() }) });

Express


import  from 'multer';
import  from 'express';
const  = ();

// Requires Multer + FS logic
const  = ({ : 'uploads/' });
.post('/upload', .single('doc'), (, ) => {
  .send("Saved");
});

Lifecycle & Interceptors

Express uses an imperative middleware chain. Axeom uses a declarative Hook System (onRequest, onResponse) and .derive().

@axeom/framework


import  from '@axeom/framework';
const  = new ();

// Declarative Hooks
.(() => {
  if (!...('auth')) {
    return new ("Unauthorized", { : 401 });
  }
});

Express


import  from 'express';
const  = ();

// Imperative Middleware
.use((: any, : any, : any) => {
  if (!.headers.auth) return .status(401).end();
  ();
});

Encapsulation (Grouping)

Express routers must be manually instantiated and wired. Axeom groups are part of the fluent API.

@axeom/framework


import  from '@axeom/framework';
const  = new ();

// Fluent grouping
.('/v1', () => {
  .('/info', () => "v1");
});

Express


import  from 'express';
const  = ();

// Manual Router wiring
const  = .Router();
.get('/info', (, ) => .send("v1"));
.use('/v1', );

Error Handling

Asynchronous errors in Express can crash the process. Axeom handles all rejections globally in its flattened lifecycle.

@axeom/framework


import  from '@axeom/framework';
const  = new ();

// Global safety
.('/err', async () => {
  throw new ("Rejected");
});

Express


import  from 'express';
const  = ();

// Requires wrappers for async
.get('/err', async (, , ) => {
  try {
    throw new ("Rejected");
  } catch () {
    ();
  }
});

OpenAPI & Documentation

Documentation in Express is manual. In Axeom, it is a byproduct of your schemas via the @axeom/swagger plugin.

@axeom/framework


// Automatic Swagger
import  from '@axeom/framework';
import {  } from "@axeom/swagger";
const  = new ();

.(());

Express


// Manual JSDoc or JSON
/**
 * @swagger
 */
// const spec = swaggerJSDoc(options);
// app.use('/docs', ui.serve, ui.setup(spec));
