Platform Overview
Each layer is independently useful but designed to compose into a complete production system — without glue code, without configuration fatigue, without dependency hell.
# One command
$ axil create my-api
$ cd my-api
$ axil run
⚡ Ready. Zero config.
Trie-based HTTP router with O(log n) matching. Async middleware chain. Body parsing, static files, and Server-Sent Events streaming. Built-in SyntaxilitY Response Manager for consistent JSON responses across every endpoint.
Production security headers via Helmet. Per-IP rate limiting with configurable windows (5 req/15 min on auth routes). CSRF protection. Input sanitization against XSS. Applied globally with one line.
ORM with PostgreSQL (NeonDB/SSL), MySQL, and SQLite drivers. Fluent query builder. Automatic migrations with SERIAL/AUTOINCREMENT per driver. JWT with HMAC-SHA256. Password hashing via scrypt. Full RBAC middleware.
Event bus with wildcard support. RFC 6455 WebSocket server with rooms and broadcast. Message queue with exponential backoff and cron scheduler. Circuit breaker with fallback. Prometheus metrics. W3C distributed tracing.
Provider-agnostic LLM abstraction for OpenAI, Anthropic, Gemini, and Ollama (local, no API key). RAG pipeline with vector store and document indexing. AI agents with tool calling and max iteration control. MCP client.
Multi-tenant isolation middleware. Immutable audit logging. Feature flags with percentage rollout. Docker Dockerfile generation. Kubernetes deployment + HPA manifests. Memory leak detection with auto-fix and GC optimization.
Browser-based development dashboard that launches automatically with axil run. API route explorer with Try It Out. Database browser with schema inspection, data grid, pagination, and CSV export. SQL query editor. WebSocket and SSE live monitors. Postman, Insomnia, and OpenAPI collection export. QR code for mobile access.
Developer Experience
Every import in this example comes from the same ecosystem. No third-party auth library. No separate validation package. No external security middleware. Full TypeScript inference from request to response.
CLI
1import { Application, cors } from '@axiljs/core'
2import { loadEnv, defineConfig } from '@axiljs/config'
3import { helmet, rateLimit } from '@axiljs/security'
4import { JWT, authenticate, requireRole } from '@axiljs/auth'
5import { v, validate } from '@axiljs/validation'

7// Typed env validation — fails fast on startup
8loadEnv()
9const config = defineConfig({
10 PORT: { type: 'number', default: 3000 },
11 JWT_SECRET: { type: 'string', required: true }
12})
13
14// One application, zero configuration
15const app = new Application({ server: { port: config.PORT } })
16const jwt = new JWT(config.JWT_SECRET)
17
18// Security applied globally in three lines
19app.use(helmet())
20app.use(cors())
21app.use(rateLimit({ max: 100, windowMs: 60000 }))
22
23// Auth + validation composed per route
24app.post('/users',
25 authenticate(jwt),
26 requireRole('admin'),
27 validate({ body: v.object({
28 name: v.string().min(2).max(100),
29 email: v.string().email(),
30 role: v.enum(['admin', 'user']),
31 }) }),
32 async (req, res) =>
33 res.created(req.body, 'User created')
34)
35
36app.listen()Built-in Response Manager
The SyntaxilitY API Response Manager is built directly into the res object. No imports needed. Every response is automatically formatted with status codes, typed messages, and pagination metadata.

Architecture Support
AxilJS is designed as a complete backend ecosystem rather than a single-purpose HTTP framework. Build monoliths, modular systems, distributed services, event-driven platforms, and AI-native applications using the same ecosystem.
A structured Model-View-Controller architecture for applications that benefit from explicit separation of responsibilities.
npx axil create blog --architecture mvcArchitecture
A complete application deployed as a single unit while retaining access to the full AxilJS ecosystem.
npx axil create shop --architecture monolithArchitecture
Organize a large application into isolated business modules without introducing distributed-system complexity.
npx axil create platform --architecture modularArchitecture
Decompose applications into independently deployable services with communication, resilience, and observability built into the ecosystem.
npx axil create platform --architecture microserviceArchitecture
Build asynchronous and reactive systems using the AxilJS event bus, queues, schedulers, retries, and background workers.
npx axil create worker --architecture event-drivenArchitecture
Build AI-powered backend systems with LLM providers, RAG pipelines, agents, embeddings, vector stores, and MCP.
npx axil create ai-app --architecture aiArchitecture
Same ecosystem. Different architecture.
Core, Security, ORM, Auth, Validation, Testing, Events, Queue, Observability, AI, Cloud, and Memory modules work across your application architecture.
