Route Detection Patterns

Language	Framework	Example	Regex Pattern
TypeScript/JavaScript	Next.js	app.get('/users', handler)	`app.(get

TypeScript/JavaScript	Hono	app.get('/users', handler)	`app.(get
TypeScript/JavaScript	NestJS	app.get('/users', handler)	`app.(get
Python	FastAPI	@app.get('/users')	`@(app
Python	Flask	@app.get('/users')	`@(app
Python	Django	@app.get('/users')	`@(app
Go	chi	r.GET('/users', handler)	`.(GET
Go	gin	r.GET('/users', handler)	`.(GET
Go	echo	r.GET('/users', handler)	`.(GET
Go	net/http	r.GET('/users', handler)	`.(GET
Rust	Axum	.route('/users', get(handler))	`.route('".*?(get
Rust	Actix	.route('/users', get(handler))	`.route('".*?(get
Rust	Rocket	.route('/users', get(handler))	`.route('".*?(get
Java/Kotlin	Spring Boot	@GetMapping('/users')	`@(Get
Java/Kotlin	Javalin	@GetMapping('/users')	`@(Get
Java/Kotlin	Quarkus	@GetMapping('/users')	`@(Get
C#/.NET	ASP.NET Core	[HttpGet('users')]	`[(Get
C#/.NET	Minimal APIs	[HttpGet('users')]	`[(Get
Ruby	Rails	get '/users' do	`(get
Ruby	Sinatra	get '/users' do	`(get
PHP	Laravel	Route::get('/users', ...)	`Route::(get
PHP	Symfony	Route::get('/users', ...)	`Route::(get
PHP	Slim	Route::get('/users', ...)	`Route::(get
Elixir	Phoenix	get '/users', UserController, :index	`(get
Swift	Vapor	routes.get('users') { req in }	`routes?.(get
Scala	Akka HTTP	path('users') { get { ... } }	path\(['"]?([^'"]+)
Scala	Play	path('users') { get { ... } }	path\(['"]?([^'"]+)
Scala	Tapir	path('users') { get { ... } }	path\(['"]?([^'"]+)
C/C++	Crow	CROW_ROUTE(app, "/users")	CROW_ROUTE\([^,]+,\s*['"]([^'"]+)
C/C++	Drogon	CROW_ROUTE(app, "/users")	CROW_ROUTE\([^,]+,\s*['"]([^'"]+)
C/C++	Pistache	CROW_ROUTE(app, "/users")	CROW_ROUTE\([^,]+,\s*['"]([^'"]+)

Data Model Detection

ORM	Language	Detection
Prisma	TypeScript	schema.prisma file
SQLAlchemy	Python	Class definitions in models.py
Django ORM	Python	Class definitions in models.py
GORM	Go	Struct definitions with gorm tags
Diesel	Rust	table! macros in schema.rs
Hibernate	Java	@Entity annotations in .java
Entity Framework	C#	DbSet properties in DbContext
ActiveRecord	Ruby	Classes inheriting ApplicationRecord
Eloquent	PHP	Classes extending Model
Ecto	Elixir	schema definitions in .ex files

Custom Detection Rules

Add custom manifest and route patterns in usmconfig.json:

{
  "detection": {
    "manifests": [
      { "pattern": "**/my-framework.config", "language": "custom", "frameworks": ["my-framework"] }
    ],
    "routes": [
      { "framework": "my-framework", "pattern": "route\\.(get|post)\\(['"]([^'"]+)", "method_group": 1, "path_group": 2 }
    ]
  }
}
